India is advancing regulatory and industrial frameworks to support renewable energy integration through battery storage. The Central Electricity Authority (CEA) has proposed draft regulations for solar and wind projects commissioned after July 1, 2027, requiring a minimum battery storage capacity of 10% of installed capacity. These rules also mandate that at least 15% of inverters operate in ‘grid-forming’ mode, with stricter storage duration requirements planned for projects commissioned between 2029 and 2031.

In the industrial sector, Premier Energies and RCT India have entered a joint venture to establish a 12 GWh battery energy storage system (BESS) manufacturing facility in Telangana. The project will be implemented in phases, with an initial 6 GWh capacity expected to be operational by June 2027. The facility aims to serve domestic and international markets, providing storage solutions to address energy intermittency and grid flexibility.
