Equis Energy for $5 Billion is Now Partner With GIP-Led
A consortium led by US fund Global Infrastructure Partners (GIP) has agreed to buy Singaporeheadquartered renewable energy company Equis Energy for a record $5 billion including debt. Equis Energy has 11,135 mw of green energy capacity—including commissioned, under construction and under-development projects—across seven countries. The company has commissioned solar and wind projects of about 1,100 mw in the Asia Pacific region, of which 544 mw are in India. Its assets had been been on the block for several months. In what is the largest deal in the clean energy sector,
the GIP-led consortium will pay $3.7 billion in cash to Equis and take over its liabilities of $1.3 billion. “The transaction is the largest renewable energy generation acquisition in history and positions GIP as a dominant renewable energy developer in the key OECD growth markets of Australia and Japan, as well as across India and South-East Asia,” Equis said in a press release. The other members of the consortium include Canada’s Public Sector Pension Investment Board, one of its largest pension investment managers, CIC Capital Corporation, also a Canada-based private equity firm, and China’s sovereign wealth fund, China Investment Corporation. In India, Equis has 414 mw of wind projects, including two in Andhra Pradesh (100 mw and 54 mw), two in Madhya Pradesh (108 mw and 26 mw), and one each in Maharashtra, Karnataka and Gujarat (30 mw, 46 mw and 50 mw, respectively). It has a 130 mw solar
project in Telangana and is close to commissioning another 130 mw solar project in Karnataka. The company has another 356 mw under development in the country, taking its total renewable energy capacity (commissioned and under development) in India to 900 mw across 14 projects. The other countries in which Equis has projects, either commissioned or under construction, are the Philippines, Japan, Thailand, Indonesia, Australia and Taiwan. A number of Indian companies, including the Adani Group and Hero Future Energy, had been in the fray for Equis’ Indian assets. Some industry executives said that since none of the consortium partners has a presence in India’s renewable energy sector, the Indian assets will probably be resold. Equis’ decision to sell had sparked a global race to acquire its assets. Among the others that had evinced interest included Royal Dutch Shell and Japan's Softbank; financial services giant Orix Corporation in Japan and Dutch pension fund APG; the Adani Group and Qatar-based Nebras Power, US-based PE fund I Squared Capital along with Thailand's Electricity Generation Plc and Japan's Mitsubishi; France's energy major Engie and China's State Power Investment Corporation.
Govt Working to Make Obligations Under Power Purchase Agreement Binding: Power Minister
The government is working to make obligations under power purchase agreement (PPA) statutory binding, ensuring all discoms have PPAs to cover 100 percent requirement, Power Minister R.K. Singh has said.
"I have called a meeting of energy ministers of all states on November 10-11, I will tell them that I am going to make obligations under PPAs statutory binding, that all discoms must have PPAs to cover 100 per cent of requirement and that there will be penalties for not paying electricity bills on time," Singh said at the ASSOCHAM Global Investors' India Forum. Singh said that the government will ensure timely payment of electricity bills with the adoption of smart metering or pre-paid metering. "I am also going to provide in the law penalties if power bills are not paid promptly and the amended law will also provide that the RPOs (renewable purchase obligations) will be obligatory, it will be a statutorily legal compulsion," he said. The government is not going back on its commitment to generate 30% of its energy from renewable sources, he added.
Singh said that green energy sources are eventually going to gather an edge over fossil fuels, largely petroleum. This however, would require investment in technology, grid balancing, green corridors, in peaking power, he said. "By and large we see electricity emerging as the primary source of energy as electric mobility is more efficient than mobility by petrol or diesel, the only thing required is the prices of the battery of storage systems to come down," Singh said. He added that he had called a meeting of all vehicle manufacturers and storage system providers, asking them to invest in these sectors. Singh said that power demand in India is going to grow because coverage is going to expand and is going to be universal. "We are connecting all villages by this December though the target is for March."

Gujarat Wind Power Auction on Hold: HC
The Gujarat High Court has passed an interim order restraining the state from holding its first wind energy auction scheduled for November 1. The court acted in response to a petition by Indian Wind Energy Association, which said the Gujarat State Electricity Commission’s permission to hold the auction was contrary to law because the Centre has not issued guidelines for the sale of state wind projects. The state distribution company, Gujarat Urja Vikas Nigam Ltd., has been stopped from going ahead with the auction until the matter is disposed of. The next hearing is scheduled for October 30. “It is clarified that no further orders approving the bidding process... shall be passed by the commission, pending the present petition,” the court said. The association said guidelines governing wind auctions by states had not yet been announced by the Centre, as required by the Electricity Act, 2003. The auction of 500 MW of wind projects in Gujarat was originally slotted in mid-July and was delayed for various reasons. The GERC was ambivalent about giving permission for the sale before sanctioning it on October 6. GUVNL set a deadline of October 24 for technocommercial bids, which have to pass muster before bidders are allowed to participate in the price
auction, which was scheduled for November 1. Following the court order, the last date for techno-commercial bids has been extended to November 3 and no date has been set for the actual auction. Technocommercial bids for about 1,500 MW of wind projects have already been submitted for the auction, according to people familiar with the matter. GUVNL officials were unwilling to respond to the court order. However, a government official said: “They have talked to lawyers and are confident that the reverse auction will eventually take place.” A wind power developer confirmed that they had been told to keep filing their technocommercial bids. “We were given to understand that the auction process is only temporarily on hold,” he said. The wind energy association had earlier petitioned the Madras High Court against Tamil Nadu’s 500 MW wind auction in August on similar grounds. The court allowed the sale to go ahead, stipulating that allocation letters to winners should not be issued until it ruled on the matter. In mid-September, IWEA voluntarily withdrew its petition. Wind energy tariffs declined in auctions of 1,000 MW each held by an arm of the Ministry of New and Renewable Energy in February and October. At the first auction, the tariff fell to Rs 3.46 per unit, lower than the prevailing rates of Rs 4-6 per unit set by various state power regulators. At the second auction, the winning bid dropped further to Rs 2.64 per unit. Lens on foreign firms investing in power sector A high-level panel will look at possible checks on foreign firms investing in the Indian power sector, a move aimed at preventing cyberattacks on the electricity grid. This comes about two months after the eastern electricity grid suffered a malware attack, allegedly from China.
Overseas firms eyeing investments in power plants in the country may have to undergo security clearances and may be mandated to employ majority Indian nationals including at top managerial positions, a senior government official said. The restrictions are in line with India’s commitments to WTO, said the official, who did not wish to be identified. The panel being set up by the government will study recommendations of a report on cybersecurity issues in the power sector prepared by a committee that includes officials of the Central Electricity Authority (CEA), ministries of power and commerce, and industry associations. The committee has also recommended allowing only those foreign companies that have minimum work experience in India, and seeking details of origin of raw material used in the projects. The report has recommended that firms with base in countries that do not allow imported goods without testing should be treated similarly in India. on reported that the government will lay down product-wise technical specifications and regulations to ensure that only audited and tested equipment are connected to the electricity grid. The regulations will be country neutral and will aim at boosting local manufacturing. The proposed committee will be headed by a senior executive of the CEA and include senior officials from the power, commerce and IT ministries, executives from state-run firms such as NTPC and PGCIL, and other industry representatives. It will suggest ways to secure the Indian electricity grid from malware and encourage domestic manufacturers. “This is one of the first steps being taken to protect the electricity grid. The government has realised and recognised the need for such measures in the wake of a recent attack on eastern power grid, reportedly from China,” another government official said on condition of anonymity. Most private power generators prefer Chinese power equipment that comes with cheaper line of credit. Chinese firms such as Dongfang Electric Corporation, Harbin Electric International Company and Shanghai Electric have bagged a chunk of equipment orders from Indian power developers in the past.
Telengana Places Rs 20,400 Crore Contract on BHEL Telangana State Power Generation Corporation Limited (TSGENCO) has placed Rs 20,400 crore order on BHEL The contract for Yadadri thermal power plant comprising five units of 800 MW supercritical sets, is not only the single-largest order for BHEL but also
the highest value order ever placed in the power sector in India, an official statement said. The project has been accorded environmental clearance by the Ministry of Environment, Forest and Climate Change (MoEF&CC) and would be compliant with the revised emission norms, it said.
To be set up on Engineering, Procurement and Construction (EPC) basis by BHEL, the project is located at Damaracherla in Nalgonda district of Telangana.

ABB Looks Towards India as a Growth Market for Microgrid Solutions
Global power and automation player ABB is looking at India as a potential location for its microgrid solutions given the country’s huge requirement for electrification, and the government’s push for renewable energy, Markus Bruegmann, the company’s global product group manager for microgrids, Power Grids division, said. “In emerging markets, it’s firstly about the access to electricity, and reducing certain fuel cost because today from India so many people are not electrified and they run on diesel. This is a driver for the emerging markets. We see it (India) as a growth market, as far as microgrids is concerned,” he said. Bruegmann added that ABB’s global engineering solutions are largely dependent on a team in India, which grew twice its size from last year and is expected to double again. “We have installed in India an engineering team which works for all global microgrid applications because we find in India well educated engineers, so I use this hub to serve all of my units. So, whatever needs to be engineered will be engineered first there, from there it goes back and gets localized. We are using India quite heavily and we have invested already a lot of resources here,” he said.
Microgrids are being looked at as a potential solution for feeding India’s electrification needs, and powering its islands, Bruegmann added. ABB has developed a micro grid system to integrate solar energy and supply power to Robben Island, a few km off the coast of Cape Town. The project was developed for an EPC SOLA Future Energy. A similar solution can be considered for islands in India, Bruegmann said. ITI lowest bidder for 50 lakh smart meter auction by EESL State-run ITI Ltd has emerged as the lowest bidder for 50 lakh smart meters quoting a rate of Rs 2,503 per unit, followed by Genus Power and KEONICS in a reverse auction by EESL. Earlier this month, L&T had quoted the lowest price for smart meters at Rs 2,722 per unit, which was 40-50 per cent lower than the current market price. State-run Energy Efficiency Services Ltd (EESL) has achieved a further price reduction in the procurement of 50 lakh smart meters on the basis of a reverse auction of the tender conducted last week, a Power Ministry statement said. According to the statement, ITI has emerged as the lowest bidder (L1 bidder) in this reverse auction, followed by Genus Power and KEONICS.
ITI quoted the lowest price of Rs 2,503 per unit. Now the total procurement cost of 50 lakh units has been reduced by Rs 132 crore due to reverse auction. The bidding has brought the price down from Rs 2,722 to Rs 2,503 per smart meter which is a reduction of 8 per cent from the previous tender quote, it said. A total of seven companies were invited for the reverse auction. The lower price will further benefit the end consumers. As per the government guidelines, EESL will invite Genus Power (L2) and KEONICS (L3) to match the L1 price. It further said after L2 and L3 match the L1 price, the EESL will split the procurement of a single metre between three parties in the ratio of 50:30:20. The meters will be installed over a period of three years in a phased manner in Uttar Pradesh and Haryana. The procurement conducted by the EESL, which comes under Ministry of Power, is the world s largest single smart meter procurement. As many as 40 lakh such meters will be deployed in UP and the remaining 10 lakh in Haryana. Smart meters are a part of the overall Advanced Metering Infrastructure Solutions (AMI) aimed at better demand response designed to reduce energy consumption during peak hours. The overall AMI solution will also have a system integrator who will be responsible for meter installation, data storage on cloud, preparing dashboards, etc. The bids for the system integrator are expected to open on October 31, 2017. EESL is procuring smart meters and services of the system integrator with 100 per cent investment and the utilities will make zero-investment. The repayment to EESL will be through savings resulting from enhanced billing efficiency, avoided meter reading costs, etc. It is said the average cost of meter reading is Rs 40 per meter, which will be completely avoided.
Railways' First Set of Solar Plants to be Launch The Railway's first set of solar plants with a total capacity of 5 megawatt peak (MWp) will be launched here tomorrow by Railway Minister Piyush Goyal. The plants on the roof tops of Hazrat Nizamuddin, New Delhi, Anand Vihar and Delhi railway stations will generate 76.5 lakh units of solar power cumulatively per year and shall meet about 30 per cent of the 14 NOVEMBER 2017 ||ELECTRICAL MIR R OR
energy requirement of these stations, the officials said. Through the project, the railways will save Rs 421.4 lakh annually and will reduce 6082 tonnes of CO2 emissions. This project is a part of the government's National Solar Mission in which Indian Railways plans to commission 1000 MWp solar plants across its network.
The project was awarded in December 2016. The cost of the project is Rs.37.45 crore and has been bought in by the developer under the PPP model. The developer will also maintain it for 25 years and Railways will only pay energy consumed at Rs 4.14 per unit, said the officials.

Sourced Equipment Can be Tested for Malware Grid
The government plans to lay down stringent regulations for multi-level checks on equipment imported for the domestic power distribution sector to prevent the electricity grid from cyber attacks. A senior government official said that the government will lay down product-wise technical specifications
and regulations to ensure that only audited and tested equipment are connected to the electricity grid. The regulations will be country neutral and will aim at boosting local manufacturing, said the official, who did not wish to be identified. In addition to this, the government plans to develop a testing facility for cybersecurity where sourced equipment can be tested for malware before installation and periodically after commissioning. The Central Electricity Authority will amend the regulations so that only authentic equipment is installed in the grid, the official said. “The authority
will also lay down testing standards and procedures for cyber security compliance,” he said. Cyber attacks on the electricity grid could have a debilitating impact on national security, governance, economy and social well-being of the nation. Transportation, banking, telecom and defence are the other critical sectors. The domestic electrical equipment industry has been raising concerns over contracts awarded to Chinese companies for installation of supervisory control and data acquisition systems (SCADA) for power distribution that can lead to foreign control over a sector critical to the country’s growth. Many contracts for implementation of SCADA—for better power distribution and management— in Tamil Nadu, Rajasthan, Madhya Pradesh and Puducherry have been bagged by foreign power equipment companies.
Hero Group Set to Buy Wind Energy Assets of Bhilwara
The Hero Group is close to acquiring almost the entire wind energy portfolio of the LNJ Bhilwara Group, helping the buyer emerge as one of the biggest players in the rapidly growing sector that has seen large M&A deals in recent months. The acquisition, on the verge of being finalised, follows several deals since last year in the sector, involving the Tatas, Sun Edison, CLP Holdings and other companies. Several Indian and foreign groups including the Adanis and Softbank are also considering opportunities in the sector, which has expanded rapidly as companies have bid aggressively with razor-thin margins to grab auctioned projects by offering rockbottom tariffs. Hero Future Energies (HFE) will acquire the portfolio of Bhilwara Energy Ltd (BEL) in an allcash deal, 16 NOVEMBER 2017 ||ELECTRICAL MIR R OR
sources close to the development said. The size of deal is not yet known as some details remain to be worked out. It is acquiring 83.5 MW of wind projects out of BEL’s total of 103.5 MW across two states – a 49.5 MW project in Satara, a 14 MW one in Bhendewade, both Maharashtra, and a 20 MW project in Jaisalmer, Rajasthan. “The remaining 20 MW will stay with BEL because of some internal issues,” one of the sources said. This will take the Hero Group’s total portfolio to around 1200 MW, half of it in wind and the rest in solar energy, making it one of the largest renewable energy companies in the country. However, it is still well behind ReNew Power, whose portfolio crossed the milestone of 2000 MW in March this year and Tata Power Renewable Energy, which following its acquisition of Welspun Energy’s renewable assets of 1140 MW in June 2016, now has a 2300 MW solar and wind portfolio. But HFE has set itself a publicly disclosed target of achieving 3500 MW by 2020, in which acquisitions are expected to play a vital part. BEL’s wind assets have been on the block since February, with the company preferring to concentrate on its large hydro-electric projects in Himachal Pradesh, Arunachal Pradesh and Nepal. While its
Rajasthan wind project is a group captive one, the two in Maharashtra supply power to state discoms under longterm 25-year power purchase agreements (PPAs). “The projects are barely four or five years old,” said the source. “There are still 20 or more years of the PPA to go.” The past 18 months have seen a number of acquisitions in this sector with Tata Power’s buyout of Welspun Energy’s renewable portfolio for Rs 9,249 crore in June 2016 being the biggest. Another major acquisition was that of Greenko Energies taking over the Indian assets of 500 MW of the bankrupt US-based SunEdison, once the largest renewable energy company in the world, for $392 million (Rs 2,607 crore) in October 2016. In June this year, CLP India, a wholly owned subsidiary of Hong Kong-based CLP Holdings, bought a 49% stake in Suzlon’s solar subsidiary, SE Solar, for Rs 73.5 crore. In July, Vector Green Energy, the renewable energy arm of IDFC Alternatives, acquired 190 MW of solar assets across seven Indian states from US-based First Solar for an undisclosed amount. Currently, a number of companies, global and Indian, including HFE and the Adani Group, are vying to acquire the Indian renewable energy assets of Singapore-based Equis Energy, which has put its entire renewable energy portfolio across several Asian countries up for sale. Again, private equity fund Actis Llp has been seeking to divest its stake in Ostro Energy’s renewable portfolio for a number of months. ||www.electricalmirror.net||

