In Kuhn’s view, the scientific advancement is not evolutionary, but rather is a “series of peaceful interludes punctuated by intellectually violent revolutions”, and in those revolutions “one conceptual world view is replaced by another”.

EDITORIAL Dibyendu RoyChowdhury

Electricity, which is largely a product of 18th and 19th century scientific and engineering developments, has encountered anomalies which cannot be explained by the universally accepted paradigm. It has evolved like no other. The industry has been changed from one way of thinking to another. It’s a revolution, a transformation, and a sort of metamorphosis.

And the transformation just didn’t happen; the transformation is driven by innovation.

From here, the industry is also leaning towards nuclear power. India aims to supply 25 per cent of its electricity from nuclear power by 2050. Not only in India, nuclear is going to be a key element of global energy mix because nuclear power provides competitive energy without disturbing the climate.

Change is the way of life, as Kuhn wrote, “Successive transition from one paradigm to another via revolution is the usual developmental pattern of mature science.” Synchronising with this gradualist model, the power industry has been evolving and will continue to do so.

Power Update Piyush Goyal calls for building SAARC Power Grid Shri Piyush Goyal, Union Minister of State (I/C) for Power, Coal, New and Renewable Energy has called for building SAARC power grid so that excess production of power in one region can easily be used to meet deficit elsewhere. Goyal was addressing the inaugural session of the 5th meeting of the SAARC Energy Ministers.

ranging from healthcare to education to employment opportunities. The household per capita consumption of electricity within SAARC is mere 128 units versus global average of 3,045 units. Goyal called upon all member countries to take this as a challenge and we all should commit over selves for pushing up household per capita consumption.

ACME wins 160 MW project tender

Goyal said “Rivers can flow only in one direction, but power can flow in the direction of our choice! I dream of a seamless SAARC power grid within the next few years. For example : Hydroelectric power generated in North East India could be transported via Bangladesh, India and Pakistan, on to Afghanistan or offshore wind projects could be set up in Sri Lanka’s coastal borders to power Pakistan or Nepal. The possibilities are limitless.”

ACME Group, India’s leading solar power player in India has announced that it has emerged as the largest successful bidder amongst 51 bidders for 160 MW solar PV power projects at the 500 MW tender opening ceremon at Hyderabad under RFP floated by Southern Power Distribution Company Limited of Andhra Pradesh (APSPDCL). As per the terms and conditions of the bidding document, the selected developer would sign 25 year long PPA with AP Discom on bided tariff.

The Power Minister further stated that the economic sustainability of SAARC region is pillared on energy security as 30 per cent of the region’s energy demands are met through imports. In order to resolve this, Goyal advocated a three pronged strategy by leveraging harnessing conventional and renewable sources of energy, building inter-connected transmissions grids and forging efficacious power trading agreements. SAARC is a robust market but constraints are primarily on the supply side as there are pockets where deficits persist, Goyal said.

Commenting on this occasion, Manoj Kumar Upadhyay, Founder and Chairman, ACME Group said, “This win is the country’s largest win by any private solar developer. It is a testimony to the prowess of ACME Group and further strengthens our emergence as the leading solar power producer in the country. With this addition, our solar power portfolio has reached 422.5 MW and we are on way to generate 1000 MW by year 2017.”

Highlighting the correlation between per-capita electricity consumption and Human Development Index (HDI), Goyal said that the impact of electricity on human lives is profound

This project would entail an estimated investment of $ 210 mm/ ` 1250 crores. The project will increase its solar portfolio to 422.54 MW. The 160 MW projects would be set-up in the three districts of Anantpur, Karnool and Chittoor in Andhra Pradesh.

Alstom T&D India wins second grid contract from Power Grid €17 million (` 1380 million), to supply transformers and reactors for the expansion of 400/220 kV grid substations across southern India. The project is part of Power Grid’s System Strengthening Scheme to boost power handling capacity of substations, and stabilise the transmission infrastructure in southern India.

Alstom T&D India has secured a contract from Power Grid Corporation of India Limited (PGCIL), for approximately

November 2014

Under this new contract, Alstom will supply six units of 400/220kV, 500MVA transformers and two units of 420kV, 125MVArshunt reactors. All equipment will be supplied from Alstom T&D India’s manufacturing facilities across the country.

This is Alstom’s second win to strengthen the country’s transmission infrastructure under the System Strengthening Scheme. The first power transmission reinforcement contract was awarded in July 2014 to expand 400/200 kV grid substations across eastern India.

Rathin Basu, Managing Director of Alstom T&D India, said, “Winning a second project under the System Strengthening Scheme is a major achievement for Alstom, confirming our industrial expertise and leadership. We are delighted to continue contributing to the development of India’s national grid infrastructure.”

Power Update India’s energy problems can be solved within 18 months says Suresh Prabhu India can solve its energy problem within 18 months by putting in place thermal capacity of about one lakh mega watt (mw), which is lying incomplete and blending it along with about 2, 50,000 mw capacity available currently, said Suresh Prabhu, chairman, Advisory Group for Integrated Development of Power, Coal and Renewable Energy at an ASSOCHAM event held at New Delhi.

Terming financing as an extremely challenging issue being faced by the renewable energy sector, Prabhu said, “We need $7.5 billion of equity and $22.5 billion of debt and to make that happen we need to put in some sort of an instrument in place.”

He suggested that the Government should transfer the clean energy cess worth ` 100 per tonne being collected from Coal India to the Indian Renewable Energy Development Agency (IREDA) as they could leverage this by nine times as part of capital adequacy norms for non-banking financial companies (NBFCs).

“So if we give them something like ` 20,000 crore they could easily have another ` 1,80,000 crore which they can borrow from the market because 1:9 is possible for them as NBFCs could leverage the capital by nine times and this is something which they should be doing by using IREDA more effectively,” said Prabhu.

He also said that use of tax as an instrument to discourage non-renewable energy is undesirable for India as it would push the energy costs upwards. On the issue of making states to take up the responsibility for switching to renewable energy, Prabhu said that there is a need to enforce the RPO (Renewable Purchase Obligation).

Power Update Madhya Pradesh gets new power generating unit Bharat Heavy Electricals Limited (BHEL) has achieved yet another landmark by successfully commissioning a 600 MW thermal unit in Madhya Pradesh. The unit has been commissioned at Madhya Pradesh Power Generating Company Limited’s 2x600 MW Shree Singaji Thermal Power Project, located near Dongaliya village of Khandwa District of Madhya Pradesh. Earlier, the first unit at the same power project was commissioned by BHEL in November, 2013 and is running as per grid requirement.

BHEL’s scope of work in the contract covered design, engineering, manufacture, supply, erection and commissioning and civil, structural and architectural work of main power block equipment broadly comprising of steam turbines, generators, electrostatic precipitators and boilers along with associated auxiliaries and electrical besides state of the art controls and instrumentation. This in-house engineered 4-cylinder 600 MW rating TG sets establish the engineering prowess of BHEL. Currently, the 500 MW sets, earlier supplied by BHEL, form the backbone of the Indian power sector and have been performing much above the national average as well as international benchmarks. BHEL has so far contracted 21 sets of 600 MW rating, out of which nine sets have already been commissioned. These sets have a very high level of indigenization. A large number of similar rating sets ensure easy availability of spares and operator’s familiarity. BHEL has a share of more than 90 per cent in the thermal generating capacity of the state utility in Madhya Pradesh.

Power Update TERI’s solar lighting laboratory receives NABL accreditation The Solar Lighting Laboratory (SLL), which was recently set up

by The Energy and Resources Institute (TERI) in New Delhi, will be the first laboratory in India to receive accreditation from the National Accreditation Board for Laboratories (NABL) for IEC 62257-9-5 standards, applicable to standalone lighting for rural electrification.

The laboratory adheres to International Electro-technical Commission (IEC) (IEC is an international body that sets standards for all electrical, electronic and related technologies throughout the world) standards for the testing of solar lighting systems (SLS), and has been recognised under the Lighting Global programme of International Finance Corporation (IFC). The laboratory is supported by the Ministry of New and Renewable Energy (MNRE), Government of India.

It is working towards strong quality assurance and testing programmes, which will help in building consumer confidence towards solar lighting products.

Export led growth for electrical equipment in Q1, 2014 The Indian electrical industry has witnessed a marginal production growth in the first quarter of 2014. While on the other side the industry has witnessed a turnaround in growth for HT Motors, Power Transformer and HT Switchgear (mostly in MV segment). The growth in TLT, Transformer, and LT Capacitors is largely driven by Exports growth.

Dr Leena Srivastava, Executive Director, TERI, and Vice Chancellor, TERI University, said: “We are proud to receive this recognition from NABL and feel privileged to be able to offer yet another service in support of sustainable development.

Awareness on lighting quality and needs as well as on the life-cycle economics of different products is extremely poor in the regions where these are needed most.”

The Indian Electrical and Equipment Manufacturers’ Association (IEEMA) represents 800 power companies involved in power generation, transmission and distribution equipment contributing to 90 per cent of the power equipment installed in India. As per IEEMA data findings: the Cable product line is the largest growing sector (28.7 per cent). Its turnover stands at ` 29,000 crore which is highest among the product lines and the growth in Cables is largely from Low Voltage and Light duty cables, which is being driven from Distribution product requirements coming in from DISCOMs and private players.

As of now, the laboratory has tested more than 170 models of solar lighting systems including solar lanterns, solar home lighting systems, solar task lights and multi-purpose solar lights. The laboratory is unique as it caters to the testing needs of both rural as well as urban lighting infrastructure.

“Growth in Q1 2014 is encouraging; however the industry is uncertain of sustainability of the growth in medium term. The Indian electrical equipment industry size in 2013-14 was in excess of USD 22 billion, with exports of USD 5 billion,” said Mr Vishnu Agarwal, President – IEEMA.

Power distribution loss still high across many states ICRA has observed an improvement in distribution loss levels for discoms in 12 states in the period FY 2007 - FY 2013 while a deterioration or limited progress in reducing loss levels has been seen in five states and in the remaining two states, loss levels have remained almost unchanged. Despite this improvement, the distribution losses remain relatively high in a majority of the states - with discoms in 10 states showing losses higher than 20 per cent loss in FY 2013.

Discoms which have seen a deterioration or limited progress in reducing loss levels are in the states of Uttar Pradesh,

14

November 2014

Jammu & Kashmir, Bihar, Chhattisgarh and Odisha – where the loss levels in FY 2013 remained significantly higher as compared with the national average.

ICRA estimates average all India AT&C loss levels in the range of 27 per cent for FY 2013. This is significantly higher than what is targeted and points to a considerable scope for reduction in loss levels.

