ENERGY STORAGE World Energy Storage Day and its Significance for India The recent pandemic related to COVID19 has highlighted the importance of domestic manufacturing considering the risk of global supply chain disruptions. Energy storage and EVs have importance for national energy security and we should learn from the recent events and accelerate our efforts for building domestic capabilities. 60 energetica INDIA- September_2020 4th World Energy Storage Day With a rising focus on the effective inte- gration of renewable energy, the impor- tance of electric vehicle and reliable, resilient energy supply, energy storage is becoming an increasingly important tool in the electricity ecosystem. With energy storage rising to the forefront of industry developments, World En- ergy Storage Day was celebrated on 22nd September every year by various global industry stakeholders, policy makers, think tanks and associations to acknowledge its importance across the globe. On the 4th World Energy Storage Day, India Energy Storage Alli- ance (IESA) organized a one-of-its-kind global conference & expo to develop a global ecosystem for energy storage and e-mobility markets. The event was held virtually on September 22, 2020 across four regions encompassing ses- sions on Policy and Government Initia- tives, Stationary Energy Storage Panel Discussion, E-Mobility Panel and latest innovations and developments in the energy sector. 2019 Nobel Laureate in Chemistry, Dr Stanley Whittingham was the key speaker who is currently work- ing as a professor of Chemistry in Bing- hamton University, State University of New York. The event brought together 75+ global thought leaders and policy makers to share insights on the policy, technology, and business landscape in each of the four global regions. The Answer to our Energy Woes Energy storage is often used to improve power access and intermittent power. It can be used to help the grid return to its normal operation after a distur- bance. In addition to stabilizing the grid after disturbances, energy storage can also be used to support normal opera- tions of the grid such as injecting and absorbing power to maintain grid fre- quency in the face of fluctuations. At the transmission level, storage asset can provide power for up to two hours in response to a sudden loss of gen- eration or an outage. Load shifting is achieved by storing energy during pe- riods of low demand and releasing the stored energy during periods of high demand. There is sizable potential for advanced storage technologies in new applications apart from the opportuni- ty for existing technologies to improve upon their performance for traditional applications. Emerging energy storage systems may provide several techni- cal benefits. Advanced energy storage technologies have been making their entry into the market with Li-ion being widely implemented in telecom towers and portable electronics. Flow batteries are being preferred for diesel replace- ment, microgrid and solar integration while Nickel based batteries are gaining momentum in applications like standby support for Commercial and Industrial applications. A major application of En- ergy Storage lies in the integration of in- termittent renewable energy sources for applications including wind power and solar energy. In grids with a significant share of wind generation, irregularity, and variability in generation output due to unpredictable changes in wind pat- terns can lead to imbalances between generation and load that in turn result in irregularities in grid frequency. Energy storage can provide a quick response to such imbalances and irregularities without the harmful emissions and negative environmental effects of most conventional solutions. Also, since wind power systems are often located in re- mote areas that are poorly connected by transmission and distribution sys- tems, sometimes operators may be asked to curtail production, resulting Debi Prasad Dash Executive Director, India Energy Storage Alliance (IESA)