Punjab as Power Tariff Has Been Increases
Consumers will have to shell out more for electricity as sectoral regulator Punjab State Electricity Regulatory Commission (PSERC) announced a hike in power tariff by 9.33 per cent for 2017-18. However, opposition parties AAP, SAD and BJP condemned the hike in power tariff, saying the Congress government had yet again "deceived" people by increasing tariff for both domestic and industrial supply. The new tariff order will be implemented with retrospective effect from April 1 this year. Although the increase in electricity charges will be recovered from consumers in installments over a period of nine months, said PSERC chairperson Kusumjit Kaur Sidhu. As per new tariff, the tariff for domestic consumers has been increased between 7 per cent and 12 per cent. The proposed increase has been in the range of 46 paise per unit to 80 paise per unit. For industrial sector, the power tariff has been increased by 8.50 per cent to 12 per cent while for commercial category, the electricity rates have been jacked up by 8 to 11 per cent, PSERC chairperson said. For industrial category, the increase per unit is in the range of 54 paise to 65 paise per unit and for commercial sector, the proposed increase is in the range of 57 paise to 72 paise per unit. For the agriculture sector, the proposed tariff has been increased by 48 paise per unit to 506 paise a unit. Notably, farmers are provided free power by the

government. The state government has pegged the subsidy burden on account of free power at Rs 6,000 crore for 2017-18. For the bulk supply, the power rate has been increased in the range of 10.52 per cent to 11.08 per cent. The fixed charges will be in the range of Rs 20 per kW to Rs 60 kVA for domestic supply, Rs 50 to 100 per kVA for commercial supply and Rs 85 to 295 per kVA for industrial category including bulk supply, as per the order. The hike in power tariff was announced after a gap of three years, said the PSERC chairperson. For industrial category, the increase per unit is in the range of 54 paise to 65 paise per unit and for commercial sector, the proposed increase is in the range of 57 paise to 72 paise per unit. For the agriculture sector, the proposed tariff has been increased by 48 paise per unit to 506 paise a unit. Notably, farmers are provided free power by the government. The state government has pegged the subsidy burden on account of free power at Rs 6,000 crore for 2017-18.

kVA for industrial category including bulk supply, as per the order. The hike in power tariff was announced after a gap of three years, said the PSERC chairperson. Addressing media persons here, Sidhu said the consolidated gap of Punjab State Power Corporation Limited was worked out at Rs 2,522.62 crore against power utility's proposal of Rs 11,575.53 crore. "This new tariff is fixed for one year 2017-18," said the chairperson. However, expenditure of three years has been finalized and annual revenue requirement (ARR) has also been fixed but not tariff for next two years, she added. The net revenue requirement for PSPCL has been worked out at Rs 28,910.35 crore, Rs 30,241.30 crore and Rs 31,739.58 crore for 2017-18, 2018-19 and 2019-20 respectively. It was also for the first time that the regulator came out with two-part tariff for all categories except for the agriculture sector. It was also for the first time that the regulator came out with two-part tariff for all categories except for the agriculture sector. The two part tariff structure envisages a fixed charge and a variable charge which has been adopted by almost all the states in line with national tariff policy, she said. The power subsidy burden for the year 2017-18 has been estimated at Rs 10,970 crore including free power to farmers, subsidized power to SC/BC and arrears of Rs 2,800 crore However, the subsidy burden does not include the subsidised power at the rate of Rs 5 per unit to industrial category which has been announced by Congress led government in Punjab. Meanwhile, former deputy chief minister and Shiromani Akali Dal (SAD) president Sukhbir Singh Badal demanded immediate withdrawal of the "draconian" power tariff hike. In a statement here, the former deputy CM said chief minister Amarinder Singh had made an announcement one month after assuming power that all consumers would be supplied power at the rate of Rs 5 per unit. AAP MLA and leader of opposition in Punjab assembly Sukhpal Khaira while condemned the hike in power tariff said it will further dd to the woes of common people who are already facing "steep" inflation. "We demand its rollback," he said.

M&M and EESL Collaborate for LED Replacement Across Mahindra's Facilities
Mahindra & Mahindra has partnered Energy Efficiency Services Limited (EESL) and invested Rs 16 crore for a LED replacement programme with energy efficient alternatives across M&M's manufacturing facilities as part of its sustainability drive as well as to bring down operation costs. EESL, the company under the ministry of power that aims to implement world's largest energy efficient portfolio in the country will be providing technical assistance, cost efficient procurement and project
management services for the project. "This partnership marks a very significant step towards promoting energy efficient lifestyle among corporates and large facilities in India," MD of EESL, Saurabh Kumar said in a release. While this will be EESL's first private sector collaboration for promoting energy efficient appliances in a working space, Kumar said they look forward to "more such collaborations so that organisations adopt EE appliances that will help them in reducing
operational cost through energy savings." Mahindra has also encouraged its suppliers, dealer partners and employees to emulate its move to reduce carbon emission. "There is a mindset that sustainability comes at a price. But sustainability actually makes money for you, everything that we have done with EESL has a financial payback for us," Pawan Goenka, ,MD, Mahindra & Mahindra said. "Our interest in sustainability is not simply to be a good corporate citizen , it is a part of business strategy as there are many businesses that are emerging out of this sustainability drive, for example our solar and bio-CNG businesses." The payback for this investment is expected to be one year, Goenka said. The automaker is also doing pilot projects with EESL for the motors used across its facilities as well as for air conditioners to replace them with more energy efficient alternatives and has set aside Rs 7 crore to replace motors as well as Rs 6 crore to replace air conditioners. The spending is part of Mahindra's commitment to invest $10 per ton of carbon emitted in technologies to reduce its carbon footprint and it currently has pegged its expenditure on bringing down its carbon emission at Rs 30 crore.
Soon, Like Mobile Number You May Also Port Your Power Supplier The government plans to give electricity consumers the freedom to choose the supplier by enacting a new law that will bring the long-awaited system similar to mobile number portability. It plans to table the necessary bill in the winter session of Parliament that begins in the third week of November, although it has faced resistance from states. Several state distribution companies are keen to protect their monopolistic position, without which consumers can shift to the suppliers they trust. The new bill will usher in competition, which analysts say will attract investors apart from giving consumers reliable supply at affordable rates and reducing losses. "It will provide the biggest platform for investors to get into Indian utility business which has 250 million customers providing choice and facilities to customers. Clear road maps were drawn on its implementation in 2014. Heartening to note government is pushing a transformational legislation," Sambitosh Mohapatra ..

This will also improve the financial health of the sector, he said. "To ensure Uday-related targets are achieved on the ground, segregation of content and wires along with competition in content business is necessary." Officials said that to address the concerns of the states, the bill may not impose timelines for implementation. The states may, however, be asked to notify their plans for implementation of the reform for electricity connection portability in the next 3-5 years, he said. The proposal, to separate electricity supply and network maintenance services and introduce multiple licensees for a single area by amending the Electricity Act 2003, has been in works for last many years. The proposal is similar to mobile number portability where consumers can switch to a telecom operator of their choice. Currently, the power distribution utilities are responsible for operating and maintaining distribution system in their licensed areas.
"Though the proposal will benefit consumers by bringing competition in the retail electricity sector, it has been resisted by the states. So the government is considering introducing a lenient version of the bill with no timelines imposed on states," a government official said. Once the bill is enacted, the central government, however, may ask states to notify their plans to implement the law, he told on the condition of anonymity. Segregation of the network maintenance and electricity distribution businesses is seen as an important reform for improvement in quality of electricity supply services. Earlier the government had planned specific timelines for opening up the retail electricity sector. These included reaching milestones like implementation of advanced metering system, separate accounts and employees of distribution companies, ownership separation and introduction of multiple and de-regulating tariffs for large industrial consumers. ||www.electricalmirror.net||

How Danish Company Vestas Built a Rs 500 crore Blade Factory Near Ahmedabad in a Record 15 Months
Bert Nordberg, chairman of Danish wind turbine maker Vestas, had a brief meeting with Prime Minister Narendra Modi in New Delhi. Nordberg gave a commitment to the PM that the company was willing to bring in substantial foreign direct investment (FDI) into India for setting up a wind turbine blade manufacturing factory. Within 10 days of the meeting, the Vestas board approved its India plan, gave its nod to a factory location 30 km west of Ahmedabad and then quickly brought one of its senior executives of Indian origin, Madhava Krishna Pokala, from the sleepy town of Ringkobing in Denmark to oversee the process of setting it up. Next up were a MoU with the government of Gujarat, procurement of 20 permits and finally investing €70 million (roughly Rs 500 crore) to establish a greenfield manufacturing unit in a 36-acre plot off the Ahmedabad-Rajkot highway. In 15 months, the factory began blade production, making it a rare example of a fast-tracked FDI investment into India. “Consent to establish is a critical clearance requirement to begin construction. We received it in 22 days as against the usual 60. Also, power at the factory site was made available in six months rather than the usual 18 months due to effective influence of the Invest India cell of the Government of India,” Clive Turton, president (Asia Pacific), Vertas said. The Gujarat factory that has a capacity of 600 MW produces 900 blades a year; three blades are needed for one wind turbine of 2 MW, producing enough electricity for as many as 35 villages. “If needed, we can expand the factory and double its production. But that will depend on the work we receive,” says Amar Variawa, the company’s director of marketing and public affairs. Wind energy installation in India rose from 2.3 GW
22 NOVEMBER 2017 ||ELECTRICAL MIR R OR
in 2014-15 to 3.4 GW in 2015-16 before peaking at 5.4 GW in 2016-17 (1 GW = 1,000 MW). But till August this fiscal year, wind energy installation was barely 0.35 GW mainly on account of the government’s change of policies and ending of subsidies, forcing equipment manufacturers to pile up inventories for better days. Vestas still seems to be bullish on its India story. Its research and development centre in Chennai is already the largest outside of Denmark. Chennai also houses its nacelle and hub factory. Turton says, “The Indian government has set an ambitious target of 175 GW for renewable energy installation by 2022 out of which 60 GW is wind. The massive volume has attracted both domestic and global players to wind energy.” Mahindra Susten to build India's 1st battery-backed solar project in Andaman Mahindra Susten, a part of the Mahindra & Mahindra group, is close to setting up India's first battery-backed solar power project of utility scale in the Andaman and Nicobar islands. The company has emerged lowest bidder in a tender invited by state run-NLC (formerly Neyveli Lignite Corporation), beating Adani Group, Hero Future Energies, among others with a bid of Rs 288 crore. As a part of a government initiative to encourage battery-backed solar power project, two other public sector companies — Solar Energy Corporation in India and NTPC — were to award similar projects but have scrapped it after inviting bids. "Current energy requirement in Andaman and Nicobar is primarily met by diesel generator set and the cost of generation is as high as over Rs 20 a unit. This is an environment friendly option and cheaper too," Basant Jain, chief executive officer, Mahindra
Susten, confirmed. He said that the project will receive agrant of Rs 100 crore from the government, which would lower the effective tariff to Rs 8 a unit. "Even without the grant, the cost of power will not be more than Rs 12 a unit, which is cheaper than power from diesel-run unit, and would still meet internal rate of return targets," he said. Mahindra Susten would be doing the engineering, procurement and construction work for the project which is scheduled to be commissioned in 18 months from the beginning of the projects. Industry sources said that NLC opened the bids in August but has been delaying awarding it since it may be exploring other options like running power on liquified natural gas. An email sent to NLC on this issue remained unanswered. India's solar-power capacity has grown exponentially to around 14 gigawatts (GW) and the government has set an ambitious target of 100 GW by 2020, but storage has been a missing link thus far and the government is now acknowledging the need for it. Therefore, the government wants the industry to set up battery-manufacturing units in India as a sharp decline in prices of batteries between 2010 and 2017 has made battery-backed solar power more viable. "We are also considering technology partnership with foreign solar storage technology companies to sharpen our capability further and offer this service in other geographies. While solar with storage tenders in India will come up in a big way going ahead, there are some very big projects coming up in the Middle East and the US." Mahindra Susten is a part of Mahindra Partners which is the $1 billion private equity division of the $19 billion-Mahindra group, led by Anand Mahindra. The group has identified solar power as a key growth area to tap the potential in the country. India has huge solar power potential but this form of power is inherently intermittent and subject to fluctuations. Around the world, countries balance this with gas-based or hydropower to ensure continuous power supply but India does not have much gas, and hydropowerproject development in the country has been slow. Battery storage is a good back-up option but so far, the high cost of storage was a discouraging factor for the price-sensitive market in India. But the fall in prices of battery is making these projects more attractive and luring companies like Mahindra Susten and global majors like Wartsila to enter the space.

High GST Rate of 28% on Electrical Wires and Cables Adversely Impacting the Indian Electrical Industry and Setting Inflationary Trend in the Economy
• A major setback for the domestic industry, which is reeling under low domestic demand and surge in imports Indian Electrical and Electronics Manufacturers’ Association (IEEMA) made a representation to the Government of India and the GST Council regarding high GST rates on Electrical Wires and Cables (HSN 8544). Presently, Electrical Wires and Cables are attracting a GST rate of 28%, and IEEMA has requested the government to get these items reclassified under 18% GST. GST rate of 28% are very high as compared to previous tax incidence of about 14%. This impact of high GST rate will lead to1. Fuel Inflation: By keeping the GST rate of 28% on Electrical Wires and Cables (HSN 8544), the product has become costlier, fueling inflation, leading to high tax incidents and adversely impacting the domestic industry. This goes against the government’s commitment that GST would not be inflationary and lead to reduction in tax incidence, at the same time, promoting the domestic industry. Since both public and private power utilities and the end users, constituting approximately 70% of the usage of Electrical Wire and Cables, manufactured in a year, do not get any Input Tax Credit; therefore, the cost of transmission
and distribution of power increases and sets an inflationary trend in the economy. 2. Increase in Working Capital Requirement: Almost all the raw materials used for manufacturing of Electrical Wires and Cables, are taxed at 18% under GST Regime. Hence, this huge gap between the rate of tax applicable on inputs and outputs is resulting in an effective increase of 14% in working capital requirement by the manufacturers of Electrical Wire and Cables, leading to an increase in cost of manufacturing. This will further have an adverse impact on the industry, which is already in a bad shape due to low domestic demand and surge in imports and also increase the Project Cost for the utilities. Mr. Shreegopal Kabra, President, IEEMA stated, “One of the significant agendas of the Government of India is to provide electricity 24X7 to all and ensuring last mile connectivity through rural electrification. High rates of electrical products dissuades use of essential electrical equipment. A fair rate of 18%
would encourage the use of these products in the rural areas and positively boost the rural electrification agenda of the Government of India”. IEEMA Director General, Mr. Sunil Misra, said “As electricity is kept out of GST, no input credit of GST paid on electrical products is available to electricity companies. This means a higher rate of GST is incurred on inputs resulting in higher cost of final product. Since the electrical industry supplies equipment for infrastructure development of the country, IEEMA feels that 18% rate of GST should be imposed on all products used for Generation, Transmission, Distribution and Consumption of Power.” “Electrical Wires and Cables are mainly in the nature of the Capital Goods and constitute about 3 – 4% of the project cost, in every project, whether it’s an infrastructure, power, housing, industrial or a Commercial project. Electrical Wires and Cables are a necessity for all sectors of economy, and certainly needs to be charged at a lower rate of tax and not at 28%, which is a rate reserved for luxury items and items of prohibitory nature.” quoted Mr. Rakesh Amol, Chairman IEEMA Wire & Cables Division.

