EDITOR'S DESK Dear Reader!

Indian

electrical equipment sector is growing in drastic way according to the experts shown the factor responsible the desire growth is cable Switchgear market.

As control panels is a part of Indian power sector growth participating in huge way for electricity distribution. But in a few years we are coming up with the high demand in touch screen control panels.

Significant electricity capacity additions supported by government investments will drive demand for switchgear and controlgear. Largescale planned investments and installed capacity addition of 220 GW during (FY16-22) will drive demand for switchgear & control gears in India to USD8.2 billion by FY'22.

The writer provide the facts which show the potential, modernization, drawbacks and various opportunities coming in the power generated system.

The LED Lighting market in India has been growing over 50% for the last 5 years (2009-10 to 2013-14) and expected to sustain this growth rate in the next five year (2014-15 to 2018-19).

Although late, the GoI has announced a lot of incentives and measures in order to prioritize LED manufacturing in the country.

Govt to Organise Quality Conference With Coal Firms: Power Minister Piyush Goyal

The government will organise a Quality Conference with coal companies to ensure the right quality of the fossil fuel is supplied to power plants, Power Minister Piyush Goyal said.

"On April 5, the Ministry is holding a Quality Conference with all the coal companies and technical experts of the sector to sit down and lay down the strategy to ensure that right quality of coal is supplied to our power plants and help them achieve higher efficiency rates," Goyal said at an event.

He also said the Cabinet recently approved a more liberalised pricing policy on coal-bed methane development and production, which will ensure more efficient usage of coal with evolution of technology.

This will define the manner in which India uses its coal in the future, he said.

The minister noted that there is no problem in the

sector to which a solution cannot be found.

"A problem is a problem till its solution is found out. The power sector needs a lot of innovation and improvement to make India power self-reliant in the future," he said.

Goyal discussed three key areas which have shown tremendous transformation in the last three years -- coal sector, solar power and the UDAY scheme.

He said the country has seen a huge ramp up in production of domestic coal in the last three years,

India, China host Business and Investment Forum in Zhenjiang India and China jointly organised a Business and Investment Forum in Zhenjiang to introduce Chinese investors with opportunities available in India in sectors like renewable energy, smart cities, power sector, urban transportation and infrastructure as part of the Make in India initiative. Consulate General of India in Shanghai, Prakash Gupta, along with Zhenjiang Municipal People’s Government had jointly organized an IndiaChina (Zhenjiang) Business and Investment Forum in Zhenjiang earlier on March 17.

A delegation of 30 plus Indian companies comprising CEO’s of Larsen & Toubro, TCS, Reliance, Adani Group, CII, Sterlite, Jet Airways, Tech Mahindra, along with Legal consulting and Business Advisory Firms like HSA legal, Link legal Law Firms and Banks like UBI, Canara and Axis made presentations on sectors like Infrastructure, Banking, IT, Urban Transportation and legal guidelines for setting up businesses in 10

India, according to a statement. During the forum, a new website – CHINDIA360 (www. chindia360.com) – was also jointly unveiled

by Executive Vice Mayor and the Consul General. The website has been designed by one of the participating Indian companies and is aimed at providing all necessary info to potential China investors, who are looking for investment opportunities in India’s growing market, by providing a updated and timely information on investment guidelines, and offering comprehensive solutions to potential investors in India.

A series of B2B meetings were also held between participating Indian companies with their Chinese counterparts from Zhenjiang, which generated significant business leads for the participating companies. In addition, in the field of educational exchanges an MoU on Project Cooperation, was also signed between Jiangsu University and Kalinga Institute of Information Technology (KIIT) University.

to the tune of more than 100 MT. However, he added that this year the quantity of coal produced has been less compared to the previous two years.

The minister stated that though the country has the ability to produce more coal, it is held back by market forces.

This means that for several years to come, India will have sufficient coal and imports would not ramp up as it did three years ago, he added.

Goyal said the country has abundant coal reserves and domestic production capacity, yet power plants are dependent on imported coal. This is because a major portion of our thermal power plants cannot use more than 30 per cent of domestic coal, he added.

Goyal said the government is tirelessly working to increase the ratio of domestic coal being used in our power plants by improving technology.

PFC Provides Rs 2,703 Cr to Wb's First Supercritical Project "PFC, a Non-Banking Financial Company (NBFC) in power sector, has sanctioned a term loan of Rs 2,703.88 Cr to West Bengal Power Development Corporation Ltd (WBPDCL) for construction of Unit 5 (1X660 MW) under phase III of Sagardighi Thermal Power Station in Murshidabad," the company said in statement.

According to the statement, WBPDCL is a company owned by the West Bengal government for generation and supply of electric power in the state.

The 660 MW Sagardighi Unit 5 is the first supercritical thermal power plant being developed by WBPDCL in the state, which is expected to be commissioned by Oct’20 at an estimated cost of Rs 3,862.69 Cr. It will generate approximately 4,209 MUs of energy to meet the future power requirement of West Bengal.

The project is proposed to be funded in the debt equity ratio of 70:30 and the entire debt is proposed to be funded by PFC, it said. The loan agreement was signed between PFC and WBPDCL officials in Kolkata.

State government officials and utilities and senior management of PFC were also present during the signing of the agreement, it added. PFC has a long standing relationship with WBPDCL and has sanctioned loans worth Rs 8,290 Cr for various existing units of Kolaghat, Sagardighi, Santaldih and Bakreswar thermal power projects. ||www.electricalmirror.net||

Joint Venture Between Sembcorp Utilities and Bangladesh IFC (International Finance Corporation), a member of the World Bank Group, has roped in Japanese agency JICA to invest $30 million in Sembcorp North-West Power Company Ltd. Sembcorp North-West Power Company Ltd is a joint venture between Sembcorp Utilities and Bangladesh government owned North-West Power Generation Company Ltd. It is building a 414MW dual-fuel combined-cycle power plant at Sirajganj in Bangladesh. The plant will significantly expand power-generation capacity in Bangladesh.

JICA's $30 million is part of the total financing package of $ 165 million that includes a loan from IFC’s own account as well as additional loans mobilised through partners. The total project cost is estimated at around $412 million.

"The project is expected to be one of the most efficient plants in the country that will help modernize Bangladesh's power sector," JICA's senior vice-president Kenichi Tomiyoshi said in a statement.

This transaction is IFC's first co-investment with JICA since the two organizations signed a master cooperation agreement in April 2015.

Tang Kin Fei, group president and CEO, Sembcorp Industries, said, "Sembcorp's commitment towards supporting Bangladesh's vision for continued growth and development is further strengthened with support from JICA, IFC, and other global investors. Sembcorp's Sirajganj power plant will provide cost-effective and reliable energy solutions to the country for more than 22.5 years after its completion.”

"Bangladesh is on an ambitious growth path.

Addressing the electricity gap is an immediate need.

With JICA’s first investment into the country, IFC is confident of making a positive impact on the economy and the quality of life of Bangladeshi people. The project will help address the electricity gap while lowering the cost of generation," said Hyun-Chan

Cho, IFC's Asia-Pacific Head for Infrastructure.

Nearly 40% of Bangladesh’s 160 million population live without access to electricity. Citizens encounter frequent blackouts. Severe power shortages are a major bottleneck for the growth of the job-creating manufacturing sector, hampering economic growth and poverty-alleviation efforts.

The power plant will be the second largest power plant in the country and represents the largest foreign direct investment into this sector in recent years. The success of the project will demonstrate the profitability and sustainability of public and private-sector partnerships in Bangladesh’s power sector to international players, helping attract additional capital to the sector.

IFC promotes sustainable growth and private-sector development in Bangladesh by investing in critical infrastructure, boosting financial inclusion, enhancing textiles competitiveness, and supporting reforms to make doing business easier for the private sector.

IFC committed $635 million in Bangladesh, in own and mobilized funds across 13 projects, for the fiscal year ended June 30, 2016. IFC’s committed portfolio in Bangladesh is about $1 billion in 47 projects.

Oil Field Leases Extends for Oil Companies by 4 Years Expiry

The government will extend the lease for oil or gas fields four years before the initial 20-year term expires, failing which an extension plea would be deemed to have been rejected, says a draft proposal on the new exploration policy aimed at eliminating extension uncertainties faced by contractors.

Billionaire Anil Agarwal-owned Cairn India has been ||www.electricalmirror.net||

lobbying the government for years to extend the contract to operate the oil and gas block in Barmer, Rajasthan, by 10 years after the initial 20-year agreement runs out in 2020.

Cairn contributes nearly 30% of India’s domestic output and has urged the court for more than a year to direct the government to quickly decide on an extension.

The draft rules, when formalised, will not apply to the Barmer block but will end the kind of uncertainty Cairn faces today for blocks awarded under the new exploration policy.

According to the draft contract under the new Hydrocarbon Exploration and Licensing Policy (HELP), the lease has to be granted for an initial period of 20 years, which can be extended by mutual agreement between the government and contractors for “five

years or beyond as may be mutually agreed, or as per extant government policies.” The previous policy provided for an extension of five years for an oilfield and 10 years for a gas field, or such period as was mutually agreed upon.

The draft contract, open to stake holder consultation, requires the contractor to submit a request for extension ‘no later than 5 years before the expiry of the existing contract’. “The Government reserves the right to approve the request for extension no later than 4 years before the expiry of the existing contract. If not approved within the stipulated time, such a request would be deemed to be rejected,” as per the draft contract.

Last year, the government had announced a policy on extension of the so-called Pre-NELP ‘discovered’ fields, or 28 small, medium sized fields discovered

by Oil and natural Gas Corp (ONGC) and Oil India Ltd and awarded to private joint ventures between 1994 and 1998. The policy, most importantly, required the government share of profit to increase by ten percentage point during the period of extension.

India Ratings Maintains Negative Outlook on Infra Sector in Fy-18

Fitch Group's India Ratings and Research agency maintained a negative outlook on the infra sector for the FY-18 with varied outlooks on the individual sectors. Toll roads, thermal and wind power continued to pull the overall sector outlook down with the ratings agency predicting a further two per cent fall in plant load factor of thermal power capacity. Also, the agency

sees an absence of capacity addition in wind power going forward, owing to the grid parity in pricing being achieved by the solar sector and the surplus power situation in major states. The ratings agency in feb released a special report with its outlook on infrastructure and project finance for the next financial year. Among the individual sectors, the negative rating

was continued for the third consecutive year for toll roads and thermal power, while the outlook for wind energy turned negative from a stable rating in the last two years. The ratings agency has changed its outlook for airports to positive from stable while maintaining a stable outlook for seaports for the third consecutive year.

Renewables Grew 34%, Coal 9% in India in 2016 While the US saw domination of renewable energy technologies in its new capacity addition in 2016, India had an impressive milestone of its own last year. Capacity addition in India’s renewable energy sector increased by 34% compared to 9% in the coal-based power sector in 2016. Interestingly, growth in the coal-based power sector is relatively in-sync with the economic growth of the country, while growth in the renewable energy sector surpassed it by more than 4 times. The overall growth rate in the thermal power sector (includes coal, diesel, and gas) was lower at 8%, with capacity contraction in the diesel sector. There was no growth in the nuclear power sector and around 1% growth in the large-hydro power sector (projects with more than 25 megawatts of capacity). Within the renewable energy sector, solar power grew by 107%

with an addition power sector, the absolute capacity added in the of more than renewable energy sector was slightly lower than 4,600 megawatts. that in the coal sector. Nonetheless, this situation Bio-energy also could soon be reversed as the Indian government grew by an has very ambitious solar capacity addition targets. A impressive 78% total of 29,802 megawatts of new power generation but it was demoted capacity was added to India’s grid last year. More to the third-largest than 53%, or 15,950 megawatts, of this came from renewable energy technology last year when solar the coal-based power sector . power surpassed it. Wind energy remained the largest renewable energy technology in India India, China Should Jointly Bid for Oil, and grew by 18%.

42% Of India’s New Gas Fields Power Capacity Came From Renewables in China and India "can jointly bid for contracts to acquire and develop overseas oil 2016. While in rate of and gas resources," an article in the state-run Global Times said. Compared with growth of renewables international oil giants, Chinese and Indian oil companies are still behind in terms was almost 4 times of management, technology and capital strength. Cooperation between Chinese that of the coal-based and Indian firms would allow them to gain bargaining power in negotiations

Coal-Based Power Generation Rises 6 Pc in India The coal-based power generation increased by 6% to 674.4 BUs during the Apr-Dec period of the ongoing fiscal. “During the period, the coal-based power generation grew by 6.18% to 674.492 BU as compared to the same period in the previous year,” Power and Coal Minister Piyush Goyal said in a written reply to Rajya Sabha. The dispatch of coal by state-owned CIL to power sector in Oct last year was at 31.91 MT as against 34.50 MT during the same month in 2015, the minister said. Keeping this in view, the decline can be attributed primarily to regulated lifted by power plants which preferred to consume from their stocks apart from heavy rains in coalfields in Aug’16 and Sep’16,” the minister said. Coal India (CIL) which supplies majority of its coal to the power sector is eyeing 598.6 MT of production in the ongoing fiscal. In 2015-16 the CIL’s output was at 538.7 MT. In 2013-14 the CIL’s output was at 462.4 MT and in 2014-15 it was 494.2 MT. There is a continuous annual growth in coal output by CIL, the minister said.

in the international oil and gas market," it said. It also proposed that China and India could strengthen cooperation in investments in energy technology and products. China's advanced solar energy technologies and the low cost of its solar energy equipment can help India has abundant solar energy resources. It said the two countries can jointly invest in the solar photovoltaic industry through joint ventures and technology transfer to expand their solar energy market. The two countries can jointly develop and invest in power generation projects. It said another area for energy cooperation is pushing ahead with construction of oil and gas pipelines. Both China and India need reliable transmission pipelines as they import oil and gas from Russia, Central Asia and the Middle East. China has built a gas and oil pipeline network which connects with its neighbouring countries to the north and west. India is also working to build multiple energy pipeline routes but has experienced some difficulties due to the conflict between India and Pakistan. India urgently needs China to join in its effort to build the pipeline network. Meanwhile, overland transportation routes that China expects to build to its west and southwest cannot bypass South Asian countries. India's prominent role in South Asia makes it even more necessary for China to cooperate with the country in building overland energy routes," it said. ||www.electricalmirror.net||

Govt Plans to Auction Stressed Assets to Reduce Banks’ Npas

In order to reduce the non-performing assets (NPAs) in the economy, the govt is working on plans to bring together major state-owned banks to conduct a large-scale public auction of stressed assets, especially in the steel and power sectors, government sources said. As per the proposal being worked out by the finance ministry in consultation with the banks, the govt is keen on cash-rich public sector firms buying a portion of the mortgaged assets within their sector that may be put up for sale by the PSU banks.

The Centre is keen to involve state governments as well. Sources said the finance ministry is in favour of PSUs operating in the steel and power sectors bidding for assets put up for sale by the banks

that may be useful for them. Such acquisitions are expected to be a win-win for both state-owned banks as well as PSUs. While it will help banks clear a part of their bad debts, the acquisition of assets at market-determined prices during an auction will help in expansion of PSUs operating in the sector.

