Editor's Note India accounts for 5GW+ solar energy and 23GW+of installed wind generation. With the target set at 160GW of power generation from solar and wind by 2022 the government is taking all steps to boost the market. Interestingly, the bottleneck for large-scale integration of renewable energy is inherent intermittency of renewable resources. Energy storage can help us to fully incorporate solar and wind power seamlessly in the electricity grid. Several energy storage technologies are currently available in the market today with lead acid batteries accounting for more than 90% of the Indian energy storage market. However, advance technologies like Li-ion, flow batteries and sodium sulphur are also witnessing adoption and market gain. However, one of the barriers for widespread adoption of energy storage technologies is price. Price reduction will play a key role in promoting widespread use and adoption on the grid scale. In addition to price reduction, policy support from the government and incentives like Viability Gap Funding, Accelerated Depreciation etc will go a long way in promoting energy storage adoption in India. The cover story sheds light on this and bring forth the opportunities that makes India an attractive destination for global energy storage players. As always this edition has some great features and updates from the solar and wind industry in India. I hope you enjoy reading this edition and like always we are eagerly waiting for your feedback and letters.

Happy Reading, Santosh K Editor Santosh@supersmartenergy.com

Headwind in the Wind Sector in India

Y16 saw the highest wind energy installation in a year at 3,472 megawatt (Mw), up 50 per cent from the previous year. The last time the wind energy sector witnessed such frenzied activity was in FY12. Notably, Madhya Pradesh attracted the bulk of the wind energy capacity addition in the last financial year - 1,290 Mw, or 37 per cent of the total capacity installed during FY16 - thanks to the state's higher power tariff at Rs 5.96/kilowatthour (kwh). Maharashtra's policy and push for a tariff of Rs 5.81 (for zone-1) resulted in wind energy addition of 1,074 Mw in the state. Rajasthan, Gujarat and Andhra Pradesh also saw more instalment during FY16 compared to the previous year at 688 Mw (20 per cent of total capacity), 386 Mw (11 per cent) and 363 (10 per cent), respectively. After the announcement of withdrawal of Accelerated Benefits in the budget 2016 there is a question mark on the pace of capacity addition in the wind sector after March 2017 when the AD benefits will come to end. This coupled with the reduction in tariffs in Madhya Pradesh, delay

in payments by state-owned utility in Maharashtra and slowdown in signings of fresh PPA in last few months would be impacting fresh wind energy capacity additions in the country. ICRA notes that reduction in preferential tariff by SERC is a negative development for new wind energy projects to be commissioned in MP, as it is likely to result into moderation in project IRR by about 360 basis points assuming PLF level of 22%. This coupled

with slowdown in signing of fresh PPAs over last 6-8 month period & reported delays in payments by state owned utility in the state of Maharashtra (as per Industry sources) is likely to further impact fresh capacity addition expected in the country in near to medium term to some extent. This is given the fact that wind energy capacity addition in State of Maharashtra and MP together accounted for about 35-40% of incremental capacity addition seen on all

IRR (Tariﬀ till FY2016)

India level in last 2 year period, given the fairly attractive feed-in tariffs notified by SERCs in both the states. On the contrary, upward revision in tariff by SERC in state of TN is a positive for new wind energy projects in the state, although tariff determination process has been significantly delayed (with previous tariff order issued in July 2012 as per which tariff validity was till July 2014). As per ICRA’s estimates, project IRR for new projects in TN is expected to improve by about 270 basis points assuming PLF level of 24%. This in turn augurs well for improvement in fresh capacity addition in the state, given the high wind energy potential with attractive PLF level. However, realization of this potential is critically dependent on the extent of improvement in transmission bottleneck in the state as well as payment discipline by state owned Utility. The state of TN is also yet to participate in UDAY (Ujwal Discom Assurance Yojana) scheme as notified by Government of India in November 2015 for financial turnaround of the state owned distribution utilities. From a regulatory perspective, preferential tariff norms by SERCs across the key states (which have wind resource potential) are not consistent with the guiding principles/norms as stipulated by Central Electricity Regulatory Commis-

sion (CERC). The preferential tariff regulations in MP & TN have stipulated tariffs which remain fixed over the tariff period and thus do not take into account of the impact of inflation/indexation on the cost structure during the control period. Also, wind zone based tariff principles have not been followed by SERCs across these key states, except Maharashtra and Rajasthan. In case of the MP, the steep downward revision in wind tariff is owing to revision in normative PLF assumption from 20% to 23% coupled with the downward revision in normative capital cost assumption from Rs. 59.6 million per MW to Rs. 57.5 million per MW. ICRA notes that reduction in preferential tariff by SERC is a negative development for new wind energy projects to be commissioned in MP, as it is likely to result into moderation in project IRR by about 360 basis points at a similar PLF level. The SERC in AP has approved the tariff for FY2017 at Rs. 4.84 per unit, which is similar to the tariff approved for FY2016 at Rs. 4.83 per unit. The minor difference in tariff is primarily owing to upward revision in normative assumption for capital costs and O&M costs as per indexation and downward revision in interest costs with decline in the benchmark rates.

