The Solar Energy Corporation of India (SECI) has invited a tender for 2 GW of grid-connected solar projects with co-located battery storage. The Central Electricity Authority had earlier recommended co-located storage to manage solar intermittency. Each project must include at least 0.5 MW/2 MWh of battery storage per 1 MW of solar, with charging limited to solar energy. Developers may choose project locations, but the storage system must be installed at the same site as at least one solar unit. Projects will be selected through a tariff-based competitive bidding process and connected to the Inter-State Transmission System. Online bid submissions close on July 22, 2025, with offline submissions due by July 24.
