India’s almost 82 per cent of the total electricity generated comes from thermal power sources, and the country has been leaning towards renewable energy sources for its power generation. Earlier this year, India reached an installed renewable energy capacity of 31.7 GW, or over 12 per cent of the total installed power capacity. At the same time, renewable energy creates tremendous job opportunities.

During the past 3 years, the renewable energy sector in India has created over 70,000 jobs.

According to a recent report by Natural Resources Defense Council (NRDC) and the Council on Energy, Environment and Water (CEEW), around 24,000 full-time equivalent (FTE) jobs were created in the solar grid connected projects between 2011 and 2014, and 45,000 people were employed in the wind energy sector during this period.

The report titled “Clean Energy Jobs and Assessing Opportunities to Boost Financing for Clean Energy Projects in India” says that the country’s solar and wind programs have catalysed rapid growth providing much needed energy access, creating employment opportunities. The analysis also finds that deployment of innovative financing solutions is needed in order to scale India’s renewable energy markets and create widespread job creation.

Apart from the execution of wind and solar power projects, Operations and Maintenance (O&M) also provides tremendous employment opportunities. Regarding wind turbine, the O&M includes regular monitoring and analysis of turbine performance, preventive mechanical and electrical checks and maintenance, and replacement or repair of turbines and other components of the wind farm.

It is estimated that more than 843 million will be residing in Indian cities by 2050. India plans 100 new smart cities and has allocated Rs 70.6 billion in Budget 2014-15 to support this mission. “Smart City” programme will also unleash ample of opportunities for renewable energy sector toward “Smart Environment” building thereby creating employment prospects.

GridSense and Cyan will deliver smart grid solutions to support the reduction of Aggregate Technical and Commercial (AT&C) losses in India and other emerging regions. AT&C losses include technical losses in transmission and distribution as well as commercial losses caused by low metering efficiency and theft.

Cyan’s smart metering platform, CyLec Advanced Metering Infrastructure (AMI), provides bidirectional communication between the customers’ meter and the utility, enabling functionality such as meter reading, fault detection and tamper alerts. This enables a utility to accurately monitor the energy consumption at the meter level and take action when an issue is detected.

GridSense has developed a transformer level system, TransformerIQ that maximises intelligence and minimises costs at the power distribution level. TransformerIQ enables energy providers to monitor all potential distribution transformer failure modes and detects early warning signs, including asset deterioration and illegal activities.

Using a combination of the Cyan and GridSense solutions,

utility customers will be able to accurately measure consumption at the district transformer and compare this with that measured by the combined AMI meters in the same area to detect technical problems as well as tampering and theft.

Ad a n i b u y s La n c o ’ s U d u p i p o w e r p l a n t f o r `6 ,0 0 0 c r Adani Power Ltd., the power business arm of Indian business conglomerate Adani Group, announced acquisition of Lanco Infratech’s 1,200-MW Udupi power plant. The deal is valued at more than ` 6,000 crore.

The Lanco Udupi power plant has already signed with Karnataka Government for further expansion of 1,320 MW. The imported coal-based thermal power plant of Lanco in Udupi, which supplies 90 per cent of the power generated to Karnataka and 10 per cent to Punjab, is the first independent power project in the country, based on 100 per cent import coal with a captive jetty of 4 million tonnes per annum and an external coal handling system in the new Mangalore Port Trust. The capacity can be, if required, expanded to handle another 4 million tonnes capacity.

For Lanco Infratech, this transaction will support the company in reducing its debt and will enable Lanco to receive about ` 2,000 crore as cash. Additionally, Adani Power will take Udupi plant’s long-time debt of around ` 4,000 crore.

Re l i a n c e p o w e r s i g n s Mo U t o a c q u i r e h y d r o p o w e r Reliance CleanGen Ltd. (RCL), a 100 per cent subsidiary of Reliance Power Ltd., and Jaiprakash Power Ventures Ltd. (JPVL), a subsidiary of Jaiprakash Associates Ltd. (JAL), has announced the signing of an exclusive Memorandum of Understanding (MoU), for the 100 per cent acquisition by RCL of the entire hydroelectric power portfolio of JPVL’s hydroelectric power portfolio has an aggregate capacity of nearly 1,800 MW, fully in operation, the largest in the private sector in India, and with an asset base of over ` 10,000 crore.

JAL intends to utilise the entire proceeds of the proposed transaction to reduce its outstanding debt, and thereby deleverage its consolidated balance sheet.

The completion of the proposed transaction would make Reliance Power the largest provider of hydroelectric power in the private sector in India.

In addition to the assets contemplated to be acquired under the proposed transaction, Reliance Power has hydroelectric power projects aggregating over 5,000 MW under development, of which 4,200 MW are located in Arunachal Pradesh, 700 MW in Himachal Pradesh, and 400 MW in Uttarakhand.

OPEN FORUM Will the Gujarat model work for India, especially in the power sector?