Maharashtra and Rajasthan are yet to issue the tariff orders for wind power projects to be commissioned in FY2017. In case of Karnataka, the tariff approved at Rs. 4.5 per unit is valid till October 2018. As seen in Chart 2, project IRR for wind IPPs (who typically opt for preferential tariff plus GBI sale route) varies across the states depending upon the PLF level & preferential tariffs. The estimated IRR is highest in the state of Maharashtra and Rajasthan owing to relatively high tariff levels, while the estimated IRR for wind assets in Gujarat remains low due to relatively lower tariff. There is inconsistency in terms of tariff and policy across various states, which makes it difficult for the sector to grow according to the expectations, say experts. Preferential tariff norms across the key states are not consistent with the guiding principles/norms as stipulated by the Central Electricity Regulatory Commission, according to ICRA ■ (The report is base on ICRA report titled Wind Energy Sector: Feed-in Tariff decline in Madhya Pradesh & slowdown in signing of fresh PPAs in Maharashtra to negatively impact the capacity addition on all India basis in FY2017)

News Updates Ecoppia Opens Mass Production Facility in India Riding a wave of increased demand for their technology, Ecoppia - developer, designer, and producer of a pioneering robotic cleaning technology for utility-scale solar sites - inked a deal to begin mass producing their E4 robots at a new, stateof-the-art facility near Chennai, India. With the rapid growth of the solar industry in India, Ecoppia has seen skyrocketing demand for its E4 technology. The paradigm-shifting technology can clean an entire solar site in just a few hours, keeping solar energy production at peak efficiency. The deal, bringing together Ecoppia and new OEM partner Sanmina Corp, will see the majority of Ecoppia's production move to India. "We've seen demand grow across the board in 2015 - but

India remains our top market and the natural choice for us to build a state-of-the-art production facility," said Eran Meller, CEO of Ecoppia. "To do that we needed a strong partner, one that could help scale up production quickly. With Sanmina as our OEM, there's no doubt we're moving into a very strong market position." Ecoppia's E4 is the only bankable, effective and cost-effective solution in the important market of utility-scale PV panel cleaning. The industry has long been challenged by the need for consistent and water-free cleaning but reluctant to grant certification to technologies that may damage panels and impact energy production efficiency. Ecoppia has surmounted the problem, passing all industry tests and winning

blanket certification from every panel maker it's approached while maintaining international production standards. Sanmina, a Fortune 500 company and one of the world's leading OEMs, has a long history of manufacturing hardware, optics, electronics and clean technology for business clients and provides Ecoppia with a clear advantage in being able to quickly scale-up to meet the demands of India's, and the world's, largest solar projects. "The momentum we're seeing in the market suggests that Prime Minister Modi's goal of 100 GW of solar by 2022 will be achievable and we are excited that we can play a role in providing costeffective solar energy, bring new industry to India and create local jobs," said Ecoppia's Meller ■

Clean energy solutions are slowly and steadily spreading through different states and regions in India and are helping to create new jobs and industries even as they reduce carbon pollution and provide energy choices for households and businesses. For all of the recent success, achieving the target 175GW from renewable resources by 2022 will require the provision of unprecedented amounts of dependable, accessible, and fully-scaled capital. By conservative estimates, for India, to achieve the targeted generation capacities from renewable resources will require investment to the tune of $200 million over the duration of the target.

Currently a large scale solar or wind energy project gets a loan from Indian commercial banks with a high floating interest rate at about 12%. At the same time, the tenor of debt from these banks is not so long, it is only about 10-12 years. And when it comes to international financing, the higher costs of hedging can make the effective costs for international borrowing comparable to local sources. As per a report from the Climate Policy Initiative (CPI), these financing barriers can raise the cost of renewable energy in India by 24% to 32% compared with similar projects in the US. The Indian government has attempted to bridge this gap through a number of initiatives, such as the creation of Infrastructure Debt Funds and the National Clean Energy Fund. But, these have not been able to mitigate all of the financing woes, and the sector is still looking for

30â&#x20AC;&#x201A;SmartEnergy May/ June 2016

solutions. In order to achieve its targeted capacity addition from renewable resources India and its different states and regions need to find new ways to provide the financial support needed to shift the nationâ&#x20AC;&#x2122;s economy toward a lowcarbon future. One of the models, which draws inspiration from the Overseas Private Investment Corporation (OPIC) and several international experiments- entails the creation of clean energy finance banks or Green Banks that can combine scarce public resources with private-sector funds and then leverage the funds to invest in clean energy projects and energy industries.