The proportion of bad loans has been rising, despite the govt having announced the Indradhanush plan of reforms for PSBs. Scheduled commercial banks total stressed assets, which comprise gross NPAs as well as restructured standard advances, were much higher at Rs 9.64 Lakh Cr as on Dec 31, 2016, as per the finance ministry data. Bad debts have risen sharply in the PSBs, while private banks registered

somewhat lower jump in NPAs in the nine months in the current fiscal so far. Public sector banks NPAs surged by over Rs 1 Lakh Cr during Apr-Dec period of 2016-17. PSU banks’ gross NPAs in the first nine months of current fiscal rose to Rs 6.06 Lakh Cr by Dec 31, 2016, from Rs 5.02 Lakh Cr during the entire year of 2015-16. For the private sector banks, gross NPAs grew to Rs 70,321 Cr by Dec 31, 2016, from Rs 48,380 Cr as on Mar 31, 2016. During the meeting on NPAs, members of the Parliamentary Consultative Committee suggested several measures to deal with the issue.

Wind Power Sector Likely to Move Entirely Towards Auction-Based Allocation: Bridge to India Following the record-breaking success of the recent 1,000 MW wind power auction, the sector is likely to shift entirely towards auction-based allocation route but this transition may lead to short-term hiatus on the market, renewable energy research firm Bridge to India said in a report. “Indian government wants to tender out 4 GW of wind capacity next year but capacity addition through the tendering process often takes a long time. This may lead to a short-term demand hiatus in the market,” it said. Bridge to

India also said remains to be seen if investments in transmission grid can keep up with increases in renewable generation capacity and inter-state flows of power. “Concentrating projects in resource heavy states will also put more strain on the transmission grid. It remains to be seen if investments in grid can keep up with increases in generation capacity and inter-state flows of power,” it said. On the record fall in the wind power tariff, Bridge to India said since the old procurement model had failed that

was hurting the developers, the 1,000 MW tender managed to attract intense competition from bidders.

“Second, the preferential tariff regime was used by some wind turbine manufacturers to bundle together land, turbines and EPC work. This allowed them to command significant price premium and dominate the market. Auctions will provide more transparency to the sector, break wind turbine manufacturers’ domination and make the wind turbine market more efficient,” the report said.

Solar Power Bids Unsustainable: Bridge to India Of India’s installed power generation capacity of 314,642 MW, green energy accounts for 16%, or 50,018 MW. Consulting firm Bridge to India has termed the recent low winning bids for solar power projects in India “unsustainable” and warned that “inadequate risk pricing poses a severe viability challenge for the sector”. The warning comes after solar power developers last month bid as low as Rs 2.97/kWh for a 750 MW project at Rewa in Madhya Pradesh. The winning bid offered a so-called levelized tariff—the value financially equivalent to different annual tariffs over the period of the PPA of around Rs 3.30/unit. In a note titled Bidding behavior in the Indian solar sector not sustainable, Bridge to India 14

APRIL 2017 || ELECTRICAL MIR ROR

noted that India allocated 12.6 GW from July 2015 to Dec’16 to winners through a bid process. The tenders saw tariffs falling from Rs 5.50-6.00/kWh in mid-2015 to Rs 3.29/kWh in 2017. “The average harmonized tariff of Rs 4.31 /kWh gives us an equity IRR of 14.20%, significantly below the benchmark expectation of 18%,” the report said. “This is a clear demonstration of aggressive bidding in the sector and we believe the developers are bridging the gap in two ways. First, by focusing relentlessly on optimization of technical and financial project parameters, they can push up IRR by 200-300 basis points. Second, the developers are making speculative favourable assumptions on future equipment prices,

land sale values, debt refinancing, salvage value, etc., to defend project returns,” the report added.

India’s solar power generation capacity has increased by a third to 10,000 MW from 2,650 MW as of 26 May 2014. “Low equity IRRs suggest that the Indian developers, in particular, are not pricing risks fully and too much faith is being placed on an optimistic future scenario,” the report said. India, the world’s third-largest energy consumer after the US and China, plans to achieve 175 GW of RE capacity by 2022 as part of its global climate change commitments. Of this, 100 GW is to come from solar.

Indian Power Utilities Apr’16-Feb’17 Thermal Coal Imports Fall 20% on Year

Indian power utilities imported 60.38 MMT of thermal coal over Apr’16-Feb’17, down almost 20% year on year, according to data released by the Central Electricity Authority, seen by S&P Global Platts. The April-February imports registered a growth of 10.8% month on month. Of the total quantity, 18.50 MMT was imported by 29 utilities for blending with domestic coal, while 41.88 MMT was imported by 11 utilities for power plants that use only imported coal. 15 utilities did not import any coal during the 11 months

of the ongoing Indian fiscal year, while no data was available for one utility. Private sector power company Adani Power imported the largest volume of thermal coal during the 11 month period at around 14.5 MMT. Tata’s Mundra UMPP followed with around 9.9 MMT. On a monthly basis, February imports stood at 5.63 MMT, falling by around 16% year on year. The government plans to reduce the country’s dependency on imported coal, to facilitate the consumption of the surplus fossil fuel produced by state-run miner Coal

India Limited. CEA has not assigned any targets for power utilities for the current fiscal year. However, they can procure imported coal if they find it to be more economical than using domestic coal, especially for coastal power plants. Power utilities had imported around 80.47 MMT of thermal coal in fiscal 2015-2016 (Apr-Mar), down 11.8% year on year, and below the target of 84 MMT.

With India Visit, Westinghouse CEO Keeps Nuclear Project Alive Westinghouse has told India that it will go ahead with its plan to build six nuclear reactors in Andhra Pradesh in partnership with Larsen & Toubro, despite the recent decision by Toshiba Corp., the US company’s Japanese parent, to quit the business of setting up atomic power stations. Westinghouse conveyed its decision to the Indian government at a recent meeting in Delhi.

Toshiba’s decision mid-Feb to withdraw from its lead role in Westinghouse-led plants due to $6.3-billion write-downs has raised doubts over the US company’s various nuclear projects worldwide, including India.

However, India was not unduly worried by Toshiba Corp.’s write-downs at Westinghouse Electric Company, which the Japanese conglomerate had acquired for $5.4 billion in 2006. Toshiba sought to establish global nuclear power leadership with its purchase of Westinghouse in 2006, and the India-Japan civil nuclear deal concluded in Nov’15 was expected to strengthen the Westinghouse project in the country.

But Toshiba, with business interests in computer chips,

elevators, and nuclear power, ran into trouble over an accounting scandal in 2015, and later because of cost overruns at its US projects. Toshiba will now reportedly withdraw from being a general contractor for the nuclear plants of Westinghouse.

Westinghouse was allotted a site in Andhra Pradesh to set up a nuclear power plant after the India-US civil nuclear deal. Nuclear Power Corporation of India Limited (NPCIL) and Westinghouse are also scheduled to conclude the commercial contract this year, after which the US nuclear firm is to set up six reactors at the proposed plant in Andhra Pradesh. The state will also house the second Russian-made nuclear power project (comprising 6 reactors) after Kudankulam in Tamil Nadu and the announcement of the site could come either before or during Prime Minister Narendra Modi’s trip to St Petersburg scheduled to be held between June 1 & 3. The two sides are currently in the process of identifying a site in Andhra Pradesh

The contracts for Units 5 and 6 of the Kudankulam plant are also expected to be signed in the near future. L&T has been active in India’s nuclear construction sector and in 2009, the Mumbai-based company signed an agreement with Westinghouse to manufacture and sell its AP1000 nuclear reactor that runs on pressurised water technology. The construction major works closely with NPCIL on other power projects. L&T says that it “has been playing a vital role in India’s nuclear power sector over the past five decades, with its expertise and inhouse capabilities to construct critical and complex structures.”

NTPC Eyes Entry in India’s Electric Vehicles Segment Enthused by India’s electric vehicle (EV) market potential, state-owned energy company NTPC Ltd is exploring a new business around it. To start with, India’s largest power generation utility is looking at setting up charging stations to help create the demand for electricity generated by its plants and keep pace with the fast-changing power sector. This comes in the backdrop of ambitious government plans for a mass scale shift to electric vehicles by 2030 so that every vehicle on Indian roads by then-both personal & commercial-are those that are powered by electricity. India’s current installed capacity of 314,642 MW and projects under construction are expected to meet the country’s electricity demand till 2026. This 16

APRIL 2017 || ELECTRICAL MIR ROR

is the trigger for the NTPC to scout for new growth areas. NTPC’s thermal stations are registering a low PLF due to muted demand. According to NTPC, its thermal stations clocked a PLF of 77.72% for the nine months of FY 2016-17 as compared to a national PLF of 59.64%. In addition, NTPC wants to contribute significantly to India’s plans to set up 100 GW of solar power capacity by 2022. The utility wants to supply electricity from 10,000MW of solar power capacity that it is setting up on its own and buy 15,000 MW on behalf of the MNRE.

Us-Based Evergreen Power Raise to $100 Mn for India

News of the month

US-based Evergreen Power is in talks with investors, including private equity, infrastructure funds and strategic investors, to raise up to $100 million in equity to ramp up its wind energy projects in India.

The company wants to bring 280 megawatts (MW) of wind energy online in the next 12 months in the states of Tamil Nadu, Karnataka and Madhya Pradesh.

Eventually, it aims to scale up wind energy production capacity to 1 gigawatts by 2020 by adding 250-350 MW every year.

"We are seeing tremendous interest from serious investors, not just some people testing the waters.

They want to put significant capital to work in India.

India's macro-factors, central government strength is instilling confidence in the investment community," said Surjeet Kumar, co-founder at Evergreen Power.

The company wants to close fundraising in 60-90 days. Kumar said it would also acquire $200 million in debt to build the capacity. Ambit Capital Pvt Ltd, the leading investment bank, is the exclusive financial adviser to Evergreen Power. Evergreen Power was founded in 2012 and has several large wind projects under development.

India has set a target of installing 100 GW of solar capacity and 60 GW of wind capacity by 2022. The renewable energy sector is expanding at a rapid pace as the country looks to meet its commitment made at Paris Climate Change summit.

India has to achieve about 40% cumulative electric power installed capacity from non-fossil fuel based energy resources by 2030. The sector is undergoing consolidation with tariffs falling to record low levels.

In January, renewable energy firm Orient Green Power Co said it is evaluating a merger of its wind power business with IL&FS Wind Energy.

“We are very positive about the renewable sector in

Resume on the Rs 500 Not & Rs1000 No Effects in Transmission Projects The notes pullback had no major impact on power transmission projects as states reported no delay in implementation of these projects to the Central Electricity Authority (CEA), a power ministry official said.

The government announced scrapping of high-value notes on November 8 last year following which there were fears that it would slow the economic growth and implementation of various infrastructure projects as well.

"The CEA has received feedback from states on the subject, which suggests that there has not been any significant impact of demonetisation on the construction activities of the transmission lines and sub-stations," a power ministry official said.

Elaborating, the official said, "In the monthly progress reports of interregional and inter-state transmission schemes published by the CEA for 18

November, December 2016 and January 2017, demonetisation has not been cited as a reason for delay in transmission projects being implemented by PGCIL." About reported difficulties in payment of daily labourers and for hiring of tractors, it may be mentioned that transmission projects involve specialised and skilled workmen. Even the machinery, tools and plants are of specialised nature and usually owned, available on long-term contract by contractors, the official said.

Also, payments to the contractors and contract labourers of PowerGrid are done through the cashless medium.

PowerGrid is taking necessary steps so that even vendors can make payments directly to the bank accounts.

During the period since November 8, 2017, site activities were normal and in fact, Power Grid Corporation completed a number of critical lines and sub-stations, the official added.

India despite pricing pressure. Players are consolidating to attain scale which is very important. Consolidation is a sign of a strong and mature industry. It points at greater investor appetite," said Kumar.

India received $1.77 billion foreign direct investment in non-conventional energy sector from April 2014 to September 2016. It was among the top 10 in the world investing in renewable energy, according to UN Environment Program's (UNEP) 'Global Trends in Renewable Energy Investment 2016' report.

"One of India’s major advantages today and going forward is that its renewable energy potential is vast and largely untapped," according to NITI Aayog, a Government of India policy think-tank.

"The good news also is that costs of generating renewable energy have fallen steeply in the past decade, and once projects are set up, costs are not likely to increase over life of the asset – typically 25 years."

Electrification Drive: REC Averages 30,000 New Connections Per Week

India is in electrification overdrive, with about 30,000 new electricity connections being granted every week. The Union power ministry is mapping the progress live on a website and is also measuring changes in lifestyle in the recently electrified villages, collecting largest data of its kind. NITI Aayog, the Centre’s premier think tank, has advocated that other ministries use this data for other social welfare schemes.

As per the Garv-2 portal, 23,000 new electricity connections were given last week and 41,000 in the previous week. In the ninth week of this calendar year, 28,000 power consumers were taken on board.

State-run Rural Electrification Corporation is targeting to scale up the drive to grant 100,000 connections every week, its executive director Dinesh Arora said. India has never seen electrification at such large scale earlier, and neither have details been made available on electrification at household level. Electrification data was only captured for families below poverty line earlier. The Garv-2 portal was launched on December 20, 2016.

“We expect it to stabilise and accelerate the drive by March 31,” Arora said. Power ministry officials said the Aayog has recommended Garv-2 application be used for sanitation and other social schemes.

In February, 66,000 new customers were registered and in March so far 86,000 new connections have been granted. The new connections are uploaded live on the website with meter and contact details. The government has also kick-started an electrification impact survey on villages that have been electrified for more than six months.

Gujarat, Andhra Pradesh Refusing to Paying More for Wind Power Two of India’s high wind energy potential states have refused to buy wind power at a rate higher than the one arrived at the country’s first ever wind power auction, putting in jeopardy about 500 MW of projects in these states.

The auction, completed in February, had brought wind power tariff down steeply to Rs 3.46 per kwH. But before the auction, power regulators in Andhra Pradesh and Gujarat had set the tariff for 2016-17 at Rs 4.84 per kwH and Rs 4.19 per kwH respectively.

Now, neither of the states is willing to sign power purchase agreements (PPAs) at a tariff higher than Rs 3.46 per kwH. If a Rs 3.46 tariff has been discovered, why should we sign PPAs at a higher tariff?” said Ajay Jain, chairman at Andhra Pradesh Power Generation Corporation.

“This is the tariff that will be paid even by non windy states. Why should Andhra Pradesh, which has strong winds, pay more?”

The decision has put at risk projects of around 500 MW in these states. These projects have been completed but have still to sign PPAs with their respective power distribution companies (discoms). These projects had

been financed and built on the premise that the tariff would be much higher.

Cost of wind power production depends on numerous factors, such as wind speed at the location of the project, height of wind tower used, etc, which vary considerably from state to state.

The terms of the auction allow the winning developers open source access, by which they can sell the power produced to states other than the one where their project is located. Andhra Pradesh’s discom has filed a petition before the Andhra Pradesh Electricity Regulatory Commission, putting forward Jain’s argument and seeking a direction.

Only nine states in the country, including Andhra Pradesh and Gujarat, have wind speeds high enough to produce wind power. All of them so far had feed-in tariffs ranging between Rs 4 and Rs 6 per kwH. In Gujarat, the Gujarat Electricity Regulatory Commission (GERC) has already taken the initiative.

In a letter dated March 17 to the 12 discoms in the state, Roopwant Singh, secretary at GERC, has directed that both wind and solar power should henceforth be procured

through competitive bidding.

The central and various state governments have initiated the competitive bidding process for procurement of power from wind and solar energy projects, in which the discovered tariff for solar and wind energy projects has shown a substantial reduction, the letter said.

“In view of the above, the commission directs that distribution licensees may procure electricity from wind and solar projects through competitive bidding,” Singh had said in the letter. “The tariff determined by the commission in the respective category of renewable energy will act as a ceiling tariff.”

