India is preparing to launch pilot projects to install battery energy storage systems (BESS) at existing coal-fired power plants, aiming to strengthen grid reliability as solar and wind generation expand rapidly.
According to officials, the initiative will allow coal stations to operate more flexibly by storing excess renewable energy during the day and supplying it back to the grid during peak evening demand. This hybrid approach is expected to ease pressure on conventional power plants, reduce fuel use, and cut emissions while maintaining stability in the power system.
The plan comes as India adds record levels of solar capacity, which often creates surplus generation during daylight hours but leads to sharp evening deficits when solar output declines. Integrating storage with coal plants is seen as a cost-effective way to bridge this gap, while the country continues to scale up renewable projects and standalone battery facilities.
Experts believe these pilots could pave the way for wider adoption of co-located renewable-plus-storage solutions, helping India move toward its clean energy targets without compromising grid security.
The government has already outlined ambitious goals under its renewable energy program, and battery integration at thermal plants may become a key transitional strategy as the nation works toward a low-carbon future.