Cover Story
Renewable Energy Prospects in India
Market opportunity
The solar industry's structure will rapidly evolve as solar reaches grid parity with conventional power between 2016 and 2008. This growth story has two chapters: the seed phase, where independent solar power producers receive govt support, followed by the growth phase, where rising demand and favorable economics lead to rapid industry growth, attracting larger utilities.
India presents a reliable, fast growing, well-diversified, and profitable market opportunity for renewable energy. The imperative to add substantial new generation capacity to meet social and economic needs is helping India reshape its energy mix towards renewables quicker than other regions. Power utilities and retail consumers alike are contracting with large-scale renewable energy suppliers to meet their basic energy needs. India’s per capita energy consumption is very low, in fact, it is about one-third of the world’s average and below other comparable developing countries. The growth picked up in recent years rising from 612 kWh to 1,010 kWh over last decade (2005-); a growth of 5.1% pa. Rural electrification and provision of 24X7 power supply is a key priority for the govt. Based on available statistics 19,706 villages lack access (2015), and a large proportion of households (33%) do not own an electricity connection (2010 Census). In most states rural power supply is intermittent and of poor quality. New generation capacity must be built, and given the affordability and concerns of marginal consumers, renewables with minimal cost inflation suit it best. Urban centres, too, have grown rapidly and India, which is relatively less urbanised with only 31% of population in cities, is moving in the direction of other developing nations such as China (50% urban population) and Brazil (87%). Urban areas are significantly more energy intensive and constitute a key driver of demand growth.
Policy support
Energy security is a prominent policy concern. Primary fuels are India’s single largest import, accounting for 37-40% (2013-15) of total imports and periods of high commodity prices have resulted in constrained supplies, budgetary deficits, and fueled inflation. Climate change is a key consideration too with coal responsible for 76% of electricity produced. The govt’s drive to build 175 GW of RE by 2022 will help achieve energy security and reform energy mix. The policy proposes to use RPO and RGO targets to develop this, and regulators are seen to take steps to improve enforcement. The govt has set in place a robust procurement model in the form of auctions and standard bidding documents (RFQ, RFP, PPA) to facilitate a quick, harmonized, and transparent bidding process for solar power development.
Public interest and local development
Public opinion has been supportive of sustainable energy in India, and this has helped states maintain a positive and stable policy environment over the years. On similar lines, a number of private companies are setting up renewable energy projects for their own use, or have committed to source 100% of their consumption from green sources. State-owned organizations are tasked with establishing 10 GW solar projects. The courts too have taken a positive view. The Supreme Court of India recently (May’15) ruled that renewable obligations are in larger public interest and can be imposed on captive users and open access consumers. Renewable energy projects are often
C
Over Story Renewable Energy
located in distant and remote areas and in some cases in arid lands. Employment, even in limited numbers, improves social and economic prospects of the region. Decentralized energy initiatives such as roof-top solar power plant and solar-powered agriculture pump sets offer scope to generate electricity at the tail end of the grid, and potentially where net metering policies are in place thus offering a modest source of income.
Economics and profitability
Renewable energy build, as described earlier, is increasingly competitive with electricity from mainstream fossil fuels such as coal and natural gas. This is driven both by a variety of global factors (e.g., technology, module prices, and optimization) and local factors (competition in capital goods and EPC, financial engineering, new entrants, and captive users). The competition is a strong force. India has about 20 wind turbine manufacturers with an annual production capacity of 11 GW. A majority of these (Suzlon, WindWorld, Inox Wind, Regen Powertech, Gamesa) offer a complete turnkey solution whilst others (GE and Vestas) focus on products. The supply of solar modules is predominantly from imports whilst the balance of plant and inverters are locally sourced. The solar EPC market is also very heavily contested offering competitive pricing and turnkey solutions to developers. The state electricity regulators maintain a provision of post-tax return of 14-16% in tariff determination for relevant renewable energy technologies such as wind, biomass, waste-to-energy or small hydro. Where auctions are held, such as in solar, project developers make their judgement on return expectations, and winning bids in general have been in the low-teens.
Resource base
A number of studies suggest that India’s renewable energy resource base is several times higher than the earlier estimates. A Berkeley lab study reckons India’s wind potential to range between 2,006 GW and 3,121 GW (for different mast height and site conditions) which is several times the earlier official resource assessment of 48.5 GW. Furthermore, regulators in some states are offering differentiated FIT to tap low wind zones. The govt is exploring options to incentivize repowering. All these steps expand the market potential for renewable energy. Likewise, solar energy potential estimated by the National Institute of Solar Energy is about 749 GW. This is spread across a wider number of states, viz. Rajasthan (142 GW), Jammu and Kashmir (111 GW), Maharashtra (64 GW), Madhya Pradesh (61 GW), Andhra Pradesh (38 GW) and Gujarat (35 GW). Offshore wind is another prospect. It is novel elsewhere too (global offshore wind is 8.7 GW) but the industry expects it to grow (180 GW by 2035, IEA forecasts). India seeks to tap its long coastline of 7,600 km for offshore wind, but current candidates are the western coast of Gujarat and southern tip from Rameswaram to Kanyakumari in Tamil Nadu. The govt has approved a National Offshore Wind Energy Policy which tasks MNRE and NIWE to develop the potential in India’s exclusive economic zone. A pilot project of 100 MW is to be set up by select state-owned companies and Suzlon announced a 300 MW offshore wind project in Gujarat. Global players such as Areva, Siemens and GE have voiced plans to explore India’s offshore wind power opportunity. A considerable preparatory work remains; to study the wind patterns and sea bed, maritime activities, logistics support, and sea-seismic studies.
Business models
As discussed earlier, India’s power market offers renewable energy generators a wide range of options for sale of power feed-in tariffs, renewable energy certificates, captive and open access sales. This means a wide range of investors can be pursued who then can structure sale contracts that are best suited to their risk-return profile. The regulatory terms for open access (costs of transmission charges, banking, and cross-subsidy recovery) are pro-renewables and offer a strong cost advantage to benefit generators and buyers of renewable energy. The revised grid arrangements for forecasting and scheduling and levy of 34 NOVEMBER 2017 ||ELECTRICAL MIR R OR
imbalance cost provide a clear and realistic path for the development of the renewable industry.
Industry response
The govt’s market outreach program the first Renewable Energy Global Investors Meet and Expo (RE Invest 2015) attracted wide interest. Domestic private investors expressed interest to develop a total of 190 GW of renewable energy projects, while the state-owned entities committed to develop 18 GW and overseas investors committed to set-up 58 GW. On the manufacturing front, 41 GW of renewable OEM facilities have been proposed. Financial institutions including banks expressed intent to fund renewable energy projects of 72 GW. The govt has now initiated consultations with state agencies and the private sector to help translate these active investments. This promises to be an exciting and profitable time to invest in India’s renewable energy story. Crucial Solar As recently as 2009, the JNNSM'S target to reach 20 GW by 2022 appeared overly ambitious. Today, few doubt that the JNNSM will not only meet its target, but also exceed it. Based on our estimates, the combination of electricity demand growth, fossil fuel cost and availability challenges, and supportive environmental regulations could increase solar power capacity to more than 50 GW by 2022. The solar industry's structure will rapidly evolve as solar reaches grid parity with conventional power between 2016 and 2008. This growth story has two chapters: the seed phase, where independent solar power producers receive govt support, followed by the growth phase, where rising demand and favorable economics lead to rapid industry growth, attracting larger utilities. In the seed phase, before solar power reaches grid parity, the subsidy-driven market will have projects awarded through competitive bidding. Implementation challenges and regulations, including renewable purchase obligations (RPO’s), renewable energy certificates (REC’s), and net metering, will ease in this phase, and investor confidence will rise. These factors will combine to bring on the subsequent growth phase, when the sector more than triples in size. We expect a shift in demand patterns and in the way industry players view Solar’s feasibility in the period 2016-18. Solar will be seen more as a viable energy source, not just as an alternative to other renewable sources but also to a significant proportion of conventional grid power. The testing and refinement of off-grid and rooftop solar models in the seed phase will help lead to the explosive growth of this segment in the growth phase.
Seed Phase: Global prices for PV modules are dropping, reducing the overall
cost of generating solar power. In India, this led to a steep decline in the winning bids for JNNSM projects. With average prices of 15 to17 cents per kwh, solar costs in India are already among the world's lowest. Given overcapacity in the module industry, prices will likely continue falling over the next four years before leveling off. By 2016, the cost of solar power could be as much as 15% lower than that of the most expensive grid-connected conventional energy suppliers. The capacity of those suppliers alone, nearly 8 GW in conventional terms, corresponds to solar equivalent generation capacity potential of 25-30 GW. Due to implementation challenges, however, it's unlikely that all of this potential will be realized by ||www.electricalmirror.net||

2016. The competitive bidding model, which has been successful, will likely continue through the seed phase. The JNNSM will be crucial to the sector during this phase, as will state-run programs such as those in Gujarat and Rajasthan. In all, we expect 12-14 GW of capacity to be added during the seed phase - almost entirely in the form of grid-connected utilities. The total capacity added in the off-grid space during this phase may be less than 1 GW. However, heading into the growth phase, as solar power becomes more competitive than other forms of alternative energy, we expect off-grid capacity to rise exponentially. Grid parity will be an inflection point, leading to two major shifts in the solar market. First, thanks to favorable project economics, grid-connected capacity will rise at a much faster rate than before, and second, regulations and policy measures will be refined to promote off-grid generation.
Growth Phase: The market will see a significant change after 2016. Lower
solar costs combined with rising prices of grid power will convince off takers (including discoms, private firms using open access, and firms putting up their own captive capacity) that solar power is economically viable. This shift will signal the start of the growth phase, during which grid-connected solar capacity will rise rapid|ytoabout35 GW by 2020 as developers build capacity to meet both RPO requirements and demand from off takers seeking cost-efficient alternatives to conventional power. he bid-driven system will need to change, as technology and cost structures stabilize with the likely introduction of feed-in tariffs. The frameworks for RPOS and RECS frameworks could change as well; however, solar-specific RPOS are likely to remain for the next decade and potentially see a steady rise to a national average of 3%. The premium for solar RECS is likely to reduce, while RECS may also tend towards a single structure across renewable energy sources after grid parity is achieved.
power an economically viable alternative, particularly for urban and semi-urban consumers. Distributed generation in rural areas and support for latent urban demand has the potential to reach 4 GW by 2020 and increase rapidly to more than 10 GW over the next three to four years. The Indian rooftop and distributed generation market will evolve differently from the rest of the world, largely because the typical Indian rooftop and the typical distributed generation consumer pose unique challenges that require innovative solutions. Examples of such challenges include the typical size, infra available, and security and theft issues. Once the domestic business model is in place, however, the potential is huge. We expect a slow initial build-up of demand, and strong acceleration thereafter.
Key Barriers
The main disadvantage of solar energy is its unavailability. The weather conditions are major factor on availability of solar radiation. So, we can’t say in a particular time the energy from solar will be available to us or not. Land is also a secret reserve in India and as per capital availability is low. Large land area is required, which sometimes is not feasible. The amount of land required for utility-scale solar power plants is currently approximately 1 sq. km for every 20-60MW generation. 100 GW of solar would mean about 10.5% share for solar power in total generation of power in India. Such large share of intermittent sources requires huge investments in the power grid infrastructure for transmission smart supply and demand management. To achieve a capacity of 60 GW for utility scale projects by 2022, there would be a requirement of about $40 billion. The govt currently expects a big share of this to come from international sources. But an international fund for solar projects in India is very less. Storage problem is also very serious. Suppose if the demand of power is not so high then the electricity produced by the solar plant will have to be stored somewhere to supply when demanded. This increases the cost of the project.
High cost of financing: renewable energy technologies have high capital costs
but very low operating costs spread over 25-30 years. However, the cost of finance (currently ranging from 12–14%) forms a significant component of the power tariff from these sources. Reduction in interest rates would reduce tariffs and improve the competitive edge of the technology. Financing costs depends on the risk perceived by funding institutions and higher perceived risks result in more stringent financial conditions. The relatively high cost and low availability of debt in India has significantly increased the cost of renewable energy projects which is a major barrier to the expansion of the renewable sector. Lack of enforcement of RPOs: The RPO is the biggest driver for the uptake of renewable energy by state utilities and captive users (obligated entities). The RPO regime is an instrument for stimulating renewable energy investments. However, lack of RPO enforcement has led to concerns about the final purchase of renewable power. The state discoms will have to start taking RPOs seriously and state regulatory authorities would have to hold the discoms responsible and penalize them for failing to comply on purchase obligations. Instead of forcing defaulters to buy RECs (Renewable Energy Certificates) to cover shortfall in power purchase, states are allowing the obligated entities (such as DISCOMs and captive consumers) to ‘carry forward’ deficits to the next financial year. There also needs to be harmonization of the state-level RPO targets with the national targets.
Off taker risk: The creditworthiness of the distribution companies is a critical issue
The JNNSM's target to reach 20 GW by 2022 once appeared overly ambitious. Today, few doubt it will meet that target. Meanwhile, the off-grid and rooftop segments will grow exponentially as price parity with consumer tariffs makes solar 36 NOVEMBER 2017 ||ELECTRICAL MIR R OR
and plays a key role in determining the bankability of a PPA (Power Purchase Agreement). Very few discoms are in good financial health. When discoms have poor financial health, the risk of off-taker default and delayed payments is high. Weak financials of discoms will keep them from meeting commitments and affects the effectiveness of instruments that have been put in place for deployment of renewables. Recently the Electricity Regulatory Commission of Uttarakhand imposed a penalty on its discom for not complying with its renewable power obligation (RPO) target. Such actions are important for proper functioning the renewables sector. ||www.electricalmirror.net||