Ideas should be adapted according to the needs of states The Gujarat model has worked very well for the state. It is a great balance between being business friendly and agriculture friendly. If we talk about the power sector alone, the Gujarat model does not believe in doles and direct subsidies. There are limited subsidies for the rural sector but lower than in other states. Farmers get limited power at just over 60 paise per unit, but they get 24/7 power at higher commercial rates. That’s why Gujarat runs an economically viable power sector. Additionally, there is a separation wherein domestic and agricultural load is segregated. Hence, there is great learning in the Gujarat model whether it is agriculture sector, or business sector or power sector. As India is a land of diversity, the key ideas should be designed and adapted according to the different needs of different states. The learning of the model should be replicated in such a manner that it suits the needs and wishes of all the states, making it viable for the entire nation. — Santosh Verma, Director, My Eco Energy

Irrespective of model, there should be a political will The model which will work best for the Indian power sector is a three-pronged strategy of governance, accountability and time-bound implementation. Instead of getting lost in the stereotype, let every state ensures these three key ingredients of development. This would mean reforming the power sector as a whole, backed by conducive policies and strategies for programme implementation.

Public-private partnerships (PPP) must be encouraged in this sector; term loans should be made more attractive, and custom duties on capital equipment for power infrastructure projects must be rationalise. Even incentives should be made more attractive to encourage import substitution along with after-proper assessment and a reasonable extent of FDI. Strong measures are required to tackle bureaucratic delays in implementing power projects, and the politics of subsidies should give way to tariff rationalisation. Finally, irrespective of the model, there should be a political will to reduce aggregate technical and commercial losses in distribution to manageable levels. — Jayant Sinha, Head (Systems and Power), Enzen Global Solutions

Power Ministry preaches ‘Make in India’

September 2014

he new government is working day and night to have a power sector that is really empowering.

Introducing a new bill, focusing on renewal energy, and imagining a future India with smart cities, the Power Ministry is on its way to transform the talk into walk. In an exclusive interview with Subhajit Roy, Mr Uma Shankar talks about everything from attracting private sector participation to achieving energy independence.

The government is planning to bring a bill, amending the Central Electricity Act, in winter session of Parliament to improve the tariff policy and regulations in the power sector. What we can expect from the bill?

Amendments to Electricity Act 2003 have been under discussion for some time now. The initial discussions centred around making the act stronger in terms of timely tariff revisions by state electricity regulatory commissions, providing them ‘suo motu’ powers to fi tariffs if discoms did not prefer tariff petitions within prescribed timeline, increasing the quantum of penalty for non-compliance of the directions of RLDCs and the central/state commissions, providing a framework for review of functioning of the SERCs, stronger provisions to ensure open access and prevention of the same at the state level, taking the consumers of electricity of 1 MW and more out of the regulatory purview, provisions for separating the business of electricity distribution into distribution system management business (carriage), and electricity supply business (content), among others. I expect that the

proposals for amendments will be along these lines.

There is a concern of lack of private sector participation in the power segment. Even there is believe in India Inc.—“go anywhere, but not to power”. How is the ministry trying to change the perception or to attract more private sector participation?

The issues before the power sector principally concern fuel, lack of demand for power from utilities, inadequate transmission capacity and poor financia condition of discoms. The ministry of power and coal are said to be engaged in finding so ution to the fue issue for projects already commissioned and those which are likely to be commissioned in the next year or so.

There have been reports of reduction in coal being sold through e-auction, which, one would assume, increases availability to the power sector. One has also seen reports of a few more transmission ines identified for bidding route for construction and operation.

The Government of India is also said to be preparing a scheme for providing incentives through grants for improving the sub-transmission system. An important area is financia condition of discoms. opefu y, sufficient attention will also be paid to this important area, although this is entirely in the domain of the state governments.

Piyush Goyal recently said that India can surpass its target of generating 15 per cent of its energy from renewable sources by 2020. What is your roadmap to achieve that?

Electrical & Power Review

EPR PERSONALITY While setting up renewable capacities in itself is quite possible, the issue of evacuating this power and bringing it to areas where there will be enough demand need to be addressed. Majority of renewable potential is in half dozen states as they will not have the demand for so much of power. It has to be necessarily fed into the grid and made available to other consuming areas or load centres.

This will mean construction of green corridors and inno ati e financing so that transmission costs are not prohibitive.

Another important issue to be handled is the demand for power from utilities and their financia capacity to pay for it. f they find it difficu t, because of their poor financia condition, to e en pay for conventional power which costs less than renewable-based power, there is not much hope that they will go for higher cost renewable power. This has already adversely impacted achievement of Renewable Purchase Obligations (RPO) and the rene ab e energy certificates initiati e. ence, the financia

turnaround of discoms is of crucial importance to achieving the target of 15 per cent from renewable sources.

The biggest challenge in power sector is transmission and distribution losses. What measures the ministry has applied to revamp transmission and distribution systems?

AT&C loss reduction can obviously not be done overnight. It requires sustained effort (and much political will to take unpleasant decisions) over a period of time. There many programmes, already under implementation, directly or indirectly addressing this issue.

R-APDRP is one such important programme. It is basically aimed at reducing AT&C losses to 15 per cent in all towns/cities as well as bringing down gradually for the discom as a whole. This programme has been under implementation for some time. The government will do well to speed up the execution of this programme to

quicken the pace of AT&C loss reduction in the country. R-APDRP has some of the ‘smart’ features required in city electric supply to make service delivery better and consumer-friendly.

Then there is the National Electricity Fund (NEF) Scheme, which provides interest subsidy on investments made by discoms in the distribution system, payment of subsidy depends on the reduction brought about in AT&C losses.

Financial Restructuring Plan (FRP), which has been signed by at least four states whose distribution utilities ha e substantia financia osses, a so stipulates reduction in AT&C losses as per an agreed roadmap.

Rigorous monitoring of the implementation of these programmes will pave the way for reduction in AT&C losses.

