Tata Power has approved an investment of ₹11,871 crore for the 1,800 MW Shirwata pumped storage project in Maharashtra, marking a major expansion of the utility’s energy-storage portfolio as demand grows for round-the-clock renewable power.
The company informed the stock exchanges that its board had cleared the capital commitment for the Shirwata Pumped Storage Hydro Project. The project is intended to support renewable-energy round-the-clock applications by shifting electricity across periods of generation and demand.
Pumped storage hydropower uses two water reservoirs at different elevations. Electricity is used to move water to the higher reservoir when power is available, while the stored water is released through turbines to generate electricity when demand rises. This allows intermittent renewable generation to be balanced over longer periods than conventional short-duration storage systems.
Tata Power said the Shirwata project would help enable energy shifting and support the decarbonisation of hard-to-abate industries. The company did not disclose a commissioning timeline, construction schedule or details of the project’s financing in the information provided.
The approval comes as Tata Power advances another pumped storage project in Maharashtra. Construction at its Bhivpuri pumped storage project is progressing on schedule, the company said, without providing further details on its current construction status or expected commissioning date.
The company said the Shirwata investment reinforces its focus on building long-duration energy storage capacity to meet India’s changing power requirements. Storage projects are increasingly being developed alongside renewable-energy capacity to address the mismatch between when solar and wind power is generated and when electricity is consumed.
Tata Power’s overall existing capacity stands at 16.9 GW, according to the company. Its latest investment announcement was made alongside its financial results for the second quarter of financial year 2027.
The company reported consolidated profit after tax of ₹1,652 crore for the quarter, a 33% year-on-year increase. Revenue rose 26% year on year to ₹19,886 crore, while EBITDA increased 5% to ₹4,245 crore. Profit after tax for the first half of FY27 stood at ₹3,053 crore, up 22% year on year.
The next publicly stated step is the implementation of the Shirwata project following the board’s approval of its capital commitment. Tata Power has not announced a project completion date in the information supplied.