What Is a Green Bank? A green bank is a public or quasipublic financing institution that ď&#x192;&#x153; www.supersmartenergy.com

provides low-cost, long-term financing support to clean, lowcarbon projects by leveraging public funds through the use of various financial mechanisms to attract private investment so that each public dollar supports multiple dollars of private investment. Depending on the state, a green bank may conform to a variety of structures, utilize many different public funds, and create a diverse array of financial products. Banks may utilize financial tools such as long-term and low interest rate loans, revolving loan funds, insurance products (such as loan guarantees or loan-loss reserves), and low-cost public investments or it may design new financial products. Ultimately, however, all green banks will exhibit several common characteristics: ii Stimulate demand by covering 100% of the upfront costs with a mixture of public and private financing; ii Leverage public funds by attracting much greater private investment to clean energy and efficiency markets; ii Recycle public capital so as to expand green investment and leave taxpayers unharmed; ii Reduce market inefficiencies; and ii Scale out clean energy solutions as fast as possible, maximizing clean electricity and efficiency gains per state dollar. The Green Banks can achieve several goals, including increased deployment of clean energy, more

efficient use of public funds, and animation of mature private financial markets for clean energy investing.

Practical Models for such an Institution Although a green bank may take a variety of forms, there are generally three structures to consider. First, as was done in Connecticut, the green bank can be standalone as a quasi-independent entity. The Connecticut’s Clean Energy Finance and Investment Authority was established in the year 2011 as a quasi-public clean energy finance authority that combines several existing state clean energy and energy efficiency funds, enabling the new entity to make loans, and to leverage its capital with private capital, permitting private investment in and alongside the bank with the investors receiving a reasonable rate of return on their investments. This structure allows for the most flexibility and autonomy. Another option is for the green bank to be housed within an existing state agency. This model repurposes portions of one or more of existing financing authorities from a grant to a lending model and then, through a partnership agreement, combines the financing authority’s funds with private funds. The New York Green Bank and Hawaii’s clean energy financing programs are examples of this model that operate within state agencies. Lastly, a green bank may be incorporated into an infrastruc-

ture bank, where it would likely be established as a separate subsidiary. This model is similar to the second except that it combines a clean energy investment bank to fund energy projects with a bank lending to traditional infrastructure projects like roads, pipelines, and transmission lines. Under all these models, there are ample new market and profit opportunity for regional and commercial banks as well as community banks.

Role of a Green Bank The clean energy industry faces unique challenges in that it is highly asset-based and capitalintensive. What is more, most clean energy technologies face long technology and cost curves that more often than not deter private capital from investing either in a collection of small scale or in a handful of large scale clean energy projects. As a result, despite the recent success of these new technologies in reducing their production and operating costs, in most cases the delivered cost of energy from clean energy projects remains higher than the delivered cost of energy from existing power generation facilities. In light of these broad technology and pricing challenges, clean energy projects face both high capital needs and a scarcity of reasonably priced capital at every phase of the development pipeline from the research and devel-

Finance opment phase to widespread market adoption. The So-called “clean energy finance banks” or “green banks” are ideally suited to solve this problems because they offer a practical way for states to make available leveraged, low-cost financing for project developer. First, they can be developed out of existing state programs while bringing into the enterprise the equivalent of substantial new resources given their ability to leverage funds. Likewise, because the banks would provide debt financing, they would be repaid on their loans, putting them in the position to borrow funds and to establish revolving loan funds that would provide funds that could be reinvested without new sources of financing. Furthermore, Green Banks, if established as independent institutions, would be able to issue revenue bonds without the full faith and credit of the state and without the restrictions facing

states, which have limited borrowing capacity. Finally, clean energy finance banks could efficiently seek large investors with patient, long-term capital who are seeking a long-term, conservative rate of return, such as pension fund investors.

Banks offer a practical way to make available low-cost financing for project developers and keep the clean energy economy growing.

Green Banks, in this regard, hold great promise for financing deployment of clean energy projects with low technology risks, including projects using existing wind and solar technologies. Such clean energy projects, because of their low technology risk and low financing risk should be able to attract bond purchasers interested in long-term, safe returns and thus willing to accept rates of return at a conservative level. By providing standby purchase agreements or total return swaps, the clean energy finance bank could even increase the potential pool of tax equity investors by lowering the risk profile of such investments.

In order to generate 175 GW of renewable energy by 2022 and to reduce greenhouse gas emissions intensity by 33 to 35 percent from 2005 levels by 2030, India has set ambitions goals for five key sectors: 1) ground-mounted, large-scale solar, 2) rooftop solar, 3) off-grid solar, 4) wind energy, and 5) energy efficiency. Green banks are designed to address local market and policy failures, tailored to the specific context. As has been demonstrated internationally, green banks can provide financing solutions to help each specific sector grow in India. Not all will be appropriate to the Indian context, actual opportunities will be determined through detailed market research.