The distribution segment of power sector is predominantly state owned and the private owned distribution utilities account for about 7-8 per cent of the energy demand in the country.

As against the state-owned utilities, operational efficiency levels for most of the private owned distribution utilities have remained relatively better which is largely on account of favourable demographic profile with limited mix of agricultural consumption, implementation of adequate capex for strengthening of distribution network and better operational focus and practices followed.

aradigm shift, an enigmatic concept, was coined by Thomas Kuhn in his book “The Structure of Scientific Revolutions” (1962) to describe revolutionary changes in technology.

The power sector, which has evolved like no other, has encountered anomalies which cannot be explained by the universally accepted paradigm within which the industry progress has thereto been made.

Power industry over the years Electricity is largely a product of 18th and 19th century scientific and engineering developments. The US was the first country that generated electricity followed by UK. In India, the credit goes to CESC Ltd., which started power generation and distribution in Kolkata in 1899.

PARADIGM SHIFT The way the power industry has evolved, transforming standard, expected, or popular beliefs

The Indian power sector has been regulated for almost a century. The Electricity Act 1910 was the first of its kind to govern the Indian power sector. Post-independence, India created State Electricity Boards (SEBs) to entrust the development of the electricity sector in respective states; however, SEBs fared miserably.

After the poor operating performance of SEBs, India set up two central sector utilities: NTPC (National Thermal Power Corporation Ltd.) for thermal generation and NHPC (National Hydro Power Corporation Ltd.) for hydro power.

India also recognised that electricity and other infrastructure sectors required substantial investments.

Prior to this, the electricity sector was mostly in the hands of SEBs or central government owned utilities.

Since then, India developed institutions of independent regulation, initiated guidance and direction of reform efforts, took legal initiatives to bring in competition, and offered programmes to effectively procure power on a long-term basis on behalf of state governments.

Game-changing movements The year 2003 marked a new beginning of reforms in the electricity sector in India with enactment of the Electricity Act. The power industry saw a series of regulatory changes after the enactment of the Electricity Act in 2003 which have opened up and driven the power generation sector on a high-growth trajectory.

Over the past few years, the Government of India has undertaken several legislative measures and carried out extensive policy reforms — including National

The energy cost is going to rise significantly, and solar energy will be competing in this context.

Arul Shanmugasundaram, Executive VP (Projects) and CTO, Tata Power Solar

“The focus is on energy generation and making solar more accessible,” says Arul Shanmugasundaram, Executive VP (Projects) and CTO, Tata Power Solar. “Gallium nitride based inverters is one of them.”

According to Giancarlo Chiapparoli, Business Development Manager, Bonfiglioli Renewable Power Conversion India, the future innovation will focus on next-generation modular inverter design, outdoor inverter station, advanced grid integration features, and battery-based solar plant applications.

Trends to keep power industry moving Tariff Policy, National Electricity Plan, Competitive Bidding Guidelines, and Ultra Mega Power Projects — to accelerate the growth of the power sector and encouraging greater private participation.

Now the government has also allowed 100 per cent FDI in generation, transmission and distribution segments as well as exempted duties on capital equipment under the Mega Power Policy.

Expected technical innovations The solar industry is on the rise, and the cost structure change in the solar industry is itself a blessing to the industry.

Nuclear, not only in India, remains a key element of countries’ energy mix as it provides low-carbon, competitive energy and guaranties energy security of supply.

“Going by the India’s emerging solar policy, the thrust is on utility scale project in the next 5 years,” points out Hitesh Doshi, Chairman and MD, Waaree Group. He has a valid point.

Almost 3,000 MW of projects have been announced under various state tenders, and the government is pushing the big conventional energy players to participate in solar.

Even Shanmugasundaram thinks so.

“One has to look at the solar industry from the perspective of overall electricity or energy industry,” he explains. “The energy cost is going to rise significantly, and solar energy will be competing in this context.”

He also thinks that the major trend in power will be the cost of solar power which is going to come down. “In terms of generation, it is also getting closer and closer to imported coal,” he adds.

“Overall adaptation of solar power will have significant growth, especially in India.”

According to Sanjeev Ranjan, MD, ICAI, the new trends are clean energy generation and lesser dependence on fossil fuel, integration of renewable in the grid to manage the variability of power generation, energy storage, and small grid. He also believes that reduction of T&D losses as well as strengthening the regional power grid

network will be also a trend in India.

Power industry in future

It seems the nuclear power will be the future for India, which currently operates 21 atomic reactors which produce 4,780 MW of electricity and aims to supply 25 per cent of its electricity from nuclear power by 2050.

“We believe that there is great potential both for nuclear and renewable energies in India because the country has to satisfy an already huge energy demand which is anticipated to significantly grow in the coming years and decades,” explains Tarik Choho, Chief Commercial Executive Officer, AREVA Group. “An average of 16 GW additional power generation capacities is required each year until 2020 to meet the country’s fast-growing electricity demand.”

Choho adds, “Nuclear, not only in India, remains a key element of countries’ energy mix as it provides low-carbon, competitive energy and guaranties energy security of supply.”

Even Shah Nawaz Ahmad, Senior Adviser - India, Middle East and South-East Asia; World Nuclear Association, believes that India has the manpower and skills to accelerate the nuclear power sector. He explains, “The indigenous programme, covering the three-stage programme, appears to be on track.

Indian authorities remain committed to the programme. The new government has also shown continued commitment to both aspects of the programme, both indigenous and imports.”

With many bilateral nuclear agreements in place, India is expected to become a major hub for manufacturing nuclear reactors and associated components. However, India needs to meet its environmental and climate change commitments while ensuring the country’s energy independence and security of supply.

Today the company provides services to 346 of the 435 operating nuclear reactors and to more than 95 per cent of the nuclear utilities. In an exclusive interview with EPR, Tarik Choho shares why nuclear power remains a key element of India’s energy mix.

How has the nuclear power sector evolved since AREVA started its journey in India?

AREVA has already completed the installation of five biomass plants in India, totalling more than 47 MW of generating capacity. We are committed to continuing to support the development of renewable energies in India as part of the answer the country’s ever-growing electricity demand.

As for nuclear, France and India signed a Nuclear Cooperation Agreement in 2008, and AREVA and NPCIL signed a MoU in February 2009 for a partnership in nuclear power generation to build up to six EPR reactors at Jaitapur site in Maharashtra and provide lifetime fuel supply for these units. A General Framework Agreement (GFA) was then signed in December 2010 for the construction of the first two EPR reactors and supply of fuel. Commercial negotiations are now ongoing.

All around the world, the challenges remain the same: answer to an evergrowing electricity demand while ensuring energy independence and security of supply, providing affordable electricity and maximising low-carbon energy developments to meet their environmental commitments. Nuclear

and renewable energies are the two key elements of today’s energy mixes.

Nuclear power contributes less than 3 per cent of India’s total energy generation. Where do you see the future of nuclear power in India?

We believe that there is great potential both for nuclear and renewable energies in India because the country has to satisfy an already huge energy demand which is anticipated to significantly grow in the coming years and decades. An average of 16 GW additional power generation capacities is required each year until 2020 to meet the country’s fast-growing electricity demand. However, despite substantial capacity additions, India’s power sector is still in shortage of energy with peak demand shortage averaging 12 per cent. Besides, India, just as many other countries, has to meet its environmental and climate change commitments while ensuring the country’s energy independence and security of supply, and offering its citizens affordable electricity.

As such, nuclear, not only in India, remains a key element of countries’ energy mix as it provides low-carbon, competitive energy and guarantees energy security of supply.

India, which over the last decades, has built 21 nuclear reactors and grown a pool of excellent scientists and experts which clearly underlines the country’s interest for this source of energy.

Committed to further developing its nuclear programme, India, as mentioned above, signed with France a Nuclear Cooperation Agreement in 2008 and AREVA and NPCIL signed a MoU in February 2009 for the construction of up to six EPR reactors at the Jaitapur site (Maharashtra) and the lifetime supply of fuel for these units.

Electrical & Power Review

Nuclear India has been a precursor and has announced nuclear capacity targets of 27,500 MW by 2032 with the aim to supply 25 per cent of its electricity from nuclear power by 2050. Prime Minister Narendra Modi also has reaffirmed the country’s commitment to nuclear energy since his arrival to the ministry.

We are very confident that nuclear power will grow substantially in India in the future.

The aftermath of Fukushima has raised many questions about nuclear power. Is nuclear power with its attendant waste and safety issues worth having?

The Fukushima accident raised legitimate concerns, and the nuclear industry has responded to ensure that all the lessons in nuclear safety are and will continue to be learned from it. Post Fukushima, safety checks were conducted throughout the world, including by European Safety Authorities on AREVA’s technology.

They all confirmed that the EPR design meets all the revised safety standards, especially to handle combination of hazards, including core melt situations.

The fundamentals of the nuclear market remain the same, and the Fukushima accident does not call into question the growth of nuclear energy.

The challenges are still to answer to the growing demand for energy and electricity while maintaining energy independence, security of supply and meet climate change obligations. Twice as much electricity will be needed by 2050, but with half as much CO2 to maintain today’s earth’s equilibrium.

There are currently more than 70 nuclear reactors under construction around the world. The International Energy Agency (IEA) predicts in its World Energy Outlook 2013 that nuclear capacity will increase by about 47 per cent by 2035 to maintain its 12 per cent share in the world’s electricity consumption.

GW of new nuclear generating capacity must be added annually by 2050. Much of this growth is expected in India and China which aims for a four-fold increase in nuclear capacity to at least 58 GW by 2020.

At least 36 new nuclear reactors are planned or proposed in India. What is the status of discussions between AREVA and NPCIL? Following the Indo-French Nuclear Cooperation Agreement signed in 2008, AREVA and NPCIL signed MoU and General Framework Agreement (GFA), respectively in February 2009 and December 2010 for the construction of the first two EPR reactors in Jaitapur.

AREVA is now eagerly looking forward to launching the early works and to reach an agreement with NPCIL on all technical and commercial terms of the contract.

As per Civil Liability for Nuclear Damage Bill, 2010, India’s liability regime also holds suppliers accountable. Is it going to affect the foreign investment?

Regarding the Nuclear Civil Liability Act and its implementation rules, it appears that some clauses of the law are open to various interpretations. We are calling for a clarification and expect that once the provisions are clarified, a legal framework acceptable for suppliers, like AREVA, will be defined.

