Tata Power’s board has approved an investment of ₹11,871 crore in a proposed 1,800 MW pumped-storage project at Shirwata in Maharashtra. The company’s 11 November exchange disclosure says the project is expected to be implemented within 51 months and funded through a proposed 75% debt and 25% equity mix.
What the board approved
The approval covers the Shirwata pumped-storage project, which the company describes as a capacity addition to its existing portfolio of 16.9 GW. The announced ₹11,871 crore is the project investment estimate; it is not evidence that the money has already been spent. The filing gives a 51-month implementation period but does not specify a construction start date or detailed financing terms.
Pumped-storage plants use electricity to move water to an upper reservoir and later release it through turbines to generate power. Tata Power says the project is intended to support round-the-clock renewable energy applications, shift energy across time periods and help decarbonise hard-to-abate industries.
Part of a wider storage build-out
The Shirwata proposal is separate from Tata Power’s 1,000 MW Bhivpuri pumped-storage project, which the company reported as progressing in its Q2 FY27 update. The company’s investor presentation also lists preliminary activity for Shirwata. These disclosures indicate a broader storage pipeline, but do not establish that either project is operational.
Grid-scale storage can help balance variable renewable generation by storing energy when it is available and releasing it when demand or supply conditions require. The project’s eventual contribution will depend on construction, approvals, financing, operating arrangements and the way the plant is integrated with the grid.
Funding and execution remain key milestones
The proposed 75:25 debt-equity structure means debt is expected to fund most of the stated project investment. Actual funding, project costs, timelines and returns can evolve during implementation. The company filing does not set out project-specific borrowing terms, tariff arrangements or a detailed construction schedule.
The 51-month implementation window makes execution a multi-year undertaking. Permits, engineering and construction progress, financing availability and project economics will be important to track as the development advances. The board approval is a material step, while completion and commercial operation remain future milestones.