Over Story Renewable Energy
Intermittency: Renewable energy is as an intermittent
source of electricity. Characteristics of renewable power make it variable (natural variation in generation; eg. wind peaking during monsoon and reducing in availability in other seasons) and affect the degree of its predictability (e.g. sudden drop in wind power). Renewables can be integrated into the grid by taking measures like renewable energy generation forecasting; coordinated project development; grid planning and grid strengthening; reducing the variability and uncertainty of RE generation through aggregation over broader geographic regions; creating flexible capacity, spinning reserves and ancillary services market; and properly defining RE grid integration standards and regulations.
Inadequate evacuation infrastructure: Lack of
adequate evacuation facilities has led to scaling back the commissioning and partial commissioning of new generation and the reduction of generation during peak periods. Banks and financial institutions are more cautious lending to renewable energy projects given the poor state of the evacuation networks. Access to grid access is a critical challenge as renewable resources are often located far away from the consumer market. Though states are required to provide the infrastructure for evacuation of power from RE projects, in practice it is the RE developer who has to provide for such infrastructure. This has an impact on the cost of the project. Even where states provide evacuation infrastructure, such infrastructure is inadequate. Utilities have been reluctant to develop transmission lines for them due to the low utilisation of renewables during the lean period and due to delays in securing budget approvals from the govt.
Permits and Land acquisition: There is a need to
streamline, accelerate, and standardize the acquisition of permits, clearances, and other administrative hurdles that the developer must cross. These relate particularly to land acquisition and environmental permitting. Acquisition of land is a critical aspect for infrastructure development and the approval processes and inability of the state govts to provide an effective single-window clearance to developers has caused considerable challenges. Lack of coordination among key organization like revenue department, state pollution control board, grid operators has led to time and cost overruns resulting in high transaction costs. A robust system setting a time bound target for getting all approvals without having to follow up with different state govt departments needs to be put in place for renewable energy developers.
Financing for off grid power: There have been
a number of barriers preventing scaling up of the subsidy mechanism for encouraging investment in the off-grid energy sector. There is a large amount of 38 NOVEMBER 2017 ||ELECTRICAL MIR R OR
paperwork and several layers of bureaucracy before subsidies are approved. Despite these subsidies are often delayed or not disbursed at all. Such delays result in liquidity constraints for companies placing pressure on the day-to-day operations of their business. There are also many challenges in loans available to off grid companies. Companies can face interest rates of 13-18% in the domestic market which are very high and foreign loans can also only be used on a project basis according to regulations. Most banks are not willing to lend even at higher interest rates because sizes of loans are considered too small.
Three Elements to Winning in Solar
Execution: Given the substantial front-end costs of
solar projects, delays can wreak havoc on profitability. Even under the most suitable conditions, managing power projects in India is tough—projects are often slowed by infrastructure issues and unreliable local vendors. In addition, stakeholder management at the national, state, and local levels often stands in the way of ensuring efficient project execution and sustained operation. Therefore, building a team of talented project managers and experienced troubleshooters will be crucial.
Financing: Innovative means of financing will create win-win situations for all stakeholders and drive significant upfront value for project developers. Differentiated models could include teaming with technology providers from low-cost financing countries - japan, for eg - or with consumers seeking sustainability benefits ortax credits. A pool of low-cost project equity developed from retailor other cost sources can add up to a distinct advantage. Localization: Local design and engineering will
play a major role in India's solar market. Inverter and balance-of-system designs that incorporate local requirements and eliminate unnecessary elements that are geared more toward global markets can generate significant benefits. Eventually, global players will see the benefits of manufacturing locally and specifically for the Indian market. Competition from local players could further drive down systems costs.
TERI’s National Road Map or ShortMedium-Long term plan
a roadmap is suggested for effective planning and the way ahead for renewables. The MNRE has a vision for renewable energy, to be a significant source in furtherance of the national aim of energy security and independence. A vision is essential as it serves as the uniting component that all stakeholders can refer to. The vision is realistic but still has the provision of novel and new ideas that add real value and push the set boundaries. Once the vision is well established, it is necessary to translate it into more specific objectives and targets, for the different sectors in which the local authority intends to take action.
Short Term Plan: By 2020
Deployment of renewable energy for meeting energy needs in rural areas: Target 1 lakh family type biogas plants per year. Target biomass gasifiers for village energy supply in 25 villages per year. Installation of decentralized SPV systems (a. 50,000 solar lighting systems and solar pumps per year b. 20,000 solar irrigation pumps can be targeted for installation in the current year). Target installation of 500 Micro Hydel Projects/watermills with capacity of approximately 4 MW each year. Installation of 20 projects utilizing Aero generators and SPV-Wind hybrid systems with a cumulative capacity of 20 kW per year. Disbursement of around 2 lakh Improved cook stoves per year. Deployment of renewable energy to supplement energy needs in urban areas: Installation of solar thermal systems in urban households/buildings covering approximately 5 lakh m2 area. 50 MW of Rooftop SPV grid connected systems per year. Disbursement of Solar cookers 25,000 solar cookers per year. Deployment of renewable energy to supplement energy needs in industrial and commercial establishments: Generation of Energy from Industrial waste of 10 MWeq. Installation of 50 gasifiers for decentralized power generation in rice mills and other industries. 80 MWeq of biomass based cogeneration in other industries excluding bagasse.
Medium Term Plan: By 2030
Promote initiatives for increasing deployment of renewables: Set up Wind energy mission. Promote Ultra mega solar projects and solar projects for canals. Integrate ongoing programs such as rooftop, solar cities with smart city program. Set up national Bio energy mission. Develop resource base for enhancing the potential of renewable energy sources: Reassessment of wind potential at 100 m hub height. Assessment of solar potential. Assessment of off-shore wind potential and prepare a policy on off-shore wind power. Revaluate DNI data for Solar thermal technologies that can become the basis for project design and financialviability calculations for all states in India. Continuing improvements in regulatory and policy initiatives to promote renewable energy technologies: Address issues relating to tariff for renewable energy technology based power projects, renewable purchase obligations and measures like renewable energy certificates and other market based mechanisms, market and grid connectivity issues, inter-state exchange of renewable energy. Pursue the compliance of renewable energy purchase obligations with regulatory authorities & states. Setting up transmission systems required primarily for renewable energy projects. Assistance may also be required for Solar Parks. Development of strong monitoring and ||www.electricalmirror.net||
evaluation frameworks for the various schemes and programs. More efficient monitoring and verification is possible through automatic data acquisition. Developing and deploying appropriate financial instruments: There is need for continued fiscal and subsidy support. Banking and financing community need to be engaged to support the renewable energy sector. Exploration of alternate financial instruments such as: Products like Risk Guarantee Fund that will address the technology risks, especially for solar. Availability of debt at a lower cost (both for grid and off-grid projects) through channels such as external borrowing or tax rebates, especially for solar technologies. Enhancing the term lending period particularly for technologies such as solar.
Other interventions: Promote funding of innovative
clean energy projects through the National Clean Energy Fund (NCEF). Promote effective systems for monitoring performance of programs/ installed projects. Promote indigenous industry in manufacturing of renewable energy. Develop large
scale solar manufacturing in India (transforming India into a global solar manufacturing hub). Human Resource Development: Establish R&D facilities within academia, research institutions, industry, government and private entities to guide technology development. Develop training programs for specific and highly specialized areas related to science & technology, and management. Training for financial sector on the issues relating to project financing of renewable energy projects. Small and medium scale manufacturing, industrial undertakings, services and business enterprises (SME) on development of convenient technology packages for different SME groups, technological solution awareness, best practices for renewable energy use, strengthening outreach of renewable energy technologies to consumers etc.
Long Term Plan: 2047: Incubating technologies
with high future potential Promote and target a hydrogen economy development. R&D in Hydrogen production, storage and distribution has to be strengthened. Government should announce
pilot projects with storage technologies to have projects on the ground to showcase performance of the technology. Initiate move to electrify automotive transportation or develop electric vehicles plug-in hybrids. Adopt nationwide charging of electric cars from solar panels on roofs and solar-powered electric vehicle charging stations around the country. These recharging connections could be deployed at highlyconcentrated areas including shopping malls, motels, restaurants, and public places where vehicles are usually parked for extended periods. Aggressively invest in a smart, two-way grid and micro-grid. Smart meters as well as reliable networks can accommodate the two-way flow of electricity. Such networks can be resilient enough to avoid blackouts and also accommodate the advanced power generation technologies of the future. Develop large-scale solar manufacturing in India to transform India into a global solar manufacturing hub. Promote and establish utility-scale Renewable Energy Zones (REZs) utilizing solar and wind generation.

India Wires and Cables Market Outlook Driven by Government Initiatives and Innovations
K
ey facts
Rapid economic growth. India's economy is capable of absorbing $50 billion in FDI per year. India's economy will grow 5-fold in the next 20 years (McKinsey). India's infra financing requirements and the new manufacturing policy will open up US$ 1 Trillion opportunities for global investors over the next 5 years. Automobile industry, the 7th largest in the world, has currently been estimated to have a turnover of US$ 73 billion, accounting for 6% of its GDP. It is expected to record a turnover of US$ 145 billion by 2017. The Indian real estate market size is expected to touch US $180 billion by 2020 (CREDAI). The main customers for the wire & cable industry are the automotive, telecom and construction industries. In the past few years, these 3 have witnessed a rapid expansion and have led to an annual growth of about 25% in India. GoI has begun to focus primarily on PPPs with major infra projects. With an investment need of about $450 billion until 2012, the infra construction is the growth engine for the construction industry, especially for the development of the transport sector. As per the details provided in the Automotive Mission Plan 2006-2016, the Indian govt is geared up to double the automobile industry's contribution to the country's GDP and furthermore intends to create 25 million new jobs in the industry. The telecom market in India is the 3rd largest in the world and it is the fastest growing. This growth is being witnessed in the wireless and telephony sectors. Furthermore, in the Internet sector, the govt is making endeavors to provide the rural regions of India with broadband connections.

Globally, the wire & cable sector has been dominated by China, USA, Japan, UK and South Korea, where China is the top manufacturer and exporter of the sector in the financial year 2013-14. India, with a market size of approximately USD 3.39 billion in FY 2013-14, holds the 6 largest potential market for the wire & cable sector worldwide after China, USA, Azerbaijan, Turkey and Lithuania. The wire & cable sector in India, being a net importer sector, is dependent on imports from China, UAE, Russia and Japan. The wire & cable sector is organized in nature due to the availability of limited no of players in the market, which controls the competition in the market. The favorable factors such as the recovery in India’s economy and the planning of the govt to increase the development activities in the area of power, telecommunication and real estate, may accelerate the growth rate in the sector of wire & cable.
The wire & cable sector is classified as per the requirement of the end user, such as power cable, wire & cable for electrical equipment, winding wire, exposed wire, communication cable and wire & cable accessories. Presently, global market of insulated wire & cable consists of electric conductors up to 1000 volts with 70.60% of the global demand and the remaining proportion of 29.40% is comprised co-axial cable and co-axial electric conductor, electrical conductors more than 1000 volts, insulated winding wire of copper, optical fibre cables and other insulated winding wire.
Market trends
The wires & cables industry in India has come a long way, growing from being a small industry to a very large one, over the past decade. Although the industry comes with a lot of technical and quality nuances, it is mostly volume driven. Over the last 20 years, the industry has shifted from being an unorganized sector to an organized one, still 35% of the industry continues to be a part of the unorganized sector. Wires & cables play an indispensable role in today’s digitally advanced life and find extensive usage across a number of applications in several industries. The extensive usage and applications of wires & cables across various industries will put the wires & cables industry on the right path for the future. The trend in the market keeps changing these days. But it is also believed that govt has made the right move in the past few months when it comes to investment. Govt on the whole needs to get private investments moving by reducing the interest rates. This will help in kick starting the economy. That being mentioned, govt needs to start focusing a little bit on incentives. ||www.electricalmirror.net||

As we all know giving a particular incentive regardless of the industry will get things moving better. Direct incentives for a list of specified industries coupled with the ease of doing business will have investments pouring in. It’s sure true that the processes being followed currently would bring about a positive result but incentivizing the investments would yield an immediate result. Back to positive developments, govt’s initiatives in power, housing, infra, digitization is sure to pay dividends to all the industries. Housing for all, power for all and internet for all means a lot of business for the wire, cable industry in the coming future. Not only the above-mentioned industries, the emphasis the govt is putting on non- conventional sources of energy like solar is also a positive step for the wire & cable industry. There are a lot of DC based products that come into the market to specifically serve these particular segments. By the time these translate into field investments, the demand for the needed electrical would already be there, making it a positive outlook for the wire & cable industry. Increasing demand for power, light, communication has kept demand high for wire & cable. The wires & cables market in India comprises nearly 40% of the electrical industry. According to industry experts, it is expected to double in size in the next 5 years. The present estimated per capita consumption is only about 0.5 kg. As the new govt is focusing on Make in India, the industry can grow at a similar rate for the next 5 years. Talking about the power sector, copper holds high significance in terms of usage and consumption in this sector. The world average per capita copper consumption is around 2.7 kg. Electrical sector is the largest user of copper in India. Since copper and its alloy components play a vital role in electricity generation, distribution and utilization, 12-15% per annum demand growth in this sector is possible, if good quality is assured. Quality of Copper plays a very imp role in wire i.e. use of electrolytic tough pitch grade Copper wherein the purity of Copper in percentage terms should be min 99.90% as per national standards else poor quality of Copper used in wire may result in safety hazards as well as energy loss. According to industry experts, the wires & cables market is expected to double in size in the next 5 years. To ensure that copper is duly tested and verified for safety, in India we have IS 694 for PVC insulated wires for working voltages up to and including 1100V, IS 8130 for specification of conductor for insulated electrical wires and flexible cords. Additionally, the BIS issues ISI mark to all wire & cable manufacturers on compliance of minimum qualification criteria of above mentioned IS standards. The below aspects can ensure adherence to regulatory norms and encourage a good quality copper output: 42 NOVEMBER 2017 ||ELECTRICAL MIR R OR
Strict monitoring and compliance of qualification criteria by BIS before issuing ISI mark to wire manufacturers. BIS should ensure regular sample checks of all ISI issued wire manufacturers. consultants, A-grade contractors and project heads should approve the wire makes which should adhere to quality and maintaining resistance as per standards. Test of wire samples in large, medium and small projects should be mandatory Growing domestic market, govt’s priority for infrastructure development, copper in many end-use sectors, improved lifestyle, newer opportunities, etc. have all given a boost to the Indian copper industry. Going forward the demand for copper is expected more in the railways and automobile sector. India showed a 5% increase in copper wire rod used in wire & cable production for 2014, which is a vast improvement on the YoY reduction of 0.4% in 2013. In India wires are manufactured in organized as well as in the unorganized sector. The Indian power and cable industry has about a dozen producers in the organised sector, claiming more than two-thirds share of the market. The unorganised sector constitutes a few small units. The divergence in the two segments goes beyond their unit sizes. The two sectors exhibit significant differences in quality and capacity. While the organised sector has been manufacturing HV and specialty cables, the unorganised sector limits itself to the relatively LV market. The organised segment caters also to the industrial market. The electrical conductivity of copper is second only to silver and is 65% better than Aluminium, which makes it a preferred metal for wire & cable industry. Copper being harder, stronger and more ductile, expands less and does not flow at terminations and consequently does not require periodic inspection and tightening of screws. Higher copper content in transformers improves energy performance and consequently lowers lifecycle costs in most cases. The growing trend in the building construction & automobile sector is expected to keep demand of copper high. Understanding the copper technology involved in copper production, exploration, mining, and the uses of copper, as well as the global industry structure would impact the copper mining on the environment, the various markets of copper, etc. The industry is affected by the price trends of copper, market performance, import/export scenario, the physical market trends, demand for copper, and of course, a market forecast. Govt has made an ambitious plan. According to Indian Electrical Equipment Industry Mission Plan 2012-2022, the govt has planned to make India the country of choice for the production of electrical equipment and reach an output of $100 billion by balancing exports and imports. Requirement of electrical equipment is one of the most important inputs for development of the power sector.
Growth of the Industry
Industry experts forecast the global electric wire &
cable in India market to expand at a CAGR of 15.61 per cent during 2016-2020. Indian cable industry becoming more competitive with the entry of foreign players and growth of the domestic players. In India, the size of the cable manufacturing industry is approx Rs. 40k Cr. Specialized cable industry is roughly of the size of Rs. 10k Cr. Govt has announced ambitious plans for infra development. One of the primary focus area of the development plan is railways, with over Rs. 800,000 Cr as promised investment over the period of 2015-2020. In addition, the govt has earmarked Rs 50k Cr to develop 100 smart cities across the country. Highway projects worth US$ 93 billion, which include govt flagship National Highways Building Project (NHDP) with total investment of US$ 45 billion over next 3 years, have also been announced. Digital India campaign will require an investment of Rs. 4,50,000 Cr. Ministry of Power is also looking at an investment of 15,000 lakh Cr over the next 5 years. It is expected that the industry which has been growing at the rate of around 15% currently, will start growing at the CAGR of over 20% over the next 5 years. The future looks bright if the proposed plans take shape. In India we have two segments in cable manufacturing industry organized and unorganized. The wire & cable industry is organized in nature due to the availability of limited number of market players. There are approximately 65% organized players and 35% unorganized players in the wire & cable sector. Due to the tough competition from the countries like China, Brazil, South Africa and Saudi Arabia, Indian wire & cable companies lack a competitive edge in the international market. The quality and variety of wire & cable with its applications in different industries make it demanding in several countries. In the organized sector cables are produced with best raw materials as per specification, are duly tested during production at various stages and the final product is retested before dispatch. This makes the products from the organized sector more expensive vis a vis the unorganized sector. The cable Industry in the unorganized sector is mainly in-house building wiring industry, where no quality control is followed. The main reason being that the end user is also not aware of all quality requirements. However, the situation is changing. With slew of advertising and the publicity campaigns targeted at this segment, people are getting more and more aware about the quality of products in this category too and asking questions before deciding on the cables and wiring. This is a step in the right direction, since the safety and durability of electrical and electronic fixtures depends on these. Advertising is a positive step for our industry. But primary focus of these advertisements is towards house wires and not towards cables which are an industrial product.