We believe that governments have a key role to play in nuclear development by supporting the right conditions to develop those projects like the UK Government did with the reform of its electricity market and the implementation of the Contracts for Difference in order to encourage private investments in new nuclear electricity generating capacity developments. It is clear that for India the Civil Liability for Nuclear Damage Bill, 2010, has to be managed.

Even Indian nuclear suppliers have pointed out that the act was a major obstacle for them and have requested

more clarity and some amendments to be made on the law. It might have discouraged some of the investors, but we are confident that a solution can be found.

AREVA covers every stage of the fuel cycle and nuclear reactor design and construction. How the company has been innovating?

Innovation is one of the core values at AREVA as we constantly strive to achieve excellence in all aspects of our value chain and to always best answer our customers’ needs. AREVA has, therefore, set up several programmes to encourage innovation because, for the group, it is a condition for the development of our activities and to maintain a competitive edge.

AREVA provides services to 346 of the 435 operating nuclear reactors and to more than 95 per cent of the nuclear utilities by notably anticipating evolving needs for the nuclear installed base: lower to higher fuel burn up, all operations from reactor commissioning to maintenance as well as lifetime extension. Following Fukushima, AREVA launched the innovative “Areva Safety Alliance” program which offers nuclear utilities the most advanced products and services to help them demonstrate and optimise the safety of their nuclear power plants through the end of operations. A year later, the group launched the “AREVA Forward Alliance” program dedicated to safe long-term operation and life-time extension of nuclear power plants. To complete the offer, AREVA will launch by the end of the year the “AREVA Value Alliance” program offering utilities solutions to improve plant performance and profitability.

Our products constantly evolves, incorporating optimisations and innovations from the previous nuclear reactor generation and with continuing integration of lessons learnt from projects currently under construction.

When the utility fails, the solar can still deliver maximum power with the rest shared by the back-up diesel generators. Considering the significantly long hours of utility failures, this is a boon to installations that have sizeable solar capacity.

DEIF makes this seamless integration possible with its intelligent controllers interfacing with solar inverters and diesel generators by controlling the power flow in the circuit intelligently.

They maintain sufficient reserve capacity to meet heavy consumers and also handle any fall in solar output with diesel power. This clever combination can increase green power in the system, increase reliability of power and also save money with less fuel usage.

DEIF expects to see more from the solar segment, and there is a vast scope to provide power management solutions for this sector.

Expected technical innovations DEIF believes that its innovations come from its customers and their needs.

As a group, “leading innovation” is its strategic focus area. Nearly 20 per cent of its employees are working in R&D, and DEIF wants to further strengthen this with more PhD projects and association with universities for research and development. The company sees endless opportunities in hardware, software, communication, remote monitoring and control in its field.

Shifting wind in favour GE’s newest innovation that matters to India’s low-wind speed conditions

T

echnology doesn’t care about tradition; technology cares only about innovation. When you look at General Electric (GE), you are bound to care about both. You have to remember that GE is the grand daddy of all the technology companies. However, GE is not only about tradition or innovation; GE is also about invention that makes the world a better place.

GE and wind power

India is now modified to become a superpower; however, nearly 300 million people have no access to electricity because about 25 per cent of the electricity generated is lost to inefficient transmission.

India has a promising solution, which is free and found nearly everywhere — wind energy. According to the Global Wind Energy Council (GWEC), wind energy would provide about 20 per cent of the global electricity demand by 2030. India also believes wind energy — which leads

46

November 2014

all other renewable energy technologies with a share of over 66 per cent — can be the saviour to overcome these challenges.

As India increasingly turns to renewable energy, GE is positioned to provide worldclass wind turbines that are designed, tested and manufactured in India. GE has been evolving in the wind energy business like no other. It has installed more than 18,500 wind turbines around the world.

Talking about GE’s evolution in wind energy, Mariasundaram Antony, General Manager - India Engineering Operations, GE Power & Water, says, “It has been more about investing in technology and looking at the customer’s needs.

The whole strategy is around what kind of different markets we want to play in and what are the market needs which we need to satisfy and how we put the right kinds of technological investments to satisfy the customers’ need.”

Electrical & Power Review

wind power Need-based innovation GE innovates things that matter. “I find out what the world needs,” Thomas Edison once said “then I proceed to invent it.” GE still follows its founder’s philosophy.

In India, GE works towards developing advanced technology solutions that improve the quality of life. In April, GE has lunched 1.7-103 wind turbine — first wind turbine engineered specifically for India’s low-wind speed conditions. The launch of the 1.7-103 is another key step in strengthening GE’s deep commitment to India.

A 100-MW wind farm powered by 1.7-103 turbines can generate electricity required to fulfil the needs of 413,000 Indian homes per year.

Game-changing innovation GE believes that 1.7-103 would be a game changer for India’s wind power, which is rapidly increasing its power generation using renewable energy.

Anil Rajanna, Executive - Renewables Engineering, GE Power & Water, GE India Technology Centre, strongly believes this. He explains, “With the current logistics and trends, 1.7-103 is going to be a game changer. We have installed this and are getting great feedback from our customers. They are seeing larger amount of energy pumping into the grids.”

applications. The resulting system enables power producers and the wind turbines themselves to make data-informed decisions and provide short-term predictable power.

Not only as a leading global brand, GE stands out as one of the best innovative companies. The Fast Company special report on the World’s Most Innovative Companies puts GE 19th on the list. GE, however, believes what is innovative today, it may be challenging tomorrow.

The battery software applications run on the existing control platform and the hardware connects to the existing converter, minimising the changes required to accommodate the battery system.

Rajanna explains GE’s plan with 1.7103 in the future. “As you want to make lower and lower wind speeds viable (say 6-6.5 metres per second), you need technologies that can adapt to lower wind speeds. As the logistics and manufacturing capabilities are opening up, we need to build such technologies that can suit this infrastructure.”

Smart innovation In wind energy, the biggest challenge can be experienced when peak output does not match peak load. Intermittent supply can lead to frequent energy curtailments, which reduces energy production and extends to return on investment.

GE’s Brilliant Battery Applications are a smart solution. Integrating a GE Durathon battery into the wind turbine gives wind farm operators the benefit of energy storage without the high costs of farmlevel battery storage installation. This revolutionary configuration integrates battery technology with three software

Nucleus of innovation The latest 1.7-103 wind turbine is researched, designed, developed and engineered at the John F. Welch Technology Centre (JFWTC), GE’s first and largest integrated, multidisciplinary research and development centre outside the US. GE has issued 100th patent from JFWTC in 2007, and by 2013 GE had filed more than 2,000 patents based on work done by technologists at JFWTC. While talking about JFWTC’s importance, Mariasundaram says, “It is an evolution of the organisation because India is a place of talented engineers. It is also a question of revolution, and people have a sense of curiosity. Here we are a global technology centre. Here whatever we do is feeding the global requirements, including what India needs.”

No wonder GE is successfully moving towards more complex terrains where the physics or the phenomenon is poorly understood.

artsila has become a power giant with its flexible engine solutions that can balance the rigidity of the low-tariff-driven coal plants, promoting renewable energy and lowering the overall power cost of the system. In a conversation with EPR, Nandkumar Pai shares how Wartsila made it possible its journey to the top.

November 2014

Starting with the first internal combustion engine delivered in 1983 to meet the captive power requirement of a cement plant, Wartsila has supplied over 250 power plants in India, totalling to over 3,500 MW. The users include large process industries — including cement plants, chlor-alkali plants, chemical and metal-producing plants, textile units, and glass manufacturing plants — that have benefited from the advantages of reliability and better economics. These plants — running on oil or natural gas — have been also supplied to utility companies to support the grid operations, both for base load as well as peaking applications. Wartsila’s business model has continuously evolved from equipment supplier to a total EPC business model. The company is taking responsibility of operation and maintenance of power plants as well as contributing to shape India’s power sector in making it 24/7 at an affordable price.

Game-changing Wartsila product Wartsila is more into power solutions and its flexible engine solutions can balance the rigidity of the low-tariffdriven coal plants and the infirmness of the greener renewable energy, thereby lowering the overall power cost of the system. Considering the variability of the daily demand curve, infirmness of renewable energy and the falling contribution of the flexible hydro power make coal-based power plants susceptible to cycling.

The internal combustion engine technology acts as a balancer through its technological characteristics such as quick start (0-100 per cent loading in 5 min) and high electrical efficiency (48-50 per cent) across the load range. O&M expenses are insensitive to number of starts and stops, efficiently integrating the various power-generating technologies. This is called as “smart power generation.’

This concept has been quite popular across the globe and is also picking up in India.

Expected technical innovations SPG concept and its implementation in India can be categorised as a breakthrough innovation. In the SPG concept, considering the present and expected generation mix, about 15-20 per cent of the new coal capacity can be replaced with gas- and LNG-based

Electrical & Power Review

flexible power capacity through internal combustion engine technology.

Moreover, such plants are modular and pre-engineered and can be installed in a short time frame, e.g. a 300-MW plant can be installed in 15-18 months. In view of these benefits, SPG is a strong enabler for making India 24/7 at an affordable price.

The recent acquisition of Hamworthy has also given Wartsila access to liquefaction and regasification technology, opening a big opportunity in both the upstream as well as downstream segments of the gas value chain. In the Indian context, Wartsila has strong focus in mid-sized RLNG terminals for both power as well as process requirements.

Competition: a value addition Wartsila respect the competition as it only keeps it always enthused and excited for continuous value creation. This only helps the company in improving the quality of its solutions benefiting the customers. Wartsila has a great team who proactively tries to understand the market requirement and comes out with varied solutions for different customers. Its vision is to create a big market which is self-sustained, based on the continuous value it can bring to country, where all the major players can have a fair play.

Trends to keep industry moving India’s appetite for power is huge which can be seen in the disparity between our per capita power consumption of over 900 kWh whereas the global average of close to 3,000 kWh. Fuel supply is an issue, and LNG will play a major role in the coming years. The country has a cumulative RLNG capacity of close to 24 MMTPA on ground, and a similar capacity is under planning and execution. Also, substantial investments have been made by the country to import cheaper shale gas.

This fits in well with the country’s vision to make India 24/7, enabling substantial investments in SPG through flexible peaking power plants in the country.

Wartsila in next 5 years The value of SPG has been realised by India which can be seen from the recommendations of Central Electricity Authority, regarding peaking power plants and creation of adequate system reserves which analysed the potential for peaking plants in India.

The market is big enough for all the players with such technology, and Wartsila sees a great potential in the mediumand long-term future.

Recently, SgurrEnergy India has been working on the solar PV projects in Sri Lanka, Oceania and Africa, providing technical expertise to these projects from its Pune office.