A wind power developer, who did not want to be named, said there is no problem with solar projects where all concerned central and state government agencies have been following the auction process for years. “But wind is a different matter. We made our calculations of returns based on certain assumptions, which will now go haywire. Definitely, this is not what developers want,” this person said.

Government Asks State Oil Firms to Present Integration Plan

State oil firms have been asked to present a plan for integration, which should happen in 2017-18, Oil Minister Dharmendra Pradhan has said.

In his budget speech two month ago, Finance Minister Arun Jaitley announced the plan to restructure state oil firms to create an integrated ‘oil major’ but didn't give much detail.

The Oil Ministry has now asked state firms to prepare a plan for the merger, Pradhan said. The Oil Ministry and the Department of Investment and Public Asset Management will oversee the process of integration, he said.

On whether the government planned to sell its shares in Hindustan Petroleum (HPCL) to Oil and Natural Gas Corp (ONGC), Pradhan said, "There is nothing in front of me." He said the progress will be made only after companies submit their plan Separately, Pradhan said he did not rule out the possibility of India joining China, Japan and Korea in jointly buying liquefied natural gas (LNG) to extract better deals. China, Japan and Korea have recently agreed to cooperate on jointly purchasing LNG and sharing related information.

The power is gradually shifting from oil and gas producers to consumers, Pradhan said.

A supply glut in the past three years has pummeled oil and gas prices and given heavy consumers like India better bargaining power.

A three-member arbitration panel has started hearing validity of the government's demand of USD 1.55 billion as compensation from Reliance Industries for "unfairly" producing ONG’s gas.

The panel, headed by Singapore-based arbitrator Prof Lawrence Boo, had its first hearing on March 3 where the timetable was drawn, sources privy to the development said.

RIL will first file its statement of claim, followed by a statement of defence by the government. This will be followed by rejoinders, counter-rejoinders and oral hearing, sources said, adding that the panel plans to wind up the hearing in a year.

The central government has named former Supreme Court judge G S Singhvi as its nominee on the threemember arbitration panel while RIL and its partners BP Plc of the UK and Canada's Niko Resources have named former UK High Court Judge Bernard Eder to the panel.

RIL-BP-Niko had slapped an arbitration notice on November 11 last year.

This was against the oil ministry's November 3, 2016

Arbitration on Compensation Demand in RILONGC Row Starts notice to RIL, Niko and UK's BP seeking USD 1.47 billion for producing about 338.332 million British thermal units of gas in the seven years ended March 31, 2016 that had seeped or migrated from the Oil and Natural Gas Corporation's (ONGC) blocks into their adjoining KG-D6 in the Bay of Bengal.

After deducting USD 71.71 million royalty paid on the gas produced and adding an interest at the rate of Libor plus 2 per cent, totalling USD 149.86 million, a total demand of USD 1.55 billion was made on RIL, BP and Niko.

RIL is the operator of the KG-D6 block with 60 per cent interest while BP holds 30 per cent. The remaining 10 per cent is with Niko Resources.

The government's compensation claim flowed from the report of the Justice (retd) A P Shah Committee.

The Shah panel, in its August 28, 2016, report, concluded that there has been "unjust enrichment" to the contractor of the block KG-DWN-98/3 (KG-D6) due to production of the migrated gas from ONGC's blocks KG-DWN-98/2 and Godavari PML. The government, sources said, accepted the

LEDs Reduces Co2 By 80 Million Tonnes in A Year, Saving Rs 40,000 Crore in Power Bills The government's promotion of light emitting diodes (LED) will help reduce carbon dioxide emissions by 80 million tonnes per annum and save around Rs 40,000 crore in power bills annually, Power Minister Piyush Goyal confirmed.

"The LED project, where the government is replacing the lighting load of the country with LEDs, will reduce carbon dioxide emissions by 80 million tonnes per annum and the economically prudent project will help the consumer save around Rs 40,000 crore annually in electricity bills," Goyal told the World Conference on Environment 2017 here.

Similarly, India is trying to move from a highly thermal power generation dependent economy towards renewable energy, he said.

"The solar power programme has been scaled up from a 20 gigawatt (GW) target to 100 GW by 2022. All the renewable sources, including large hydro projects, taken together, India has set sights on on 225 GW of renewable and clean energy by 2022," he added.

Referring to the government's aim of converting all vehicles to electric vehicles, Goyal said Prime Minister Narendra Modi had directed a group of senior ministers 20

APRIL 2017 || ELECTRICAL MIR ROR

to lead the initiative to ensure that most vehicles in India, if not all, were powered by electricity latest by 2030.

"The conversion of India's vehicles into electrical ones has the potential to save fossil fuel worth about $100 billion annually and reduce pollution in cities by 80-90 per cent," the minister said.

He said that according to a government study, India can power its entire vehicular traffic in 2030 on solar power by using only 1 per cent of the land area of Rajasthan.

Holding humankind squarely responsible for climate challenge, Goyal cited Mahatma Gandhi's 1911 phrase - "economy of nature" - to say that only human beings themselves can address the issue.

"The Earth provides enough for every man's need, but not for every man's greed," he quoted Gandhi as saying.

"It is time human beings understood that climate change is a challenge caused by humans only and ultimately it is humans who can address it.

"We are living on this planet and using its resources as if we have another planet to go to later," he said.

The largest loss experienced due to climate change is by the poorest and the underprivileged, the minister added.

recommendations of the committee and consequently, decided to claim restitution from RIL-BP-Niko for "the unjust benefit received and unfairly retained".

So, a notice was sent, they said, adding that the government is also pressing RIL to pay USD 174.9 million of additional profit petroleum after certain costs were disallowed because of KG-D6 output being lower than the target.

The cost recovery issue is being arbitrated separately.

Originally, ONGC had sued RIL for producing gas that had migrated from its blocks KG-DWN-98/2 (KG-D5) and Godavari PML in the KG basin to adjoining KG-D6 block of RIL. Under direction of the Delhi High Court, the government had appointed a one-man committee under retired Justice A P Shah to go into the issue.

Shah, however, said the compensation should go to the government as it is the owner of all unproduced natural resources.

KEI-RSOS Secures Two Oil And Gas Blocks in KG Basin KEI-RSOS Petroleum & Energy, which currently operates five marginal gas fields in the KG Basin and markets the gas to industries, announced securing two oil and gas blocks in the KG Basin from the union petroleum and natural gas ministry.

The allotment of these blocks was part of the discovered small fields in global bids where the bid rounds were launched in May last year and blocks were allot ted under revenue sharing model last week. The two blocks allotted to the company together hold reserves of over 1,400 million barrels of oil and 35,000 million standard cubic feet of gas.

KEI-RSOS Petroleum is jointly owned by Lt Murthy Jasti of the River Bay group of Rajahmundry and KEI group owned

by Anil and Shobhana Kamineni of the Apollo Hospitals promoters' family.

The JV firm proposes Rs 200 crores to invest around over the next two years to exploit reserves from these blocks.

Maharashtra to Restart Wind Power Purchase Agreements After 3 Years

The Maharashtra State Electricity Distribution Company, the main power utility, is set to resume signing power purchase agreements with wind developers in the state after a gap of almost three years.

"The discom has assured us that pending PPAs of wind projects will be signed right away," said Sunil Jain, president of the Wind Independent Power Producers Association.

One developer confirmed that his company had been called to complete the formalities. "The discom will proceed in chronological order, with PPAs of those developers whose commissioned projects have been waiting the longest being signed first," he said.

For the past three years, unused wind generating capacity had been piling up in Maharashtra, with the MSEDCL reluctant to buy power at high prices from developers who had completed their projects.

Sustained pressure from the developers and some prodding by the Centre, which has embarked on an ambitious renewable energy programme, may have prompted the discom's change of heart.

About 450 MW of installed wind turbines, amounting to an investment of over Rs3,000 crore, remained unutilised due to MSEDCL's dillydallying and risked

Karnataka Set to Add More Green Power in 2017-18 Karnataka’s energy sector appears to be going green as the State is set to add more quantum of renewable energy to its grid during 2017-18 than conventional power. Of the total quantum of 3,975 MW of power to be added to the grid in 2017-18, renewable energy accounts for 2,375 MW. The proposed capacity addition of 2,375 MW of renewable energy includes 1,000 MW of solar power from the Solar Energy Park in Pavagada of Tumakuru district, according to the proposals for the energy sector in the State budget-2017 presented by Chief Minister Siddaramaiah.

Of course, the remaining quantum of 1,600 MW would come from two generating units with a capacity of 800 MW each at the newly set up Yeramarus Thermal Power Station near Raichur.

Lucky winners (from left to right): Diane Kibart, Bavley Farid, Cornelius Plath (product manager of TESTRANO 600), Ahmed El-Hamaky and FadiZatari.

Testrano 600:

Winner of The Smart Product of The Year Award Product Manager, Cornelius Plath, was delighted to accept the Middle East Electricity prod-uct award on behalf of OMICRON and particularly, the team who worked on the TESTRANO 600 development.

The award was made in the “Smart Power Product of the Year" category for OMICRON’s new power transformer test system.

Given that testing of power transformers is quite time consuming with different test sets, lots of re-connecting, and multiple trips up and down the transformer, TESTRANO 600 cuts testing time hugely as the three-phase source allows excitation of all three windings at the same time. This gives customers

the ability to measure the voltage ratio and actual phase shift. In today’s economic environment time is a valuable resource for many of our customers.

Therefore, OMICRON’s vision to develop a test system which makes power transformer testing quicker and easier than ever before, has been realized.

TESTRANO 600, provides a powerful three-phase source to enable the user to perform the most common tests, such as turns ratio, excitation current, DC winding resistance, dynamic resistance and shortcircuit impedance/leakage reactance, much quicker and with less re-connecting than before. The unit itself is really compact, weighing only 20kg/44lbs and can also

TESTRANO 600, OMICRON’s portable three-phase power transformer test system ||www.electricalmirror.net||

be used to demagnetize transformers. By combining TESTRANO 600 with the CP TD1 accessory power/ dissipation factor and capacitance measurements can also be performed.

This is the third product award for OMICRON in the last three years including “Best Product” at Elecrama, India for its circuit breaker test set, CIBANO 500, and “Best Innovation of the Year” at Middle East Electricity, UAE for its voltage transformer set, VOTANO 100.

This is a true reflection of the company’s emphasis on innovation and its investment in new product development.

The integrated three sources and the simple wiring concept speed up and simplify power transformer testing.

Switchgears, control panels and capacitors overview

Switchgears and control panels form a part of power distribution equipment and are widely used in power grid or electricity distribution systems. Low-voltage & medium-voltage switchgear are used in many industries such as oil and gas, and paper and pulp, while high-voltage switchgears are primarily used in power substations. Capacitors are widely used as parts of electrical circuits in many common electrical devices and also in power distribution systems.

Switchgears: Include devices such as circuit breakers, protective relays and fuses that enables the continuous electric current transfer and protection against current overload, short circuit, and insulation failure. Types by voltage range include High voltage (HV) (>36 Kv), Medium voltage (1kv to 36Kv), Low voltage (<1 Kv). Types of HV switchgears include Air-insulated, Gas-insulated, Oil-insulated, Vacuum-insulated Control panels/gears: Control panels/gears comprise a casing/console that holds the switches, metres, safety equipment, indicators and warning systems to control/monitor a specific device/process. They are mostly an integrated part of switchgears,equipped with push buttons & analogue instruments. Touchscreen control panels are also gaining popularity.

Capacitors: Capacitor is a key passive electrical component used to store energy in electrical and electronic equipment or devices. Capacitors help to improve the overall power factor (PF) of the system and form an important part of an energy efficient system. They are widely used in consumer electronics, telecom devices, IT hardware and power distribution systems.

T&D to drive the Indian LV switchgear market

Investment in the construction, utilities and renewable energy sectors is driving the Indian low voltage switchgear market. With the residential segment witnessing robust growth to meet the rising demand for real estate in the country, lucrative ||www.electricalmirror.net||

opportunities for LV switchgears will emerge from this sector too. New analysis from Frost & Sullivan finds that the market earned revenues of $929.7 million in 2014 and estimates this to reach $1,405.2 million in 2020. The study covers air circuit breakers, moulded case circuit breakers, motor protection circuit breakers, changeover switches, contactors and relays, miniature circuit breakers, residual circuit devices, distribution boards, and switching devices. GoI plans to expand and develop the T&D network and augment power capacity are expected to fuel the need for LV switchgears in the country. Schemes such as Rajiv Gandhi Grameen Vidyutikaran Yojana and Restructured Accelerated Power Development and Reform Programme that have been designed to encourage investments at the distribution level will be among the initiatives that will boost the demand ELECTRICAL MIR ROR || APRIL 2017 29

for LV switchgears. On the downside, energy-intensive industries such as oil and gas, which have traditionally driven the primary demand for LV switchgears, are holding back future investments due to the weak macroeconomic environment, tightening liquidity, and a lack of policy reforms. These industries have adopted a wait-and-watch strategy, creating a lull in productivity and the demand for LV switchgears.

With industry sentiments and overall economic conditions anticipated to improve by the middle of this year, the Indian LV switchgear market is likely to witness higher growth rates over the next five to six years, a point that needs to be noted. Fast-paced reforms planned by the government will play a pivotal role in getting the market back on track. LV switchgear manufacturers will still have to contend with increasing pricing pressures due to intense competition. The revenuegenerating potential of market participants will suffer to some extent due to curtailed investments and the long approval process for utility and infrastructure projects.

To sustain themselves, LV switchgear manufacturers must adopt new strategies and introduce innovative products.

They should also expand their distribution network and focus on modular devices, which are expected to witness strong adoption rates in the Indian market.

Indian Switchgear Industry

The Indian electrical equipment industry comprising of multinationals, large medium & small players is fully geared up producing, supplying and exporting a wide variety of electrical equipment including switchgear and controlgear items needed by the expanding industrial and power sector on which we focus in this article.

This industry sector in fact manufactures the entire voltage range from 240 V to 800 KV. 1200 kV equipment is under indigenous development for the 1200Kv Test station at Bina, MP. The current technology level in India is Contemporary. It is estimated that the present size of the Indian switchgear industry, is around Rs. 12,000 Crores . The industry grew by about 21% in volume terms in 2010-11. Overall exports decreased by 8%, whereas imports increased mainly for MV/HV by more than 25%. Weightage of Switchgear industry based on IEEMA electrical industry Index is 15.2%. The population of IEEMA members from switchgear industry is around 140 members.

Currently, the MV & HV segments are suffering from overcapacity due to lack of orders. Inadequate demand could be due to insufficient planning by the users and delay in finalizing tenders. Unfortunately bunching of orders also creates supply-delivery problems, Also L1 ( lowest quoted price) procurement system followed by all utilities i.e. procuring products at lowest price creates a hurdle for bringing good quality material in the system. Further insistence on repeated type testing of products in spite of inadequate type testing laboratories poses 30

additional delays and harm to the equipment.

Conclusion

Indiaâ&#x20AC;&#x2122;s electrical equipment industry has shown excellent sign of growth in the past few years. The major growth drivers are cables and switchgears market.