Substantial part of these losses is actually theft of electricity, either

EPR PERSONALITY through tampering with the meters, or non-payment of bills, or through illegal connection. The states have to develop zero tolerance for theft of electricity and use the provisions available in the Electricity Act to punish the offenders severely and in quick time. That is when the system will improve and losses will begin to come down drastically. Technology will show up places where theft is happening, but it is the governance which will stop it and prevent it from happening. At the heart of AT&C loss, reduction is good governance. This is what will stop theft, put in place the sophisticated technology available today to improve delivery, and prevent leakages and ultimately pa e the ay for an efficient hea thy discom.

produce power equipment. Besides, India welcomed international manufacturers to set up manufacturing facilities in the country. International majors like Alstom, Toshiba, and Mitsubishi have partnered with Indian companies to set up manufacturing facilities. These initiatives have culminated in substantial increase in indigenous capacity to produce boilers and turbines. As a consequence, the scheme for customs duty exemption has also been withdrawn.

Not surprisingly, with so much power equipment manufacturing capacity available indigenously, power generation companies are asked to give preference to these domestic manufacturers. It is not probably that the government does not want foreign manufacturers; it is that the government would want them to be not just exporters of equipment to India but manufacturers of equipment in India.

There is a talk that NTPC should be asked to lay priority to procure equipment from BHEL rather than from suppliers in China and Korea. What is your view on that?

Finally, how optimistic you are on achieving the target of building ‘100 smart city’?

India encouraged imports by providing exemption from customs duty when India did not have enough capacity to manufacture power equipment. Side by side, recognising the need for setting up indigenous capacity to manufacture the same, India ramped up BHEL capacity to

Smart city is a concept which is yet to be fully developed. The government has also stated quite clearly that they are not sure about this, and they are in consultation with stakeholders to understand what constitutes a smart city and what should be the components of it. Again, it may be

noted that smart city is not a fina stage, but an evolving process. Hence, one may not look at it as a target to be achieved in a short time, like the construction of a road or a bridge.

What is important is to see the elements that go into it and the process by which the government seeks to achieve it.

With rapid urbanisation of the country and the projection that every second Indian will be in a town or city by 2050, the importance of improving the services offered by a town or city cannot be overemphasised.

It is in this light that the government’s announcement of 100 smart cities should be viewed. Considering that resources available will at all times be limited, how these resources can be better utilised in order to improve their availability per capita is the challenge.

This is where technological, IT-based applications will come of immense use to city planners and administrators. A smart city is merely an IT-enabled city is a limited view. IT would be a good enabler in proper distribution of resources. It is also likely to make the system and the administration of resources more userfriendly, something that is sorely lacking in our town and cities.

Empowering smart cities India is on the threshold of change.

The government has stepped on the accelerator to take the “Smart India Mission” to a higher level through substantial budgetary provisions, providing the much-needed thrust under the 12th Five-Year Plan.

The bold vision encompasses 100 smart cities, hich specifica y inc udes the original 30 cities envisaged under the NSGM (National Smart Grid Mission).

INDUSTRY ANALYSIS Government support to domestic solar manufacturing will lead to improved energy security, job creation and huge forex savings

Solar manufacturing: imperative for government intervention

S

olar power is a strategic need for the country as solar power can potentially save $ 20 billion in fossil fuel imports annually by 2030 and domestic manufacturing can save $ 42 billion in equipment imports by 2030, reports a white paper on solar manufacturing in India published by Indian Solar Manufacturers Association (ISMA).

It is estimated that about 100 GW of solar capacity shall be established in the country by 2030. It will also create 50,000 direct jobs and more than 125,000 indirect jobs in the next 5 years. The presence of solar manufacturing within the country will also result in better energy security as it would prevent potential supply side disruptions since the country would not be dependent on imports.

The paper, published in collaboration with KPMG, notes that Indian manufacturing policy recognises solar manufacturing to be of strategic importance.

The report highlights the striking similarity of the solar manufacturing industry today with the electronics industry in the past and suggests urgent measures to avoid repeating the same mistakes. The country currently imports over $30 billion of electronic goods annually making it the 4th largest item in India’s import basket contributing to per cent of ndia s trade deficit. his situation could have been prevented, if the electronics industry was supported during the nascent stage. The cost of catch-up today is enormous. Despite efforts to prop up the domestic electronics industry, India has not been able to curtail the massively growing electronics imports. This is because

However, the solar manufacturing industry has been facing challenges due to ack of a e e p aying fie d and various global factors. These have not allowed the industry to develop economies of scale and an end-to-end supply chain.

The paper highlights that given the strategic need for solar power in India, a holistic policy to encourage domestic solar manufacturing is the need of the hour.

September 2014

many critical drivers such as skilled manpower, economies of scale, R&D capability and the entire ecosystem need sustained government support over a period of time.

Ashwani Sehgal, President, ISMA, said, “Indian solar manufacturing is competitive but suffers due to lack of incentives that are provided to solar manufacturers in other nations. About 40 per cent of the India solar producers have shut down with the industry utilisation at just 21 per cent. Countries with ambitious solar energy generation plans such as China, USA and Japan have strongly supported domestic manufacturers through a number of trade and manufacturing incentives to make them even more dominant in the coming years. These measures include loans at reduced interest, credit guarantees, capital subsidies, tax holidays, antidumping measures and preferential domestic procurement amongst others.�

India drops plan to impose antidumping tariffs on solar cells

I

n a major relief to the local solar-power generators, India has decided not to impose antidumping tariffs on solar cells imported from the U.S., China, Taiwan and Malaysia, a senior government officia said on ugust .

