The Tata Power Company Limited has approved an investment of ₹11,871 crore in a 1,800 MW Pumped Storage Project (PSP) at Shirwata in Maharashtra. The company’s Board of Directors approved the investment at its meeting held on November 11, 2026.
The proposed project is expected to add 1,800 MW of pumped storage capacity to Tata Power’s existing power generation portfolio. The company currently has an overall installed capacity of 16.9 GW. The project is expected to be completed within 51 months.
Investment and Funding Structure
Tata Power has estimated the total investment requirement for the Shirwata Pumped Storage Project at ₹11,871 crore. The project will be financed through a combination of debt and equity, with debt accounting for 75% of the funding and equity contributing the remaining 25%.
Based on the proposed funding structure, approximately ₹8,903.25 crore will be financed through debt, while the remaining ₹2,967.75 crore will be funded through equity.
Role in Renewable Energy Integration
The Shirwata Pumped Storage Project is expected to support Tata Power’s renewable energy integration strategy by facilitating Renewable Energy Round the Clock (RE-RTC) applications.
Pumped storage hydropower projects store energy by pumping water to an elevated reservoir when electricity demand is relatively low and releasing it through turbines to generate electricity when demand increases. This enables energy shifting and helps address the intermittent nature of renewable energy sources such as solar and wind power.
According to the company’s regulatory filing, the project is also expected to contribute to the decarbonisation of hard-to-abate industries by supporting a more consistent supply of renewable electricity.
The proposed investment marks another addition to Tata Power’s energy storage infrastructure and is aimed at supporting the integration of renewable energy into the power grid.