CONNECTICUT’S CLEAN ENERGY FINANCE AND INVESTMENT AUTHORITY (CEFIA) About CEFIA CEFIA is a quasi-public financing authority that provides financial support to clean energy projects in the state of Connecticut. CEFIA’s goal is to attract and deploy private capital to finance clean energy projects in Connecticut so that clean energy may be affordable and accessible to all consumers. CEFIA’S Scope and Characteristics CEFIA’s programs support projects that focus specifically on clean energy. Types of projects funded: CEFIA generally funds projects that use proven technologies that have existing, yet limited, deployment opportunities, rather than technologies that are still in early development or demonstration stages. CEFIA is authorized to finance up to

32 SmartEnergy May/ June 2016

80 percent of clean energy project investments and up to 100 percent of energy efficiency project investments, although the bank aims to provide “a tranche of the debt financing wherever possible and not 100 percent of the loan” for all of its investments. As CEFIA programs develop and demonstrate success, private investors are likely to offer increasing proportions of finance to clean energy project deals. Financing tools offered: Examples of financing tools include direct lending and co-lending, on-bill financing (coming April 1, 2014), credit enhancements, and commercial property-assessed clean energy (C-PACE) programs Risk Management CEFIA utilizes a variety of mechanisms, particularly reserves and

credit enhancements, to manage and reduce its risk. In doing so, CEFIA attracts private investors to clean energy projects. As CEFIA makes more financial transactions, creating a larger sample and longer track record, it will be able to better estimate how much risk it needs to take and adjust its risk management activities (such as reserve rates or payback timescales) accordingly. Selected Programs CEFIA has funded a variety of energy efficiency or renewable energy projects. Some examples are as below › Dominion Bridgeport Fuel Cell Park: › Residential Solar Investment Program (RSIP) and many others ■

ii Reduce cost of domestic capital by of¬fering lower rates, fixed interest rates, and longer debt tenors to attract inter¬national investment. ii Mobilize attractive debt capital ii Serve as a foreign-exchange hedging facility to reduce currency risks ii Mitigate risk through credit enhance¬ments tools such as guarantees ii Increase transparency ii Share best practices, information and data about project technology and performance to help grow the market ii Facilitate warehousing to aggregate small rooftop installation projects into larger projects attractive for investors ii Facility development of business mod¬els based on leasing and third party financing for rooftop solar PV at lower costs to over-

come investment barriers ii Work with utilities, distribution com¬panies, states and municipalities to develop and implement rooftop solar programs based on property taxes, on-bill charges, etc. ii Green Banks can work with MNRE to fa¬cilitate grid infrastructure for wind power ii Pool wind farm assets to facilitate repayment

Conclusion One of the greatest benefits of the Green bank model is its ability to leverage investment from and share costs with private investors. This, in addition to offering return-generating financing tools, allows for the most efficient and least risky use of public and private funds. Green Banks set themselves apart by utilizing a revolving fund, meaning that programs aim to eventually be self-sustaining,

eventually requiring no additional outside capital. Moreover, because they are able to afford more risk than the private sector, Green Banks have the potential to experiment with a variety of finance mechanisms, not only improving upon existing ones, but developing entirely new tools for the market to work to adopt in subsequent years through the green banks’ help. Despite these key characteristics, the effectiveness of Green Bank will be hindered without continued government support for clean energy. The government’s policies, incentives, and resources are an existing structure upon which Green Banks build their operations. While Green Banks have potential to accomplish clean energy goals, India will still need a big picture framework for the transformation of our energy system ■

INDIA POISED FOR Rapid Growth in

Energy Storage

34 SmartEnergy May/ June 2016

 www.supersmartenergy.com

India is a rapidly developing energy hungry nation. On the one hand we have industrialization and development and on the other hand there are over 400 million people with no access to electricity. With the PM promising to provide each household with at least one light bulb by 2019, renewable energy is set to plan an important role in fulfilling this dream. Energy storage is going to be a critical link in providing electricity to the remotest location and in transforming the nation towards a clean and sustainable future. In this article Rohan Singh take a look at the rapidly growing energy storage market in India, the key drivers and the challenges in capturing the full value of energy storage technologies.

enewables have been remarkably successful in providing a sustainable solution to our energy needs. Tariffs are falling and we have huge deployment of renewable energy spread across the country. We have about 300 sunny days a year and a number of good wind sites. Hoping to make productive use of its geographical advantages, India has scaled up its target to generate 175 GW through solar and wind by the year 2022. Everything looks rosy but there is a missing link in this success story. The sun doesn’t always shine, and the wind doesn’t always blow. A power plant requires the continuous source of fuel to be commercially viable .But call it the paradox of nature, you can’t control the supply of solar or wind, despite they being abundantly available. Sometimes it may be cloudy, or the wind may not be blowing, or it may be the night time. And electric grids cannot function unless they are able to balance supply and demand. Any imbalance can result in voltage fluctuations and inconsistency in the power supply. High intermittency of renewable energy makes

its supply uncertain and the grid unstable. One of the most effective solutions for addressing this high intermittency while allowing scale up of these technologies is the use of energy storage systems. Energy storage can act as a capacity in the entire energy value chain from generation to transmission, distribution and loads.

What is Storage?

Energy

Electricity storage is a three-step process that consists of drawing electricity from the grid, storing it and returning it at a later stage. It consists of two dimensions: the power capacity of the charging and discharging phases, which defines the efficiency of the storage system to withdraw or inject electricity instantaneously from or into the grid; and the energy capacity of the storing phase, which measures how much energy can be stored and for how long. As a consequence, electricity storage has very different uses, depending on the combination of the power rating and discharge

NTPC STORAGE SYSTEM

Globally Energy Storage Technologies are expected to play a crucial role in shifting to large scale renewable energy. They can help manage the problems of fluctuating generation and regulating generation to match demand. All major economies have specialized focus on this area. Mckinsey has identified storage technologies as one of the 12 most important technologies for future.