Citing imported equipment was being priced below its normal value and was damaging local manufacturers, the Directorate General of Anti-Dumping and Allied Duties recommended the Ministry of Finance to impose antidumping duty.

The recommendation didn’t receive warm welcome from the industry. In a note submitted to the Ministry of Finance by Assocham, it has stated if

Electrical & Power Review

the anti-dumping duty was imposed, the project cost will increase by 18.83 per cent on minimum side, while it may increase by 75 per cent on maximum side.

D.S. Rawat, Secretary General, Assocham, said, “This would also lead to similar cost hikes for the distribution companies, or the government will have to bear this increase in cost of generation of power. This increase in cost of generation of power would ultimately imply increase in the cost of power to the public at large.”

It seems the rejection of a recommendation underscores the emphasis that Prime Minister Narendra Modi has put on the future of solar power in India. The nation had already

launched a programme in 2010 to raise solar-generating capacity to 20,000 megawatts by 2022 —bringing solar to about 5 per cent of its power mix from nearly 1 per cent now.

The industry also welcomes the move to drop the anti-dumping tariff plans.

They said that the state-of-the-art foreign technology and reasonable overseas loans along with the equipment-import deals are crucial to India’s solar plans.

Almost 82 per cent of India’s total electricity generated comes from thermal power sources, and India has been pulling out all the stops to shift its power generation base to renewable energy sources, especially solar.

Solar PV: key ingredient in India’s energy mix

I “We believe that this is a market where the sustainability of demand for solar can be demonstrated in the near to mid-term future,” says Amit Mehta, Director of Business Development, First Solar India

ndia currently has an installed capacity of 2.6 GW to be ramped up to 22 GW by 2020. India also envisages 4,000 MW ultra-mega solar power projects in several locations in the next 3-10 years, along with `1,000-crore target for solar pumps. In a one-on-one conversation with EPR, Mr Mehta shares the importance of creating quality assets for utility scale solar PV.

Current status of generation India is in dire need of investment in rural distribution. This will create opportunities for additional decentralised distributed generation initiatives as the revamped distribution grids can be better leveraged with the local generation options that a modular solution like solar can provide.

The next round of capacity auctions from the central government for 1,500 MW in several stages over the next 6-8 months also reinforce the positive intent of the government to mainstream solar PV as a key ingredient in the energy mix of India.

Plans in renewable energy sector First Solar’s key focus area in India is to create quality assets for utility scale solar PV and address the energy/RPO needs of the utilities. It also focuses to target the open access industrial and commercial power demand.

Furthermore, the company is to partner with local entrepreneurs and develop solutions for segments in the energy access market on a sca e, enab ing in o of structured capital and enhancing affordability of power in those segments.

Its other priority includes creating solutions where the company combines solar PV with other modes of generation and reduces dependence on liquid fuels,

2 4

September 2014

especially in backup (or even primary power) markets.

First Solar has about 400 MW of its technology in operation in India in the utility-scale solar PV segment. It has also announced development of 45 MW AC of utility-scale solar projects in Telangana. In order to create assets, continued investment into development and limited project equity capital are certainly envisaged.

Implementation of RPO mechanism RPO is a good mechanism for progressively increasing the renewable energy in the overall generation mix.

While most states have announced the RPO, the enforcement has left a lot to be desired.

As the renewable energy costs have come do n significant y, the regu ators should not be hesitant to enforce the RPO and the costs will only come down further, as more capacity gets installed and will also be a good initiative to drive achievement of renewable energy goals .

Future outlook First Solar believes that this is a market where the sustainability of demand for solar can be demonstrated in the near to mid-term future. The existing policy and regu atory frame ork is sufficient to create the demand as long as those policies are enforced. The sector needs reliable, consistent enforcement of RPO along with the reforms in the distribution sector. reation of sufficient grid capacity also needs to be accelerated. As these initiatives make their effects visible, the comfort of the investors to create capacity will accelerate.

Power Minister Piyush Goyal recently said that India can surpass its target of generating 15 per cent of its energy from renewable sources by 2020. The government is pulling out all stops to achieve that. en r oshi shares his confidence on the government’s initiatives.

Additionally, the government has initiated a ene ab e nergy ertificate scheme, which is designed to drive investment in low-carbon energy projects.”

According to Mr Mittal, “For our and the industry’s further growth, conducive government policies are the key in this equation. By creating favourable conditions, the sector will continue to grow exponentially. For ensuring this, the government needs to take concrete action against challenges which are impeding IPPs to set up projects.”

Mr Mittal then shares some of the initiatives that the government should impalement like imposing of import duties on solar generation equipment, ensuring

payment security, priority lending status, RPOs and energy evacuation.

Future outlook The country’s current installed solar capacity exceeds 2,600 MW. The power ministry, facing rising power demand and low installed capacity and acute coal shortage, has been relying on solar power.

of the project development. On a broader way, they need an expert technical solution provider for the complete project lifecycle (right from the carrying out wind measurements till commissioning of the WTGs). This ou d definite y mitigate the key risks associated with their projects.”