Game-changing product

SgurrEnergy

SgurrEnergy’s Galion (2nd generation LiDAR) is a wind-measurement device which has been quite a game-changing product for the company. Galion can measure wind speeds and various intervals for a 4-km arc. LiDAR is a mature remote sensing technology that

50

November 2014

is now successfully being used in wind power applications. Galion is based on pedigree LiDAR technology proven in the atmospheric science industry. Galion operates by emitting a pulsed beam and measuring the doppler shift of the light back scattered by microscopic airborne particulates carried by the wind. This indicates the wind velocity in the line of sight. Combining these measurements in multiple directions gives the ambient wind velocity vector. Galion can capture wind speed, wind direction, flow inclination, turbulence, shear and veer. This particularly is useful for measurements across the entire rotor diameter of a wind turbine at multiple locations including ridges and forestry.

Expected innovations There are quite a few significant technical innovations that SgurrEnergy already has implemented across the Europe, USA, China and South America.

These are a few technical innovations that the company is going to implement in the Indian market.

Wind farm site and resource assessment As technology develops and wind turbines get taller, mast height can no longer reach the full height of turbine blades. As a result, wind farm project are becoming more difficult to reliably assess. However, innovative techniques such as Galion LiDAR, which does not have the same restrictions as met masts, allow full measurement across the turbine span, covering the shortfall created by mast height measurement. A properly wind measurement campaign with Galion LiDAR can reduce the project risk by acquiring direct measurements at multiple points across wind farm site from a multiple deployments, whereas a single Galion deployment with mobility

of the device at multiple locations can reduce wind measurement and modelling uncertainties. In turn, this reduces overall project uncertainties, giving a much stronger P90 value for the same P50 values.

Galion can be deployed for wind farm development and on operational wind farms with the following applications: • Wind farm site prospecting (preevaluation of wind potential before investing in a long-term measurement campaign) • Reliable meteorological measurements for noise impact assessments • Site and resource assessment (wind speed, direction, flow inclination, turbulence, shear, and veer) • Model validation and verification by comparison with direct measurements • Measurements at proposed turbine locations and across entire site • Verification of modelled vertical profile extrapolation (WAsP, CFD) • Micro-sitting • Direct measurement and visualisation of non-linear features • Wind turbine wakes • Flow separation and recirculation at forest edges, slopes and in complex terrain • Wind sector management • Post investment appraisals • Reconciliation of revenues with observed resource • Wind turbine power performance monitoring, assessment, and auditing • Operations and maintenance • Power curve verification

Electrical & Power Review

• Site repowering • Refinancing.

Operational wind farms: wake capture The propagation of wind turbine wakes has been a subject of intense study due to their implications for turbulence, fatigue loading and power production in arrays of turbines, particularly offshore. The Galion allows SgurrEnergy to directly measure and dramatically image wind turbine wakes with previously unattainable degrees of precision and detail. The 2nd generation Galion LiDAR introduces a step change in wake studies.

Operational wind farms: assets Whether repowering a site, refinancing a project, or simply reconciling the available resource, a detailed understanding of the wind-flow features — which influence wind turbine productivity and longevity — is critical.

No other device offers the level of detail and accuracy across the entire wind farm site. Galion enables characterisation of wind turbine inflow to drive down project uncertainty and inform: • Post investment appraisal and due diligence • Effective O&M strategies delivering focused investigation, inspection and intervention to optimise asset productivity • Power performance assessment (power curve test) that fully captures inflow across the whole rotor • Performance monitoring, assessment, optimisation and auditing • Wind sector management to

minimise the effects of wake induced turbulence • Yaw angle misalignment correction.

Stands out from the rest There is a stiff competition in the industry where few of the international consultants and Indian consultancy companies offering the same services what SgurrEnergy is providing.

SgurrEnergy stands out from the rest of the group by offering impartial technical advisory as well as engineering services.

The company showcases the technical capabilities to carry out renewable energy assignments, delivering quality advisory services and adding value to renewable energy projects.

Trends to keep industry moving A lot of new technology and trends are being introduced whether it is with wind measurements, energy yield analysis and identifying the underperformance of the current wind farms. However, a company needs to make the developers, lenders and financial institutions aware of this technologies and what value addition it can bring to their projects and investments. SgurrEnergy is constantly involved in technical discussions with the developers and financial institutions to keep them updated with the latest technology and trends.

SgurrEnergy in next 5 years SgurrEnergy has already started expanding the Indian operations and been doing projects in India, Sri Lanka, and Oceania. The company would like to expand the Indian operations, catering to the projects in neighbouring countries, Africa and MENA region.

As India invests on modernising its infrastructures, improving the standard of living, the level of services and connectivity for its citizens, we expect the growth to drive the overall demand for electric powered devices, creating a huge and attractive market for home grown electronics industry. These are opportunities for PMM. As a market leader in power semiconductor for the past 9 years, with strong expertise in RF, and profound system understanding, we believe we are the partner of choice.

Some examples of applications include

LED drivers in lighting for higher efficiency and durability, microinverters in solar systems for lower system maintenance cost, power supply management in telecom equipment requiring less cooling, and RF Power for cellular infrastructures.

In the past 12 years what kind of growth you have witnessed?

We started operations in June 1997 and since then have built a strong team. Over the past few years we have increased our PMM resources in India. We see India as a significant growth region where we have set up branch offices in Delhi, Pune and Chennai extending our reach from main office in Bengaluru.

Which is the most significant vertical for you?

All the verticals are important to us.

Energy efficiency, mobility and security are the three major challenges of urbanisation and mega-cities.

semiconductor our products run in our DNA. We focus on application centric innovation.

What are some of your long- and short-term objectives?

We have a long standing relationship with our customers. They look for increased innovation capability, forward integration, faster development / timeto-market, lower system costs, higher efficiency and simplified systems. We are looking at building a strong technical support team to aid our innovation practices and to help our customers make competitive products.

Are you doing any kind of R&D especially for the Indian market?

We have a system engineering group in addition to sales and marketing. Apart from promoting our products, we are coming up with reference solutions for products. These reference designs which are almost ready-to-use help customers to visualize. Furthermore, we have around 320 people at our design centre in Bengaluru doing a host of design activities for Infineon worldwide.

In future, it is a distinct possibility to localised products for the India as the market segment matures.

Since the semiconductor industry is having huge potential in India,

are you looking at making India Infineon’s manufacturing hub in this sector?

We do not have any concrete plans at the moment but we are following closely the development in this area.

Any new product you decide to launch for the India market?

We identify products which could be relevant for the market at a particular point of time and we promote these products in the market. In a way our marketing efforts are customized.

We have a broad product portfolio that can already serve many different requirements. For example, we are promoting our C7 CoolMOS C7 which provides the world’s lowest RDS(on) per package. Compared to the nearest competitor, the C7 provides 34 per cent lower RDS(on) in TO-247 package and 29 per cent in TO-220. Thanks to its low switching losses, efficiency improvements over the full load range can be attained. The fast switching performance of C7 now enables customers for the first time to operate at switching frequencies greater than 100 kHz whilst achieving Titanium levels of efficiency in Server PFC stages.

This enables higher power density by reducing the space requirements for the passive components. In other words,

same losses at higher frequency lead to size reduction of magnetic components for improved power density. Within SMPS applications, high efficiency targets are required across the entire load range starting at 20 per cent or even at 10 per cent load. With Infineon’s CoolMOS C7, a 650V, this target can be reached easily.

Recently the government announced 100 smart cities projects. How do you think Infineon fits in this context?

The Smart Cities project created a lot of excitement among system solution providers in the ICT domain and this has also a positive effect on semiconductor companies that serve ICT. From Infineon standpoint, we believe the first steps to becoming a smart city is infrastructure upgrade such as high speed digital connectivity, smart power grid, a well networked public transportation system, smart factories and eGovernment services built with long-term sustainability in mind, to cut congestion and pollution.

Infineon has many enabling solutions to support the development of a smart and sustainable city. We look forward to more announcements to see where we can contribute.

solar Trends to keep industry moving One has to look at the solar industry from the perspective of overall electricity or energy industry. The energy cost is going to rise significantly, and solar energy will be competing in this context. A recent example is the cancellation of the coal blocks allocation. This means there will be two metrics of power: one will be the power delivered to one’s home (LCOP, i.e. levelised cost of power) and the other the cost of electricity generated. The LCOP solar will be competing with the grid power, and solar power will be better than grid power. The major trend in power will be the cost of solar power which is going to come down. In terms of generation, it is also getting closer and closer to imported coal. Overall adaptation of solar power will have significant growth, especially in India. With the new government recognising this, there seems to be good opportunities. The market is going to improve in the next 5 years as compared to what it is currently.

Tata Power Solar in next 5 years Tata Power Solar wants to be the leading manufacturing company and EPC solutions provider in India. Currently, the company is leading and continues to lead. Tata Power Solar will continue to make investments in technology to maintain the leadership and has a major share in the market.

wind power

India plans first offshore wind power project renewable energy is the way to go.

It dovetails world’s concerns about climate change and clearly enhances India’s energy security. Considering the country’s 7,600-km long coastal line, Goyal stated that opportunities for scaling up are humongous. The minister also suggested for building partnership with defence, coast guard and shipping to ensure seamless and time-bound approval process.

The joint venture will undertake detailed feasibility study based on the inputs received from pre-feasibility studies and necessary steps for implementation of the first offshore demonstration wind power project.

A

MoU for setting up a joint venture towards undertaking the first demonstration offshore wind power project in the country along the Gujarat coast has been signed by the Ministry of New and Renewable Energy (MNRE), National Institute of Wind Energy (NIWE), and Consortium of partners consisting of National Thermal Power Corporation (NTPC), PowerGrid, Indian Renewable Energy Development Agency (IREDA), Power Finance Corporation (PFC), Power Trading Corporation (PTC), and Gujarat Power Corporation Ltd. (GPCL).

Speaking on the occasion, Piyush Goyal, Union Minister of State (I/C); Power, Coal and New & Renewable Energy, Government of India, described it as a great opportunity in the development of renewable energy resources in the country. He pointed out that Prime Minister Narendra Modi’s message in the US was loud and clear that

November 2014

The first planned demonstration offshore wind power project along the Gujarat coast will be of about 100MW capacity. It has been proposed to provide subsidy for setting up of evacuation and transmission infrastructure of the offshore wind power to the main land, including financial support for carrying out studies such as wind resource assessment, environment impact assessment (EIA), oceanographic survey and Bathymetric studies. The ministry would also assist in obtaining clearances involved during the implementation of the project. This being a first demonstration offshore wind project in the country will certainly provide enough learning to move into this sector by taking up similar viable projects in future, enabling India to enter in the elite club of countries with offshore wind power generation.