India's largest energy conglomerate National Thermal Power Corporation (NTPC) seems to be taking inspiration from Tesla. The company is developing a battery that can store the energy from the solar plants. NTPC ltd will soon call bids to set up such a megawatt level storage facility in Andaman and Nicobar islands. Megawatt scale batteries are already available but they are costly. NTPC wants to develop a storage system which is technically and commercially viable .Although the project is at the R&D stage only , NTPC is in serious talks with Tesla to use their expertise in the matter. NTPC's plan is believed to be a part of India's overall energy strategy which aims at generating 100 GW of solar energy by the year 2022. This will also help in bringing the solar tariﬀ further down. NTPC is also studying the grid scale battery storage solution.The project will be awarded on the basis of competitive bids.

Benefits of Energy Storage Systems Power Quality and Reliability: Grid connected power quality events are voltage sags and interruptions with durations of less than 2 seconds, phenomena that lend themselves to energy storage-based solutions . Load Shifting: Load shifting is achieved by utilizing EES for storage of energy during periods of low demand and releasing the stored energy during periods of high demand. Load shifting comes in several different forms; the most common is peak shaving. Frequency - In grids with a significant share of wind generation, intermittency and variability in wind generation output due to sudden shifts in wind patterns can lead to significant imbalances between generation and load, that in turn result in shifts in grid frequency. Such imbalances are usually handled by spinning reserve at the transmission level, but energy storage can provide prompt response to such imbalances without the emissions related to most conventional solutions. Transmission Curtailment Reduction: Wind power generation is often located in remote areas that are poorly served by transmission and distribution systems. As a result, sometimes wind operators are asked to curtail their production, that results in lost energy

production opportunity, or system operators are required to invest in expanding the transmission capability. An Energy Storage Systems unit located close to the wind generation can allow the excess energy to be stored and then delivered at times when the transmission system is not congested. Time Shifting: Wind turbines are considered as non-dispatchable resources. Energy Storage Systems can be used to store energy generated during periods of low demand and deliver it during periods of high demand. Energy storage can act as a capacity in the entire energy value chain- generation, transmission, distribution and loads. The greater use of storage will help the transition from centralized generation to distributed generation with attended benefits of improving energy access and availability, security, quality and efficiency.

Types of Energy Storage Systems:

36 SmartEnergy May/ June 2016

Energy Storage is a technology that has been adopted for many years. The technology used behind ESS includes Compressed Air Energy Storage (CAES), Flywheel, Pumped Hydro and batteries. Compressed Air Energy storage (CAES) systems use off-peak electricity to compress air, storing it in underground caverns or storage tanks. This air is later released to a combustor in a gas turbine to generate electricity during peak periods. Flywheels are mechanical devices that spin at high speeds, storing electricity as rotational energy. This energy is later released by slowing down the flywheel’s rotor, releasing quick bursts of energy (i.e. releases of high power and short duration). Pumped storage hydropower (PSH) systems utilise elevation changes to store off-peak electricity for later use. Water is pumped from a lower reservoir to a reservoir at a higher elevation during off-peak periods. Subsequently, water is allowed to flow back down

ium-ion, lithium polymer), sodium sulphur, and lead-acid batteries. Currently battery has become main stream as technologies such as NaS, Lithium-ion, Lead-acid and flow batteries have begun to participate in various worldwide projects.

Lithium-ion is a well established technology for portable electronics but is still finding its role in larger scale applications; it is emerging as a contender in certain stationary applications where volume, weight, temperature sensitivity or low maintenance is more important than initial cost. Given the significant differences in technical and economic characteristics of the battery types, it stands to reason that the “best” solution for which battery type to use is application specific. Lithium-ion has significantly higher cycle life than lead acid in deep discharge applications. The disparity is further increased as ambient temperatures increase. The cycle life of each chemistry can be increased by limiting the depth of discharge (DoD), discharge rate, and temperature, but lead acid is generally much more sensitive to each of these factors. When determining what capacity of battery to use for a system, a critical consideration for lead acid is how long the system will take to discharge. The shorter the discharge period, the less capacity is available from the lead acid battery.

Lead acid batteries compare poorly to lithium-ion with regards to environmental friendliness. Lead acid batteries require many times more raw material than lithium-ion to achieve the same energy storage, making a much larger impact on the environment during the mining process. The lead processing industry is also very energy intensive, leading to large amounts of pollution. Although lead is highly hazardous to human health, the manufacturing methods and battery packaging make the human risk negligible. On the plus side, majority of lead acid batteries are recycled, which makes a huge impact on the environmental equation. Though, Lithium is also not without its own environmental problems and it is expected that that lithium-ion recycling rates will rival lead acid. The general conclusion of the comparison is that while the most cost effective solution is dependent upon a number of factors, there is a large market segment where lithium-ion has a lower cost of ownership when compared to lead acid.