According to Tata Power, “The introduction and discontinuation of arious fisca incenti es create confusion among the investors. For example, the generation-based incentive (GBI) was announced in 2011 and then discontinued in 2012. In 2013 Annual Budget, it was introduced again. Then accelerated depreciation, originally introduced in 2002, was discontinued in 2012 and then reinforced in 2014.

The Renewable Purchase Obligations (RPO) needs to be enforced that will give further boost to the sector.”

Government’s approach The wind energy sector got much needed boost after the new government restored key ta incenti es ike and accelerated depreciation (AD) in the recent budget.

Mr Mehta opines, “One of the major concerns over the last few years, wherein the industry has been really very low on the development, has been the non-clarity on the incentives from the Government, particularly on the GBI and AD. The need of the hour is that the government needs to come up with a good ind energy po icy and make an significant effort on the grid system as

e as make it capab e of hand ing the recent and future developments of the large wind farms.”

He also adds that government’s recent c arification on the continuation of the AD as well as the increase the cap on the GBI would surely attract more investments.

“The government is also aggressively aiming at increasing the wind energy generation by making an addition of 10,000 MW every year,” describes Tata Power. “The ministry has proposed a joint study on the status of grid availability in six states with maximum wind velocity along with the wind turbine manufacturers. These tax incentives and new policies will help boost the wind energy sector.”

The government is also promoting wind power projects through private in estment by pro iding fisca and promotional incentives such as concessional import duty on certain components of wind electric generators, excise duty exemption to manufacturers. A 10-year tax holiday on income generated from wind power projects is also available. Loans for installing windmills are available from Indian Renewable Energy Development gency and other financia institutions.

Technical support including wind resource assessment is provided by the Centre for Wind Energy Technology (C-WET), Chennai.

Future outlook adhusudan Khemka, hairman, IWTMA, says in an interview that ind turbine makers are capab e to meet proposed higher targets of the government. According to him, the higher volumes will bring down average cost of installations and e en tariff to make ind po er more attractive. India would be able to attract domestic investments in the sector if the government resolves the issues related to wind power evacuation and renewable power purchase obligations of the state utilities.

The Indian wind energy sector witnessed a slowdown in 2013, however, the introduction of conducive policies makes the sector friend ier to ards private participation.

Off-shore wind There is rarely any concrete development in this sector. “We need to start the detailed feasibility studies being carried out,” explains Mr Mehta. t i take another years for ndia to be ready for its first off shore ind farm. As the development of an offshore wind farm is very complex, the government needs to come up with a concrete plan for the development of off-shore wind farms.”

Power players Among the Indian power players, Tata Power has a gross installed capacity of 8,613 MW, out of which green energy sources generate 1,206 MW. The total operating capacity from clean energy source are 461 MW from wind farms, 54 MW in solar generation, 447 of hydro and 240 MW from waste gas based generation. Tata Power is orking to ards achie ing a 0 25 per cent contribution in power generation from ‘clean power sources’, which would include a mix of wind, hydro, solar, geothermal and waste gas generation.

In the current year, Tata Power has set a target of commissioning at least 150 MW of wind farms and 50 MW of solar projects.

SgurrEnergy, a Glasgow-based renewable energy pioneer, offers an impartial, pro-active assessment of any renewable energy project irrespective of the stage of development.

Induction motors are the most commonly used prime mover for various equipment in industrial applications. In induction motors, the induced magnetic fie d of the stator inding induces a current in the rotor. This induced rotor current produces a second magnetic fie d, hich tries to oppose the stator magnetic fie d, and this causes the rotor to rotate.

The three-phase squirrel cage motor is the workhorse of industry; it is rugged and reliable, and is by far the most common motor type used in industry.

These motors drive pumps, blowers and fans, compressors, conveyers and production lines.

DC motors Direct current motors use directunidirectional current. DC motors are used in special applications where high torque starting or where smooth acceleration over a broad speed range is required.

Growth barriers The biggest challenge for India’s electric motors market is the lack of funding from private and public institutions as the power industry depends on credit availability for implementing new projects. The government, however, is said to be preparing a scheme for providing incentives through grants for improving the sub-transmission system.

Even the high price has been a major challenge in the growth of power motors.

Green Zone As the gap in the electricity demandsupply is mounting, the expansion of hydropower is gaining importance Climate change and other negative effects of using fossil fuels for power generation along with growing concerns over energy security are driving the expansion of hydropower around the world. Though reservoir-based hydropower projects have come under criticism due to CO2 and methane emissions beyond acceptable limits, most hydro-rich countries have followed an integrated full life-cycle approach for the assessment of the benefits and impacts to ensure sustainability.

India is endowed with rich hydropower potential to the tune of 148 GW (which would be able to meet a demand of 84 GW at 60 per cent load factor) which makes it one of the most important potential sources to meet the energy security needs of the country.

Installed hydropower generation capacity and share in total generation

P

ropelled by sustained economic growth and rise in income levels, India is poised to face significant increase in energy demand in the next few decades which also translates into higher demand for electricity. Considering an energy elasticity of 0.82, India is projected to require around 7 per cent annual growth in electricity supply to sustain a GDP growth of around 8.5 per cent p.a. over the next few years. This requires tapping all potential sources to address the deficit and meet the demand growth for accelerating economic development while taking into account considerations of long-term sustainability, environmental and social aspects.

The nation has also around 36 GW of installed hydropower capacity whereas an additional 13 GW is under construction.

