The Solar Energy Corporation of India Limited (SECI), a public sector body under the Ministry of New & Renewable Energy, has issued the tender for setting up 500 MW/1000–MWh Standalone Battery Energy Storage Systems (BESS). The Central Electricity Authority (CEA)/MoP has recommended that a battery energy storage capacity of 27,000 MW/108,000 MWh (4–hour storage) ought to be part of the installed capacity in 2029–30. As evening power demand is fulfilled by coal plants, having a battery system integrated with a solar power plant will mean that the dependency on coal can be reduced and more renewable energy can be supplied to homes and establishments.