Cover Story to offset the cost of their electric usage with energy they export to the grid. So far, around 14 States have released net metering policies which give consumer a provision to install Rooftop PV at their premises. Most of such systems will involve energy storage systems like inverters with batteries. The Ministry of Power has approved National Smart Grid Mission (NSGM) which has set aggressive targets for Micro grids which will require energy storage technologies. Microgrids will play an important role in solving energy problems in India. Microgrids along with storage will allow for fast installation of electricity supply without the need for expensive transmission infrastructure investments and the lengthy development approval and construction process. In COP21 in Paris, India specifically mentioned development of Energy Storage Systems for Renewable Energy as one its key commitments for reducing carbon emissions to a tune of 33% to 35% by the year 2030 as compared to 2005. As part of this effort, MNRE released Expression of Interest for demonstration projects last year, which received tremendous response from all the stakeholders. The Ministry of New & Renewable Energy (MNRE) is also in process of gathering inputs from various stakeholders to introduce specific policies to fast track adoption of storage technologies in India. India is still in the earliest stages of energy storage deployment. Right now there is push for renewable especially Solar from the Government & if it really works the way we are aiming, there will be a huge explosion in demand and with that we need storage, otherwise it will not work.

Conclusion: The total energy storage market between 2015 and 2022, in India

is estimated by India Energy Storage Alliance (IESA) which is close to 70GW and 200GWh. Out of 70GW, over 35 GW of demand is expected from newer applications like wind and solar integration, frequency regulation, peak management, T&D deferral, diesel replacement and electric vehicles. Hence there is a sizable opportunity for advanced storage technologies in the new applications itself apart from opportunity for existing technologies to improve their performance for traditional applications. Lack of reliable grid power, growth in sales of electric rickshaws (e-trikes), reduction in use of diesel gensets and integration of solar PV with the grid at both ground level, roof-top level and at micro-grids is likely to boost the sales of battery based energy storage through-out the country. Some of these applications are growing at over 35% year on year. Advanced energy storage technologies have already started penetrating the Indian ESS market with Li-ion already being implemented in telecom towers. Flow batteries likely to gain market in diesel replacement, micro-grid and solar integration market in couple of years. Nickel based batteries are gaining momentum in applications like standby support

for C&I consumer. The Indian market is slowly gaining understanding of both the newer energy storage technologies and their applications. The market stake holders want to witness the proof of concept. For this to happen, the policy makers and the government need to step in with demonstration projects and incentives like Viability Gap Funding (VGF), Accelerated Depreciation (AD) benefits, etc. for the energy storage projects. At the same time, many factors influence the deployment of energy storage beyond technology cost and performance. The widespread deployment of these technologies is particularly dependent on achieving acceptable cost recovery. Current policy environments and market conditions often cloud the cost of energy services, creating significant price distortions. A key to achieving widespread storage technology deployment is enabling compensation for the multiple services performed across the energy system. A patchwork approach to creating an energy storage market will not be able to capture the full value of energy storage technologies â&#x2013;

Changing the Energy Landscape Authored by: Anil Kadam

microgrid manages distributed energy resources and interconnected energy loads within a defined electrical boundary like a campus or business park. Distributed energy resources can include both traditional fossil fuel generators and renewable energy resources, like solar, working together. This intelligent system operates as a single controllable entity working in parallel with the utility grid or in an optional islanded mode where it disconnects from the grid and operates under its own power. In short, it keeps the electricity flowing to critical loads regardless of available utility services. Think of a microgrid as a conductor working to keep your energy system in harmony. That means carefully balancing supply and demand in both on-grid and

islanded modes, as well as safely managing the switch back and forth, all while maintaining power stability and quality to protect your infrastructure and equipment. Energy users are quickly realizing the importance of local energy generation and managing renewable energy resources efficiently. Severe storms, power outages, aging energy infrastructure and rising costs have created a period of energy uncertainty. In today’s high-tech world, our prosperity and well-being depend on an uninterrupted flow of low-cost electricity. Introduction of microgrids is shifting control of our electricity system to the end user, making it more decentralized and democratic. These solutions are providing large electricity consumers with energy independence, where power is more reliable and stormresilient. And while it’s critical to have back-up generation when the

42 SmartEnergy May/ June 2016

central grid fails, there are also many other benefits that come with microgrids and distributed energy generation. Distributed energy resources (DER) and microgrids are proliferating rapidly within utility distribution systems and the benefits to the utility results in reverse power flow and also impact the voltage system of an electrical distributor. Utilities are therefore faced with the challenge of planning for and coordinating these diverse resources - such as microgrids and mitigating their impacts on the distribution network.