This puts the total capacity which is yet to be tapped at around 67 per cent of the potential. Countries such as Canada and Brazil had harnessed around 69 and 48 per cent of the economically feasible potential back in 2009.

Recent trends The government of India has increased financial allocation, along with other non-financial supports to prioritise hydropower development and increase capacity addition.

Accordingly, in the 11th Five-Year Plan, the target for hydropower capacity addition was placed at 16.5 GW, which was almost half of the total installed capacity then. However, the achievement, at around 5,400 MW, was well short of the target.

Hydropower planning

From a regional perspective, over 93 per cent of the total potential in the north eastern region is yet to be tapped, primarily in parts of the Brahmaputra river basin.

The scenario is in sharp contrast to the southern and the western regions where more than 65 per cent of the potential has already been harnessed.

The government of India has, over the years, taken a number of initiatives to prioritise hydropower development and to attract investments in the sector. Key measures include the preparation of a shelf of well-investigated projects, which could substantially reduce risk perceptions, streamlining clearance procedures, the provisions of open access and trading as per the Electricity Act 2003, etc. However, issues in implementation of such policy initiatives and regulations still plague the sector resulting in the declining share of hydropower in India’s energy mix since 1966.

Current issues and challenges

Hydropower planning Planning for hydropower development in India has generally been oriented towards individual projects. However, this approach has several limitations for sustainable development of an entire river basin. Inter-state disputes are another aspect which hinders integrated river basin development for hydropower projects. A large number of hydropower projects with common river systems between adjoining states are held up due to a lack of inter-state agreements and disputes on water-sharing. The Sutlej-Beas dispute between Punjab and Haryana and the Mullaperiyar dam conflict between Kerala and Tamil Nadu are well-reported examples of water-sharing disputes between states.

Land acquisition Land availability and acquisition are among the core structural issues that impact almost all infrastructure sectors. Problems arising in the acquisition of land for hydropower projects are causing suspension and delay in construction activities.

September 2014

37

Green Zone Till recently, under the 120-year-old prevailing act, land acquisition for public purpose had been beset by several issues surrounding processes, procedures and compensation, as the term ’public purpose’ was never clearly defined. The new law, which came into effect from January 2014, attempts to address the social inequities in the existing framework of land acquisition.

There are still serious issues which need to be addressed to remove constraints in infrastructure development.

Safeguard issues Construction and operation of hydropower dams can significantly affect natural river systems as well as water and wildlife populations.

Furthermore, hydropower projects involve submergence, causing the displacement of project area people.

The rehabilitation of project affected people is also a major issue which is more pronounced in the case of storage-based hydropower projects, as was evident during the development of the Tehri dam. The project met with mass protests and public outcry on the issue of safety, environment and rehabilitation, resulting in unusual delays (e.g. the Tehri dam was commissioned more than 25 years after R&R was started).

Market development The power market development in India is still at a nascent stage. Though section 63 of the Electricity Act makes competitive bidding mandatory for all power procurement, hydropower projects are exempted under a sunset clause which expires by end 2015 (as per the June 2011 amendment to the Tariff Policy 2006). The deferment for hydro power is based on the recommendation of a Power Ministry taskforce, which cited high risks and uncertainties inherent to these projects as among the reasons why it is difficult for hydro projects to compete with thermal generation on long-term basis.

Financing Hydropower

projects

are

capital-

intensive. Financing them, by finding an optimum balance between bankability and affordability, is often a challenge.

Although the operating cost of projects are minimal and the project life longer than thermal, there are multiple other factors that make hydropower difficult to finance.

Technical challenges Techno economic viability of hydropower projects depends on the geology, topography, hydrology and accessibility of the project site. Even if extensive investigations using state-ofthe-art investigation and construction techniques are adopted, an element of uncertainty remains in the subsurface geology. Geological surprises during actual construction cannot be ruled out. This unpredictable geology is more pronounced in the young fold Himalayas where most of the Indian hydropower potential resides. Such technical challenges add to construction risks.

Enabling infrastructure A number of hydropower projects are located in remote sites in states which do not have adequate demand for electricity. This creates the requirement for developing enabling infrastructure for power evacuation. The ’chicken neck’ presents geographical constraints in developing requisite transmission infrastructure for hydropower evacuation from the north east. There are certain other challenges for the coordinated development of the transmission network, e.g. identifying beneficiaries well in advance, developing excess evacuation capacity keeping in mind the future development of projects.

Furthermore, the plant load factor (PLF) for hydropower projects is typically less than 50 per cent, as a result of which significant transmission capacity is under-utilised. All these result in higher transmission costs.

Hydropower projects also require the development of associated infrastructure such as roads and

bridges in the area. Inclusion of the cost of development of such associated infrastructure increases the cost of power generated affecting project viability and sustainability.

Lack of infrastructure such as schools, hospitals and difficult access to sites often become blocks to moving skilled manpower to difficult project sites.

Governance framework Strengthening of governance in the natural resource sector is a key determinant for sustainable and inclusive growth.

A nation needs to have an overarching policy framework, specific sector strategies, and clear and transparent processes for accelerating hydropower development.

Benefit-sharing framework Mitigation of social and environmental risks also plays a critical role in the development of hydropower projects.

Benefit-sharing is a commitment by the government and the developer to share the monetary and nonmonetary returns with stakeholders.

Facilitating investments and financing In order to attract investments for capital-intensive hydropower projects, it is necessary to address the concerns of developers, consumers as well as PAPs. To broaden investment avenues, the government needs to facilitate optimum risk allocation and often, on a case specific basis, better upside to developers.