The LV switchgear market is further expected to grow at a CAGR of 6.1% during 2016-2020 and is expected to reach Rs. 7,609 Cr by 2020. Commenting on the performance of switchgear industry in India, Electrical Sector it can be said that the performance has been mixed. Segments such as residential & commercial infra and RE such as solar have seen significant switchgear demand but there has been lower than expected demand from power capacity expansion projects. Also industries such as oil & gas have been conservative in their investments due to macroeconomic and liquidity challenges. The switchgear industry in India mainly covers LV switchgear products such as Air Circuit Breakers (ACBs), Moulded Case Circuit Breakers (MCCBs), Miniature Circuit Breakers (MCBs), Residual Current Devices (RCDs), and fuse gear products.

MCBs, RCDs, and DBs are low technology and highly price sensitive product segments with several small & medium participants operating at regional levels. This is a high volume business with demand primarily from commercial and residential segments.

It is observed that the market for changeover switches (COS) and other switching devices (SDs) is a mature market with stable demand predominantly from small industrial end users. Besides being low-cost products, CoS and other SDs find preference with these end users because of their proven and rugged technologies and ease of maintenance and repairs. As per IEEMA, the current size of the LV switchgear industry is Rs. 11,200 Cr out of which the domestic switchgear market comprising of products such as MCBs, RCCBs, and DBs account to Rs. 2,500 Cr. It is estimated that the switchgear industry in India will reach Rs. 21,500 Cr by 2017 on the back of strong infra development, govt initiatives towards power capacity expansion and augmentation and development of the T&D network.

However, while the overall domestic market grew between 5-10% last year, the first two quarters of this year witnessed a slow growth. The main factors which are driving the growth of switchgear industry in India is resurgence of projects in infra and real-estate sectors, rising aspirations of consumers and growing demand for branded goods. The govt.â&#x20AC;&#x2122;s amplified focus on infra development and launch of ambitious smart cities project would further accelerate the demand of quality electrical equipment. Even, the consumers nowadays are willing to pay ||www.electricalmirror.net||

extra for better quality products which are driving the growth of the electrical industry. The switchgear market will continue its growth trajectory given the aggressive reforms initiated by the govt through programmes such as Power for All, Make in India, the Integrated Power Development Scheme, Housing for All and the Deendayal Upadhyaya Gram Jyoti Yojana. The overall impetus given to the T&D will in turn drive the demand for switchgear and electrical equipment industry as well.

On the growth drivers front it can be said that govt. initiatives and reforms for expansion and development of the transmission and distribution network and power capacity augmentation: Significant investments of the Government of India towards power distribution with the objective of increasing access to reliable power supply and to reducing AT&C Losses, including through schemes such as Deendayal Upadhyaya Gram Jyoti Yojana and Restructured Accelerated Power Development and Reform Program, besides modernisation of the existing network, will provide boost demand for LV switchgear products. In addition, plans to add an additional generation capacity under the 12th FYP will subsequently increase the requirement for evacuation devices for the additional power, driving demand for LV switchgears in India.Increased demand from the renewable energy segment: Government incentives, favourable foreign investment policy and vast untapped potential of renewable energy will drive renewable energy generation in India. The RE market has grown from about 12 GW in 2008 to 28.2 GW in 2013, growing at approximately 16% per year and this growth is expected to sustain at current or higher levels during the 2016-2020 period. As a result demand for LV switchgear, especially for MCCB and MCB products, is expected to increase significantly.Revival of the industrial segment: Improvement in the performance of industries, declining inflation, increasing demand, particularly from the residential segment, announcements in the 2015 Union Budget to address the structural issues plaguing industrial and infrastructure sectors, collectively, are expected to benefit the manufacturing sector. Additionally, the GoI focus on initiatives such as â&#x20AC;&#x2DC;Make in Indiaâ&#x20AC;&#x2122; is expected to further propel manufacturing and industrial segment growth. These factors are expected to translate into the increased demand for LV switchgears from the industrial segment. Growth in the residential segment: Policy reforms such as allowing 100% foreign investment in the real estate sector, tax benefits for foreign investors, and focus on establishment of smart cities are expected to contribute to the growth of the residential segment at 30% over the next decade.

Further, the increasing urban population with expectations to cross 590 million by 2030, and growing household income are some of the major factors that influence demand for residential real estate. Moreover, increasing construction in Tier II & III cities and increasing awareness among end users for protective devices in these cities are expected to have a positive impact on the LV switchgear market over the medium to long term. It is also believed that growing infra and construction segments; expansion and development of T&D network and power capacity augmentation; and expansion in key industry segments will contribute

to the growth of switchgear industry whereas the capital expenditure in real estate will spur the growth.

The challenges however remains. The unorganised sector particularly for domestic switchgear products such as MCBs and RCCBs still continues to grow. The other factor remains that while the industry has set benchmarks, continuous development needs to be done to foster new technologies. It is equally necessary to keep raising the bar of safety standards to ensure that only standardised switchgear products occupy the shelves in the market. The increasing competition from the unorganised sector along with the lack of standardisation and design parameters is adversely impacting the quality of products and growth of the industry. The increasing trend of customisation is hampering the growth of this market in India.

However, the industry is emerging from a period of prolonged slowdown and we are hopeful that quality products will prevail over their cheaper counterparts in the coming months. Given that a no. of fire incidents every year happen due to short circuit, people now prefer to make one time investment in high quality products. Some of the major challenges that are hampering the growth of switchgear industry include low budget allocation during project planning, increasing pricing pressures due to high competition, and uncertainty and delays in implementation of various power reforms.

The Indian market for LV switchgear is competitive, particularly for volumedriven products such as MCBs and MCCBs, making it difficult for multinational companies to sustain their market share with decreasing profit realisation.

The increasing pricing pressure coupled with fluctuating raw material prices and imports from other Asian countries is acting as a deterrent to market growth as per its actual potential. It can also be pointed out that the delays in the evaluation and approval procedures at the implementation stage create uncertainty and lack of confidence in private investors, resulting in creation of artificial demand periodically, with manufacturers confronting irregular and bunched demand. This results in overbooked factories, further delays and makes the production planning process excessively challenging. Another concern includes that LV switchgears, which account for more than 55% of the total market, has a higher share of unorganised players and it is anticipated to increase in the coming years. The forward integration of these unorganised players to medium and high voltage segments can lead to an increase in the unorganised market share in these segments. However the challenges for Indian switchgear industry could be summed up as high level of price competitiveness, liquidity challenges, and pace of infra and power expansion projects.

Innovation in switchgears is primarily in terms of the aesthetics and customised features offered by the products such as improving the product lifecycle, tamperproofing, increasing safety & handling, improving user-interface and focus on multi & niche functionality. MNCs and established manufacturers usually spend more on product improvement and the frequency of updating product features is usually 2-3 years.

• The GoI announced a massive RE production target of 175,000 MW by ELECTRICAL MIR ROR || APRIL 2017 35

Focus: renewable energy

2022; this comprises generation of 100,000 MW from solar power, 60,000 MW from wind energy, 10,000 MW from biomass, and 5,000 MW from small hydro power projects. â&#x20AC;˘ The facility in Kamuthi, Tamil Nadu, has a capacity of 648 MW and covers an area of 10 sq km. This makes it the largest solar power plant at a single location, taking the title from the Topaz Solar Farm in California, which has a capacity of 550 MW.

Budget 2017

Transform, Energise and Clean India' is the agenda set by the government for the country for 2017-18, Finance Minister Arun Jaitley said in his Budget 2017 speech. While the 'Clean' part of the TECIndia agenda stands for "Clean the country from the evils of corruption, black money and non-transparent political funding," the Budget also brought in relief for companies engaged in the creation of renewable energy in the country. Budget 2017 either reduced or completely did away with taxes and levies on machinery used for the general of solar cells, wind energy, fuel cells, biogas, and more. The Budgetary allocation to the Ministry of New and Renewable Energy was hiked by 8.7% to Rs 5,036 crore to Rs 5,473 crore. For solar cells and solar power: The basic customs duty on solar tempered glass for use in the manufacture of solar cells, panels and 36

APRIL 2017 || ELECTRICAL MIR ROR

modules has been removed completely. Earlier a BCD of 5% was levied. BCD is an additional custom duty is charged in lieu of the excise duty duty applicable on similar goods manufactured and produced in India.

The parts and raw materials for the use in the manufacture: The government has cut the Countervailing Duty (CVD) by half on the parts and the raw materials used to manufacture solar tempered glass. Countervailing Duty (CVD) is an additional import duty charged on imported goods. Solar tempered glass is used in solar photovoltaic cells and modules, solar power generating equipment or system, flat plate solar collector, solar photovoltaic module and panel for water pumping and others. In the Budget presentation, Jaitley said, "It is proposed to feed about 7,000 (train) stations with solar power in the medium term. A beginning has already been made in 300 stations. Works will be taken up for 2,000 railway stations as a part of 1000 MW solar mission."

Wind Energy: The BCD, CVD and Special Application Tax on resin and catalysts used in the manufacture of cast components for Wind Operated Energy Generators [WOEG] have been eased to give a push to wind power generation. On these, BCD has been cut from 7.5% to 5%, CVD has been reduced to zero from 12.5%, a huge cut, and the SAD has been brought down to nil from 4%.

Special Additional Duty (SAD) is levied on all imports. ||www.electricalmirror.net||

Fuel cell based power generation: The levies on the import of machinery used for fuel cell based power generation has also been reduced in the Budget. The Annexure said reduced the BCD on the machinery from 7.5% - 10% to 5% while the cut was cut by half to 6% from the earlier 12.5%. However, this is subject to certain specified conditions.

Biogas: The Budget cut the BCD on machinery used in balance of systems operating on biogas/ biomethane/ by-product hydrogen to 5% from the earlier 7.5% - 10% and CVD to 6% from the earlier 12.5% levy.

The Budget has given a boost to RE, announcing another 20,000 mw of solar park development in phase II and a slew of duty reductions on components for fuel cell-based power generating and biogas systems, as well as wind energy equipment. The Budget announced solar power supply at about 7,000 railway stations in the medium term but a beginning has already been made at 300 stations, said finance minister Arun Jaitley. "Work will be taken up for 2,000 railway stations as part of the 1000 MW solar mission." On the other hand, Power, coal, renewable energy and mines minister Piyush Goyal was pleased with the proposals. "Through honest and transparent bidding, we have been able to bring down cost of renewable energy. The power sector is fast moving towards profitability and self-sufficiency with the UDAY programme. Power and mining sectors have received all that we had requested," he said. ||www.electricalmirror.net||

Budget Analysis and Conclusion

The Indian power sector has an investment potential of Rs 15 trillion in the next 4â&#x20AC;&#x201C;5 years, thereby providing immense opportunities in power generation, distribution, transmission, and equipment, according to Union Minister Mr Piyush Goyal. The govt.â&#x20AC;&#x2122;s immediate goal is to generate two trillion units (kilowatt hours) of energy by 2019. This means doubling the current production capacity to provide 24x7 electricity for residential, industrial, commercial and agriculture use. The GoI is taking a number of steps and initiatives like 10-year tax exemption for solar energy projects, etc., in order to achieve India's ambitious renewable energy targets of adding 175 GW of RE, including addition of 100 GW of solar power, by the year 2022. The govt has also sought to restart the stalled hydro power projects and increase the wind energy production target to 60 GW by 2022 from the current 20 GW. India has an ambitious target of 175 GW of solar, wind and other RE by 2022. The financial needs are mammoth and India needs to look beyond fiscal allocations if the signals for clean energy have to be bold and consistent. Solar, ELECTRICAL MIR ROR || APRIL 2017 37

Focus: renewable energy alone, would require $100 bn in debt to reach 100 GW. International debt markets, estimated at $95 tn, are the world’s largest pool of capital and need to be made accessible to Indian developers at affordable cost. The budget must be evaluated against this scale of need and opportunity. The role of public funds should be to either catalyse action, attract investment, or underwrite risk.

Let us first examine fiscal priorities to catalyse action.

Compared to last year. This year the allocation to the MNRE stands at Rs 5,473 Cr. As much as 74% of the outlay is directed to grid-interactive renewables, specifically mentioning the second phase of solar park development for 20 GW of capacity.

The total budget is further split between Rs 3,361 crore for solar and only Rs 408 crore for wind, a clear indication that the government will continue to prioritise solar. Additionally, the budget extends support to power 2,000 railway stations through solar, under the Indian Railways 1GW solar mission. Smaller sums of Rs 135 Cr and Rs 76 Cr have been earmarked for small hydro and bio-power, respectively. Despite recent suggestions, large hydro remains outside the purview of RE. One continuing area of uncertainty is the role of the National Environment Fund (NEF). The cess on coal remained unchanged at Rs 400 per tonne. While the total cess collected (projected up to 31 March 2017) was a mammoth Rs 54,336 Cr, only Rs 25,810 Cr have been transferred to NEF. Of this, under half (Rs 12,427 Cr) has been spent on renewable energy projects. While nearly all of the budgetary allocation to renewables in 2017-18 will be from NEF, the budget could have clarified the proportion of the cess that would be transferred to NEF. Another uncertainty is how the goods and services tax (GST) will impact renewables.

Researchers at the Council on Energy, Environment and Water (CEEW) find that if solar components were categorised based on current levied tax rates (including exemptions and subsidies), GST would impact solar tariffs minimally. However, if preferential tax benefits to renewable energy were not accounted, then GST could raise utility scale solar tariffs by as much as 9.5%, hampering progress.

But how has the budget performed in attracting new investment? Two market opportunities stood to gain significantly from strategic budgetary support. First, residential rooftop projects could create 15 GW of RE capacity in India by 2022.

While budgetary support was extended for housing infra, no direct support was announced for rooftop solar. Secondly, replacing 15% of India’s irrigation pumps with solar pumps could build 20 GW of capacity. Aiming to double farmer incomes within four years, the budget discusses mainstreaming and interlinking Primary Agriculture Credit Societies with District Central Cooperative Banks. If this increases access to low-cost loans, the incentive to invest in the upfront capital expense for solar pumps could increase.

The budget’s real test lay in its approach to mitigating financial risk in the renewable energy, where capital costs are high, payback periods are long and off-taker, construction and foreign exchange risks raise cost of debt significantly.

CEEW research shows that 70% of the costs embedded in already low solar tariffs 38

APRIL 2017 || ELECTRICAL MIR ROR

owe to return on equity and debt servicing. But no budgetary support was extended to any agency to address risks. Moreover, financial support to the Solar Energy Corporation of India, the nodal agency for commissioning many solar and wind projects, has been halved to Rs 50 Cr. Nor has the budget given any impetus to technology development.

Only Rs 144 Cr has been

budgeted for research and development, nearly half of last year’s allocation. A recent CEEW study showed that energy storage has a number of current commercial applications for telecom towers, petrol pumps, commercial establishments, rural ATMs, and academic institutions. Yet, funding remains constrained. In 2016-17 Rs 20 Cr was allocated for developing, testing and deploying energy storage technologies. In 2017-18 there is no allocation for energy storage, which could exacerbate challenges with integrating RE into the grid. Again, despite some focus on transport infrastructure, no allowances have been made for electric vehicles or biofuels.

While total budgetary outlay to renewable energy marginally increased, there is little to celebrate. This budget is unlikely to catalyse action, attract private investment or underwrite risks. An opportunity was lost.

Excess power generation capacity provides India an opportunity to shift completely to green energy. If the country can halve storage technology prices in 10 years it can do without the need for new coal based plants, a study by The Energy and Resource Institute (TERI) said. The TERI report indicated that current installed capacity and the capacity under construction would be able to meet demand till about 2026, keeping India power sufficient. The report estimates that no new investments are likely to be made in coal-based power generation in the years prior to that. The TERI report also estimates that beyond 2023-24, new power generation capacity could be all RE, based on cost competitiveness of renewables as well as the ability of the grid to absorb large amounts of RE together with battery-based balancing power. It also said that all new investments in power generation are likely to develop new storage technologies.