Wind power development onshore has reached to commercial stage in India and is fastest growing renewable energy option today. India also has

around 7,600 km of coastline which offers great potential for offshore wind power development. Having more than 22 GW installed onshore wind power capacity, the ministry has taken initiative towards offshore wind power development which includes announcement of Draft National Offshore Wind Energy Policy and preparation of Draft Cabinet note on National Offshore Wind Energy Policy which has been circulated for interministerial comments. Finalisation of the proposed National Offshore Wind Energy Policy will provide a conducive environment for harnessing offshore wind energy, including setting up of a demonstration offshore wind power project to showcase technology and build investors’ confidence.

In early 90s, the ministry had taken up onshore demonstration projects in various states. Total 71 MW of demonstration projects in seven states have leveraged a wind power capacity of around 22,000 MW with private sector investment. Therefore, the ministry decided to go for a demonstration offshore wind power project to showcase the possibility and viability of offshore wind power in the country.

Some sites were identified along with Gujarat and Tamil Nadu coast which have good wind power potential for development of offshore projects. Since GPCL has shown interest, it was decided to plan the first offshore wind power project along the coast of Gujarat.

However, global offshore wind power projects aggregates to about 7.5-GW capacity (UK - 4.2 GW; Denmark - 1.2 GW; Belgium – 0.7 GW; Germany – 0.6 GW; China – 0.4 GW; the Netherlands – 0.2 GW and Sweden – 0.2 GW).

Kwality Photonics started in 1987 as a manufacturer of through-hole LEDs (vertical LEDs). In 1993 the company has started second unit to manufacture digital segment displays. Since 2003, Kwality added capabilities to produce white LEDs. Kwality Group has been in the lighting industry for more than 48 years, producing automotive, railway signalling, electronic indication and specialised bulbs, filaments, tungsten and molybdenum wires. When LEDs emerged as a threat, Kwality Photonics could successfully develop and acquire technology to produce LEDs. Being one of the pioneers in Indian semiconductor packaging sector, Kwality attracted quick recognition from institutions, customers and society which manifested as being the first CACT (Centres for Applied Competitive Technologies) approved LEDs in telecom sector.

Game-changing Kwality product Medium power LEDs proved to be game changers for Kwality Photonics.

Post 2000, LED backlighting industry was the growth engine for LEDs. It resulted in huge capacities in the low power SMD packages. Then innovation pushed the lead frames to evolve into medium power packages by designing

a thermal pad right under the chip, using higher thermal conductive alloys. These arrangements were just right for the high-speed production bonders, resulting in huge drop in unit manufacturing costs.

Kwality was quick to spot this opportunity and introduced medium power LEDs 5630 150 ma and 2835 60 ma LEDs. Then the company got better in the price control. Today it is one of the leaders in the medium power LEDs in 60-150 ma range. The volumes saw huge jump and proved game changer product for the company.

Expected technical innovations Its R&D team is working to develop LED bulbs for niche applications by leveraging its unique die bond and COB experience. India’s first replaceable LED automotive bulb for tail and indicator application is its first product in this direction.

The company is now waiting the mass production. It is also pushing the lumens per package to higher levels to maximise the lumens per given rupee.

Ahead of the competition Kwality Photonics has a firm grip on the increasing performance: efficiency and cost reduction. These two outlooks keep the company firmly ahead of the competition.Trends to keep industry moving The trends that will keep the lighting industry moving forward are standardisation of LED modules for interchange ability and simplification of bulb assembly process, and high-speed conducive raw material processes and materials.Kwality Photonics in next 5 years.

In an exclusive interview with EPR, Shiv Kaushik talks about being a smart power player, making smart solutions and promising smart future.

server software licenses, onsite software installation services and an annual software maintenance contract. Cyan’s CyLec 865MHz RF modules will be installed inside 5,000 new L&T smart meters and deployed by Tata Power in Mumbai. The initial contract with Tata Power for the deployment of 5,000 consumer meters is currently planned to go live in early 2015.

Cyan over the years

In September 2014, a consortium using Cyan’s CyLec smart metering technology was chosen for a smart grid pilot scheme

by Uttar Gujarat Vij Co in Naroda and Deesa districts (Gujarat). The consortium with Cyan is believed to be the only one to have demonstrated an interoperable, sub-GHz smart metering solution as part of the competitive tender process for the pilot.

Cyan has been investing in India for 6 years and has established itself as an industry leader in the smart grid market. Cyan has recruited a commercial and technical India-based team and developed smart metering solutions, branded CyLec, optimised for the Indian market. Year 2014 has been significant for Cyan with the announcement of two commercial deployments in India: a new pilot with state-owned utility UGVCL and further expansion of its partner ecosystem.

In June, Essel Utilities selected a consortium led by Aquameas Instrument Pvt. Ltd. for the first deployment of Cyan’s CyLec Retrofit Advanced Metering Infrastructure (AMI) solution in India.

As part of the contract, 5,000 retrofit modules containing Cyan’s CyLec 865MHz RF modules are being supplied, along with the additional hardware and software required, for a full AMI deployment at Essel. The 5,000 retrofit modules are expected to be fitted to existing consumer meters in Muzaffarpur (Bihar) during the first half of 2015.

Shortly after that, Tata Power selected a consortium led by Larsen & Toubro (L&T), of which Cyan is a member, to provide an integrated AMI solution, consisting of CyLec 865MHz RF modules, data concentrator units, head end

In addition, Cyan has recently signed MoU with Ecolibrium Energy Pvt. Ltd. and Innologix Consulting Pvt. Ltd., respectively to jointly develop, market and deploy integrated smart metering solutions in India.

Game-changing Cyan product Cyan delivers industry-leading solutions developed specifically for the Indian environments. In addition, Cyan recognises that customers need to have a choice of solutions, for hardware and software, to ensure they can achieve cost efficiencies and benefit from technology advances. Cyan’s open communication platform, CyLec, delivers flexibility and innovative functionality to customers.

CyLec is a standards-based, integrated or retrofit smart metering solution.

The integrated solution allows utilities to incorporate CyLec with new and replacement meter installations, and Cyan’s retrofit technology provides

Electrical & Power Review

smart meter smart metering functionality to existing static meters. Using CyLec, utilities can rapidly migrate from basic automated meter reading (AMR), using handheld meter readers, to an automated, twoway advanced metering infrastructure connecting the consumer and the smart grid.

TheCyLec retrofit solution module is the ideal solution for any utility that wants to rollout a smart metering program into its installed base quickly and costeffectively, without having to ‘rip and replace’ meters.

Expected technical innovations Cyan is working with utilities, system integrators and meter manufacturers to provide enterprise level solutions that enable the measurement and control of energy consumption. CyLec solutions are dedicated to electricity metering and optimised for range, data communications, interoperability and security. With retrofit modules to give static meters ‘smart’ functionality, and upgrade paths through AMR to AMI, Cyan’s technology supports utilities as their networks and systems improve and expand.

In addition, Cyan is pioneering the adaption of open standard-based, integrated smart metering solutions in India. As the market progresses to fullscale deployments, Cyan is positioned to support open standards for both meter and communication protocols,

which Cyan feels is integral to the overall success of smart metering in India.

Competition against innovation Adoption of smart metering technology is in its infancy in India and, as an industry leader, Cyan is well positioned as momentum in this market builds. It believes that competition is good for continued innovation in its industry and for customers. However, Cyan remains confident of sustaining its leadership position on the back of its technological superiority, its R&D capabilities, and its continuous efforts to develop and market solutions that meet its customers’ evolving needs. Going forward, Cyan will continue to provide its award-winning smart metering solutions to support utilities as they move towards a smarter grid.

Trends to keep industry moving Cyan believes that a strong, ongoing momentum for smart cities, whether new or upgraded, augurs really well for power distribution modernisation and rapid smart metering adoption in India.

The electricity demand in India is growing at 6 per cent on average annually, and there is an urgent requirement for utilities to reduce transmission and distribution losses, which are estimated to have crossed ` 3 lakh crore. Smart grid technologies have been identified as a solution that could address these losses effectively.

The government has already taken some steps in this direction. Today India has 14

running smart metering pilot projects and, as the results from these pilots are assessed, Cyan expects smart metering adoption to gain momentum across utilities. All these factors are expected to combine to create a favourable environment for greater smart metering adoption in India in the years to come.

Cyan in next 5 years Cyan will continue to be seen as an industry leader, providing “last mile” connectivity for smart metering as a platform to incremental solutions such as electricity meters, gas and water meters, lighting and home appliances.

Its strategy is to build strategic partnerships with system integrators, utilities and meter manufacturers in its target markets. These partnerships with leading companies like Wipro, Larsen & Toubro, Ecolibrium Energy and Innologix will ensure that Cyan always has expert knowledge and connections.

Cyan’s solutions are now manufactured in India at two Tier-1 contract equipment manufacturers.

These facilities are now serving its customers in the Indian market, and Cyan foresees that it will start to export very soon.

Cyan has invested millions of dollars in the Indian market and will continue with its investments in the future. Cyan will continue to grow its team in India with additional sales and business development staff.

ABB to help meet growing power demand ABB, a global leader in power and automation technology, has won an order worth around ` 55 crore from Tamil Nadu Transmission Corporation Ltd (TANTRANSCO), the state-owned utility, to build a new substation in downtown Chennai.

As part of the turnkey contract, ABB will design, supply, install and commission the substation. Key product supplies include nine bays of 230 kV GIS, power

transformers and 23 indoor switchgear units rated at 33 kV. The substations will also be equipped with IEC 61850 based open protection, automation and telecommunication systems as well as ancillary systems.

“ABB India is a proven reliable partner for delivering projects on time. This will be key in establishment of a substation in a congested city centre so as to limit impact on regular life,”

said N Venu, Head Power Systems, ABB India.

The compact substation solution to be deployed in the congested Raja Annamalai Puram area, in the city centre, is designed to blend in with the surroundings, and a quick turnaround time will help to minimise impact to the surrounding areas during construction. The project is scheduled to be completed in 2015.

ince 1998, ICA India has been keeping its promise to “defend and grow markets for copper, based on its superior technical performance and its contribution to a higher quality of life worldwide”. In an exclusive interview, Sanjeev Ranjan shares how ICAI is playing its role in the interest of electrical safety, energy efficiency, and sustainability.

What role does ICAI play in the interest of electrical safety, energy efficiency, and sustainability?

