India's energy storage pipeline is expanding rapidly, with nearly 47 GW of battery energy storage system (BESS) capacity and 23 GW of pumped storage projects at various stages as of June 30, 2026, according to data presented in Parliament by Minister of State for Power Shripad Yesso Naik.

Of the BESS projects, 16 GW is under construction, 12 GW has been awarded, and 19 GW is in the tendering phase. For pumped storage, 16 GW is being built and 7 GW has received concurrence but construction has not yet started. The National Electricity Plan (Generation) projects a requirement of 47 GW of BESS and 27 GW of pumped storage by 2031-32, meaning the current BESS pipeline already matches the target, while pumped storage is close.

Naik, in a written reply to the Rajya Sabha on July 28, 2026, said that achieving these targets will require investments of about Rs 4.8 lakh crore in energy storage by 2031-32, with Rs 3.5 lakh crore allocated for BESS and Rs 1.3 lakh crore for pumped storage.

On the renewable generation side, Andhra Pradesh added 3,865.63 MW of renewable energy capacity in FY26 (2025-26), nearly four times the 1,085.15 MW added in FY25. The state's previous annual additions were far lower: 125.42 MW in 2021-22, 148.62 MW in 2022-23, 59.15 MW in 2023-24, and 1,085.15 MW in 2024-25, according to an official press release on July 27, 2026.

India is also building conventional power capacity. Since April 2023, 21 GW of thermal capacity has been commissioned, 48 GW (including 4.8 GW of stressed projects) is under construction, and contracts have been awarded for another 16 GW of coal or lignite plants. On the renewable side, 148 GW is under construction and 48 GW is at the planning stage, targeted for completion by 2029-30.

The country's total installed power generation capacity is projected to reach 874 GW by 2031-32, driven by the simultaneous expansion of renewable and thermal generation along with the storage infrastructure needed to integrate them.