Other prominent vendors in the India market are: Cable Corporation of India, Cords Cable Industries, Apar Industries Limited, KEC International, LS Cable India, Shilpi Cable Technologies, Universal Cable, V-Guard. One of latest trends in the India market is increase in sales of HVDC power cables. HVDC underground power cables have become viable options for long distance and high-voltage safe power transfer. HVDC power systems provide a viable option for long distance bulk power delivery. The European Commission has selected 43 major energy projects to build cross-border infra to create an internal energy market and enhance the security of energy supply. For these projects, high loads of electricity would be required to be transferred from one country to another. HVDC cables are expected to become a viable option for such assignments in the future. India is likely to follow this trend during the forecast period. In addition, these HVDC light cables find preference over their AC counterparts, especially in submarine power transmission, due to their lightweight and dimensions. One of the primary drivers in the market is growth in renewable power generation in India. A huge emphasis is given to the commercialization of renewable energy worldwide, which will create an enormous demand for electric wire & cables. This is because most of these renewable energy resources are set up in places where proper T&D infra is not available. Future expansion of existing networks worldwide is also expected. These expansion activities are fueled by emerging economies such as India, which are on the threshold of integrating regional grids to form a nationwide electric grid network to allow a seamless flow of electricity. All this calls for extensive T&D infra development activities. Furthermore, one of the major challenge in the market is compliance to regulations. Electrical wire & cable manufacturers in India are required to comply with various safety rules and regulations for the installation of power cable systems. These regulations are scripted and decided by regulatory bodies such as American National Standards Institute (ANSI), Institute of Electrical and Electronics Engineers (IEEE). International Electrotechnical Commission (IEC). The rules vary depending on the circuit voltage, temperature rating, and environmental conditions.
Buoyant Segments and Resource Risk
The power cable segment is to continue on the ascending growth path as there is much to be done as on power T&D, thanks to govt.’s continued emphasis on laying comprehensive power distribution and transmission network in the country. India has 44 NOVEMBER 2017 ||ELECTRICAL MIR R OR
been steadily moving towards increasing digitization and the commitment has grown much with the new dispensation unleashing programs like Digital India, Broadband Highway, etc. This increasing digitization has of course catapulted the demand for Optical Fibre Cables (OFC) networks and the manufacture of OFC. OFCs are gaining importance in the wires & cables market. Internet, Cable TV, burgeoning usage of smartphones and the rising demand for broadband services have caused massive sprouts of OFC installations in the country. To address this growing need for high speed data transmission, the govt. along with major organized sector players has been investing huge amount. According to a recent report published, the thriving automotive sector is one of the major forces influencing the wire & cable materials market in India. India is witnessing the flourishing automotive industry due to rising demand for commercial and personal vehicles and growing purchasing power. The Indian automotive industry has been reporting two-digit growth rates for years. Construction is one of the core sectors of India’s economy and the future of the industry is important for commodities. Construction cable and wire sector is about to see steep growth in demands in coming days owing to huge govt.’s spending in infra, smart cities, real estate boom, and housing explosion. The raw materials that are being used in the manufacturing of wire & cable are copper and aluminium as conductive material and plastic and rubber for insulation. Despite the fact that India has abundant reserves of metals, the raw material availability of copper & aluminium is the biggest challenge faced by the sector players. The rising price of raw materials is a big threat to stable price and production costs in wire & cable. The rising price of aluminium and copper is becoming a major issue as it has squeezed the profit margin of enterprises. Internationally, most countries usually opt variable pricing structures where certain fluctuations in the prices of raw materials automatically get adjusted in the prices of finished products. But in India, enterprises execute orders on fixed prices, so the varying prices of raw materials hit the manufacturers directly. The import dependency of the wire & cable sector in India is high as the mining of minerals to get the copper and aluminium for the manufacturing of wire & cable requires legal permissions and, because of environment protection, the permission is granted up to a certain limit. Therefore, the sector has high risk of foreign-market fluctuations on its production as it is directly related to the import of raw material.
GST effect
Fearing higher GST rates on wires, cables & electronic components could have a crippling effect on the manufacturers, industry associations have demanded
lower GST rate of 18% for these key products, said a media report. While the current effective tax rate for these products works out to be 18.12%, under GST they will be taxed at 28%. A delegation of various associations demanded to revise GST rates for products under the HSN Code 8544 (such as winding wires, coaxial cable and optical fibres) and HSN Code 8536 (such as electronic components like switches, connectors and relays) from the proposed 28%-18%. Current rate of excise duty and VAT on all wires, cables and electronic components across all the major states is 12.5% & 5% respectively, resulting into current effective rate of 18.12%. Industry fears that reclassifying cables, wires and electronic components falling under HSN Code 8544 and 8536 in 28% slab rate of GST, will lead to inflation as compared to the prevailing rate. The rate of GST on raw materials used for cables and wires is fixed at 18%. Charging higher rates on end products is absolutely unjustified. The cable and wires industries is labour intensive and already reeling under tremendous pressure due to power sector woes and operating at less than 50% of its installed capacity. Hence it will not be able to bare the differential tax burden of 10% on its finished goods. Cables account for almost 82% of the turnover of cables and wires industry. Wires and other products account for balance 18% of the total turnover of the industry. It is understood in the GST rules that; all the CAPEX items will be subjected to 18% GST. Different rates of GST for products will result into huge revenue leakage and subjecting the entire industry at 28% will shoot up the capital cost for the industries as well as end users.

The Month
VARIOUS VARIOUS CASE CASE STUDIES STUDIES ON ON OPERATION OPERATION AND AND CONTROL CONTROL SCHEMES SCHEMES FOR FOR GRID GRID SUB-STATION SUB-STATION Contd‌. Contd‌. 1. Introduction: For the last few months, the response
of the readers to the case studies on various incidents is overwhelming. Hence this month we are again choosing the write up on similar kind of studies for developing the synchronisation of practical observation to the theoretical concepts. The analysis of each incident being supported by actual observations had been described during the situation to add awareness amongst the operation, testing and commissioning engineers to know the cause of problems and be helpful for easy rectification of the problems. This can also help to develop economic schemes for the smooth running of the operation and control system in the Grid Sub-Station.
2.1. Melting of Isolator Contacts: For a 400/220 KV
Grid S/S, during a close in fault of current of 15 KA, it was observed with melting of isolator contacts even after actuation of concerned relay within 110 m Sec.
Investigation of the Case:
1. The fault affected line is of approximately 8km in length, where initial 2km is cable and remaining 6km overhead line. 2. Fault was at the seventh tower of overhead line from local end, approximately 4 kms from the station. 3. System is designed for 40kA for 1s. Male and

Er P.K.Pattanaik, is presently working with OPTCL as Asst. General Manager (Elect) in E & MR Division, Bhubaneswar- Odisha and associated with the Protection and Control schemes of Electrical systems. He is having 25 years of technical experience in Designing, Testing and Commissioning of Protection Control and operational Schemes, project Implementation, co-ordination, operations & maintenance of Electrical Equipments at various LT/ HT/ EHT level Grid Sub- Stations. He has also published around 70 technical papers in different national/international seminars/journals.
female contacts are melted at only one end. 4. Fault was in B phase and there was huge increase in voltage of Y phase during this fault. Y phase voltage raised approximately 1.732 times its rated value. 5. Only faulted phase contacts are melted and there is no damage in other phase contacts. Breaker opened in all three poles after trip. 6. The isolators were of Double Break contacts used in the system and close to a cement factory.
Analysis of the case:
1. This line was the combination of Cable and OH line and the fault occurred at 4 Kms from the station. 2. Total line conductor up to the point fault is of (2 Kms Cable + 2 Kms of OH line). 3. From the investigation data it is being found with rise of voltage on the healthy phase being 1.732 = root 3 times of the rated voltage. 4. This nature of root 3 time voltage rise indicates of the floating neutral or high resistive value in the fault path. But available of heavy fault current with rise of voltage indicates that the
ele.pkpattanaik@optcl.co.in
contribution is from other system and TRV has caused. Single break isolator has the chance of either remain in open condition or complete close, as this results final connection of dragging of both moving contacts towards each other, basically for 220 kV system. 5. But double break isolator has the problem of maintaining proper contact and CR (Contact reason on the system. So during fault condition of 15KA and the sudden outage (110ms) is the factor of the cause initiation of spark at any one of the contact from the available two contacts. Then initiation of spark with deposition of dust or foreign particles on it may cause aggravation of the fire resulting with melting of the contacts, even after outage of fault. 6. So it is advisable to use single break with proper arcing horn and dragging each other to result proper grip isolator. 7. Situation of asynchronous tripping of pole may result higher voltage appearance across contacts during slight loose condition.
2.2 Change of Tan delta value of CT: One of the
220 Kv CT was obtained with rise of Tan delta value from 0.3 to 3% within a span of 1 year, with no ||www.electricalmirror.net||
change in the capacitance value.
Investigation and Analysis:
1. The dielectric that used in the condenser grading has on technical way contains of two parameters (Capacitance and di-electric resistance). 2. The Capacitance of CT will change if there is a definite failure (partial) of condenser grading. Whereas Tan Delta shall change because of loss increase in Dielectric component. 3. Hence Capacitance change is not necessarily related to increase in Tan Delta. 4. Increase in tan-delta value is an indication of deterioration of its insulation may be due to contamination or thermal aging etc. 5. The capacitance value generally does not change remarkably .The Capacitance formed through the wrapping of layers of Kraft papers in between very thin aluminum foils form Capacitances in series. If any capacitance/ some capacitances get either shorted or damaged, shall result into increase in total capacitance of the CT. 6. There is no such direct relationship between the values of tan-delta and capacitance. 7. Trend analysis on different application of voltage can allow you to judge the condition. Develop the plotting of tan delta at 2kv, 5 KV and 10KV and tan delta vs KV plot is almost horizontal straight line then it suffers with no appreciable defect. 8. If slope is more and found with sudden change in tan delta values, then the dielectric has suffered remarkably and advice to replace the CT.
2.3. Induction effect on 33KV lines: This was
observed with heavy Induction effect on 33kv, 11kv lines crossing 765kv line, resulting problem during shutdown of the 33 KV, 11 KV lines
Investigation and Analysis:
1. Every current carrying conductor acts like magnet with development of flux around it. 2. When any other conductor comes into the field of this flux results with certain induced emf. Moreover the electrostatic induction is more prominent in this case.
3.
Possible Solutions:
a. Maintain proper line clearance. b. Allow the crossing of the line at right angle to each other. c. Crossing to be done with earthed screen cable. d. Use underground XLPE cable in this area. e. Use metal guard caging over the 11 kV / 33 ||www.electricalmirror.net||
kV lines and this caging has to be connected to ground and AB cable with middle metal wire of higher cross section and the metal wire has also to be connected to ground.
Action Taken:
Final solution was used with METAL guard caging being connected to earth at the metal pole structure.
2.4. Non-trip of Auto-Transformer on Primary protection: Two 100 MVA Autotransformers were
running parallel. Bushing of one of the transformer (AT-1) failed causing the tripping of primary protection (differential Relay) and other protection and outage of the transformer, but other transformer ( AT-2) winding was also stressed due to this surge and result with inter-turn fault but not tripped on Differential relay and was tripped on PRV.
Analysis Extended as follows:
1. Case of Di-electric failure of Bushing that leads to an earth fault in the form of arcing between the bottom of the bushing and transformer tank and due to voltage surge. 2. Now due to parallel operation and propagation of this voltage rise, causes stress upon the winding of affected Y phase and results inter-turn short. 3. Short circuit of few turns on the winding may give rise of higher fault current but restricted to the affected turns. But its effect on primary side due to higher Ratio may not be sufficient for detection by differential relay. 4. However the oil surge due this effect becomes sufficient for the actuation of PRV and outage of the transformer. 5. The type of fault that occurred in Auto1, which was external to transformer winding, but inside the zone of CT for which primary protection operated to isolate the fault. 6. But the type of fault being external for the AUTO2, shall neither cause the actuation of
its directional OC Relay nor restricted zone diff or REF relays. 7. But doubt comes if Auto1, where the fault had been occurred, if successfully had cleared the faulty part due to actuation of its primary relays, then how the other AUTO got affected ( May be due buckling, twist or deviation of the winding for the inter-turn fault. 8. So this incident clearly indicates regarding the impact of load outage and sudden rise of load on this available Auto2 with abnormal appearance of voltage on the system. 9. For strong analysis thought we can add information that this station is nearby a 400KV PGCIL system being fed with HV source network. So this strong source could be the reason of abnormal electrical parameters and distortion of winding on the AUTO2. But the inter-turn short as very small on the affected Y phase might not have resulted the required abnormal current on differential relay. But the oil surge being high has resulted the tripping of PRV relay
SOLUTION
1. From Protection point of view, we should have the followings a. Use High Set Instant element on back up Relay with Non-directional feature. b. High voltage setting with definite trip has to be activated. c. Soon Impedance relay with Zone selection has to be used in the system. d. Use of 2 nos PRDs of 160 mm size at diagonally opposite positions to give max coverage.