Micro-grids In spotlight We need to consider the below trends which have emerged in the energy sector: ›› Willingness to reduce dependency on imported fossil fuels by switching to local renewable energies  www.supersmartenergy.com

›› slow progress of electrification that makes new approaches to it mandatory These trends have brought the so-called microgrids back into the spotlight. A type of electrical grid that involves integrating smaller, self-generating grids, they are integrated energy systems that interconnect Distributed Energy Resources (DER). Under this term are controllable loads, generation that can come from renewables, and other disruptive technologies such as batteries and electric vehicles. Microgrids comprise elements such as energy storage, Heating, Ventilation, and Air Conditioning (HVAC), factories that operate using their own photovoltaic generation, wind power, and residential consumers themselves. The combination of these controllable loads, local generation, and storage points can substantially reduce transmission losses thanks to their close proximity to end users. Microgrids can be permanently or temporarily isolated from the main grid and supply themselves with their own energy at particular times. In the event of main grid supply failure, for example, microgrids can maintain supply internally by carrying out load shedding of specific resources, if needed, to maintain their balance. In addition to operating independently, microgrids can operate in parallel with the main grid. The consequence of this flexibility is smarter energy management: local power generation can be managed in line with local demand, minimizing exchanges at the point of connection between

microgrid and grid, and thereby freeing grid resources. Although microgrids are conceptually similar to large grids, their small size makes them prone to instabilities. For example, whereas in the main grid the largest generation asset represents less than 3 percent of total generating capacity, in a microgrid it might be more than 20 percent. This makes resilience to its loss much more difficult to achieve. With a large share, if not all, of its generation being variable renewables, such as wind or solar, a smart microgrid based on four basic pillars becomes necessary: a smart network, smart operations, smart metering, and smart generation. Thanks to sensors and automation, a smart network is flexible and provides the control mechanisms required to improve load distribution or effectively accommodate changes in the network in milliseconds. Smart metering delivers real-time information about consumption and trends. Smart generation contributes to overall stability thanks to ancillary services. Smart operation is the conduc-

tor that enables all of these new elements to work together, thanks to forecasting and overall optimization, and to integrate into the traditional grid. With those four pillars in a subset of the main grid, a utility and its networks will see reduced energy losses, improved service quality, strengthened resiliency, higher renewable penetration, and might even be able to defer some investments in substations and network reinforcement. For microgrids to successfully operate as off-grid entities, their implementations must fully apply those concepts and controls. Boiled down, useful microgrids require two main ingredients: the management of demand and a dynamic approach to overall system configuration ■ About the Author:

The world today is discovering several advantages of switching over to LED technology from CFLs and other means of conventional lighting, the immediate one being energy efficiency. Where the public lighting infrastructure

already exists, conversion to LED technology is increasingly underway or planned. For instance, the city of Boston, by the end of 2012, had converted 40% of its 64,000 electric street lamps to LEDs, resulting in about 35% savings ($2.8 million) in annual electricity costs. Efficiency and Savings In spite of higher initial investments compared to conventional lighting, LEDs work out to be more cost effective due to their longevity and other benefits like being more energy efficient, safer to use and cheaper maintenance cost. Unlike earlier street-lighting technologies, LED lamps can be dimmed, creating new opportunities to integrate smart public lighting into smart cities for even greater power savings. Under the older technology, all the high-intensity discharge lamps were either ON or OFF, thereby allowing public lighting departments to choose the times to turn all the lights On and Off. The LED streetlights, in contrast, provide variable output

levels, thus opening up opportunities for innovative schemes that provide appropriate light for safety and convenience without wasting energy by producing more light than is needed. Since they can be integrated with sensors and remote controls, the LED lights could be switched On, Off, Dimmed or Brightened (as programmed) during varying hours of the day or in different seasons. The usage of LEDs as street lights, at homes and in offices within the smart cities can lead to savings of around 30 % annually, according to experts and the companies engaged in their production. Besides, smart street lighting can be integrated with intelligent systems like the traffic light controls, closed circuit cameras, among others. This will require the smart lights to be based upon open, adaptable systems through which the smart LED lighting could become an integral part of the Internet of Things (IoT). Lighting and other devices will need to be IOT-ready to form an intrinsic part

Smart Cities of the Smart Cities programme, thus making the operators more efficient, smarter, safer, sustainable and innovative. This “Smartification” will further enable the illumination of various urban areas precisely, according to needs and in a concerted way. Light masts as recharging stations for vehicle batteries Reports say that these urban LED solutions for lighting can take a significant step further, providing not only major energy savings potential but also new services for citizens. Lantern posts can become multi-functional stations that in addition to providing traditional lighting can also serve as data stations with sensors, monitor parking spaces and communicate information about these, or recharge the batteries of an electric car. Street light in residential areas can be controlled according to the density or speed of vehicles. Light can be dimmed, for example, if few cars are driven at night. This saves energy overheads. A right balance will be essential between benefiting from innovations and managing new safety, security, privacy and performance risks as the cities absorb newer technologies. There is a possibility

of interconnection, leaving lighting systems vulnerable to cybersecurity attacks, from low level threats such as a neighborhood kid hacking into a home’s smart meter system and switch lights on and off as a prank, to a higher level threat like a criminal hacker penetrating a hospital and taking control of the lighting system. In one of the initiatives to combat smart city cybersecurity risks, UL is working with the National Electrical Manufacturers Association (NEMA) to modify existing urban standards and develop new standards to secure the connectivity and interoperability of street lights. It is further developing safety and security standards for street light manufacturers by introducing Internet-connected light poles that will serve as wireless networking access points to enable citizens and city managers to take advantage of ubiquitous connectivity. How UL can help to validate product for right decision making while choosing energy efficient and safe products:

