Tata Power Renewable Energy Limited (TPREL) has signed a Power Purchase Agreement (PPA) with Tata Power Mumbai Distribution to develop an 80 megawatt (MW) Firm and Dispatchable Renewable Energy (FDRE) project at a capital investment of Rs 12 billion.

An FDRE project combines advanced solar, wind, and battery storage systems to ensure reliable power delivery during peak demand hours, thereby enhancing grid stability and supporting Mumbai’s growing energy needs.

According to an exchange filing by Tata Power, the parent company of TPREL, the project execution period is 24 months. The company estimates that the project will generate about 315 million units (MUs) of renewable electricity annually, helping to offset over 0.25 million tonnes of carbon dioxide emissions every year.

A defining feature of the project is its four-hour peak power supply window, designed to guarantee at least 90 per cent availability during high-demand periods. This initiative will also assist Tata Power Mumbai Distribution in meeting its Renewable Purchase Obligation (RPO) under the mandate of the State Regulatory Commission.

Once commissioned, the clean energy from this project will be integrated into Tata Power’s Mumbai distribution network, supplying low-emission, dependable electricity to around 800,000 residential, commercial, and industrial customers.

With this addition, TPREL’s total renewable utility capacity now stands at 11.3 gigawatts (GW) — including 9.4 GW under PPAs, 5.7 GW in various stages of implementation, and 5.6 GW operational, comprising 4.6 GW of solar and 1 GW of wind energy.