ICAI has evolved since it started its journey in 1998?

In the past 2 years, with the support of Bureau of Indian Standards (BIS), we have initiated to create nationwide awareness on the Revised National Electrical Code of India to enhance electrical safety.

The National Electrical Code contains guidelines, followed by best practices in electrical wiring system, earthing of electrical installation, lightning protection of electrical installation, and electrical safety in residential, commercial and industrial spaces.

ICAI is a member of Copper Alliance and the Indian arm of the International Copper Association Limited (ICA), the leading non-profit organisation for the promotion of copper.

We conduct various programmes with emphasis on electrical safety, energy efficiency and sustainability.

This helps us employ a mix of market development and regulation advocacy approach to encourage the use of copper.

This further helps us accelerate the process and change the long-term markets for copper in a sustainable way through its various major initiatives.

ICA India drives its initiatives through seminars, workshops and training programmes in collaboration with other organisations, institutions and trade bodies. It also publishes technical handbooks, booklets and brochures to spread general awareness of the benefits of copper.

We also receives support from global development organisations to the India programme with major Indian copper producers, fabricators, cable and wire manufacturers, and energy Efficient (EE) motor manufacturers.

November 2014

Our organisation works along with concerned state and central government departments and ministries in guiding policy and regulations to promote the beneficial usage of copper for safety, environment and energy savings.

As a part of the NEC awareness campaign, ICAI and BIS have reached out to over 14 cities, educating about 1,080 key stakeholders, including electrical engineers, designers, electrical consultants and contractors, manufacturing associations, policy makers and technical officers.

The workshops and seminars have a continuous focus on energy-efficient solutions, applicable in various industries such as distribution power quality, distribution transformers, building construction, energy-efficient motors, HVAC (Heating, Ventilating, and Air Conditioning) and renewable energy.

How does ICAI encourage the use of energy-efficient motors or equipment?

We are engaged in creating awareness

Electrical & Power Review

Energy efficiency through different programmes in industrial sectors and also industrial clusters, wherein, we have small and medium enterprises (SMEs).

We started off with eight industrial sectors that are covered under the Energy Conservation Act 2011. In each sector and region, we selected industries which are energy intensive and have energy-savings potential.

With the Perform, Achieve and Trade (PAT) scheme coming into the picture, the focus will be on industrial units which are 478 energy intensive units that have been given a target for specific energy consumption. We target the main industrial sectors so that they adopt energy-efficient technologies to achieve their specific energy consumption target.

What are the new trends that will keep the power industry moving?

Talking about global trends, the new trends are clean energy generation and lesser dependence on fossil fuel, integration of renewable in the grid to manage the variability of power generation, energy storage, and small grid.

In the Indian context, the trend is reduction of T&D losses as well as strengthening the regional power grid network.

Brief about your role in starlabelling programmeme.

The programme was initiated with a strategic aim to work closely with the government agencies such as the Ministry of Power and Bureau of Energy Efficiency (BEE), to ensure implementation of star labelling plan in room air-conditioners (RACs) market in India. Once established, we wanted to improve it further to introduce mandatory Minimum Energy Performance Standards (MEPS).

Initially, the programme covered India but later the activities were extended to other countries like UAE and Saudi Arabia.

Electrical & Power Review

The programme is focused towards regulatory and end-market actions. ICAI has been part of the technical committee of BEE that is responsible for RAC Star Label Plan. Due to continued effort, since the inception of the programme, changes has been achieved in the star labelling first through introduction in 2007 and then it became mandatory from January 2010. Besides, the main focus of the programme was to carry out nation-wise awareness and education programme to drive market transformation of star rating plan by partnering with various stakeholders in the industry. Using presentations and various promotional, educational tools like energy calculators and POS, this initiative has been successful in imparting knowledge pertaining to energy savings in RACs to over 7,500 retailers across India.

What new we can expect from ICAI in the next 5 years?

In the next few years, we are keen on driving sustainable energy. ICAI is working in three areas under this initiative: energy-efficient motors, energy-efficient transformers, and new technology- copper motor rotors.

In the energy efficient motors programme, ICAI with TERI (The Energy Resource Institute) has initiated a project for promoting use of energyefficient motors in various industrial segments, covering small and medium enterprises (SME) in energy-intensive industrial cluster. The objective of the study to estimate the overall energy consumption and saving potential in electric motors in three chemical industry clusters in Gujarat and development and demonstration of identified energy conservation measures, i.e. through high-efficiency motors. The results will be disseminated and implemented in all other industrial clusters.

In the energy-efficient transformers programme, ICAI will be working for implementation of pilots for increasing use of energy efficient and reliable DTs

for Indian power distribution utilities.

In the technology space, the focus is on copper motor rotor programme.

Copper pressure die-casting is a proven technology and thousands of die-cast copper motor rotors are produced annually for motors and pumps applications where energy savings are prime design objectives. Currently, market penetration of copper rotor motors is mainly in low-voltage industrial motors and pumps. Going forward, electric motor with copper rotor will be used in electrical vehicle application.

ICAI initiatives to make copper market sustainable • Encourage safe house wiring practices and use of copper for architecture and decorative use, in the building construction sector • Increase awareness of power quality through Asia Power Quality Initiative Platform • Propagate the use of energy-efficient motors for energy savings in Industries • Promote 5-mm microgroove copper tube heat exchangers technology to OEMs • Promote the use of highenergy efficient motors and copper motor rotors to industries • Reduce distribution losses in the power sector through the use of low-loss distribution transformers • Encourage renewable energy technologies like solar water heaters • Promote antimicrobial copper touch surfaces as the leading material in fighting hospital acquired infections (HAIs).

Modernising energy-efficient lighting

M

ore than five decades back, Eon Electric has showed that the industry doesn’t care tradition; industry cares only innovation. Eon is one of the first companies to start manufacturing CFLs in India. It is also having a powering impact on manufacturing LED lights. In a conversation with EPR, Ved Prakash Mahendru shares how innovation has shaping the lighting industry.

Eon Electric, earlier known as Indo Asian Fusegear Ltd. and started manufacturing electrical products over 50 years back, has always been among the first to adopt, produce and deliver new innovative products. It was among the first to start manufacturing CFLs in India and has again been the first to start the manufacture of variety of outdoor and indoor LED lights including bulbs, tubes, down lighters and street lights. Eon has also developed special LED lights for bringing out the outstanding brilliance of gems and jewellery and brilliant colours of fabrics in commercial display centres.

Game-changing Eon product LED lighting products are indeed a great game changer for Eon. On one hand, they bring the latest, modern lighting technology to all consumers more efficiently and cost effectively than ever before and on the other, they bring greater safety on roads by effectively avoiding dark zones. Above all they substantially reduce electricity bills by 20-90 per cent for the consumers — be they individuals, organisations or municipal corporations. The LED lights have a long life of 50,000 hours, thereby reducing their cost of maintenance. The great electronic base of these LED lights can conveniently incorporate remote-

controlled automatic systems or sensors for creating more colours in life which can also create the wall washers of all homes and buildings inside or outside.

Lighting: the evolution Lighting industry — which came to life starting with the great Edison’s invention of GLS lamp nearly 150 years back — was a major step from the point of changing over wood or oil as fuel for heating to be used as source of lighting too. The original Edison lamp, which converted electric power to heating element, consumed over 95 per cent of the energy to heat and the nominal balance to light.

This great invention and yet highly inefficient GLS bulb has reigned the world of light for nearly 150 years till alternate, more efficient sources of light such as fluorescent lights and CFLs were invented. But this development was a great change from GLS lamp as it quickly started encouraging new thinking, research and development of more efficient lights than the CFLs. Thus, over 10 years back the LED lights came into commercial being. These were extremely expensive and yet more efficient and safe than fluorescent lights and CFLs.

Breakthrough that keeps industry moving This real breakthrough came with the use of LED chip which was instantly recognised as hundred times more energy efficient than GLS lamps and 50 per cent more energy efficient than the fluorescent bulbs and tubes.

The high cost of LED bulbs still remained a great deterrent thus delaying its popularity. The shortage of power is looming large on the society

lighting fluorescent lights, prompting faster growth of LED industry by almost 40 per cent year on year. The seachange in the development of LED lights were natural because LED lights are far more efficient, safe in production, use and disposal unlike CFLs which contain the hazardous mercury.

for promoting industry and lifestyle changes. On one hand, these changes needed more electric power and on the other, power needed to be conserved from its traditional use such as lighting.

Hence the development of LED bulbs received a big thrust and boost.

Fortunately, LED lights have a variety of outstanding additional benefits and characteristics compared to CFLs or

LED lights being electronics based have outstanding benefits of building up automation through light sensors and motion sensors. As a result, they can be put “on” automatically in the evening and “off” in the morning. The LED street lights can have unique ability to sense the density of the traffic on the road and modulate the intensity of the street light in accordance with the traffic on the road accordingly, which ensure safety of traffic on the road and yet ensuring consistent additional power saving throughout the night.

Expected technical innovations Eon is constantly working on making LED bulbs, tubes and other lighting

sources more energy efficient by constantly updating its technology and use of more efficient LEDs. Previously LEDs were considered to provide 7080 lumens per watt but now they can provide 200 lumens per watt. EON is confident that its lights will provide 200 lumens per watt. Obviously, for brilliant lights, people will use 1/10th of the electric power that they currently consume.

Eaton in next 5 years For Eon Electric, the next 5 years are indeed great with the obvious developments of highly efficient sources of light. With the new developments of LED lights, huge mansions will all be brilliantly lit with electric power. A great future we all look forward to.

Eon believes that within the next 5 years, its business of LED lights and other allied products including lithium ion batteries will grow manifold, as the company has the potential to grow the top line to ` 2,000 crore.

Fuelling importance of biodiesel

M

y Eco Energy has been making a lot of news with Indizel, a biodiesel made from multi feedstock and offers a perfect solution with respect to sustainability and availability of fuel.

In a conversation with EPR, Santosh Verma shares why Indizel can be the best alternative of fossil fuels.

My Eco Energy over the time

“Indizel is made of waste and residues of oil, acts as the best viable option and therefore has the potential of becoming a game changer,” states Santosh Verma, Director, My Eco Energy

nd

My Eco Energy has already been creating a lot of buzz within the industry and among the consumers with its first fuel station in Lonikand, Pune. The company is about to open another fuel station in Khalapur along with the old Mumbai-Pune highway.

Indizel as a game changer India is the fourth largest importer as well as consumer of crude oil out of which diesel accounts for 44 per cent. Therefore, India’s economy is extremely energy intensive and relies on coal as its primary source of energy.