heat and melt of the welding lead). 7. Here supply neutral was of not proper and the welder might not have maintained proper return path to the supply source (welding machine). 8. Moreover in maximum situation it happens that if the return path of the welding system is not proper then welding shall not spark and welder decides the job to be properly earth with the source. 9. But in this case the return path to the welding job was through the armoured sheath (that double point connected at Transformer end and ACDB end) So the sheath as carrying the weld current got heated and resulted the burning of the cable ( fig 2.4.3).
Recommendation: When any welding job needs to
be undertaken, the return path should be properly checked, particularly during welding of any earthed conductor.
2.4. Burning of Armoured Sheath: While welding
the earth flat connected to Earth pit of LV neutral of Station Transformer, the armoure of the 4 core Power Cable from Station Transformer to ACDB was burnt.
2.5: De-coil of Wave Trap: It was observed with the
deformation of Wave trap coil during the occurrence of fault in the line.
Observations
1. This was a new Grid Sub-station, where this 33/0.4 KV Station transformer was under commissioning stage. 2. The construction supply was getting available from another transformer with its neutral temporarily connected to its earth pit. 3. During commissioning installation stage of this new transformer, the LV Neutral (0.4 KV side neutral flat coming from the neutral bushing) was attempted to connect to the individual Earth pit as shown in the figure 2.4.1 and Fig 2.4.2). 4. The 4 core cable (Supply cable), was connected at Transformer end but not connected to any equipment at remote end. 5. But the supply cable armoure was earthed at both transformer and ACDB end. 6. So during welding (the principle of more current drawal in the system causing required

Observation:
1. There was a heavy fault in the system on the R phase of the line. 2. In general fault clearance gets managed by two different methods. a. The proper earthing to cause fault current to dissipate.
b. Proper protection scheme and actuation on the early possible time. 3. In this condition though the timing had not been recorded, but seems to be slight delay. 4. The earthing could also be the cause of delay of the fault current. 5. As per the normal observation, it is seen that this kind of de-coiling results during the case of heavy fault situation.
Action Plan: The displaced wave trap was replaced
with proper checking of protection scheme and earth system. 2.6. Burning of NEUTRAL core: In one of the process industry, it was observed with repeated failure of the AC supply cable. The neutral core was only burning during the running of the furnaces and SCR control boards.
Observations:
1. The supply cable was of 3 and 1/2 core cable (The cross section of the neutral core was of half cross section that of phase core). 2. The current rating of the cable was well within the rating of the cable. 3. This was supplying the system feeding to inverters in the board and fluctuated control supply to Induction furnaces. 4. The kind of loads as described were of un-balance type and of resulting with harmonics in the system. 5. This type of un-balance and harmonics linked current usually passes though the neutral core and as of its cross section being half of the phase one, may not be that sufficient to manage the current flow. 6. So it was burning always and the users not understanding the reason were replacing the same with the similar kind of cable.
Solution:
1. The detail loads as distributed on the downstream were reviewed and managed as per possible way in balancing manner. 2. The harmonics reducer circuit was connected and the monitoring relay with tripping outage scheme was introduced in the relay. ||www.electricalmirror.net||

The Import Conundrum of CRGO & CRNGO in Transformer Manufacturing
T
he iron core transformer has higher permeability thus it is applied in transformer in place of air core in modern transformer. But a solid iron core has some own disadvantage due to some losses. Thus, to reduce the losses solid core is not used in transformer. Thin & laminated iron core is stacked up to form the complete core. This individual core is electrically separated from each other as this thin coating layer is an insulating material but let passes the magnetic flux. When flux flows in the steel core, losses occur in the steel. There are two components of this loss, which are termed “eddy” and “hysteresis” losses. If a solid core were used in a power transformer, the losses would be very high and the temperature would be excessive. For this reason, cores are laminated from very thin sheets, such as 0.23 mm and 0.28 mm, to reduce the thickness of the individual sheets of steel normal to the flux and thereby reducing the losses. Each sheet is coated with a very thin material to prevent shorts between the lamination. The hysteresis loss is caused by the cyclic reversal of flux in the magnetic circuit and can be reduced by metallurgical control of the steel. That is by choosing the material of steel. Eddy loss is caused by eddy currents circulating
50 NOVEMBER 2017 ||ELECTRICAL MIR R OR
within the steel induced by the flow of magnetic flux normal to the width of the core, and it can be controlled by reducing the thickness of the steel lamination or by applying a thin insulating coating.
Development of CRGO
In recent years, as an aspect of the global trend towards energy consumption and preservation of the environment, the reduction of electrical consumption has become an extremely essential affair. Due to such worldwide movement of environmental protection, energy saving and noise reduction have been required for transformers, leading to a demand for lower core loss and lower magnetostriction material. Silicon steel is a soft magnetic material mainly used for transformer cores. Silicon steel is a material of prime importance in the electrical industry and is been consumed in hundreds of thousands of tons every year. Pure iron has exceptional magnetic properties. One of the properties is its very high saturation magnetization and its about 2.17 T at room temperature. Pure Iron is, however not used for electrical applications, instead electrical steels are used in many engineering applications. Electrical steels are also absolutely needed for the
electrical power industry, as there are no obvious cost-effective alternative materials available. Most electrical steels are Fe alloys with characteristic alloying additions. The most imp. alloying elements are silicon & aluminum. In electrical steels, Si and Al are in solid solution and they influence the α- phase and ϒ-phase stability. Both are strong ferrite-stabilizing elements and their addition may limit the austenite phase stability to the extent that is not present during heat treatment. In 1900, the reducing effect of iron loss due to an addition of silicon in iron was discovered by Hadfield. Concept of orienting grains in magnetically favorable direction was discovered by N.P. Goss in 1934 and corresponding texture {110} is referred as Goss texture, also called Cube-on-edge (COE) orientation with {110} indicating the plane and indicating favorable magnetic flux direction. Norman P Goss patented the method to manufacture CRGO steel in 1934 under the name of “Electrical sheet and apparatus for its manufacture and test”. Before Goss’ invention, production of electrical steel was more or less based on hit and trials. Methods weren’t known to check the ||www.electricalmirror.net||

characteristic of the material before its production. In CRGO Steel pioneered by ARMCO, USA and Allegheny Ludlum Corporation (ALC), this type of texture was developed utilizing different process technologies during 1940-50 period. The cold rolled Grain Oriented steel containing about 3% Silicon replaced the HR silicon Steel containing 4 to 4.5% Silicon which was used as Transformer core-material till 1940s. Subsequently, both ARMCO and ALC transferred CRGO Process technology to several other manufacturers, who produced conventional CRGO steel under License from either of the two companies mentioned above. ARMCO Licenses: Nippon Steel- Japan, Usinor-France, Surahammer Sweden, Acesita-Brazil, SAIL-India, ALC Licenses: POSCO-KOREA, Raymond Steel- India.
Currently, India consumes about 2.5 lakh MT per annum of CRGO electrical steel and with the growth in demand of transformation capacity the consumption is estimated to be 11.5 Lakh MT and 13.5 Lakh MT respectively during the 12th and the 13th plan period. Against the above demand, only SAIL-RSP and Raymond steel have CRGO Production facilities. SAIL produced a small quantity in early 1990s and thereafter discontinued CRGO production. Only five global steel makers have the technology to produce such steel, which India imports around USD 2 billion annually. The plan to produce CRGO has been with steel ministry for quite some time. National Metallurgical Laboratory (NML) and Tata Steel's proposal for development of CRGO steel in the country through a pilot plant setup at a cost of Rs 500 crore is set to take off soon. NML and Tata Steel would set up a pilot plant having a capacity of 3-5 tonnes in Jamshedpur. The two will give Rs 170 crore each to the project and the balance is likely to be funded by the Steel Ministry for procuring plant equipment. NML is the third in the Council of Scientific & Industrial Research (CSIR) family of 38 laboratories. The Working Group on Steel Industry for 12th Five-Year Plan in its report had recommended inclusion of development of CRGO steel as a high value project of national importance. It had also suggested a budgetary allocation of Rs 150 crore for research on CRGO development during the 12th FYP period. There
are a couple of public sector companies including JSW Steel, that have already announced plans to produce CRGO through JV mode, but production from them will take some time to start. Public sector units - SAIL and RINL - have also evinced interest to venture into the area. However, Steel Ministry's Empowered Committee (EC) for R&D, headed by the Secretary, said the joint ventures undertaken by Indian steel firms cannot ensure total technology transfer. Even if they do, it will cover only normal grades. Steel firms having the technology to develop CRGO are very reluctant to transfer that to India. EC, hence, felt that dev of the technology through indigenous sources through a pilot plant was a necessity. According to CEA, transformer industry of the country has grown to a manufacturing capacity of 800-1000 GVA and during the 12th Plan period, an additional 94,000 MW generation capacity is targeted to be added. Given these daunting req’s, the need for higher capacity transformers is imminent. India's CRGO steel consumption thus would sig. increase from the current level of $ 2 billion. In 1900, Hadfield discovered the reduction of core loss on addition of Si and in 1934 Goss patented the industrial method to produce GO steel, it travelled a long way since then. In 2010, around 400 million tons of electric steel were produced worldwide, making around 29% of total steel production. The share is close to about 50% in Europe and to some extent even sig. higher in North America, Africa, India and the Near East. In total production of GO steel, percentage of high grade GO steel, HI-B is still around 20%, which is a very small when compared to the benefits of HI-B. This is due to many metallurgical problems observed in production of HI-B such as high slab reheating temp (>1300 OC) for the formation of Austenite phase in desired percentage, restriction in increment of Si percentage (to decrease core loss) and restriction in decreasing the gauge of product. But new developments are also taking place like acquired inhibitor method, in which N2 gas is injected by using NH3 gas after decarburization. This method decreases reheating temperature of slab and hence ensures the better performance of electrical machines. This is just an example of the possibility of new techniques which can be discovered with research in this area. Such inferior material causes transformers to fail faster debilitating the country's power distribution infra. Thus, CRGO is going to play an imp. role in sustaining India’s economic development. Hence, focus should be given in R&Ds of high grade GO in India.
Application of CRGO and CRNGO
Grain oriented Electrical Steel CRGO is undoubtedly the most imp. soft magnetic material in use today. Whether in small transformer, distribution transformer or in large transformer & generator, grain oriented electrical steel CRGO is a must for the production
52 NOVEMBER 2017 ||ELECTRICAL MIR R OR
of energy saving electrical machines. Grain oriented Electrical Steels are iron-silicon alloys that provide low core loss and high permeability needed for more efficient and economical electrical transformers. CRGO Grain oriented grades of electrical steel are typically used for transformer cores and large generators. Non-oriented Electrical steel CRNGO fully processed steels are iron-silicon alloys with varying silicon contents and have similar magnetic properties in all directions in plan of the sheet. Non-oriented Electrical steel are principally used for motors, generators, alternators, ballasts, small Transformers and a variety of other electromagnetic applications. The earliest soft magnetic material was iron, which contained many impurities. Researchers found that the addition of silicon increased resistivity, decreased hysteresis loss, increased permeability, and virtually eliminated aging. Substantial quantities of Grain Oriented Electrical steel CRGO are used, mainly in power & dist. transformers. However, it has not supplanted non-oriented Electrical steel, which is used extensively where a low-cost, low-loss material is needed, particularly in rotating equipment. Mention should also be made of the relay steels, used widely in relays, armatures, and solenoids. Relay steels contain 1.25-2.5% Si, and are used in DC applications because of better permeability, lower coercive force, freedom from aging.
Key physical properties of CRGO
It includes resistivity, saturation induction, magnetocrystalline anisotropy, magnetostriction, and Curie temperature. Resistivity, which is quite low in iron, increases markedly with the addition of silicon. Higher resistivity lessens the core loss by reducing the eddy current component. Raising the silicon content will lower magnetostriction, but processing becomes more difficult. The high Curie temperature of iron will be lowered by alloying elements, but the decrease is of little importance to the user of CRGO Electrical steels. The magnetization process is influenced by impurities, grain orientation, grain size, strain, strip thickness, and surface smoothness. One of the most imp. ways to improve soft magnetic materials is to remove impurities, which interfere with domain-wall movement; they are least harmful if present in solid solution. Compared with other commercial steels, Electrical steel is exceptionally pure. Because carbon, an interstitial impurity, can harm low induction ||www.electricalmirror.net||
permeability, it must be removed before the steel is annealed to develop the final texture. The mechanism for the growth of grains with cube-on-edge orientation during the final anneal is not completely understood. The process involves secondary recrystallization, which, by definition, is characterized by accelerated growth of one set of grains in an already recrystallized matrix. For secondary recrystallization, normal grain growth must be inhibited in some manner. As the temperature is raised, certain grains break loose from the inhibiting forces, and grow extensively at the expense of their neighbors. Producers know that, on a practical basis, appropriate cold rolling and recrystallization sequences must be carefully followed to obtain the desired secondary recrystallization nuclei and the correct texture. Today`s Electrical Steels use MnS as the grain growth inhibitor, but other compounds, such as carbides, oxides, or nitrides, are also effective.
CRGO Making and using
It is more restricted in composition than non-oriented varieties. The texture is developed by a series of careful working and annealing operations, and the material must remain essentially single-phase throughout processing, particularly during the final anneal because phase transformation destroys the texture. To avoid the y loop of the Fe-Si phase system, today's commercial steel has about 3.25% Si. Higher silicon varieties, which might be favored on the basis of increased resistivity and lower magnetostriction, are precluded by difficulties in cold rolling. Temperature, atmosphere composition, and dew point are closely controlled to decarburize the strip without oxidizing the surface. During this treatment, primary recrystallization occurs, forming small, uniform, equiaxed grains. The coating of magnesium silicate glass which forms will provide electrical insulation between successive laminations when assembled in a transformer core. At this stage, the Electrical steel is graded by cutting Epstein samples from the coil; the samples are stress relief annealed and flattened at 790°C, and tested for core loss. Applications for CRGO include transformers (power, distribution, ballast, instrument, audio, and specialty), and generators for steam turbine and water wheels. Lay-up cores, in general, utilize the whole spectrum of grain oriented Electrical steel CRGO quality and gages. The gage and grade of material for a given application are determined by economics, transformer rating, noise level requirement, loss requirements, density of operation, and even core size. Because the strip must be flat to produce a good core, coils are flattened after the high temperature anneal. Then, the strip is coated with an inorganic phosphate for insulation. Samples from each coil end are graded after a laboratory stress relief anneal. From such strip, the transformer manufacturer cuts his required length improves the insulation of the strip. Consequently, it ||www.electricalmirror.net||
decreases the eddy current losses and heat buildup, which is of particular importance in transformers which must withstand an impulse test. As noted earlier, an imp. requirement in the manufacture of lay-up cores is minimizing transformer noise. Noise is a function of manufacturing and core design factors, the core material characteristic being one of most imp. The dependence of magnetostriction on silicon content has already been noted. In addition, magnetostriction is reduced by improving the texture and by introducing tensile stresses through application of glass-type insulation coatings. Because compressive stresses affect magnetostriction adversely, it is imp. that the lamination remains flat for assembly. Operating induction is also a factor that affects noise, and indeed affects transformer’s general operating characteristics. Operating inductions of lay-up transformers are usually in the 10,000-17,000 G range; power ratings extend over the 500-1,000,000 kVA range. Wound cores are wound toroidally with the crystallographic direction around the strip. Processing steps are somewhat different from those used for lay-up transformers though the starting material is the same-large toroidally annealed coil coated with magnesium silicate, which usually provides sufficient insulation. Grain oriented Electrical steel CRGO for wound core application, unreacted MgO powder is removed from the strip surface, and a sample from each coil end is cut into Epstein strips to be tested as before. After being graded, the coil is shipped to the transformer manufacturer either as slit multiples or as a full-width coil for subsequent slitting. The slit multiple, wound to the given core dimension, must be stress relief annealed at 790°C in a dry nonoxidizing atmosphere. Annealing trays and plates must be of low carbon steel to eliminate any carbon contamination, which can be very detrimental to quality. After CRGO being stress relief annealed, the cores are cut, and the CRGO transformer core is assembled by lacing the steel around the copper (or aluminum) current-carrying coils. In the stress relief annealed condition, grain-
oriented steel CRGO electrical steel is sensitive to mechanical strain; therefore, cores must be assembled carefully. Regardless of how carefully assembly is accomplished, the final core quality is always poorer than it was in the stress-relief annealed, uncut condition. The difference in quality, commonly referred to as the destruction factor, is due to the relative strain sensitivity of the grain-oriented CRGO steel, the handling procedure in fabrication, and the uniformity and amount of air gap in the core. Being a function of the transformer design and fabrication, the latter two factors are controlled best by the manufacturer. Most CRGO wound cores are utilized in dist. transformer applications of 25-500 kVA.
CRNGO Making and using
Non-oriented electrical steels do not use a secondary recrystallization process to develop their properties, and high temperature annealing is not essential. Therefore, a lower limit on silicon, such as is req. for the oriented grades, is not essential. Non-oriented electrical steel grades contain between 0.5 & 3.25% Si plus up to 0.5% Al, added to increase resistivity & lower the temp of primary recrystallization. Grain growth is very desirable in the CRNGO, but is generally much smaller than for the oriented electrical steel CRGO grades. Processing to hot rolled band is similar to that described for the oriented grade. After surface conditioning, the bands are usually cold rolled directly to final gage, and sold to the transformer manufacturer in one of two conditions fully-processed/ or semi-processed. After final cold rolling, the strip is annealed, decarburizing it to 0.005% C or lower and developing the grain structure needed for the magnetic properties. Samples are then taken from each coil end, and tested. CRNGO Fully processed non-oriented Electrical steels are generally used in applications in which: Quantities are too small to warrant stress relieving by the consumer/CRGO Laminations are so large that good physical shape would be difficult to maintain after an 843°C stress relief anneal. Non-oriented steels CRNGO are not as sensitive to strain as the oriented

