Energy Storageadaptations in India India Energy Storage Alliance (www.indiaesa. info) was created in 2012 with a conviction that energy storage technologies can help India leapfrog the modern grid development. India has recently grabbed global attention through early adoptors such as Reliance Jio, who has purchased Li-Ion batteries worth $300 M for the new 4G telecom towers and Sun Edison that has just recently announced plans to deploy over 1000 flow batteries from Imergy Power for microgrids in India.Power Grid Corporation of India Ltd. has successfully conducted RFPs for selecting 3 different storage technologies of 500 KW for ancillary service demonstration project. Recently ACME successfully installed a 270 Kwh of Lithium Ion battery in its building to reduce diesel consumption in Gurgaon, India. Surprisingly, India has more than 3 lakhs of e-rickshaws on the road in various cities like Delhi, Lucknow, Kolkata and many other tier 2 and 3 cities in India. Few car companies like Toyota, Mahindra and Maruti are launching various electric cars in Indian market and the sales growth is also encouraging over the period. Indian market is highly price sensitive. Taking the past examples like mobile phone growth in India, it is evident that India’s adaptation rate is higher than many developed countries which result in fall in price and higher technology innovation. India first used advanced energy storage technologies like Lithium Ion in the telecom sector to avoid high diesel prices in telecom tower, where power cuts are more than 6-8 hours per day. Over the years, many rural and remote telecom towers installed battery systems in India. Both financially and technically energy storage installation in telecom sites provided better options for the telecom tower operators. We are seeing that Commercial and Industrial consumer are the next consumer segment to adopt large scale energy storage systems. To avoid power cuts, to meet peak loads and to gain arbitrage advantage over ToD tariff difference, C&I segment is installing advanced energy storage technologies in their premises. It’s also giving them benefit to integrate with their captive solar plant and also to eliminate traditional lead acid battery used in installed UPS. This C&I segment for Industries and Commercial building like Hotel, Hospitals etc. have a huge potential in India. In addition to this large housing society and apartments are the next adopters of large scale energy storage system in India. Technology Innovation can only boost Indian ESS Market Currently India accounts for 4 GW+ solar energy and 23 GW+ of installed wind generation. With a target of 160 GW of installed renewables (Solar and Wind) by the year 2022, the Indian Government is taking all steps to boost this market. In addition, under the FAME India Initiative (National Electric Mobility Mission Plan) the government has set up a target of achieving over 15-16 million electric vehicles on the road by the year 2020. Interestingly, the bottleneck for large scale incorporation renewables generation and electric vehicles is the same. It is energy storage or as we all know it; batteries. Utilities do not have control on whether the sun shines or the wind blows and hence it has been difficult to fully incorporate solar and wind power seamlessly into the electricity grid. Addressing the inherent intermittency of renewable resources is a key enabling factor for large scale adoption. Several energy storage technologies are currently available and continuous developments in this field are bringing us closer to the overall objective of providing clean and sustainable energy for all. For electric vehicles, having batteries with long cycle life, light weight and appropriate safety characteristics can bring electric vehicles within the reach of the common man. Of course, it will need support from the appropriate agencies and government bodies for developing the required ecosystem and charging infrastructure. As of now, the lead Acid battery accounts for more than 90% of the Indian energy storage market. However, advanced technologies like Li-ion, Flow batteries (Vanadium Redox, zinc bromine) and Sodium sulphur are also entering this market with a few pilot projects and in limited segments. India Energy storage Alliance (IESA) is playing the role of providing a national platform where various key stakeholders can come together in realizing the required growth for achieving the aggressive targets laid down by the government. Price reduction of energy storage technologies will play a key role in promoting their widespread use on the grid scale. Such price reduction can be achieved through innovations in materials processing techniques, manufacturing methods, as well as improvements in performance characteristics (such as cycle life, calendar life, energy density). Such improvements can bring about a reduction in the levellised cost of the system and similar trends have been observed in the last two decades in renewables such as solar and wind power. Capital cost Trend for Various Technology Large investments from various organisations like ARPA-E and DOE (US) has been pouring in to bring innovative solutions to the market. India is also not far behind. Recently, U.S.-India Partnership to Advance Clean Energy (PACE) program expanded to include a new track on smart grids and energy storage under the Joint Clean Energy Research Development Centre. Many private companies starting their own innovation centers and Incubation center to facilitate innovators to work and bring changes in this space. Several companies are also working in the field of improving the BMS, charge controller systems, monitoring software and battery recycling to advance this overall ecosystem. The Way Forward India Energy Storage Alliance (IESA) estimated that India ESS market potential will be 50 GW by 2022. We also believe that India has the potential of not only becoming the one of the largest markets for advanced storage technologies, but also a key player in the global supply chain through localization and innovation in the energy storage field. Indian PM Mr. Modi and Elon Musk’s meeting and discussion on Tesla’s Powerwall is buzzing around the web. Recently Elon musk also tweeted that Tesla might open a manufacturing plant in India seeing a huge demand of batteries in this sub-continent. India already boasts a very vibrant Lead Acid manufacturing industry with global leaders such as Exide and Amara Raja supplying lead acid batteries to over 35 countries around the globe. Ministry of New and Renewable Energy is currently working on a policy framework on storage and has created a standing committee on energy storage and hybrid system. Ministry of heavy Industries is working on the National energy Storage mission and Energy storage roadmap. With this right policy support, Indian Industry and Research community have the potential to deliver solutions that will not only address the challenges faced by consumers in India, but also become a global hub for advanced energy storage solutions by 2020 ENERGY STORAGE 54 energetica INDIA · SEP | OCT15