TERI’s demand scenario suggests that current installed capacity and capacity under construction and after taking into account retirements, would be able to meet the demand till about 2026, or so. This suggests there would be no new coal-based capacity investment that would be approved till about for years prior to that. Between 2014 and 2024, India has a 10-year window. If in this 10 year window, the price of solar and battery reaches the Rs 5 per unit mark, all new capacity additions would be in renewables. In case, this price goal would be achieved, or nearly achieved, by 2023-24, if appropriate infra to absorb large amounts of Renewable Energy, together with battery based balancing power, is in place.

Interview

The biggest factor behind our success is our focused approach.

In business, what we should not do is as important as what we ought to. Collaborations are another important contributor to our success. I have always believed in growing with our partners and stakeholders. As the famous African proverb goes, “If you want to go fast go alone, if you want to go far, go together.” We will continue to adopt the collaboration model across all our businesses. ||Mr Hartek Singh || Hartek Power Pvt. Ltd|| Chairman & Managing Director, ||

Q

. What are the focusing business areas that you are catering in and what is the success story behind this?

For the past 25 years, we have been majorly active in the transmission and distribution space. We started out as an electrical trading company of high-voltage electrical components, like transformers, breakers, relays, etc. Gradually, we identified the problems of the industry and started focusing on addressing their energy needs. By mid 1990s, we were providing one-stop power solutions to the industry.

Collaborations have been one of our core strengths, and leveraging these tie-ups, we shifted gears in 2007, graduating from an electrical trading company to an engineering company providing world-class designs, project managements and construction expertise in the power system value chain. In a span of just three years, we were commissioning a substation of up to 220 KV voltage class every month. Our world-class project management and design expertise stood us in good stead when we ventured into the solar EPC domain in 2013. In fact, we were part of India’s first ever utility-scale solar plant in Amritsar. We have connected close to 600 MW of solar power to the grid already. We also ventured into assembly of medium-voltage switchboard panels and control relays in 2012, and this backward integration model has paid us rich dividends.

The biggest factor behind our success is our focused approach. In business, what we should not do is as important as what we ought to. Collaborations are another important contributor to our success. I have 42

always believed in growing with our partners and stakeholders. As the famous African proverb goes, “If you want to go fast go alone, if you want to go far, go together.” We will continue to adopt the collaboration model across all our businesses.

Q. The company is one from the

most leading brand in the power and infrastructure so what are new products and services you are providing at it best according to the changing Indian market value and customer demand?

We feel that the services you provide are the most crucial differentiator, be it executing a project or manufacturing a product. That’s the reason why we are investing so much in services. We have also introduced a mobile testing van called “Grid Doctor”, which instantly caters to grid and power failures in industry and utilities.

Another major focus area for us is distributed solar.

Renewable energy in general and distributed solar in particular is the answer to climate change and constantly increasing electricity prices. We have a separate Rooftop Solar business division which has executed about 13.5-MW projects so far. We cater to the industrial and commercial categories in rooftop, but have plans in place to enter the residential category, too, with our solar solutions.

Q

. What are the opportunities and challenges that you are facing now and what you doing to cope with these hurdles?

The country is on a fast-growth trajectory, but to keep the momentum going, availability of uninterrupted power supply is a must. India needs electricity to fuel the growth of every sector, be it large-scale or small scale, manufacturing, healthcare or education. The growing recognition of the role of accelerated electricity augmentation in rapid economic growth has opened the doors for many private players in both power generation as well as transmission and distribution.

The growth patterns in the industry suggest that there is a huge scope for private enterprise. The renewable energy segment, in particular, has attracted huge investments from many big private players.

But challenges still remain. For instance, delays in approvals and other procedural delays affect the timeliness of the projects. The most crucial aspect of any power project is its timely completion without compromising on quality. We, at Hartek Group, have commissioned more than 150 substation projects, and quality and timely execution have been the hallmark of all these projects.

Upgrading grid infrastructure will pose a huge challenge in times to come. Operation and maintenance is another area where the power industry has a lot of catching up to do. However, the Hartek Group has been taking care of this aspect right from Day One by carrying out the complete Annual Maintenance Contract (AMC) of every project completed by the company.

Getting trained manpower is yet another big challenge.

We have in-house training facilities in place to fill this gap.

Q. What you think that how we should grow ||www.electricalmirror.net||

to meet the desire target set by government support. To boost the morale of private players, state and should government going hand in hand utilities should make timely and assured payments to them. with the private sector to overcome the challenges in the power and infrastructure? . Please shed some lights on target set by The Central government has identified the power government to get "Power for all" by 2019, sector as a key sector in ensuring sustained industrial growth. It has taken some welcome steps to upgrade is government doing much efforts to achieve power infrastructure and boost generation. However, this target or should it take some or more there is a need to further improve the generation action to achieve this target?

Q

and transmission and distribution capacity by adopting innovative strategies.

Renovation and modernisation of generation equipment is required to improve the performance of old power plants. There is a need to make coal-based power plants more efficient. The National Grid network should be suitably upgraded so that there is no pressure on the existing transmission lines. Renewable energy requires special focus. The government should formulate consistent long-term policies which boost investments in renewable energy.

The government should make it a point to collaborate more effectively with the private sector so as to build the T&D infrastructure on a war footing, much on the lines of the proactive approach it has adopted to boost solar power generation.

Huge private investments are required for installing power plants. In order to increase participation of the private sector, the government should come up with sustainable energy policies, backed by financial

The Centre has set itself a target of achieving “Electricity for All” by 2019. In the past, it has been witnessed that the demand for power has not been adequately met on account of several factors like lack of fuel supply and transmission and distribution constraints. In order to achieve the objective of 24x7 affordable power, the government should take a slew of measures to augment power generation and strengthen the transmission and distribution infrastructure.

Finance Minister Arun Jaitley has announced some appreciable steps in this year’s Budget to promote clean energy and ensure energy security. The allocation of a sum of Rs 8,100 crore to double the solar park capacity to 40 GW by 2020, a higher spending on rural electrification and the decision to fully electrify 18,452 villages by March 1, 2018 at a cost of Rs 4,814 crore will go a long way in promoting clean energy and inching closer to the objective of “Electricity for All” by 2019.

The main problem is that the cost of supplying power

to remote areas is the highest, but the capacity of consumers to pay for power is the lowest in these areas. The challenge is the same for both grid extension and distributed generation. The transmission system has evolved from a system of sub-regional networks to strong regional networks interconnected by high-voltage transmission lines. Though all the regions are interconnected, there are persistent congestion problems and corridor bottlenecks which constrain the flow of power from surplus regions to deficit regions. The avowed objective of affordable power for all cannot be achieved unless we have a robust distribution network in place.

The central government alone cannot fund the entire effort and state governments as well as the private sector will be required to pitch in with funds. The focus should be on rural electrification and energy security.

Q. What are your international plans so far

and do you expanding the business further?

Our country is growing at a rapid pace, and with 300 million people still without electricity, the Indian power sector presents endless business opportunities. While we will strive to improve our domestic market share across all our businesses, we aim at building a truly global company which follows world-class processes and has people adding value to it at every step. We are looking to tap the Middle East and North African (MENA) region through strategic tie-ups with leading companies there.

India Headed For Top Slot In Global Led Lighting Market

T

he Light Emitting Diode (LED) market in India has been growing over 50% for the last five years (2009-10 to 2013-14) and expected to sustain this growth rate in the next five year (2014-15 to 2018-19). Although late, the government of India has announced a lot of incentives and measures in order to prioritize LED manufacturing in the country. However, there are lot of LED Lamp assembling companies in India, who design and make LED lamps but they import basic LED chip elements. The quest for energy efficiency is transforming Indiaâ&#x20AC;&#x2122;s Rs 15k Cr a year market for lighting systems. Conventional lamps are being replaced by efficient ones starting from simple LED bulbs to sophisticated movement-detecting lighting systems for smart cities and businesses, opening up a host of opportunities to lighting companies from the very bottom of the pyramid to high-end consumers.

Let us see about the industryâ&#x20AC;&#x2122;s changing dynamics in the following lines.

India is poised to emerge as the largest market for lighting systems based on LEDs (light-emitting diodes), thanks to the Narendra Modi-led government's UJALA (Unnat Jyoti by Affordable LEDs for All) scheme for replacing all inefficient bulbs with these energyefficient lamps.

"With India selling 770 million LED bulbs every day, the country will soon become the LED capital of the world. Prices of LED bulbs have come down to 55 pence (Rs 52) from over 3.5 pounds (Rs 332) two years

44

APRIL 2017 || ELECTRICAL MIR ROR

ago," a govt statement quoted power minister Piyush Goyal as telling investors in London in 2016. Today, 12% of all LED lighting systems sold in the world is consumed in India, according to Saurabh Kumar, managing director of Energy Efficiency Services. The company, promoted by state-run power utilities, is the nodal agency for implementing the UJALA scheme.

Kumar said the rise in India's share of consumption of LED lighting systems was primarily being driven

by LED bulbs promoted through the UJALA scheme but also includes all forms of lighting. More than 9.7 crore LED bulbs have been distributed so far under the scheme. UJALA's beauty is that there is no subsidy involved, neither by the Centre nor by any state government. China had a (bulb) replacement programme but that was based on subsidy," Kumar said.UJALA has brought down the price of an LED bulb to Rs 85 for a 9-watt on an average. Some states have received even lower prices during bidding "UJALA is providing technically best lamps of nine watt capacity. Let's say you can get an LED bulb for an average $1.25 in India against $3.5-4 two years back," Kumar said referring to Goyal's pounddenominated pricing for his London audience. The UJALA scheme is part of the Modi government's larger plan for demand-side management, which has been dovetailed into the broader climate strategy for meeting voluntary target for cutting greenhouse gas emissions as part of the global climate deal.

Lighting sector accounts for about 20% of the total power consumption in India. Most of the lighting needs in domestic and public sectors are met by inefficient incandescent or CFL bulbs. The UJALA scheme aims at replacing all the 77 Cr inefficient bulbs in the country with LEDs. It is estimated that once completed, the UJALA scheme would save Rs 40,000 Cr in annual electricity bills for consumers.

The scheme is also expected to result in reduction of 20,000 MW load, energy savings of 100 billion units and bring down emission of greenhouse gases by 80 MT/year.

||www.electricalmirror.net||

Energy efficiency is driving the lighting market

LED Lights unlike incandescent lights or fluorescent lights are electronically controlled and triggered for operations including switching “ON”, “OFF” or dimming etc. as required. LED lights which were initially used to replace incandescent bulbs are fast replacing all kinds of sources of light including fluorescent tubes, flood lights, signal lights, railway carriage lights and head lights or lights as otherwise used in road transport vehicles. In fact the low consumption of power by these LED lights make them a natural preferred choice particularly when power needs to be drawn from the batteries whenever power supply gets disrupted. In fact, the energy efficiency of LED Lights particularly at peak hours of load in the evening helps in substantially reducing these loads and thus curtail over load trippings of power in the evening. In fact this has also helped reduced cost and dis-comfort which was involved in using batteries as part of the emergency lighting service. Lighting as a whole contributes to 18-20% of total power consumption in the country. To bridge our energy deficit, we need to either increase power generation or reduce the need for power itself, through energy efficiency. If the entire lighting system of the country is converted into efficient LED lighting or smart connected lighting, our total lighting-related power demand will get reduced by half. It frees up about 30 GW of our over 300 GW generation capacity. That more than bridges our peak power deficit, which is the result of increased power consumption for lighting at peak hours. Secondly, in spite of the drive to electrify all the villages, there will always be parts of India where providing grid-connected power is not economical, as the cost of laying wire will be much more than the cost of power generation. About 20 Cr people, or 4-5 Cr households in the country, have either no access to power or get only intermittent supply. Making energy-efficient lighting, especially those run on solar power, available to them will solve our energy access problem.

Growth opportunities that energy efficiency offers to CoS in urban areas! Home lighting, lights used by businesses and organizations and infrastructure and street lighting are the three major areas of power consumption. India has about 3 Cr street lamps which remain lit for about 10 hrs/day, which is a major segment of consumption. For businesses, upgrading to energy-efficient lighting offers a high return on their investment by way of savings in power bill.

Payback period for upgrading all lighting systems ranges between 2-3 years. Almost 3/4th of all new lights bought by businesses are energy-efficient LED lights. There is also a trend among businesses to go for smart lighting, which can sense movement of people and the number of people in the surrounding and ||www.electricalmirror.net||

produce light accordingly. This intelligent lighting offers about 30% of energy saving in addition to the 50% saving that LEDs per se offer. Some CoS are now getting into what is called managed services. That is, CoS like to upgrade their lighting infra and they pay in installments for using that infra. Their savings from power bills helps them pay their instalments to the service provider. Manufacturing CoS as well as IT firms, which are very familiar with the concept of managed services, are going for this.

LED Street Lighting! Many states have started to adopt efficient street lamps because of the Smart City initiative, but a lot more is to be done. India has 5k towns and at least 100 large cities and 3 Cr street lights. Some cities have upgraded to connected smart street lights. One example is Naya Raipur, the new capital of Chhattisgarh. This city has probably the world’s most modern connected lighting infrastructure that is monitored remotely. The city engineer monitors the infra from his office. If a bulb needs replacement, it gets reported automatically. Upgrading the lighting infra of many cities in essential today. Finances of the state and the municipalities concerned are important in going for an upgrade. The upgrade is quicker where the municipality concerned has a clear financial model such as central govt funding or multilateral aid or lending. Besides energy saving, the cost of maintenance for efficient lights is less and the quality of light is also better.

Government initiatives on LED bulbs! In the consumer segment, about 30% of the lights sold today are LED bulbs and the rest are conventional bulbs. The large market share that conventional bulbs still enjoy is not because of any price advantage, but because they are more easily available in the neighbourhood. It’s a question of distribution. Some of the LED options are cheaper than conventional bulbs. We need to address this. Firstly, the products that should be adopted have to be of high quality and should be designed for the domestic market with high voltage fluctuation tolerance. Use of poor-quality products

can sabotage the adoption of LED bulbs as it would adversely affect public perception of the benefits of energy-efficient products. The next wave of LED adoption will get supported by a robust retailing ecosystem. We go to a nearby retailer to replace a bulb, not to a power distribution utility that stocks these products. The total lighting market in India as per industry estimates is Rs 15k Cr a year. This excludes new pockets of demand such as the remote areas where solar-powered LED bulbs would be required.

Challenges in LED Lighting industry: LED Lighting in India has indeed expanded and grown by over 50% annually over the last few years. India has the unique strength of excellent world-class R&D technologists in electronics which is the base for LED lighting industry. This is helping the Indian Lighting Industry to continuously incorporate new innovative improvements in performance of the LED Lights manufactured in India. However, the most critical hurdle in the growth of LED manufacturing in India is on account of inadequate development in manufacturing of LED chips and micro chips, as they still have to be imported at high cost resulting in constraints in developing larger variety, colors and performance and innovations in LED Lights.

Emerging New Technologies: In overseas markets, especially in Europe, exists projects where lights remain dim when there is no one in the street and the light intensity goes up when movement of people or vehicle is detected. Indian cities have not gone for this level of sophistication, but the journey has started.

The dual sensors which can now be incorporated in the Street Lights automatically sense the presence of any moving person or vehicle on the road served by the Streetlights so as to brighten up the light and again when the moving person or vehicle moves ahead, the lights left behind are get dimmed and those ahead brighten up to make movement of traffic comfortable, convenient and safe.