product. Consequently, shearing strains constitute the only strain effects, which should degrade the magnetic quality. Because laminations are generally large, these shearing strains can be tolerated. Most of the fully processed grades are used as stamped laminations in such applications as rotors and stators. CRNGO have a random orientation. They are commonly used in large rotating equipment, including motors, power generators, and AC alternators. Fully processed steels are given a full strand anneal, making them softer and more difficult to punch than semi-processed products. Grades with higher alloy content are harder and thus easier to punch. Improved punchability can be provided in fully processed steels by adding an organic coating, which acts as a lubricant during stamping and gives some additional insulation to the base scale. If good inter-lamination resistance is required, fully processed material can be purchased with core plate. Semi processed electrical steel CRGO products are generally given a lower-temperature decarburizing anneal after the final cold rolling. Carbon is not necessarily removed to the same low level as in fully processed material. The transformer manufacturer will subsequently stress relief anneal the material in a wet decarburizing atmosphere to obtain additional decarburization and develop the magnetic properties. Samples are taken after the mill decarburization anneal, cut into specimens, decarburized at 843°C for at least one hour and tested to grade the coil. Semi processed CRGO non-oriented electrical steels are used for applications in which the customer does the stress relief anneal. In general, such products have good punching characteristics, 54 NOVEMBER 2017 ||ELECTRICAL MIR R OR
and are used in a variety of applications including small rotors, stators, and small power transformers. Semi processed electrical steels can be purchased with a tightly adherent scale, or with an insulating coating over the oxide. The organic coating acts as a lubricant during punching, but it does not withstand stress relief annealing temperatures; therefore, it is not applied to semi-processed material.
Production processes for CRGO
Slitting CRGO Electrical steel comes in the form of wide coils having widths of 750 mm to 1000 mm. These coils are to be slit in various widths in steps ranging from 10 mm to 100 mm. Winding These slit coils of CRGO are wound on semi-automatic winding machine as per the dimensions given by our customers. Spot Welding On winding the CRGO Toroidal cores to the exact size the start and finished ends of the core are spot welded on spot welding machine. Stress relief annealing During the winding process of CRGO, severe stresses are induced in the gains of the raw material. Theses stresses are relieved in our specially designed annealing furnace equipped with automatic temperature controller, circulating fan and inert atmosphere. The annealing cycle (at 800°C) improperly controlled to get uniform and best annealing results. Testing Since the CRGO electrical properties of cores are very critical, every core is tested on a specially designed test bench. The ampere turns/ cm are measured on every core to ensure that they are within the specified limits. Painting After testing the 'PASSED' cores are painted with N.C. paint to prevent the CRGO Toroidal cores from corrosion. Packing the Electrical Properties of CRGO Toroidal cores are very
sensitive to bad handling during transit. Needs great care while packing the cores in wooden boxes with cushioning material to prevent stresses on the cores during dispatch.
Import duty cut on inputs of CRGO steel
As per recent CBEC notification, import duty on hot rolled coils, coldrolled Magnesium Oxide (MgO) coated and annealed steel, hot rolled annealed and pickled coils, cold rolled full hard which are the inputs used for the manufacture of cold rolled grain oriented steel (CRGO) has been reduced to 5%. CRGO steel is used for the cores of electrical & power transformers and other electrical appliances. This steel product is largely imported as the country lacks the capability to produce CRGO steel. With this announcement, the import duty on raw material used for the manufacturing of CRGO steel has reduced which will reduce the input cost. This, in turn, is expected to give some encouragement to domestic steel producers to produce CRGO steel that is imported. In May’17, the govt imposed anti-dumping duties on import of hot and cold-rolled flat steel products. This included 47 steel products that originates or are exported from China, Japan, Korea, Russia, Brazil and Indonesia.

Fig:1 Imports of CRGO steel (in USD million)
The imports of CRGO steel increased in double-digits for the years 2014 & 2015. On a YoY basis, it grew by 29.9% to USD 433 million in 2014 and by 18.2% to USD 511.6 million in 2015. Following this, the imports declined by 5.5% to USD 483.5 million in 2016. The imports of CRGO steel are mainly made from Japan. Of the total imports (in value terms) of CRGO steel made by India in 2016, 25.6% of the imports were from Japan followed by 22.9% from Russian Federation, 14% from Republic of Korea, 10.7% from China, 6.7% from USA. The govt recently gave nod for the policy that provides preference to domestically produced steel to be procured by the govt for its projects. The import duty cut on the input products for CRGO steel will reduce the cost of its manufacturing. It is believed that that this move will encourage the domestic producers to produce CRGO steel that is otherwise imported, which in turn would mean reduced costs for electrical and power transformer & lamination CoS.

Afterword
CRGO is an imp & critical input in transformers. But, it is also an input not manufactured in India and hence we are completely reliant on int’l imports. A view has been taken in some sections that low grade of CRGO being imported into the country has been responsible for inferior quality & frequent failures of transformers which is not correct. While it may play a role in the energy efficiency of transformers, no transformer analyst/ engineer would be able to significantly link lower grade of CRGO with failures in transformers. Moreover, the problem of failure of dist. transformers cannot be solved through controls on import of CRGO steel. A more rational view would be to have a transformer quality control order whereby the quality of the end product is ensured. CRGO is one of the major raw materials used in manufacture of transformers. It is imp. that any raw material coming into the country should be of good quality but in this case global steel mills that produce CRGO have standards which are stricter than BIS standards. However, there is a problem in it being made applicable selectively only for transformers to be used in the country. Why we need one set of standards for domestic products and another set of standards for
||www.electricalmirror.net||
products exported out of the country. As the provisions stand today, low grade CRGO is unacceptable in our country, but is perfectly acceptable in goods being supplied overseas with the “Made in India” label? The premise on which CRGO was included for mandatory compliance with BIS standards was that low grades are resulting in higher failures of transformers. For a moment, accepting this premise, it would infer that transformers exported from our country shall fail within a short span as the CRGO used therein is not subjected to any mandatory compliance with BIS standards. Secondly, this is also not required for transformers being imported into the country. Why is it that domestic manufacturers should be subjected to a stringent standard which is not applied for transformers imported from overseas? Another problem an artificial scarcity has been created with prices of CRGO going up. Govt is planning for major reforms in the distribution sector. Both scarcity of CRGO and higher prices being charged by int’l mills would mean increased cost of transformers and resultantly greater financial burden on the discoms and the govt. This could never have been the intention for bringing in CRGO under mandatory BIS certification. It is heartening that a large no of stakeholders, including officials in the govt have started realizing the futility of the Steel Control Order, especially when the transformers have been brought under mandatory BIS certification. Deliberate use of scrap CRGO in dist. transformers has had menacing implications on the T&D sector. The steel quality control order is indeed a welcome step as it seeks to weed out the use of inferior scrap CRGO from source. However, there is much that the govt would need to do to ensure that prime grade CRGO is available to the Indian consumer at a fair price. So far, 8 mills have got their products BIS certified. An equal no of mills has yet to get their certification in place. It is only when more & more mills get their products certified will supplies be in a comfortable position. At the moment, the supply of BIS certified CRGO is limited and there is a likelihood of suppliers forming a cartel to increase their prices. If the steel quality control
order is implemented effectively, many marginal transformer manufacturers that have thrived on the willful use of scrap CRGO will either move up to join the formal class of manufacturers, or will simply exit the business. Any way, it will help the power sector and the economy at large. Hence Govt must move briskly in creating local manufacturing capacities for CRGO. In some sense, the steel quality control order should have come after domestic manufacturing capabilities were established. Govt would also need to establish testing facilities for checking if imported CRGO conforms to BIS standards. Prime grade CRGO is a matter of choice for manufacturers regardless of the regulations. The area of concern is the sprawling class of dist. transformers that have made a business out of intentional use of scrap CRGO. It is likely that some of these will demonstrate the same spirit and find innovate ways to circumvent the mandatory requirement of prime grade CRGO. There are also some anomalies in the Steel Quality Control Order that need to be looked into. Firstly, there is no check on the quality of CRGO used in imported transformers. Secondly, even during export of transformers, there is no clarity on whether BIS certification on CRGO would be insisted upon. Govt has shown seriousness in cracking down on deliberate use of scrap CRGO. It is only hoped the noble move will eventually meet its desired objective.

Power is one of the most critical components of infrastructure crucial for the economic growth and
welfare of nations. The existence and development of adequate infrastructure is essential for sustained growth of the Indian economy. India’s power sector is one of the most diversified in the world. Sources of power generation range from conventional sources such as coal, lignite, natural gas, oil, hydro and nuclear power to viable non-conventional sources such as wind, solar, and agricultural and domestic waste. Electricity demand in the country has increased rapidly and is expected to rise further in the years to come. In order to meet the increasing demand for electricity in the country, massive addition to the installed generating capacity is required. India ranks third among 40 countries in EY’s Renewable Energy Country Attractiveness Index, on back of strong focus by the govt on promoting renewable energy and implementation of projects in a time bound manner. India has moved up 73 spots to rank 26th in the World Bank's list of electricity accessibility in 2017, according to Power Ministry. In Sep’17, GoI launched Saubhagya scheme to provide electricity connections to over 40 mn families in rural and urban areas by Dec’18 at a cost of US$ 2.5 bn. Indian power sector is undergoing a significant change ||www.electricalmirror.net||

that has redefined the industry outlook. Sustained economic growth continues to drive electricity demand in India. GoI’s focus on attaining ‘Power for all’ has accelerated capacity addition in the country. At the same time, the competitive intensity is increasing at both the market and supply sides (fuel, logistics, finances, and manpower). Total installed capacity of power stations in India stood at 330,260.53 MW as on May’17. MoP has set a target of 1,229.4 BUs of electricity to be generated in the financial year 2017-18, which is 50 BU’s higher than the target for 2016-17. The annual growth rate in renewable energy generation has been estimated to be 27% and 18% for conventional energy. Govt has added 10.2 GW of conventional energy generation capacity. The total solar power capacity addition from new installations in India in the first half of 2017 reached 4,765 MW and has exceeded the total capacity addition done in 2016. 2 under-construction hydro projects of NHPC in HP & J&K, expected to be commissioned in 2018, will produce 4,458.69 mn units of additional power, according to power ministry. A total of 13,872 villages out of 18,452 un-electrified villages in India have been electrified up to 30 Jun’17 as part of the target to electrify all villages by 1 May’18. A total of 26.3 mn households which are BPL have been electrified under the Rural Electrification component of DDUGJY.
Focussed Reforms over the past 3 years
India’s power sector that was marred by continuous shortages and lack of quality & steady supplies to homes, factories seen an unprecedented turnaround in the past 3 years. Today the country boasts of a situation where surplus power to the tune of 3,0004,000 MW is available on real time basis at any time of day to states and discoms and at affordable rates on the power exchange. Ease of getting power at affordable rates comes on the back of focussed reforms unleashed by the govt over the past 3 years in the power sector, Within 3 years, India’s total power capacity has increased by nearly one third and the conventional/coal based power capacity (which is the mainstay of the country’s overall power capacity) has increased by one fourth. Energy shortages in 2014 were 42,428 mn units (4.2%), which came down to 7,459 MU in 2017 (0.7%). Similarly, peak energy shortage in 2014 was 6,103 MW (4.5%) which came down to 2,608 MW (1.6%) in 2017. The power generation growth in the past 3 years is 6.4% from 2014-2017 (provisional). Generation growth would have increased further but for Energy Efficiency activities like UJALA, which have been the focus of our Govt since 2014. In 2014-16, growth was 6.9% & if we add the generation avoided due to energy efficiency activities it was 9.5% Significantly, India has turned around 58 NOVEMBER 2017 ||ELECTRICAL MIR R OR
from a net importer of electricity to net exporter of electricity exporting around 5,798 Mn Units to Nepal, Bangladesh and Myanmar in 2017 As generation alone cannot drive the sector, appropriate measures have also been initiated in the power transmission sector that too witnessed an impressive growth over the past three years. In line with the govt’s “One nation, One price and One grid” initiative, the transmission sector witnessed as much as 36% (One third) increase in transmission capacity from 5,30,546 MVA in Mar 14 to 7,22,949 MVA in Mar’17. Alongside, the transmission lines saw a 26% (One fourth) increase from 2,91,336 circuit kilometres (ckm) in March 14 to 3,66,634 ckm in Mar’17. Then there has been an 87% increase in Alternate Transfer Capacity to South India from 3,450 MW in Mar’14 to 6,450 MW in March 17. The growth in the sector was aided by simultaneous reforms on the rural front under the Modi govt’s flagship program to provide electricity across all villages in the country. Rural Electrification under DDUGJY was a programme announced in 2014 to connect un-electrified villages and transform the lives of rural people. The number of un-electrified villages in 2014 stood at 18,452. This program, that was given a special focus under the reform programme of the govt, achieved a new milestone of more than 13,123 villages of 18,441 electrified as on May 12, 2017. The talk of reforms in the power will be incomplete in the absence of a mention of the energy efficiency movement through UJALA (Unnat Jyoti by Affordable LEDs for All). The energy efficiency drive saw distribution of nearly 23 crore LED bulbs by the Govt along with 33 crore by the private companies, a move that resulted in savings of over Rs. 20,000 crore per year in electricity bills of consumers. Govt’s lead agency for this program, the Energy Efficiency Services Ltd (EESL) did not restrict this drive to mere distribution of energy efficient bulbs but also fans, air-conditioners, tube lights (for urban areas) along with energy efficient agricultural pumps for the farmers in rural India. The largest contributor in India’s power reforms story is the govt’s Ujwal DISCOM Assurance Yojana or UDAY scheme for turnaround of state distribution entities, that were considered as the weakest link in the entire chain of power sector reforms. According UDAY was launched by the govt to develop sustainable power distribution companies. Within three years, we have a total of 27 States and UTs who have joined this scheme for financial and operational turnaround. The scheme has already yielded savings of nearly Rs 12,000 Crores to the state power distribution companies. Almost 85% UDAY Bonds have already been issued (Rs. 2.32 lakh cr out of total Rs. 2.72 lakh cr) leading to less rate of interest for DISCOMs. Transparency has been the major driving factor behind this govt’s major reform initiatives. In the power sector alone, in order to empower customers track
the working and performance of the ministry and its companies on real time basis, the power ministry has launched various mobile Apps and websites to ensure transparency and accountability. These includes the GARV (Rural Electrification) App that provides updates related to the electrification of villages and households in India; the Ujala (LED bulbs) App provides real-time updates on the LED distribution; Vidyut Pravah (Power Availability & Price) App giving real-time information on electricity price & availability; URJA (Urban Jyoti Abhiyaan) APP to help enhance consumer connect by showing DISCOM's performance in cities and gives data of the Integrated Power Development Scheme (IPDS), the TARANG (Transmission System Monitoring) App to monitor the progress of Transmission System in India; UDAY that gives the progress of the UDAY yojana which assures the permanent resolution of all past, present and future issues of DISCOMs along with the latest kid on the block or the Urja Mitra APP that enables the citizen to access real time and historic outage information for DISCOMs. India’s power sector has indeed taken rapid strides during the past three years and the process or reforms continues unabated. The reforms in the sector today are recognised by all across the globe. From ranking 99th at the global level in 2014 in terms of electricity accessibility ranking, India today has come up many notches and is sitting at the 26th spot.