Technical capacity development Hydropower development involves significant challenges on account of terrain and geology. The solution to such challenges requires capacitybuilding of the agencies involved as well as the introduction of modern techniques and technologies. The capacity-building initiative will need to appreciate the technical challenges specific to hydropower and equip the concerned institutions with tools, training and systems to help address them.

Technological advances in distribution transformers Electrical energy has been used as a driving force in industrial units and power stations due to its versatility, usability and eco-friendliness. The electrical energy is easily transferred from one voltage level circuit to another voltage level circuit by transformers which are static electrical equipment.

Transformers are robust and sturdy without any moving parts. These also require least maintenance compared to other electrical equipment.

The core losses have two components: eddy current losses and hysteresis losses. The hysteresis losses are directly proportional to frequency and more for non-linear loads.

In order to reduce these both iron losses, new amorphous cores are developed for transformers.

The amorphous core is made from a non-crystal substance created by rapidly freezing liquids of high temperature.

As the eddy current losses are proportional to square of thickness of laminations, the thickness of laminations of amorphous cores will be of the about 0.025 mm which is about 1/10th of laminations of silicon steel. This causes reduction of eddy current losses considerably.

The overall reduction in iron losses (combination of both hysteresis and eddy current losses) in amorphous core transformer will reduced by 1/5th that of iron losses in silicon steel cores. At a flux density of 1.3 tesla, iron loss of amorphous core is about 0.27 W/kg where in silicon steel it is about 0.71 W/kg.

The failure rate of distribution transformers in rural areas is higher compared to urban areas. Wide variation in ambient conditions and loading pattern cause undesirable breathing and ingress of moisture which allow oxygen to come in contact with transformer oil. The moisture weakens the dielectric strength of oil that forms sludge which will restrict the natural circulation of oil inside transformer and also this sludge deposit of winding. Due to restriction in oil circulation cause increase in oil temperature and final winding temperature that may lead to failure of windings.

The CSP transformers consist of mainly three components: • Primary fuse: Internal expulsion fuse for system protection • Secondary circuit breaker: for over-load and secondary fault protection • Surge arrester: for lightning protection.

The CSP system protects the transformer from lightning, secondary faults and severe overloads. The system also provides visual warning of uneconomical loading conditions and protects the distribution system from line “lock-out” during transformer failure. For secondary fault and overload protection, the circuit breaker is mounted inside of the transformer and connected between the secondary winding and the secondary bushings in such a way that the load current and fault current flows through the circuit breaker.

For line “lock-out”, it is connected between the incoming highvoltage lead from the bushing and the high-voltage line.

Primary fuse In a CSP transformer, the primary fuse is mounted inside the transformer and the rating of the fuse is determined on the basis that it should not for surge. As per the British Electricity Authority’s experience, the rating of fuse will be selected for 12 times the full load rated current for 10 ms. This fuse is connected in series with primary winding. This fuse is housed inside of the primary bushing and connected to the highvoltage winding through terminal block.

Secondary circuit breaker In the case of cyclic loads (containing peaks and valleys), where peak load is of relatively shorter, transformers smaller than the peak loads can be safely installed without any rapid loss of transformer’s life due to overload. The CSP circuit breaker will permit the transformer to function within cyclic loads up to the point where the amount and duration of the peak load begins to cause significant loss of transformer life. When this point is approached, the signal light will light with the first indication that the loads on this particular transformer have grown to the point when significant insulation deterioration can occur.

As the mounting of surge arrester closer to the transformer, the shorter will be the ground lead connection Fig. 7: View of CSP between the arrester and the Transformer installed in field. transformer.

If a fault occurs in the windings or some other part of the transformer, it will cause abnormally large currents to flow and the flow of these currents will cause the fuse to melt, open and clear the circuit. When this type of fault exists, the transformer must be removed from service for repair. Any fault ahead of the transformer will not be seen by any of the transformer’s internal protective devices and has to be cleared by other protective devices upstream from the transformer.

Transformers play a major role in power transmission and distribution system because the generator terminal voltage will be less due to constraints in insulation cost, and transmission voltage will be high to curtail T&D loss.

As transformers are in the circuit all the time and iron losses will be continuously occurring, use of amorphous core transformers will reduce the iron losses by about 70 - 75 per cent which helps in reduction of T&D losses considerably.

CSP system protects the transformer from lightning, secondary faults and severe overloads. It also provides visual warning of uneconomical loading conditions and protects the distribution system from line “lock-out” during a transformer failure.

Lemcon China Co. Ltd Shanghai office provided design coordination and supervised SCAD in utilizing Tekla to produce the model, and Tekla Shanghai and Tekla Finland provided software support for Lemcon’s BIM pilot in China.

As the cladding processing period for Kirnu is long, the design and fabrication of the cladding was done at an early phase to ensure that the construction can be finished on time. SAP 2000 software was used for the design calculations.

Both SAP 2000 and Tekla support open API (Application Programming) that enables full roundtrip functionality between the two software applications.

Because of this feature the Tekla model can be easily updated after calculations and vice versa. Detailed design for the construction was finalized with Tekla Structures after the calculations.

Steel fabrication Shanghai Baoye Construction won the bid for the Kirnu project’s steel fabrication and erection in April 2009. All steel parts and assemblies were named, numbered and specified according to the guidelines of design coordination.