Idea of achieving Nation’s objective: Owing to several measures taken by the govt the lighting industry is ELECTRICAL MIR ROR || APRIL 2017 45

witnessing a structural shift. Major initiatives of the govt for instance replacing conventional street lights

by LED Street Lights provide a significant opportunity for the players in the segments. GoI is laying a lot of thrust on the LED lighting, with an aim to conserve energy. With the idea of achieving Nation’s objective of not only becoming self sufficient in LED Lighting to meet the entire country’s requirement but also enhance its production, productivity and performance levels, India can be recognized as one of the best sources for LED Lights all over the world.

This objective and consequent action plan is real and achievable because India has the unique strength of young educated, innovative, committed Engineers who can continue enhancing performance of the LED products, find innovative ways to cut costs and mass produce them to be more competitive and thus meet the global requirements.

With the above objective successfully implemented, Indian LED Industry can make available to India 24X7 electricity supply. Energy conservation is more crucial than equivalent quantum of energy generation.

LED bulbs can play a great role here by conserving peak power demand in our country by 10,000 MW daily. If incandescent lamps are replaced by energyefficient LED Bulbs, it can save almost 100 billion units of power annually, thereby saving up to $7 billion (approx. Rs.43,750 crore) per year at its established level of annual consumption of power.

Of course with ever increasing demand for power for Lighting purposes across India, the potential for energy saving and financial benefit will indeed be much more. Considering the above, the whole LED 46

APRIL 2017 || ELECTRICAL MIR ROR

Lighting industry is gearing up to take the Lighting industry a giant step forward.

Curbing penetration of Chinese lights in India: The govt needs to incentivize domestic LED manufacturers to boost R&D activities on LED Lights in India by reversing the import tax structure, so that the import duty on complete LED Bulbs may be kept normal or high as in the case of other products, but on every raw material and component which goes into manufacturing of LED Lights in India should be reduced to zero. India has well recognized strength of technically educated and skilled people who can further improve design of LED Lights to deliver improved performance, enhance life of the LED Bulbs and to reduce cost of LED Lights through research on more efficient and lower cost raw materials and components which go into making of these LED Lights. This is imperative for the Indian companies to overcome stiff challenge from cheap low cost Chinese LED makers. More importantly, the authorities need to take measures against the cheap sub-standard LED lighting products imported through the grey markets and sold across India. It is impossible for domestic manufacturers to compete against the low prices of smuggled products coming through the grey market in India. Although these LED Lights are mostly of sub-standard quality, and the only Indian customers who look for cheaper market price, become a natural prey of importers of such LED Lights.

LED and Make in India: While promoting its ‘Make in India’ campaign, the Indian Government is doing a great job of national importance as explained above.

However, they must also publicise the fact that for

genuine benefit to the Indian consumers and the Nation, the Made in India products should be their only choice, as they fully comply with safety norms and satisfactory performance requirements as laid down in the Indian Standard Specifications. Above all, the products made in India will give good reason to the Indian buyers and the users to smile with pride of the fact that good quality LED Lights which they use are “Made in India”.

Few Reasons why LED Bulbs are the Future

LED lights have emerged as a powerful source for lighting over the past several years. Due to their numerous advantages over conventional lighting technology, they have swiftly gained prominence in the Indian lighting market. Although Indian LED lighting market is at a nascent stage, it offers innumerable opportunities for growth over the next few decades. As India represents one of the biggest lighting markets, it offers a lucrative option for LED manufacturers to set up their facilities in the region. Skilled labor, ease of doing business and demographic advantages provides a sustainable environment for the LED industry. Currently, the demand for LED lighting systems is primarily concentrated in the North & South regions due to growing urbanization rates and increasing number of govt initiatives that encourage the use of LED lights. The govt’s support through various regulations that promote the investments in energy efficient lighting technologies have expanded the applications of LED lights across various industrial, commercial & residential sectors. A rapidly growing automotive ||www.electricalmirror.net||

industry also provides productive opportunities for the use of LEDs in headlamps, rear lamps, turn signal and brake lights. Other important factors such as increasing infra investments, rapid growth of street lighting systems, decline in average prices of LEDs and various government and upcoming smart building projects are expected to drive the demand of LED lights in India. After years of research, trials, and errors, LED bulbs are finally starting to come good on their promise: an energy efficient light source that lasts a long time. While people are still to adopt this new lighting technology, it is only a matter of time before LED bulbs are everywhere.

Energy efficiency: We are more environmentally conscious than ever before. In fact, being environmentfriendly is in fashion today. We want to do every bit we can in order to save this planet. LEDs are more energy efficient that any other man-made lighting source. In fact, they are almost 75% more efficient than traditional incandescent bulbs. As people become more aware of LEDsâ&#x20AC;&#x2122; energy efficient benefits, and as the technology continues to evolve, we will see a faster adoption rate to this future of lighting.

Better lifetime: LEDs on an average have a lifetime of 25,000 hours. To put that in perspective, an LED bulb can comfortably last for over a decade. With technological waste being a major cause of concern in our fight to make this planet healthier, we are bound to move towards technology that lasts a long time.

||www.electricalmirror.net||

More possibilities: Unlike CFLs and halogens, LEDs are chip-driven. Thus, they can easily be configured to be in sync with your everyday living. For instance, they can be programmed to automatically switch off as you leave your home, and automatically switch on when you are just a couple of miles away. In fact, they can even be programmed to be in sync with your microwave oven to create the illusion that you are home, even while you are enjoying a beach vacation thousands of miles away. Possibilities are endless with LED bulbs. As we continue to use technology to make our lives simpler, LED bulbs are definitely going to be ubiquitous.

Affordability: LED bulbs are more expensive than CFLs and halogens. However, if you compare the costs with what they were about a decade back, LEDs have witnessed a sharp decline in prices. As companies continue to mass-produce these bulbs, and as the demand for these energy-efficient bulbs rises, they will become even more affordable.

Safer: Compact fluorescent bulbs contain mercury, which can be hazardous to your health. Since LEDs are solid-state lighting, they do not have any harmful gases or liquids. They are safe for you, and for the environment too.

Environmental Benefits: As fertile land becomes scarcer, we are undertaking continuing experiments on how to grow our food inside. We have been successful with growing leafy greens such as lettuce,

while experimentations are on with other kinds of food. It has been seen that LEDs are more conducive to growing food inside, since they run at cooler temperatures that are just perfect for plant growth.

As our farms move inside, we are bound to see a fast rate of adoption to LED lighting.

How using LED lights can help you save money

Although indoor lighting is an essential, most of us do not pay much attention to the costs associated with them, perhaps because itâ&#x20AC;&#x2122;s not a big-ticket expense.

However, it is not just the upfront cost of buying a tube light/bulb that you must take into account.

Other costs like replacement & power consumption also need to be considered carefully before making a decision. Since electricity consumption forms the bulk of the running cost of light fixtures, an energy efficient option like LED lights can help you save a good deal of money in the long run.

LED lights are much more eco-friendly, and are

ELECTRICAL MIR ROR || APRIL 2017 47

special theme: LEd & Lighting

up to 80% more efficient than fluorescent and incandescent lights.

Although the upfront cost of LED lights is slightly higher, their energy efficiency and durability compensate for it. “The return on investment for installing LEDs is so much quicker because of their longevity and light emission per wattage,” says Radeesh Shetty, Founder, The Purple Turtles, a decorative lighting company. LEDs may cost you 30-40% more than traditional lighting options, depending on the brand you choose, but they last four to five times longer. This not only saves you the effort of replacing them often, but also making them environmentally sustainable. Traditional lights and CFLs need to be replaced more frequently than LED lights, which are designed to function for years. Since LEDs have close to zero maintenance cost, every section of society stands to benefit from their use, given the extra savings that can be made from the lower power bills, which is the norm for LEDs.

India’s UJALA Story

UJALA is an extraordinary story of the realisation of the Make in India leading to a technological leapfrog from incandescent bulbs to LEDs within only half a decade. It is enabling the LED manufacturers to build a business that will potentially be able to compete at international level and meet the growing demand for affordable LEDs worldwide. EESL and UJALA have paved the way for large scale energy efficiency implementation in India. It has shown government stakeholders that energy efficiency can deliver multiple benefits within a short time period to all sectors, and importantly, with limited or no costs to the government. The potential for replication with other high efficient appliances and equipment is considerable and can continue to trigger investment, innovation and best-in class manufacturing, all of which are at the heart of the Make in India campaign led by PM Narendra Modi.

• UJALA has successfully distributed more than 100 million LED lamps across 120 cities in India resulting in a wide range of multiple benefits.

• The Indian LED market value grew by 10 times in just five years and annual domestic production increased from approximately 3 million LED bulbs in 2013 to 62 million in 2015 (Elcoma). It is now the second largest LED market in the world worth 21.4 billion INR in revenues in 2015 (equivalent to the GDP of the metropolitan area of Miami, US). UJALA has played an important role in this rapid growth.

• UJALA is reducing annual household electricity bills by about 15% saving consumers over 16 billion INR every year; equivalent to the GDP of Mumbai. Households can now use the money saved to improve their quality of life which, in turn, promotes wider economic growth and prosperity.

• EESL’s requirements are stimulating the development of a high quality Indian LED lamp manufacturing industry.India is now the 2nd largest LED market in the world,worth 21.4 billion INR in revenues per year and likely to continue to grow further (Frost & Sullivan).

• EESL’s LED bulk procurement has also contributed to the reduction in LED retail market prices from approximately 800 INR per LED bulb in 2012 to 200 INR per LED bulb in 2016 – leading to one of the fastest LED price reductions in the world. This has helped improve acceptance and availability of LEDs in the Indian market.

• EESL’s specifications, including the three year warranty 48

APRIL 2017 || ELECTRICAL MIR ROR

requirement, have ensured that the LED bulbs procured meet high quality standards with current failures at only 0.3%. This is helping build market confidence in the product.

• Saving scarce energy resources and cutting India’s carbon emissions by around 3 MT of CO2 per year. This is equivalent to the annual emissions of one 500 MW coal fired power plant or removing 2.7 million cars from the road per year.

• In 2014, LEDs had only a share of 0.1% of the annual residential lighting market in India. In 2015, LED share of the market jumped to a remarkable 15% and is forecast to reach 25% in 2016 (Elcoma).

• With EESL and UJALA, energy efficiency has delivered tangible benefits for state govt.’s allowing them to do more with more energy. It is a win-win solution by reducing household electricity bills and providing new job opportunities – ultimately delivering energy efficient prosperity. The state utilities are able to slow down the relative growth of electricity demand, enabling the existing capacity to meet a greater number of households & businesses and, potentially, reducing the chance of blackouts. Realising the benefits of UJALA, state govt.’s are now interested in establishing their own energy efficiency replacement programmes to deliver these benefits to an even greater number of people in their state.

Case study of the month

VARIOUS CASE STUDIES ON OPERATION AND CONTROL SCHEMES FOR GRID SUB-STATION Contdâ&#x20AC;Ś.

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. ele.pkpattanaik@optcl.co.in

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 Actuation of Earth Fault Relay for 40 MVA Auto Transformer: One 40 MVA 132/33 KV Power transformer tripped on Earth Fault though the main protection was available after shutdown.

Actual Observation:

a. This transformer was in loading condition and catering load successfully with the available another 2 Nos of transformers in the network being connected in parallel. b. After taking shutdown for maintenance check up, this transformer was idle charged and stood OK. c. When 33KV system was connected with loads, the Earth fault relay of 132 side B tripped after rise of load to 4.5 MWatt. d. Now by raising the limit of

50

Earth fault setting to 50 %, the transformer was charged once again. e. This time when around of 4.5 Mwatt was attended the neutral current becomes around 25Ampers. f. So it was confirmed either the problem is with primary side of the CT or Y phase isolator male contact in loosen condition. g. But it was the condition of Isolator contact in loose condition due to the development of spark at the isolator contacts at switchyard.

APRIL 2017 || ELECTRICAL MIR ROR

Action Taken:

1. Now the transformer was again taken shutdown.

2. The isolator contact was tightened and put into circuit again.

3. After attempt of the isolator work, the transformer was charged successfully.

Analysis:

a. The earth fault relay as used for this transformer was of Non-directional type with setting of 10%. b. Now due to looseness of the 132 KV Y phase isolator male contact and no flow of current on this

phase, the unbalance current starts to flow on the secondary side of the CT. c. So the Earth fault feature of the relay actuated and resulted with tripping of the transformer.

2.2 Automatic ON-OFF of the motorized isolator: At One of the 132/33KV GSS( Grid Sub-Station), during commissioning time while checking the electrical operation of one of isolator at local end, it was observed with automatic ON â&#x20AC;&#x201C; OFF of the isolator continuously.

Observations:-

1. The AC supply to isolator was checked and found with absent of R phase supply i.e the isolator was fed with 2 Phase supply (Y&B Phase).

2. The attempt of closing pulse was done, when the isolator was in OPEN condition.

3. The motor was running slowly and just after closing of the isolator, it was again rotating on reverse direction and causing opening of the isolator.

Analysis:-

a. Isolator motors rotate on supply from 3 Phase due to

development of RMF ( Rotating Magnetic Field) and on the basis ||www.electricalmirror.net||

of availability of voltage supply, RYB sequence or RBY sequence, the rotation results. b. In one case say ( RYB), if it rotates clockwise, then on ( RBY), it rotates anti-clockwise. c. So in one direction it closes the isolator and in other direction, it opens the isolator. d. In this situation because of missing of one phase ( R Phase), the balance 2 Phases try to meet the torque by drawing excess current from the available phases. e. Sometimes this current drawal on the basis of RMF development from the available 2 phases, causes the rotation of the isolators. f. In case this RMF if overcomes the

g.

h. i.

j.

inertia from rest, then that starts rotating.

But at the end point when the male contacts strikes the female contact, it bounces in opposite direction and pulsating RMF changes to rotate along the bouncing direction.

So it starts rotating in opposite direction.

But this nature of rotation only becomes possible if initial RMF overcomes the rest inertia.

In practice OLR (Overload relay) is provided, that helps to cut-off the supply due to flow of higher current than its limit. .

2.3 Tripping of DP relay at the receiving end:- Two numbers of feeders were connected radially on the same line. Once an insulator string was broken and due to lowering of Y phase conductor, the conductor touched the structure and resulted with Y-E fault. But the fault tripping was registered as Zone-3 at the sending end and Zone-1 at the mid-point receiving end with fault on same Y-E fault.

Observations:-

1. This line was connected with two feeders one being “T” connected in between the starting point and other at the end as like shown in the figure 2.3-A

2. Now the fault has occurred between the connected link of both the feeders.

3. Both the stations had 132/33 KV transformer banks and connected in parallel.

Analysis:-

a. The setting of the relay at sending end was considered by taking the distance up to station A. b. The fault has occurred in between the section of the link from Station A and Station B

||www.electricalmirror.net||

c. Now due to the use of Y-y Transformer, the DP (Distance Protection Relay) at station A got actuated and the load at this station got separated. d. But due to “T” connected line, the fault on the line did not

get clear and fed from the generating station. So as per the setting, the actuation of

fault came as Zone-3 at the source end.

Action taken:

1. The line at station A was changed to LILO (Loop IN Loop OUT) as like shown in figure 2.3 B. 2. The DP relay at Gen station was set with the distance calculation upto Station A as the protected line.