IoT technology to boost T&D efficiency
Even as India battles demand and supply mismatches in power, transmission and distribution (T&D) losses continue to be the highest globally. While some estimates put T&D losses at around 20%, others peg this as high as 27%. Either figure is too high, particularly when the Centre has ambitious power production targets and plans to ensure power for all by 2019. Most losses are either due to inadequate infrastructure and technical inefficiency that triggers higher losses or result from theft. The latter occurs when power is pilfered directly from power lines or by bribing officials during meter readings, while others tamper meters to minimize billing. Lessons from the EU Whatever the cause, it is possible to curb such power losses via Smart Grids and the use of IoT (Internet of Things) technology. That such solutions are workable can be gauged from the European Union, where yearly T&D losses only average 6%, ||www.electricalmirror.net||
yet represent an annual wastage of 7 billion Euros. EU power distributors are therefore mandated by new regulations to enhance efficiency across networks, while integrating alternate energy generation and electric vehicles into their grids. If IoT technology and Smart Grids can offer solutions to address 6% T&D losses in the EU, the impact can well be imagined if these are deployed to combat India’s 20%-plus T&D losses. Indeed, with smart technology, it’s possible to plan, measure and boost T&D efficiency. This can be done by installing equipment and software that monitors and communicates across the distribution path. It is then important to use the right strategies via the IoT and associated smart technologies to achieve the goal of minimal power losses. Consider active strategies to control energy losses. Active energy efficiency denotes reduction in energy consumption via measurement, monitoring and controlled usage. Dynamic network reconfiguration and voltage optimization are prime examples. By deploying these strategies, power utilities can solve some of their problems. Examples of three issues and their relevant strategies will help better understand how this can be done. In issue one, technical losses in MV (medium voltage) networks account for around 3% of distributed energy, denoting a major loss. In strategy one, by the use of algorithms, an Advanced Distribution Management System optimizes network configuration, relieves overburdened network segments and helps minimize losses and load unbalance in high and medium voltage substation transformers and feeders. Besides, this helps power utilities reach an optimal voltage profile and enhance voltage quality. In issue two, distributed energy resources – distributed generators (renewable or backup), controllable loads used for demand response and energy storage (electrical or thermal) – can produce rising and falling voltage simultaneously in different parts of the grid. Additionally, mandatory monitoring of this voltage in older substations can be costly and complex. In strategy two, power utilities can tweak the voltage control infrastructure. To procure accurate, real-time voltage data, cost effective, self-powered, communicating IoT voltage sensors at the MV/LV substation level or along lines can be installed by the utilities. ‘Virtual’ sensors can also be used to estimate MV output based on easily accessible data. Also, power utilities can install actuators with smart transformers along MV lines to hike or lower the voltage. Issue three relates to estimates that indicate 90% of non-technical losses take place in LV (low voltage) networks. Assessing improvements would mean identifying and monitoring the losses. Given the high number of points, however, this is expensive. In strategy three, the utilities can use Smart meters, which could work as additional sensors in tracking network energy performance data. Comparing the pattern of measured energy on an LV feeder to
the patterns of energies delivered by smart meters pinpoints the exact location of losses as well as helps in faster detection and location of the LV network outages for improved reliability.
Smart Grid Roadmap
Nonetheless, using IoT and connected technology strategies won’t be easy without understanding how to do so, step by step. Essentially, there are four major steps to distribution network efficiency. The first point to remember is that utilities cannot rely upon outdated technology in the Smart Grid era. With the IoT and allied technologies already a global reality, utilities can upgrade their present infrastructure to overcome numerous modern distribution network challenges. It is important that power utilities in India undertake the above measures to drive higher operational efficiencies. While these steps may inflate short-term capital costs, the long-term advantages – such as lower operating expenses, reduced energy wastage as well as a more integrated and flexible network – are well worth the early investments. IoT network deployed for smart meters must be leveraged for other low throughput, low power applications such as Distribution Automation, Home/ Building Automation, Demand Response, Street Light Automation, etc. India has one of the most complex electricity grid and has benefitted from one of the world’s largest PMUs deployment thereby reducing the threat and scope of blackouts.
Challenge: High electricity theft; Low billing
efficiency; High human errors; Inability to perform real time energy accounting; Increasing tariff; Low customer satisfaction; Lack of granular data; Steady state data from EMS/SCADA is insufficient; Inability to prevent cascaded failures leading to blackouts; Reduced grid stability; Low transmission line capacity utilization; Lack of sufficient RF spectrum for interplay between smart grids and smart cities; Lack of successfully implemented innovative business models in power sector; Absence of guidelines on cyber security for IoT devices deployed in power sector; Lack of understanding of majority of utilities about core aspects of IoT; Absence of IPv6-based last mile connectivity demonstrations in power sector; Absence of harmonization between smart grids and smart cities from an IoT perspective; Absence of interoperability in IoT devices in power sector.
Solution: Remote reading of consumption data and
events; Remote control of electricity supply to premises; Time of Use tariffs for managing peak demand; Capability to switch from post-paid to pre-paid; IPv6 mandated for smart meters; Low-CAPEX business models to reduce financial strain; Revenue sharing business models for a win-win situation for DISCOM, Industry, Customer; Analytics: Consumption Patterns, Load Forecasting, Infra Investment, Outage Detection, Voltage Anomalies etc; Granular data (10s

Grid expansion for the sake of renewables
India is running the world’s largest renewable energy expansion programme with a target to increase overall renewable capacity by more than 5 times from 38 GW in 2016 to 175 GW in 2022.Integration of large amount of fluctuating RE in the grid is a serious technical challenge for grid managers to ensure smooth operations of the Indian grid – the fifth largest in the world. General Network Access (GNA) could be a framework for providing stability in the uncertain situation prevalent today since generation has been delicensed in the Electricity Act 2003 giving rise to an unwanted situation due to the inability of any central agency in planning transmission capacity addition resulting in stranded generation and transmission assets. GNA will put the onus on generators and DISCOMs to apply for GNA and pay a periodic fee for the same. Since the grid will be a plug and play grid it will be able to absorb the infirm with the firm power, demand and supply curves effortlessly. This will happen due to the advantages of the varying demand patterns across the region due to weather and other reasons whereby surplus power cannot only be absorbed within the country but also be exported to the Central, South and South Eastern region. As per the CERC Committee report, “GNA based development of transmission system, on the other hand, is not linked to PPAs. Development of transmission system under GNA would be based on (a) anticipated generation and demand scenario (b) Withdrawal GNA representing the quantum of power each STU/Bulk Consumer anticipates to draw from the ISTS (c) Injection GNA and (d) the long term PPAs already in place.” “This would address the problems being faced presently on account of generators not seeking LTA or seeking LTA for a quantum much less than Installed Capacity and would also get requisite participation of and contribution from the Withdrawal DICs, who are in best position to project their drawal requirements, as part of the transmission planning process.” As per the committee, “GNA based transmission planning, probability of inadequacy of ISTS is expected to reduce substantially in next 4 to 5 years after the transmission system commensurate with GNA based planning is in place. Needless to mention that proper assessment of Withdrawal GNA would go a long way in setting up ISTS of requisite capacity.” The current CERC regulations require generators to identify the target region and a long-term consumer with duly executed power purchase agreement before using the grid through long term access: The generator needs to identify the target region where it intends to sell the power before securing long term access to the grid, The generator also needs to execute a long-term Power Purchase Agreement (PPA) to transmit power by using the long-term access. GNA could be the framework for providing long term access and usage of the ||www.electricalmirror.net||
national grid, which will replace the CERC regulations of long-term Connectivity (2009) and long-term Open Access (2004) and allow plug and play flexibility to the generators and consumers. The issue of green corridors and their interconnections with the main grid, the backing down of thermal power in favour of renewable to access limited transmission grids are all under consideration and the government along with the Ministries seem to be upbeat andoptimistic in coming out with sustainable solutions.
Enhancing downstream efficiencies
Interventions are required on both transmission and distribution end by the government. Transmission Streamline private participation in transmission grid: Enhance transparency in project award through competitive tariff based bidding process. Streamline approval process for exclusive transmission lines of generators and support in obtaining “right of way”. Aggressively extend national grid reach and improve quality: Establish/strengthen grid connectivity to remote locations eg. North East (Hydro); interiors of western region (Solar and wind). Continue strengthening grid quality through higher voltage network. Extend flexibilities in BPTA tenures, supported by similar reforms in PPA: Provide easy access to flexible “single/multi-year” BPTA contracts to fuel market innovation at generator’s ||www.electricalmirror.net||
end. Support the same with similar reforms in PPA tenure Distribution Define a time-bound discom reform plan: Set out the plan for privatization or franchising of all poorly performing discoms, in a time-bound manner. Accelerate implementation of open access to distribution networks across states: Provide seamless access to bulk & gradually non bulk customers directly from generators. Reform power subsidy mechanism for the agriculture sector: Provide for subsidies to the sector under state budgets rather than loading costs to the discoms. Aggressively support agricultural feeder separation across states through central interventions.
Measures for reducing technical losses
Identification of the weakest areas in the distribution system and strengthening /improving them so as to draw the maximum benefits of the limited resources. Reducing the length of LT lines by relocation of distribution sub stations/ installations of additional distribution transformers (DTs). n Installation of lower capacity distribution transformers at each consumer premises instead of cluster formation and substitution of DTs with those having lower no load losses such as amorphous core transformers. n Installation of shunt capacitors for improvement of power factor. Mapping of complete primary and secondary distribution system clearly depicting the various parameters such as conductor size line lengths
etc. n Compilation of data regarding existing loads, operating conditions, forecast of expected loads etc. n Carrying out detailed distribution system studies considering the expected load development during the next 8-10 years. n Preparation of long-term plans for phased strengthening and improvement of the distribution systems along with associated transmission system. n Estimation of the financial requirements for implementation of the different phases of system improvement works. n Formulation of comprehensive system improvement schemes with detailed investment program so as to meet system requirement for first 5 years period.
Measures for reducing non-technical losses
Set up vigilance squads to check and prevent pilferage of energy. n Severe penalties may be imposed on those tampering with the meter seals etc. n Energy audits should be introduced and personal responsibility should be fixed on the district officers (executive engineers) for energy received and energy sales in each area. n Installation of tamper-proof meter boxes and use of tamper-proof numbered seals. n Providing adequate meter testing facilities. A time bound program should be chalked out for checking the meters, and replacement of defective meters with tested meters.

CASE STORY - Energy
Danish CHP station Vattenfall / Fynsvaerket achieved stable temperature signal surveillance in the boiler room – also at 60˚C. The members of the maintenance team at Fyn Power Station were fed up getting error messages and false system alarms from one of the boiler’s temperature surveillance systems. The problem occurred when the ambient temperature approached 60 ˚C. The solution to the problem did not seem straight-forward, but after a talk with one of our sales engineers they decided to do a test set-up with PR 3111 isolated TC converters – and that solved the problem … also at 60 ˚C . Fyn Power Station generates electricity for the Nordic electricity market and supplies heat to more than 85,000 to Danish households and industries, including horticultural greenhouses. Today the station is owned by Vattenfall, one of Europe’s largest electricity producers. System errors and false alarms in connection with ambient temperature fluctuations The station used to get false system alarms and error messages from one of the boilers temperature surveillance systems. The problem occurred when the ambient temperature hit 60 ˚C in the boiler room, which often happened in summer. False alarms and false error messages from the boiler room surveillance system used to be a re-occurring problem… especially during the summer,.The team at Fyn Power Station installed PR TC converter test set up. The test set-up delivered stable system monitoring from day one.The PR 3111 converters were designed to operate within a temperature range of -25 ˚C to +70 ˚C. To test their ability to solve the problem, twelve 3111 TC converters were installed in the panel ‑ a cost-efficient solution that delivered stable system monitoring from day one.

AEF High-Voltage Connections: HARTING Offers Ideal Solution for the Agricultural Sector
roduct Info
Electrification of agricultural machinery becoming ever more important / New technology slated to be presented at AGRITECHNICA in Hanover
The electrification of farm machinery and tractors is becoming increasingly important in the agricultural sector.
The electrification of agricultural machinery and auxiliary components is becoming increasingly important also in the agricultural sector. As a result, HARTING has for several years focused its innovative efforts on the development of a standardised interface between tractor and attachment. The resulting newly developed AEF high-voltage connections are slated to be presented at the AGRITECHNICA trade fair (November 12-18, 2017 in Hanover) deployed in various applications. The connector transmits data and power, and was developed within the AEF (Agricultural Industry Electronics Foundation) in cooperation with all major agricultural machinery manufacturers. "The AEF high-voltage connections are a new technology," explains Guido Selhorst, Head of Corporate Market Communication at HARTING. To date, the agricultural industry has relied on hydraulic or mechanical solutions for power transmission, says Selhorst. But the electrification
of agricultural machinery and attachments is becoming increasingly important to farmers since it can significantly increase productivity. Among others, the use of electric motors is the basic prerequisite for the implementation of complex movement tasks and speed changes in attached equipment. The AEF high-voltage connections are designed to meet the future power requirements of ancillary equipment and attachments. "The HARTING high-voltage connection supports the development of fully electric and hybrid drive systems on the tractor and the increasing demand for electric drives on attachments," explains Selhorst. The AGRITECHNIKA trade show will see the AEF High Voltage Connector presented at AGCO/Fendt (Hall 20, Stand A26), at Sensor-Technik-Wiedemann (Hall 15, Stand F49), at ZF Friedrichshafen AG (Hall 15, Stand C06) and at AEF (Hall 15, Stand F33), at the respective exhibition stands.

It will also look into the issue of the selection of the site for the plant, for which the chief minister has suggested a location near Ropar, in place of the existing 35-year old thermal plant which had outlived
its utility," the release said The company has offered to set up the plant anywhere in the state to ensure uninterrupted and cheap power to the industry, but preferably in a region with an existing pipeline network The company also expressed the desire to associate with state government for setting up gas power plants at the load centers at Ludhiana and Amritsar, either on Independent Power Producer (IPP) or Engineering Procurement Construction (EPC) model The chief minister felt the proposed gas plant would give a fillip to the state government's plan to develop Kandi region as an industrial zone, along with the foothills of Shivalik The high-powered GE delegation, led by Nanda, earlier made a detailed presentation to the chief minister on its proposal. Pointing out that gas power plants had emerged as an effective, green alternative to the conventional coal-based ones, Nanda said the former were also more economically viable as they required up to 35 acres less land Further, gas based power plants required just 20 months for completion as compared to at least 48 months in case of thermal plants, which also makes these projects cost effective, he added
