Naik noted that major components used in these systems—such as battery cells and battery management systems— are currently based on imported technology.
He also clarified that the Central Electricity Authority (CEA) has not issued any guidelines for standardisation of rates, technology parameters, or performance.
However, CEA has issued draft Central Electricity Authority (Measures relating to Safety and Electric Supply) (First Amendment) Regulations, 2025 for stakeholders’ comments, which include provisions related to safety requirements for BESS, Naik said.
Responding to another query, Naik shared data on the current power generation costs and the estimated costs of electricity from various sources.
He cited the CEA's report on the Weighted Average Rate of Sale of Power for 2023–24, which recorded the all-India weighted average electricity price at INR 4.52 per unit for coal-based power plants, INR 3.27 per unit for hydro, and INR 3.82 per unit for nuclear sources.
The cost of electricity from new power plants varies depending on, inter-alia, the generation source, raw material and fuel costs, and capital investment. The estimated generation cost is INR 5 to 6 per unit for coal-based power, INR 2.50 to 3.00 per unit for solar, INR 3 to 4 per unit for wind, INR 5 to 6 per unit for hydro, and INR 6 to 7 per unit for nuclear.
As of March 31, 2025, India’s total installed capacity from Renewable Energy (RE) resources (including large hydro) stood at 220.10 GW.
In FY 2024–25, the country generated 4,03,643.17 million units (MUs) of electricity from renewable sources, up from 3,59,888.75 MUs in the previous year.
In the current financial year, up to May 2025, RE sources have already generated 73,333.53 MUs of power.