3. Other relay settings were properly graded for the total system.

2. 4 Difficulties on the Relay gradation for 11 Kv system: one of the 33/11 KV structure, has Two 8 MVA transformers in parallel catering the radial load to 6 Nos of 11 KV feeders. Out of these 6 nos of 11 KV feeders, two numbers have been used with RGGBY ( Rajiv Gandhi Gramin Bidyut Yojna) scheme and fed with 11/0.4 KV pole mounted two phase transformers. It was found with un-equal current on each of the 11 KV feeders. So due to the unequal loading, the gradation on the relay was resulting problem.

Solution: These feeders were reviewed on the basis of its loading pattern and connections were changed to develop approximate equal load on each phase.

2. 5. Tripping of healthy transformers, resulting with BLACKOUT condition: At one of the 132/33 KV Grid sub-station, three transformers were running in parallel and catering the load to the 33 KV system. One day one of the transformer was taken shutdown for maintenance and after maintenance work, when this transformer was charged and put in parallel to the existing system, the other two transformers were tripped and resulted the tripping of this transformer and total blackout of the station.

Observation:

1. On detail checking it was found with the OPEN of R Phase limb of 33 KV breaker of the transformer just charged after shutdown and put into parallel condition.

2. This situation of R Phase open was due to removal of tie pin from the common tie rod.

3. This tie pin from store was brought and put into service and then parallel loading was done and successfully all three transformers were charged with the available load in the system.

Analysis: ELECTRICAL MIR ROR || APRIL 2017 51

Case study of the month ( setting being 10%= 80 Amp and unbalance current = 145.51Amp) 12. After outage of the healthy transformer, the 3Rd transformer tripped on Over Load condition, resulting BLACK OUT of the system.

1. The data of all the transformers were checked and found with % impedance as (No1&2 TRF = 9% and TRF No 3= 12%) and rating of being 40MVA. 2. During loading situation total load on the system was of 70Mwatt.

3. During Shutdown of No3 transformer, the sharing was of 35 MWatt on each transformer.

4. When this transformer (No.3) was put into parallel, after shutdown, the load sharing was changed as follows.

5. Considering the ideal situation, the load sharing could be as calculated below 6. PA= P(QA. ZB ZC)/ ∑, PB= P(QB. ZC ZA)/ ∑, PC= P(QC. ZA ZB)/ ∑,∑= (QA. ZB ZC+ QB. ZC ZA + QC. ZA ZB)

2. 6. Connection of Two incoming feeders for the 33/11 KV Sub-Stations and power flow behavior during radial connection and inter-connected situation: This sub-station has the facility of connection from two different 132/33 KV Grid sub-station. Generally this 33/11 Kv sub-station draws power either of the grid with other in OFF condition. But in case of interconnection for both supplies at this end, it was observed with in-coming of power from one Grid and out-going to the other grid.

Analysis:

1. The connection from any one of the 132/33 KV grid has the only way to avail the power supply, so as per the requirement of the load at this station, power used to be drawn from the grid.

2. But for the case of inter-connection from both the grid, the power flow drawal now depends upon the following factors

So PA = PB= 70( 40x9x12)/( 40x9x9 +40x12x9+ 40x9x12)= 27.1MW So PC= 15.8MW. Now healthy current on each phase for TRF1&2 on 33 KV side= 499.09Amp ( Assume P.F= 0.95) and TRF3= 290.98A on 33 KV side.

7. But due to OPEN of R phase limb, the current on this phase for TRF3= 0Amp, but due to parallel connection of all the transformers, the requirement of R Phase Load current could be shared by the available healthy transformers.

8. So current on R phase for the healthy transformer could be raised.

9. So due to this abnormal current flow, the residual current passed on the E/F element.

10. The transformer No3 was provided with E/F element of Directional nature and in this situation, as there was no any residual voltage development, this relay did not actuate.

11. But Transformer No1&2 was being provided with E/F element and due to setting being Non-directional in nature the tripping of E/F element resulted 52

a. voltage profile of the grid sub-station b. Distance of grids from this station. c. Load availability at the Grid Sub-station.

3. Here in this situation, the taps of the transformers at the 132/33 KV Grids were at two

different positions.

4. So the voltage availability as monitored before inter-connection was different.

5. Load availability was also different at the both grids.

6. So during inter-connection at 33/11 KV sub-station, the power was delivered to this station from one of the grid and again some power was going to the other grid. ||www.electricalmirror.net||

Special Column

Smart Meters to change Consumer Behaviour Smart Grids in Smart Cities Smart grids are cornerstone of some of Indian government’s important programs such as 100 Smart Cities, 175 GW of renewable energy by 2022, 40 per cent energy from non-fossil resources by 2030, 6-7 million electric vehicles and 24x7 power supply to all citizen. Smart grid technologies are the key enablers to resolve India’s energy woes, and address troublesome issues such as massive transmission and distribution losses and power thefts. City authorities plan to use IT and automation systems to instrument and integrate all infrastructure and services to optimize the assets as well as use analytical tools to predict demand, usage pattern maintenance, reliability, emergencies and other incidents. In the Indian context where cities do not have a single owner for all their myriad services, it is a Herculean task to integrate all infrastructure and services on a common platform. Extending the available digital platform of one domain (say power) to offer services in other domains (water, gas, traffic, security, pollution and noise monitoring etc) can be a starting point. The smart cities in India can be in two categories – existing cities that should be made smarter by integrating all services on digital platforms; and new green field cities that would be built as smart cities with integrated communication, IT and automation systems. The electricity infrastructure 54

APRIL 2017 || ELECTRICAL MIR ROR

is arguably the single most important feature in any city. If unavailable for a significant enough period of time, all other functions will eventually cease.

DISCOM maintains GIS map of all electrical assets and customers which in effect cover the complete roads and buildings in a city. This is a very useful tool for other infrastructure domains such as water and gas distribution, transport, telecom etc. DISCOM in bigger cities has automated their electrical network with SCADA and DMS. Some of the physical infra of these SCADA/DMS can be shared for automating the water and gas distribution networks as well as managing the traffic and security cameras.

Most of the DISCOMs have state of the art billing and payment collection systems which can be leveraged for collecting the water bills and gas bills as well as house tax etc. Single bill for all utility payments and municipal taxes will be a huge relief for customers.

Also they maintain 24x7 Call Centers in all cities which can be expanded as City Control & Command Centers at marginal cost. Advanced applications such as mobile crew management systems which some of the forward looking DISCOMS are expected to implement soon. Again that platform can be shared with providers of several other services in a smart city. A smart grid addresses three things. First, it modernizes power systems through self-healing designs, automation, remote monitoring and control, and establishment of smart microgrids. Second, it

informs and educates customers about their energy usage, costs and alternative options, to enable them to make decisions autonomously about how and when to use electricity. And third, it provides safe, secure and reliable integration of distributed and renewable energy resources. All these add up to an energy infrastructure that is more reliable, more sustainable and more resilient. Thus, a smart grid sits at the heart of a smart city, which cannot function efficiently without it.

Smart cities depend on a smart grid to ensure pliant delivery of electricity to supply their many functions, present opportunities for conservation, improve efficiencies and, most importantly, enable coordination between city control centre, other infra domain operators and those responsible for public safety. The smart city is all about how the city “organism” works together as an integrated whole and survives when put under extreme conditions.

Energy, water, transportation, communication, public health and safety, and other aspects of a smart city are managed in concert to support smooth operation of critical infrastructure while providing for a clean, economic and safe environment in which to live, work and play. Under extreme conditions, the most critical functions of a smart city would be maintained and logistics information seamlessly coordinated with the public. The smart grid would shed load in a predictable and more manageable fashion so ||www.electricalmirror.net||

that critical city infrastructure and functions are maintained such as police, fire, hospitals, water supply, sewage pumping etc, supported by microgrids.

Self-healing automation would restore power rapidly to areas where alternate routes are available. Local generation would be exploited to support most critical needs. The community (industry, commercial, residential) would respond, automatically, to reduce their energy needs to lessen the burden of restoration.

Transportation and traffic systems would coordinate with the energy systems to support critical transportation arteries and modes. Through it all, timely logistics information would be gathered and supplied to the public by all means available, but particularly through social media networks. Conservation, efficiency and safety will all be greatly enhanced through the availability of accurate logistical information on real time basis. Smart cities, like the smart grid, will evolve slowly, but surely. They will fully harness, integrate and utilize information to be shared between departments, infrastructure operators and with citizens. Cities will partner with vendors to create integrated solutions, and the smart grid will become the part of a greater, more responsive urban ecosystem. Ultimately, with the smart city, we are all in it together.

Indian Smart Cities India is a country in a hurry and the land of opportunities. India’s GDP has jumped from $ 1 trillion to $ 2 trillion in the last 7 years. With a large young workforce in perpetual quest for better jobs and avenues, probably no other country has so much need to create world class infra at a breakneck speed as India has. The Narendra Modi government has given a tremendous boost to build Smart Cities in India by launching the Smart Cities Mission. The Mission has created avenues for major policy reforms and bold decision making to help make massive investments in city infra and making Indian cities smarter.

These Smart Cities would essentially be a combination of converting existing cities into smart cities by a considerable amount of redevelopment, retrofitting as well as through creation of satellite towns around those major cities. The two schemes for Urban Development are: Smart Cities Mission for developing 100 Smart Cities and Atal Mission for Rejuvenation and Urban Transformation (AMRUT) for rejuvenation of 500 towns across India.

Why India Needs Smart Cities India's rapid modernization over the last two and a half decades has essentially centered around cities built long time back. With opportunities remaining limited in rural areas, people are migrating to cities in search of better earnings and life styles. This has resulted in haphazard expansion of areas adjacent to the existing major cities. However with amenities and urban infrastructure always getting overwhelmed by a countless number of people moving in every day, planned development and expansion of Indian cities hardly ever got the due attention it deserved. Additionally, a large number of suburban clusters have also mushroomed in India to cater to the living requirements of people. Till now India could still sustain with whatever band-aid or say incremental development it did for cities. But this approach would not be sustainable in the times to come when there would be an exponential increase in the number of people in India aspiring to live in cities. As per a report by India’s NITI AYOG the Indian cities contribute around 62-63% of India’s GDP which is expected to go up to 75 % by 2021.

Smart Grids Can Be An Anchor Tenant for The Smart City After all, nothing else works without electricity. The design of communications should obviously cater to all Smart Infrastructure of the city. We must take bold steps towards Smart Grids which can provide solutions to Smart Cities. If one were so inclined, how does one eat an elephant? One bite at a time. ISGF along with our members and other key stakeholders conducted 2 brainstorming workshops and prepared Standard Framework for Infrastructure Domains of a Smart City.

We anchor around Smart Grid for the development of Smart Cities in India because digital assets created under various programs can be directly leveraged by other service providers and utilities to build smarter infrastructure. All state owned electricity distribution companies (Discoms) in India are implementing a set of basic IT and Automation solutions under the ongoing R-APDRP scheme of the Ministry of Power. Some of the digital assets created under this program that already covers 1411 towns can be leveraged to build smarter cities at lower marginal costs.

Power Companies Tap Smart Meters to Change Consumer Behaviour Pattern Consumers will soon start getting messages from local power utility companies to switch off an air-conditioner or any other high power consuming appliance to avert a power cut during peak hour. For instance, Tata Power Delhi Distribution Ltd (TPDDL), which supplies power in the north and north-western parts of the national capital region, is set to install smart meters for 20 lakh customers that will detect their usage pattern and help in managing the load. TPDDL has selected Landis + Gyr Ltd., a unit of Toshiba Corp. for building the communication network and to install smart meters on the premises of customers. The investment in smart metering will help the company save 25 MW peak power requirement, said Sinha.

To meet the peak demand in mornings and early

evenings, distribution firms have to get into ‘take or pay’ deals with power generation companies and have to pay a part of the power tariff even if the agreed power is not lifted. With data on usage pattern of consumers, distribution firms will be able to modulate the load and flatten the peak power demand by requesting consumers to use some of their appliance at non-peak hours. A mall, for example, could be requested to switch off some of its escalators for some time, explained Sinha. “Smart metering will facilitate two-way communication between the consumer and the utility, reduce losses and help in delivering better service. It will also help in detecting attempts at tampering with the meter and address the issue of power pilferage. TPDDL is set to make an initial investment of Rs200 crore, which will cover roughly 2 lakh smart meters. The cost will get built into the power tariff to the consumer. For consumers, shifting some of the power consumption to non-peak hours will bring savings as utilities will charge a lower tariff in those hours.

At present, this facility is available to large consumers who use 10 kilowatt per hour (kwh) is expected to be extended to those using 5kwh or more. The company is in discussions with other utilities too to install smart meters and to build the wireless communication network required to operate it. That include Reliance Power Ltd-owned BSES Yamuna Power Ltd and BSES Rajdhani Power Ltd, which supply electricity to about 3.5 million residential, institutional and business consumers in Delhi and some of the state-owned utilities which are able to invest in smart metering. The BSES companies are in the process of covering consumers who use more than 500 units a month by the end of this year in the first phase installing smart metering. The government’s revised power tariff policy announced in January 2016 recommends use of smart meters.

Joined as a GIS Fngineer! Few Facts About SF6 Which you Should Know.

removed by passing through a calcium hydroxide solution in order to neutralize the acids and to form solid sulfates and fluorides.

What if the used SF6 is evacuated in air be any professional ?

What is the limit of quality for SF6 to be used for GIS applications?

Indian Standard for SF6 Handling is - IS 13072 : 2013 / IEC 60376 : 2005 . As per IS 13072 Min Purity Level of SF6 for GIS shall be 99.7% .

We are never allowed to evacuate SF6 in air after use . Evacuation of SF6 to air is a moral and documented crime , we have to handle it as per IEC 61634 (handling SF6), IEC 60480 (used SF6); CIGRE guide for the preparation of customised “Practical SF6 Handling Instructions” [11] .

We purchase 99.9% pure SF6 but later which factors contaminate the same in GIS ( I. e. sealed ) ?

SF6 inside GIS gets contaminated by two way -:

a) Inside arcing :

In GIS during arcing SF6 dissociate, reform and reacts with contaminant O2 and H2O , In circuit breakers, carbon from Teflon® interrupter components, copper and tungsten from contacts and aluminum from shields are typically involved . The bi-products like The SOF4, SOF2, SO2F2, SO2 ,CF4 etc are stable toxics and are to be removed .

b) Outside Air :

One is by incomplete removal of atmospheric gases from the equipment prior to filling with SF6. The other is by ingress through leaks .

As a whole many contaminants such as SOF4, SOF2, SO2F2, SO2, CF4, COS, CO2, WF6, O2, N2, H2O, CCl2F2, and H2 are produced which are to be removed by some purification methodology from SF6 .

What option I have if my SF6 quality gets reduced by 99.7% inspite of using regular filtering units available in market .

If your SF6 quality falls below 99.7% and you are not able to restore its purity inspite of using solutions available in market , you are left with two options .

1) Handover your used SF6 to any government authorised company which can destroy SF6 into non hazardous substances .

2) Find a Purification System in market which is capable of purifying your used SF6 again to 99.9% or 99.99% purity level .You can contact Green-Watt (sales@green-watt.co.in) also for the same .

Query 4 : How to decompose used SF6 gas as per international guidelines ?