per various National/International standards such as IES LM-79, IS 16106 to verify the correct Lux levels as well as to verify the electrical characteristics of various Indoor/Outdoor LED Lighting products thus making them safer and more energy efficient. IES LM standards as well as IS 16106 are used to verify the Colorimetric and Photometric characteristics of the LED products. Lighting recommendations as per the National Lighting Code are as below for Outdoor Luminaires Safety Testing for Luminaires: UL can assist in making product more safer by testing as various standards like IEC 60598/IS 10322, which consists of various tests as indicated below: ii Endurance Test to verify the reliability of various components in the end product ii Thermal Test to verify the thermal properties of insulation and various other components

Life and performance of the Lumaire is dependent on how the Controlgear performs within the product. UL also tests ControlGear used in the LED Luminaire for its Safety as well as Performance characteristics. IS 15885/IEC 61347 is being used to test for safety requirements and IS 16104/IEC 62384

is being used to evaluate Performance characteristics. Common tests being conducted for Controlgear are as below: ii Transformer Heating to verify the thermal characteristics of the Transformer ii Fault Condition testing to operate the components in various possible faults like Open Circuit, Short Circuit, Overload/Under load etc.

with building automation and energy management. These interlinked technologies must be governed by safety standards to realize the full potential of a smart city and drive innovation further. With the government’s Domestic Efficient Lighting Programme gaining ground, smart lighting could perhaps be taken beyond the chosen smart cities, thereby putting India on the global map for energy efficiency.

Photovoltaics Case Study

Water-free PV Panel Cleaning: Better for Everyone Authored by: Eran Meller

rime Minister Modi’s commitment to deliver 100 GW of solar by 2022 is inspiring and exciting, and is transforming India into a global leader in clean energy. Elsewhere, however, the nation still faces extreme challenges in many areas of basic infrastructure – access to clean drinking water being perhaps the most urgent of these. While these two issues may on the surface seem unrelated, they in fact intersect, with important implications for the future of the solar industry. PV panels need to be clean in order to transform sunlight into energy. Even minor buildup of dust over a few days can negatively impact the production efficiency of panels. If dust is left to accumulate on panels, the production efficiency can drop by 30% or more, meaning solar sites are not producing as well as they could be. The result is lower energy produc-

tion- but also lost revenue for the companies that invested to build those farms in the first place.

that can continue and why solar companies must move to waterfree solutions.

Unfortunately, the primary method of cleaning solar PV panels is with a mop and water – lots of water. A single large-scale utility solar park of 100 MW (providing power for potentially over 100,000 homes) can expect to use 355 million liters of water throughout its lifetime. Some of that might fall from the sky- but the vast majority of it has to be brought in by tanker trucks or supplied via local water wells only to be sloshed liberally over the panels. In various locations all over the country, right now, teams of workers are pouring water onto solar panels and scrubbing them free of dust and dirt. When those same workers return home at night they might not have water to drink.

First and foremost, solar site operators will not be able to continue to use water for cleaning when the people in the nearest village don’t have it to drink, cook, or clean. It must be preserved so that it can be provided where it is needed the most. So urgent is the need that eventually companies will be forced to find alternative solutions or else deal with disruptions, protests and theft as waterpoor people living nearby learn of the resource and resent how it’s being used.

In a country under such water stress, this is simply not a solution

48 SmartEnergy May/ June 2016

The good news is that there’s an also strong economic reason for companies to abandon waterbased cleaning solutions. Using water to clean panels doesn’t just mean companies need to purchase the water. They also need to transport it, not an insignifi www.supersmartenergy.com

damage to panels. Sites maintain peak production efficiency without wasting water. To ensure that there’s no question of the benefit, we also developed the robots to operate under their own solar module and battery, keeping operation costs extremely low.

There’s also an inherent cost to cleaning panels using manual laborers and brushes in that laborers, being human, occasionally make mistakes. Panels can be damaged. Even micro fractures caused by harsh brushing can quickly come to impact the production efficiency of the solar module. If modules have been impregnated with an anti-reflective coating, brushes can destroy its benefits in months.

The idea is catching on. Given the choice between sloshing millions of liters of water over solar panels and a cheaper option that uses no water and provides better results, companies are responding accordingly and working to incorporate our solution at their sites. This year Ecoppia is on track to deploy its technology with several of India’s largest energy players, with many more in the pipeline.

The Ecoppia autonomous solution is tackling these problems head-on. We developed a PV panel-cleaning robot that uses no water while providing a consistent, nightly cleaning that ensures no

That’s good news for India’s clean energy future and the state of the water resource. On the one hand Ecoppia is helping to make clean energy even cleaner, and on the other hand preserving water for where it’s needed the most.

Providing water-free solar site cleaning is a win-win scenario, and the sooner it’s adopted, the better it is for both the booming solar industry and the people of India ■