As pollution from coal and other fossil fuels has increased to hazardous levels, India is seeking alternatives.

In the present circumstances, biofuel acts as a great alternative but there are issues of sustainability and availability hovering around because most of the biofuel companies operating in India are dependent on one feedstock for the production of their biodiesel. Indizel

by My Eco Energy is made from multi feedstock and therefore offers a perfect solution with respect to sustainability and availability of fuel. Indizel is made of waste and residues of oil, acts as a viable option and therefore has the potential of becoming a game changer.

Expected technical innovations My Eco Energy manufactures fuel by transesterification process which

80

November 2014

is the most commonly used for manufacturing of biodiesel. In the near future, the company is looking at hydro-treatment of vegetable oil (HVO).

It claims that the Indizel produced by HVO process would be at par or even better than the normal diesel. In general, running 100 per cent HVO in an engine with standard settings will simultaneously reduce emissions of nitrogenoxides (NOx) and particulates (PM) compared to regular diesel fuel, withnegligible effects on fuel efficiency.

Striving at bettering Biofuels have potential to solve issues as greenhouse effects, carbon sequestration, growing world energy demand, insecurity of long-term supply and the consequences of fossil fuel. Production of biofuels will help developing countries by reducing imports and improving agricultural economy and subsequently poverty reduction. The world biofuel market has been growing at an accelerated pace in the past 20 years, and this trend is expected to continue in the future due to increasing number of countries participating in it for environmental and security reasons. Biofuels have the potential to meet more than a quarter of world demand for transportation fuels by 2050. Even in India, we have a biofuel policy which has indicative target of 20 per cent blending of biofuels, both for bio-diesel and bioethanol by 2017. So there is a social awareness and therefore usage of biofuels as an alternative to petroleum based fuels will only increase in the near future.

My Eco Energy in next 5 years My Eco Energy aims to be the No 1 supplier of biofuel in India as well as aims at sustainable growth.

Waste heat recovery in India ACC and its exploration the possibility of installing waste heat recovery systems at its cement plants

W

aste heat recovery plants offer a reliable supplement to captive power generation in an energy-intensive industry like cement, particularly in an energy-deficient country such as India. ACC Ltd., part of the Holcim Group, recently launched its first waste heat recovery (WHR) system at the Gagal cement plant in Himachal Pradesh. The WHR system harnesses waste heat discharged in the cement manufacturing process as exhaust gases, channelling them into a boiler that runs a steam turbine and converts it into useful electrical energy. The new WHR project generates electricity at a cost that is significantly lower than that of a captive power plant and only a fraction of the cost of grid power. ACC sees the project as an important step in energy conservation and is exploring the possibility of installing similar systems at a few of its other cement plants.

86

November 2014

ACC Gagal ACC’s Gagal cement plant is located in the picturesque mountainous state of Himachal Pradesh. Commissioned in 1985, it is the major cement plant in the state, with two production lines: Gagal I and Gagal II – representing a total cement capacity of about 4.4 million tonnes a year. Gagal utilises power from the state’s grid and from a standby captive DG power plant. The plant pursues a wide ranging agenda that aspires to achieve high standards of sustainable development in all aspects of its operations – beginning with meticulous hill mining techniques and extending to efficient manufacturing, sound environment management, afforestation and tree plantation, wastewater treatment, as well as an array of community development and social volunteering activities. Most of the Gagal’s manufactured cement comprises flyash-based Portland pozzolana cement, which reduces

carbon emissions. Gagal also promotes the use of alternative fuels and raw materials.

WHR at ACC Gagal A few months ago, ACC Ltd. launched its first WHR system at the Gagal cement plant. This marks an important step in energy conservation for the company as it is the company’s first WHR plant and also the first such project in Himachal Pradesh to deploy WHR technology.

To put it briefly, a WHR system harnesses waste heat discharged in the manufacturing process as exhaust gases, channelling these gases into a waste heat boiler that runs a steam turbine and converts it into useful electrical energy. The newly commissioned WHR unit, set up at a cost of about $16 million, can generate about 7.5 MW of electricity. This supplements the output of Gagal’s captive power plant.

Nantong Wanda supplied the boilers for the project, while Qingdao Jieneng and

Electrical & Power Review

GUEST COLUMN Shangdong Jinan supplied the turbine and generator.

WHR energy at Gagal has proved to be remarkable in several ways — the first of which is that it requires no additional fuel. The cost of generating such energy has turned out to be significantly lower than that of the captive power plant and only a fraction of the cost of purchasing grid power.

Heat recovery generation

for

power

The cement manufacturing process is energy intensive, requiring very high temperatures in the order of 1,400 C in the kilns. Thermal energy is also used in other stages of the process, including the pre-heater, during grinding in the coal mill and raw mill and for drying additives such as flyash and slag.

Significant amounts of heat energy are released as exhaust streams in different stages of the cement manufacturing process, chiefly from the kiln exhaust streams, clinker cooler, kiln pre-heater and pre-calciner. The manufacturing process in Gagal releases about 1,000 Tph of waste hot flue gases at temperatures well above 300 C that are exhausted into the environment.

Waste kiln gases exit at about 260 400 C depending on the number of preheater stages in the plant. The cooler generates hot air of about 200 - 300 C and 80 - 130 kcal/kg. Some of the hot air is used as combustion air in kiln furnaces and elsewhere, the rest of the hot gases are expelled as exhaust into the atmosphere. All these waste gases contain useful energy that can be gainfully exploited. This is the basis of the WHR system deployed at Gagal.

Apart from a cement plant’s capacity, the availability of waste heat is directly influenced by process efficiency parameters and other factors. The number of pre-heater stages in a cement plant has a significant bearing on the overall thermal energy consumption and waste heat recovery potential. The higher the number of stages, the better the thermal energy

Electrical & Power Review

consumption, and hence the lower the WHR potential. Similarly the moisture content in limestone, coal, flyash, slag and other materials used in a plant affects the potential for waste heat recovery as considerable heat would be required to dry raw materials. Again, improvements in plant and machinery efficiencies would offer lower potential for generation of waste heat.

Waste heat to electricity Waste heat generated in cement manufacture has proven to be amenable to conversion into electrical energy, provided it is tapped in adequate measure and the temperature is sufficiently high to make the project viable. In a typical Indian cement plant, the potential generation of power from waste heat is estimated at roughly 20 - 25 kWh/tonne of clinker. The process goes through four basic stages: • Heat tapping and extraction • Heat conversion • Heat dissipation • Electricity feed and control.

Three technologies are recognised as being well developed and effective in the conversion of heat into electricity, using a steam Rankine cycle, an organic Rankine cycle, or the Kalina process. All these technologies involve a pressurised working fluid (water in the case of the steam cycle or an organic compound for the organic Rankine cycle) to be vaporised by the hot exhaust gases channelled through a heat recovery boiler, or heater and then passed into a

turbine that drives a generator.

Steam Rankine cycle This is a thermodynamic cycle that converts heat into work (power in this case). Hot exhaust gases are directed into a waste heat recovery boiler where they exchange heat with the working fluid (water) that is converted into highpressure steam, which then expands in the turbine causing it to rotate and produce electricity. The expanded vapour is condensed into a low pressure liquid in the water-cooled condenser and then is recycled back into the boiler to continue the cycle. The system consists of a suspension pre-heater boiler, air-quenching cooler boiler, steam turbine generator, distributed control system, water-circulation system and dust removal system. This is the most common type of WHR system in cement plants and was chosen for the Gagal plant.

Organic Rankine cycle This process uses organic fluids. Their inherent ability to evaporate at low temperature and yield good levels of condensation allows these fluids to deliver considerable energy during their expansion in the turbine.

Rankine Kalina cycle This is a relatively new concept in heat recovery and power generation, which is a thermodynamic process for converting thermal energy into usable mechanical power. It uses a working fluid mixture, made up of 70 per cent ammonia with

November 2014

87

GUEST COLUMN 30 per cent water. This process offers the potential of significant efficiency gains as compared to the conventional Rankine cycle. It is usually more suitable for medium to low gas temperature heat recovery systems.

Sustainability and other issues WHR units score highly in environmental terms and simultaneously offer several advantages. The primary environmental benefit of the WHR power plant is to produce electric power without burning any additional fossil fuel or contributing any additional greenhouse gas (GHG) emissions. These systems play a vital role in energy conservation as they utilise waste heat and do not need any additional fuels to generate electricity.

They help conserve fuels and reduce overall carbon emissions. While they substitute power from an external grid or a captive power plant, there is an additional advantage of reduced fuel consumption and lower CO2 emissions.

As it is based on waste heat, the energy produced is renewable.

The WHR at Gagal is expected to lead directly to a reduction of over 44,000 tonnes per year of CO2 emissions. By a rule of thumb, it can be said that such units can help reduce up to 25 kg of CO2 per tonne of clinker produced.

The investment involved in setting up a WHR plant is reasonable. On average, the cost of a waste heat based power generation plant would fall in the range of $2-2.5 million per MW.

Conclusion As experienced by ACC at Gagal, the cost of electricity generated by WHR units is cheaper than both captive power and power purchased from an external grid. Encouraged by the Gagal WHR project, ACC has plans to set up similar systems at its other major cement plants in the country to enhance energy security.

India’s cement sector already has several working WHR plants and undoubtedly such plants will become a feature in this fast expanding market. Waste heat recovery can comprise an economical and reliable supplement to captive power generation in an energy-intensive industry like cement, particularly in an energy-deficient country like India. In addition, this practice comprises energy conservation and efficiency that helps the cement industry meet its low carbon technology roadmap for the future.

Reduce transformer losses, maximise efficiency

T

ransformer losses are produced by the electrical current flowing in the coils and the magnetic field alternating in the core.

The losses associated with the coils are called the load losses, while the losses produced in the core are called no-load losses.

What are load losses?

Load losses vary according to the loading on the transformer. They include heat losses and eddy currents in the primary and secondary conductors of the transformer.

KN Hemanth Kumar, Chief Manager Energy Efficient Motors & Distribution Transformers, International Copper Association India underlines the causes of transformer losses and the techniques to deal with

Heat losses, or I 2R losses, in the winding materials contribute the largest part of the load losses. They are created by resistance of the conductor to the flow of current or electrons. The electron motion causes the conductor molecules to move and produce friction and heat.

