Over the past 5 years, various state agencies as well as central government departments including MNRE, MOP, NITI Aayog have been working on aspects related to energy storage policy. Currently, MNRE is also working on National Energy storage Mission and on various tenders. Battery energy storage systems have gained increasing interest in world of electricity and mobility market. Lithium-ion batteries have evolved rapidly with a wide range of cell technologies and system architectures available on the market. Lithium is the lightest of all metals, it has the greatest electrochemical potential and provides the largest specific energy density. Due to its high energy density, long cycle life, better performance and high thermal safety Li-ion batteries have become the most promising and fastest growing battery technology in market. Coslight India, a pioneer in Advanced VRLA and Lithium-Ion battery manufacturing has developed and designed high end customized energy storage solutions. These cater to various domains especially Renewable Integration, Mega Watt hour solutions, Microgrids energy access and campuses, Minigrid ancillary services and EV charging infrastructure.
