Tata Power has received a letter of award (LoA) from Solar Energy Corporation of India Ltd (SECI) for the supply of 324 MW power from Tata Power’s 1,000-MW pumped hydro storage project (PSP) at Bhivpuri in Raigad district, Maharashtra.
In a release, Tata Power said that the project has been secured under SECI’s tariff-based global competitive bidding (PSP-I) for supply of 1,500 MW/12,000 MWh of power from pumped hydro storage projects being set up in the country. The project was won through an e-reverse auction. It has 40-year pumped storage purchase agreement and is scheduled for commissioning by 2029.
The project will be developed under the build, own, operate (BOO) model and will provide 8 hours of energy storage, enabling reliable dispatch of electricity during periods of peak demand. It will be connected to the 765/400kV South Kalamb substation in Maharashtra, which is part of the interstate transmission system (ISTS) grid.
The SECI’s award had further strengthened Tata Power’s position in long-duration energy storage, a segment central to integrating India’s fast-growing solar and wind capacity into the grid by converting surplus daytime generation into firm, dispatchable, round-the-clock power.
The awarded capacity sits at the 1,000-MW Bhivpuri PSP, one of two large pumped storage developments the company is progressing in the Western Ghats alongside the 1,800-MW Shirwata PSP, with a combined pipeline of 2,800 MW.
Green portfolio
Tata Power’s clean and green portfolio now stands at 17.5 GW, including a 9.6 GW pipeline, of which 2.8 GW is pumped storage. As India’s peak demand climbs and the share of variable renewables rises, long-duration storage is becoming the backbone of grid flexibility and credible round-the-clock green power, an area where Tata Power’s long-standing presence and favourable hydro-geography in the Western Ghats give it a distinct advantage, the release added.
