Tata Power Renewable Energy Limited (TPREL) has entered into a Power Purchase Agreement with Tata Power Mumbai Distribution for an 80 MW Firm and Dispatchable Renewable Energy project, announced on October 2, 2025. The initiative represents a significant step in strengthening India's clean energy infrastructure through advanced renewable technology integration.

Project Specifications and Technology

The 80 MW project will integrate advanced solar, wind, and battery storage systems to enable reliable energy dispatch during peak demand, thereby strengthening grid stability. The facility is designed with a commitment to a 4-hour peak power supply, ensuring at least 90% availability during peak demand hours to support the growing energy needs of Tata Power Mumbai Distribution.

The project is scheduled for completion within 24 months from the agreement date. Upon commissioning, the clean energy generated will be seamlessly integrated into Tata Power's Mumbai distribution network, enabling the delivery of reliable, low-emission electricity to around 8 lakh customers across residential, commercial, and industrial consumers.

Environmental and Energy Impact

The renewable energy facility is expected to generate approximately 315 million units (MUs) of electricity annually. This energy production will result in mitigating over 0.25 million tons of carbon dioxide emissions per year, contributing significantly to environmental sustainability goals. The project will play a pivotal role in helping Tata Power Mumbai Distribution meet its Renewable Purchase Obligation (RPO), as mandated by the State's Regulatory Commission.

Once commissioned, Tata Power Mumbai will meet peak-hour demand with firm and dispatchable renewable energy, thereby addressing critical grid stability requirements during periods of high demand.

Company Portfolio and Market Position

With this addition, TPREL's total renewable utility capacity reaches 11.3 GW, with PPA capacity standing at 9.4 GW. The company currently has 5.7 GW of projects under various stages of implementation, while its operational capacity is 5.6 GW, comprising 4.6 GW of solar and 1 GW of wind capacity. TPREL's solar EPC portfolio encompasses more than 15.7 GWp of ground-mount utility-scale projects and over 3 GW of rooftop and distributed ground-mounted systems.

This collaboration reinforces TPREL's position as a trusted leader in India's renewable energy sector, demonstrating the company's steadfast commitment to sustainability and innovation as it continues to drive forward India's mission of a greener and more resilient energy future.

Strategic Significance

The agreement represents a significant internal collaboration within the Tata Power ecosystem, with TPREL, a subsidiary of The Tata Power Company Limited and a prominent player in India's renewable energy sector, providing clean energy solutions to the Mumbai distribution network. TPREL aims to provide energy access to millions of people nationwide through its integrated green energy solutions.

The Mumbai project exemplifies this commitment by serving approximately 800,000 customers across multiple consumer segments, from residential users to extensive industrial facilities, ensuring broad-based access to clean energy resources.