The energy generated by this motion can be calculated using the formula: Watts = (volts) (amperes) or VI. According to Ohm’s law, V=RI, or the voltage drop across a resistor equals the amount of resistance in the resistor, R, multiplied by the current, I, flowing in the resistor. Hence, heat losses equal (I) (RI) or I2R. Transformer designers cannot change I, or the current portion of the I2R losses, which are determined by the load requirements. They can only change the resistance or R part of the I2R by using a material that has a low resistance per cross-sectional area without adding significantly to the cost of the transformer. Most transformer designers have found copper the best conductor considering the weight, size,

90

November 2014

cost and resistance of the conductor.

Designers can also reduce the resistance of the conductor by increasing the cross-sectional area of the conductor.

What are no-load losses?

No-load losses are caused by the magnetising current needed to energise the core of the transformer, and do not vary according to the loading on the transformer. They are constant and occur 24 hours a day, 365 days a year, regardless of the load, hence the term no-load losses. They can be categorised into five components: hysteresis losses in the core laminations, eddy current losses in the core laminations, I2R losses due to no-load current, stray eddy current losses in core clamps, bolts and other core components, and dielectric losses. Hysteresis losses and eddy current losses contribute over 99 per cent of the no-load losses, while stray eddy current, dielectric losses, and I2R losses due to no-load current are small and consequently often neglected. Thinner lamination of the core steel reduces eddy current losses.

The biggest contributor to no-load losses is hysteresis losses. Hysteresis losses come from the molecules in the core laminations resisting being magnetised and demagnetised by the alternating magnetic field. This resistance by the molecules causes friction that result in heat. The Greek word, hysteresis, means “to lag� and refers to the fact that the magnetic flux lags behind the magnetic force. Choice of size and type of core material reduces hysteresis losses.

tech view are important to the purchaser of a transformer who wants to select the most cost-effective transformer for their application. The use of A and B factors is a method followed by most electric utilities and many large industrial customers to capitalise the future value of no-load losses (which relate to the cost to supply system capacity) and load losses (which relate to the cost of incremental energy).

Put another way, A values provide an estimate of the equivalent present cost of future no-load losses, while B values provide an estimate of the equivalent present cost of future load losses. Most utilities regularly update their avoided cost of capacity and energy (typically on an annual basis), and use A and B values when specifying a transformer. Most small end-users typically use life-cycle cost evaluation methods.

When evaluating various transformer designs, the assumed value of transformer losses (A and B values) will contribute to determining the efficiency of transformer to be purchased. Assuming a high value for transformer losses will generally result in purchase of a more efficient unit; assuming a lower value of losses will result in purchase of a less efficient unit.

What value of losses should be assumed?

The total owning cost (TOC) method provides an effective way to evaluate various transformer initial purchase prices and cost of losses. The goal is to choose a transformer that meets specifications and simultaneously has the lowest TOC. The A and B values include the cost of no-load and load losses in the TOC formula: TOC = NLL x A + LL x B + C Where, TOC = capitalised total owning cost NLL = no-load loss in watts A = capitalised cost per rated watt of NLL (A value) LL = load loss in watts at the transformer’s rated load B = capitalised cost per rated watt of LL (B value) C = the initial cost of the transformer including transportation, sales tax, and other costs to prepare it for service.

Electrical & Power Review

What is the A value?

The A value is an estimate of the present value of future capital cost (non-load dependent) items at a given point in time. It can vary over time as utilities reevaluate their costs on a periodic basis.

(In other words, the A value is the answer to the question, what is a watt of no-load loss over the life of the transformer worth to me today?). Even if there is no load, there is capital that is devoted to fixed capacity to generate, transmit and distribute electricity, which contribute to the A value. The loading that may change daily on the transformer does not affect the no-load loss value. It is calculated using the following formula: A = [SC + (EC x 8760)] x 0.001 / [FC] = Cost of no-load loss in $/watt Where, SC = Annual cost of system capacity in $/kW-year (SC is the levelised annual cost of generation, transmission and primary distribution capacity required to supply one watt of load to the distribution transformer coincident with the peak load).

EC = Energy Cost (EC is the levelised annual cost per kWh of fuel, including inflation, escalation, and any other fuel related components of operation or maintenance costs that are proportional to the energy output of the generating units).

8,760 = hours per year FC = Fixed Charge on capital per year (FC is the levelised annual revenue required to carry and repay the transformer investment obligation and pay related taxes, all expressed as a per-unit quantity of the original).

0.001 = conversion from kilowatts to watts.

What is the B value?

Similar to the way the A value is determined, the B value is an estimate of the present value of future variable, or load-dependent, cost items at a given point in time. (In other words, the B value is the answer to the question, what

is a watt of load loss over the life of the transformer worth to me today?). The B value can also change over time as utilities revaluate their costs on a periodic basis, but once determined, it is a constant value for a given transformer purchase.

The cost of load losses, or B value, is calculated using the following formula: B = [(SC x RF) + (EC x 8,760 x LF)] (PL) 2 (0.001) / (FC) = Cost of load loss cost $/ watt Where, RF = Peak loss responsibility factor (RF is the composite responsibility factor that reduces the system capacity requirements for load losses since the peak transformer losses do not necessarily occur at peak time).

LF = Annual loss factor (LF is the ratio of the annual average load loss to the peak value of the load loss in the transformer).

PL = Uniform equivalent annual peak load (PL is the levelised peak load per year over the life of the transformer. Transformer life cycle is defined as the useful life of the asset and is usually assumed to be 30-35 years).

Specifying A and B values For custom-designed transformers, manufacturers optimise the design of the unit to the specified A and B values resulting in a transformer designed to the lowest total owning cost, rather than one designed for cheapest first cost.

In situations where A and B values have not been determined (or the end-user does not utilise or specify them), such as occur in commercial or small industrial applications, the suggested technique to maximise transformer efficiency is to obtain the no-load and full-load loss values of a specific transformer, in watts.

Case Study

DuPont Tedlar based back sheets for higher lifetime of solar panels Aditya Birla Solar collaborated with DuPont India to set up a 20 MW plant near Jodhpur in Rajasthan Challenge The challenge is to provide an optimal solution that would efficiently harness the abundant sunlight and transform it into clean solar energy. The selection of materials with proven performance and long term durability was critical to provide a truly sustainable source of energy.

Solution

Problem Solar energy holds great promise to help India meet its energy challenge. One out of every four people in India does not have access to electricity. In rural villages that are inaccessible to India’s power grid, such as in Rajasthan, villagers depend on kerosene lamps for light. In the process, they expose themselves to health and safety hazards such as toxic fumes and risks of fire.

Because India receives more than 300 days of full sun each year, solar is an ideal source of energy.

If just 5 per cent of the Thar Desert was covered with solar panels, the energy generated would meet the country’s entire energy demand.

November 2014

DuPont India has been committed to continuous innovation, research and development to make solar energy more competitive with other sources of electricity. Consistent with that, DuPont provides a unique perspective into materials science and the capability to deliver integrated solutions.

DuPont solar solutions are designed to improve the power output and are reliable for lifetime and provide return on investment for solar energy systems. DuPont Solamet metallisation pastes have helped to increase the conversion efficiency of solar cells, significantly boosting the power output of solar panels.

DuPont PV encapsulants surround and protect solar cells and panel circuitry. DuPont Tedlar polyvinyl fluoride (PVF) film-based back-sheets have proven critical to protect solar panels, to ensure long term durability for their 25 year expected lifetime, even in harsh environmental conditions.

Aditya Birla Solar collaborated with DuPont India to set up a 20 MW plant near Jodhpur in Rajasthan. By specifying Tedlar-based backsheets from DuPont in the solar panels, the power output and lifetime of the system was optimised along with the good returns on investment.

Benefit The project till date has been a success. With the benefit of proven materials from DuPont, Aditya Birla Solar’s installation at Jodhpur Rajasthan is delivering approximately 33 million kilowatt hours of clean and sustainable solar energy per year, enough to light up almost 3,00,000 rural households in India.

Applied’s fault current limiters can help to create reliable T&D Materials India, “As the global leader in precision materials engineering, we are committed to applying our expertise to drive the technology innovations needed to create high value products.

The SCFCL reflects our commitment to advance energy efficiency and to greatly benefit the Indian power transmission and distribution ecosystem.”

P

ower outages due to sudden power surges—a common challenge plaguing the power sector in India today that can be caused by lightning and downed power lines –might soon be a thing of the past thanks to technology developed and manufactured by Applied Materials, Inc. By implementing this technology that enables N+1 or N-1 redundancy, a more reliable transmission and distribution of power may soon be a reality in India.

This technology is a superconducting fault current limiter (SCFCL) which is designed to help protect the electrical grid from fault currents - or the sudden power surges that can damage expensive equipment and disrupt power transmission. Applied’s SCFCLs have been successfully demonstrated at a number of sites, and most recently, a unit was successfully installed at a major utility in New York State, USA. In a country like India, with its growing economy and increasing demand for power, both public and private utilities may significantly benefit from this technology. For example, Applied’s SCFCL can help these companies improve grid reliability; protect power system

equipment from severe mechanical, magnetic and thermal stresses, and other undesired consequences of fault currents.

Currently, one of the biggest challenge utilities face is in upgrading their systems for higher power capability or adding capacity to mitigate increased fault current levels. With increase in energy demand, and as more sources for power generation (e.g. such as wind and solar power) are being added to an already overburdened system, the fault current levels are likely to increase.

Therefore, the need to mitigate fault currents is more critical than ever.

SCFCLs may help the utilities overcome these problems. The technology employs the characteristic of impedance on demand whereby impedance is introduced when the system needs to reduce fault levels. This feature may enable SCFCLs to avoid increase in active and reactive power loss, voltage drop or voltage instability that may be found in traditional current limiting reactors.

According to Aninda Moitra, President and Managing Director of Applied

Paul Murphy, General Manager of Applied Materials Power Systems Group, explains, “SCFCL is a scalable solution that promotes grid reliability, in addition to lowering operational costs and other overhead. By way of example only, if a fault current limiter were to reduce fault currents by 50 per cent, the overall mechanical and thermal stresses and associated safety hazards to personnel and equipment would be reduced by a factor of 75 per cent. The scalability of this technology is designed to ensure that it is applicable at the lowest levels of distribution (6.6kV) to the highest levels of transmission voltages (> 400kV).

Managing the power sector in India is critical. Today, constraints in the flow of electricity through the existing transmission system drive inefficiencies and costs for upgrades.

Therefore, there is a pressing need to limit transmission constraints or disruptions to the maximum extent possible.”

India has made huge strides over the past decade in improving the power generation capacity. To reach the full potential of making stable, reliable electricity available to everyone, the focus has to shift towards improving transmission network. Applied’s SCFCL technology may help the transmission and distribution sectors to achieve this goal.