Bolt connection information was given to Baoye engineers, and they created connections to the Tekla model.

“Engineers checked out the complex connections by rotating the model and were able to accurately generate all steel shop drawings from the structural model, thus saving in material costs and avoiding waste. The construction management team used the 4D scheduling functions in Tekla Structures to follow up on the steel fabrication process and erection of the building.

BHEL achieves major breakthrough by developing fuel flexible supercritical boilers I ndia’s power generation is mainly coalbased and the power sector is currently plagued by coal shortages where power plants are stranded due to nonavailability of indigenous coal supplies.

This has triggered a series of companies to either resort to operating the plant on part load due to non-availability of domestic coal or make up for the shortfall by blending indigenous coal with imported coal. The performance of power equipment is dependent on the coal being fed to the power plant.

Bharat Heavy Electricals Ltd. (BHEL), a Maharatna PSU, has been designing boilers for the past 30 years and has extensive experience of designing boilers fired with indigenous as well

as imported coals, exhibiting several variations. Based on BHEL’s extensive experience of working with a great variety of indigenous as well as imported coals over the years, BHEL has developed a new boiler with fuel flexibility of indigenous and imported coals. BHEL is now ready to offer the new boiler design to overcome these issues.

This new boiler design is based on a unique combination of indigenous imported coals but capable of firing both extremes of 100 per cent domestic coal as well as 100 per cent imported coal.

It will provide developers with much needed freedom regarding the ratio of blending as well as the characteristics of the domestic and imported coal to

be blended. This enables the boiler to work over the entire range of blending ratios and would protect the project developers against the vagaries in coal availability, thereby providing him with an opportunity to operate the plant throughout the year.

BHEL has a state-of-the-art coal research centre at its Tiruchirappalli plant which will be used to identify the unique combination of blended coal after analysing imported and domestic coal samples supplied by the customers. The associated boiler auxiliaries, also manufactured by BHEL, will be designed to accommodate the variation during firing of different type of fuels.

DEIF’s solar solutions: cost-effective, eco-friendly DEIF Advanced Solar Controller (ASC) enables to share the load between solar PV cell and diesel/gas genset with maximum solar penetration, thus results in maximised savings even during utility failure

S

olar Power – The need of the hour Across the world, the need to make the energy portfolio environment friendly is a pressing need.

Among the renewable sources, solar power is gaining momentum in India with the push given by government and the abundant solar potential in India. The increasing demand is driving down the cost of solar energy which is attracting more and more investment in this sector.

groups is a challenge. This leads to burning the fuel (diesel/ gas) for the genset to take the entire load for the duration for which the utility is absent, in spite of solar power source being available.

DEIF’s answer to the challenge DEIF has come up with an innovative solution to this challenge.

DEIF introduces the Advanced Solar Controller (ASC), a solution that provides integrated solution for systems with utility, diesel and solar power source. The system provides an interface between the diesel/gas genset and solar, with or without presence of utility power - a solution that enables you to share the load between solar PV cell and diesel/gas genset with maximum solar penetration, thus resulting in maximised savings even during utility failure. DEIF solutions being cost-effective balance your economy and conserve the environment as they are highly efficient.

While the investment and increasing of solar share in the energy sources is fully justified, it is also equally important to have efficient controls that will enable solar penetration to maximum possible extent including the possibility of exporting the excess power back to the grid.

Challenge with solar In a contemporary system, solar power can only be utilised as long as the utility supply is available. In the absence of utility, solar power can no longer deliver the power and the diesel generators come in to deliver the backup power. The Solar systems are not geared up to supply power along with the diesel or gas genset as the load sharing between the two

A solar system consists of series of PV cells connected to their respective inverters. DEIF’s solar controller is connected to the master inverter of the group of inverters and interconnected among utility and genset controllers through CAN bus

power brand communication. DEIF’s solar controller serves as an interface between solar source and the diesel genset controllers/utility power, namely Advanced Genset Controllers (AGC), over the CAN bus to adjust power output to meet the load requirement with solar system taking the maximum load share. When the utility fails, genset start up to provide the reference and provide minimum load that will let it run efficiently and let the solar meet the rest of the demand. If the solar power output decreases due to bad sunlight, the deficit will be met by diesel/gas genset through the intelligent interface, thus ensuring reliable supply of power in all conditions. If the export of power from Solar is not demanded then the Advanced Solar Controller will restrict the solar generation to the desired limit.

How much can you save?

On an average, considering power loss of up to 20 hours per week implies that in a year you can have almost 1,000 hours of lack of utility power. Considering that the diesel consumption normally is of 125 litres per hour and assuming 1.5 $/litre as cost of diesel, for 1,000 hours of no utility power, $ 187.5

per hour is the cost for running a diesel genset for one hour.

For 1,000 hours you would spend $ 1,87,500 and for running two gensets, the total spending will be $ 3,75,000 on fuel cost alone. In addition to this, the cost for handling the fuel, managing resources, maintenance of genset, gas emissions, and environmental setbacks add to the overheads.

DEIF’s solar solution enables you to use solar power even in the absence of utility with high solar penetration. For example, with a 60 per cent solar penetration one can run just one genset and save on fuel cost of the other in the period of utility failure which implies a saving of $ 1,87,500. Using solar for the additional period of the year can make that period also further green and help maximise the project’s overall return on investment. DEIF’s solar solution can be a boon to India’s evolving solar sector.