The SF6 gas must be destroyed using industrial waste treatment equipment following government guidelines . Indeed, heated at above 1,000°C, SF6 starts to dissociate into reactive fragments, which interact with appropriate partner chemicals, mainly hydrogen and oxygen to form SO2 and HF. The SF6 gas can thus be destroyed with a removal efficiency greater than 99% when the thermal process operates at 1,200°C. The products of the reaction (HF and SO2) are

Curse of Dual Certification for Distribution Transformers

After the enactment of Energy conservation Act 2001, BEE was charged with the prime responsibility of efficient use of energy in variety of equipment particularly in the house hold appliances in a bid to save electricity as per saying that a unit of KWH saved is unit generated. This is of course, true for any equipment being operated on electrical energy.

The efficiency, performance and conservation of energy depend upon quantum of energy losses in the equipment. By reducing the losses, the efficiency can be improved which is the main concern of BEE. Consequently a notification dated February 2009 was issued by Ministry of Power specifying the energy consumption standard under BEE’s S&L programme describing energy losses at 50% & 100 % loading of DTs up to 200 KVA rating units at 11KV level and labeled as star 1 to star 5 having progressively maximum to minimum losses respectively.

Recently BEE has issued an amendment to its February 2009 notification as per No. SO.4062 (E) dated 16th December 2016 effective from 1st January 2017 which has been recommended for extension by another 6 months wherein the losses of Distribution Transformers (DTs) has further been reduced thereby assigning its original star 4 (four) as star 1 (one)and star 5 (five) as Star 2 (two) with further new losses for Star 3,4 & 5 worked out by extrapolating. The transformer manufacturers are already producing and supplying new Star 1 (one) transformer as per the requirement of the purchasers.

The efficiency of any equipment i.e. say Distribution Transformer can be worked out as output in KW divided by sum of output and losses at a specified load and temperature. For energy efficient transformer design, superior grade active core material and copper winding are necessary to get the lower losses, greater reliability and reduced heat output i.e. less carbon emission. Lower losses are most suitable from the point of techno-economical electrical distribution system.

The maximum efficiency of Distribution Transformer is when no load losses are equal to the load losses which is not at all adoptable economically. In a rough calculation of 100 KVA Distribution Transformer, the efficiency at 100%, 75%, 50% & 25% loadings at unity power factor at fixed no load losses varies between 98.0% to 98.5 % but with power factor of 0.8 the efficiency is again affected by about 0.20% which can be exactly computed by the designer of the transformer. Incidentally, in contrast the efficiency of power transformer rather large power transformer, the efficiency level is very as high as 99.75% as the 60

APRIL 2017 || ELECTRICAL MIR ROR

designer has to keep the fixed losses of core and variable load losses in optimum ratio generally between 1: 3 to 5 and lower the ratio the most economical operation of the power transformer can be obtained. The designer has to consider such aspects based on the given technical specification and operational duties the unit has to perform during its life time.

It is very well known that 95% of the distribution segment is controlled by State Governments Discoms / Utilities and Electricity Boards, where political interference is not ruled out and is responsible for lot of ills of distribution companies. One of the major concern of the authorities was very high failure rate of Distribution Transformers since the turn of the country. Inefficient and bad quality of Distribution Transformers cause 4 to 5 % of losses in the distribution network. In this connection CEA, the Apex organization of Ministry of Power in consultation with experts of transformer manufacturers worked out detailed technical document and issued guidelines for specification of energy efficient outdoor type three phase and single phase distribution transformers in 2008 specifying all technical parameter of losses including at 50% and 100% loading, raw material, insulation level, testing, inspection, manufacturing, procurement and installation etc. to be followed by all Discoms/Utilities at National Level, even when the prevalent IS:1180 /1989 did not specify the losses in the standard. In fact all Discoms/Utilities were specifying their own set of losses at no load and full load and the other parameters while issuing tenders for procurement of transformers.

Accordingly all the transformer manufacturers dutifully started implementing the mandatory BEE’s S&L programme to produce star 1 to 5 energy efficient DT s for the power sector after completing the necessary formalities of BEEs regulation and obtaining certification for labeling the DT star 1 to star 5.

Concurrently CEA in its notification dated August 2010 issued technical standard for construction of electrical plant and electric lines regulation for Distribution Transformers that: “the maximum losses of oil filled DTs shall not exceed as that for at least 3 star transformer specified by BEE wherever applicable”.

Till 2009 the Distribution Transformers were being manufactured and used as per specification of IS:1180/1989 which was under revision for the last number of years and was finally notified in 2014

as IS:1180/2014 (part-2) after 15 years under 4th revision encompassing losses for 50% & 100% up to 2500 KVA rating at 11/22/33 KV as level 1, 2 &3 equivalent to BEEs star 3,4, &5 thereby necessitating amendment of CEAs technical standard for construction of electrical plant and electric lines through notification in 2015 as under: “The maximum losses of oil filled DTs shall be as per relevant Indian Standard i.e. IS: 1180 /2014 (2014)” It may be noted the quality of any product is a prime concern even at the highest level of Hon’ble P M who had declared a slogan “Zero defect, Zero effect” and implored on the industries not to compromise on product and environment in his address to the Nation from the rampart of Red Fort on 15th August 2014 the Independence Day. Such like pronouncements were repeated by others including Cabinet Secretary in International industrial fathering for attracting foreign investments coupled with lot of incentives for doing business with ease under ‘Make in India’ schemes which in fact is pet subject of our Hon’ble P M. Even Ministry of Heavy Industries and Public Enterprises (DHI) issued a quality control order on Electrical Transformer in 2014 for manufacture/use of DTs in accordance with IS:1180/1989 up to 100 KVA rating at 11 KV level which was subsequently amended in 2015 mandating the manufacture/sale & use up 2500KVA at 11/22/33/ KV as per revised IS:1180 Part 1/2014 effective from 1st February 2016 duly BIS marked only.

It will be thus observed that the manufacturers of DTs have to obtain dual certification from BEE & BIS for energy efficient DTs under IS:1180 Part 1/2014.

Now there is a conflict, the manufacturers are requesting Govt. of India to allow them the compliance of one of the `authorities/ agencies directive i.e. BIS or ||www.electricalmirror.net||

BEE for the same goal of producing Energy Efficient DTs, and should not insist upon as in both the cases, they have to manufacture Energy Efficient Distribution Transformers as per only one standard IS:1180 Part 1/2014.

But Ministry of Power has shown its helplessness as in both cases it is mandatory through Gazette Notifications, which obviously is not desirable as manufacturer has to observe and complete, all the formalities/ requirements of both the agencies which not only create hindrance in conducting the business with ease but also involves lot of time and expenditure of yearly renewal of licence and hefty BEE’s labeling/BIS marking fees of each types of distribution transformer produced. Besides the suggestion shall save the administrative work of one of the Govt. Agencies. ITMA has requested to PMO to intervene, vide its letter No. ITMA/11/2016 dated 13th October 2016.

The PMO has forwarded the representation to MoP who has given stock reply that the matter has already been decided by Hon’ble Union Power Minister indirectly intimating that the transformer manufacturers shall have to comply with the requirements of both the agencies with slight concession which is insignificant and of no consequence.

The transformer manufacturers are not satisfied and again made representation to Hon’ble Union Power Minister to re-examine the issue and appreciate all the aspects dispassionately in order to give relief to the stakeholders, so that they are able to do the business with ease which slogan is hallmark of the present day Govt. of India and finds special mention in the current budget.

In the representation the following point have been stressed/highlighted for rendering justice to the transformer industry at National Level.

1. The DTs have to be manufactured, supplied and purchased only as per IS 1180 Part 1/2014, for BIS & BEE. 2. In fact BEE follows all the testing procedures as laid down by BIS in their Standards 3. All the testing procedures to be followed for taking certification for any size/rating from BEE and BIS are the same.

4. BEE having only one central office in Delhi is

controlling whole Indian Transformer Industry, whereas BIS has got its own Regional and Zonal offices across India thus leading to a more efficient working.

5. BEE Charges Rs 100/- per transformer irrespective of size of the same. BIS Charges Rs 3 per KVA per job. e.g. for a 16 KVA Job BEE would take Rs 100/- per job and BIS would take 16 KVA x Rs3 = Rs 48/- per job and on the contrary for a 200 KVA Job BEE would still take Rs 100/- but whereas BIS would take 200 KVA x Rs3 = Rs600/- per job. This double marking fee is ultimately a burden on State Utilities or private customers.

6. Till 31.12.2016 scope of BEE was limited from 16 KVA to 200 KVA 11 KV Class Transformers and BIS upto from 6.3 KVA to 2500 KVA 11, 22 & 33 KV Class including single phase transformers as well. Since 01.01.2017 scope of BEE has been raised from 16 KVA to 2500 KVA, 11 KV Class Transformers. BIS has much wider scope as compared to BEE. 7. Till 31.12.2016 Transformer Losses of BEE 3 Star, 4 Star & 5 Star Transformers were equivalent to those of Level 1, Level 2 & Level 3 Transformers as per BIS respectively.

8. From 01.01.2017 as per new table in notification Dt 16.12.2016 of BEE, 1 Star and 2 Star transformers losses now stand equal to the losses of Level 2 & Level 3 Transformers as per BIS. 9. BEE is only concerned with end results of transformer like losses whereas for a transformer to be certified by BIS the manufacturer has to take care of all the raw materials also which need to be of a particular standard or BIS certified as defined by BIS. It would be appreciated from the above comparison of requirements between BIS & BEE ultimate rigmarole of BIS is the main nucleus which takes care of BEE as well. As such one agency which enforces rigorous requirements should be opted.

It has been emphasized time and again that BEE’s star labeling programme is generally for household items which helps in awareness of consumers before purchase of energy efficient electrical appliances/ equipment from the open market as the consumer

has no means to check the quality/ efficiency of the product and therefore he could mainly rely on the star label provided by manufacturer on the basis of BEE's certification. Whereas the DTs are not a consumer item but a capital goods item being procured/used by the Govt. utilities/discoms and EPC contractors as per the approved technical specifications contained in tender documents as per IS:1180 Part 1/ 2014 and are supplied by the manufacturers only after inspection and testing of the transformer at the works of the manufacturer which are also being tested separately at the BIS recognized Test Laboratories before supply.

It is prudent to note that one equipment i.e. DT is required to be manufactured as per IS: 1180 Part 1/2014 but has to be certified by two agencies i.e.

BEE and BIS for the same goal for providing Energy Efficient DTs as per the notifications in vogue.

In view of the forgoing Ministry of Power is again requested to look into the matter and consider the applicability of only one of the agencies for mandatory certification of DTs for manufacture and supply of quality energy efficient DTs as per IS:1180 Part 1/2014 which will afford the manufacturers to deal with only one agency for doing the business with ease. Besides this will further have following benefits and thus will reduce wastage of time and money.

(i) To save establishment charges of one of the Department of Govt. of India. (ii) To save the drill of transformer manufacturers staff to attend to the requirements of BEE & BIS. (iii) To save additional expenditure of transformer manufacturers by way of registration fee, marking/labeling fee for each unit of transformer produced/ manufactured. (iv) To save the transformer manufacturer from carrying out drill of getting renewal of registration separately with BIS & BEE by incurring hefty fee.

In the end, the Ministry of Power is requested to re-consider to do justice in order to mitigate the hardship and harassment of the transformer industry.

Ther is a conflict, the manufactures are requesting Govt. of India to allow them the compliance of one of the authorities/ agencies directive i.e BIS or BEE for the same goal of producing Energy Efficient DTs, and should not insist upon as in both the cass, they have to manufacture Energy Efficient Distribution Transformers as per only one standard IS:11800 Part 1/2014...

Power Quality: A Growing Concern The modern power distribution grid is changing rapidly and these changes can be expected to have an impact on power quality, which is the concept of powering sensitive equipment in a manner that is suitable to the operation of that equipment. In the short term at least, the impact is likely to be negative, with power quality problems becoming more rather than less troublesome.

The power grid is being forced to change as the result of not one but many simultaneous developments.

These include the growing need to connect green energy sources, such as wind and solar power, and the steady reduction in the number of traditional bulk generation plants that rely on fossil fuels as their energy source. Loads on the grid are also changing, with new technologies like electric vehicles leading to an even greater demand for power and a shift in the hours of peak demand. To help address these changes, smart-grid technology, designed to make the grid more efficient and more flexible, is being introduced.

It might be tempting to think that the spread of smart-grid technology will alleviate power quality problems, with a consequent reduction in the need for power quality investigations. Unfortunately, this isn’t the case. A primary objective of the smart grid is to increase the reliability of power delivery – it is unlikely to have any significant impact on the quality of the power being delivered. In fact, the new types of loads and sources continually being added to the grid will inevitably create new power quality challenges.

Some of the most common power system fluctuations impacting power quality include under- and over-voltage, dips (sags) and swells, transients, unbalance, flicker, harmonics and rapid voltage changes. To help readers refresh their understanding of power quality and to stay up to date with the latest thinking, we are currently preparing a series of articles, starting with the fundamentals of PQ and progressing to topics such as what is a Class A recording, transient and harmonic impacts on motors & transformers, energy fundamentals, and the truth about energy saving devices. The first of these timely ||www.electricalmirror.net||

and well informed series of articles will appear in the next edition of Electrical Tester and will look at the foregoing types of power system fluctuations, explaining why and how they occur, examining the effects they have on the power distribution network and on loads, and discussing how they can be measured and evaluated.

Megger has been working extensively to address these concerns and with its latest innovation – MPQ1000 and MPQ2000.

The MPQ1000 is in compliance with IEC61000-4-30 Class A and is rated CATIV at 600V. It can be used for a wide variety of applications including substation monitoring, equipment and breaker tripping, load studies and load balancing as well as for switchgear and component failure.

This highly intuitive unit delivers unmatched capability in a smart ergonomic platform. In both the scope and DVM modes, the versatile MPQ1000 can record power, energy, RMS, sags, swells, transients down to 1 microsecond, harmonics, inter-harmonics, harmonic direction, THD, TDD, flicker, unbalance, rapid voltage change (RVC), mains signalling, phase angle deviation, as well as performs waveform analysis to the 128th harmonic in real time.

Data gathered during testing can be recorded with the MPQ1000 record verification by simply pushing a button. This feature automatically detects the current clamps, recognizes its range, identifies the nominal voltage and sets the triggers, as well as verifies that the unit is connected properly to what it is testing.

The MPQ1000 unit also features flexible current clamps that have four selectable ranges from 0 to 6000A. The MPQ2000 Megger Portable Power Quality Analyzer, with its latest software and enhanced capabilities, addresses the international IEC61000, IEEE1159, IEEE519 and EN50160 series of power quality and delivery standards used around the world.

The unit can be left at remote locations and data can be viewed from the user’s locations at the convenience of the user.

The analyzer comes equipped with self-identifying, four range flexible current clamps which are powered by the unit. No batteries are required. Additionally, the analyzer comes equipped with real-time scope and DVM modes. View RMS data, wareforms, demand data, phase angles, vector diagrams, harmonics, interharmonics, unbalance, flicker, and more in real time.

When data needs to be recorded, the MPQ2000 record-verification feature automatically identifies the current clamps being used, recognizes the range they are in, and verifies the unit is connected properly. The analyzer verifies that all voltage and current connections are correct prior to the start of the recording. This eliminates the possibility of the recording of “bad” data.

From utilities, to commercial and industrial, to residential monitoring, the MPQ2000 is your comprehensive intuitive tool for analyzing and solving power quantity and power quality problems.

Danish CHP Station 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 PR’s 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 Danish households and industries, including horticultural greenhouses. Today the station is one of Europe’s largest electricity producers.

Danish CHP Station 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 agreed to do a PR TC converter test set-up.
