Tata Power Strengthens Mumbai's Green Energy Infrastructure with Multiple Renewable Power Agreements

Tata Power has reportedly signed a series of long-term renewable energy power purchase agreements over the past fortnight to enhance clean energy supply to Mumbai and manage the increasing peak electricity demand during the current hot and humid weather conditions, according to company sources.

The utility provider, which caters to approximately 800,000 consumers across the island city and suburban areas of Mumbai's real estate landscape, recorded a peak power demand of 1,000 MW on October 17, with similar consumption levels continuing in subsequent days.

Strategic Renewable Energy Procurement

To address this demand sustainably, the company has secured Firm and Dispatchable Renewable Energy commitments from several clean energy developers through structured power purchase agreements spanning multiple decades.

Acme Solar Holdings Partnership

Tata Power has entered into a 25-year power purchase agreement with Acme Solar Holdings for 50 MW of Firm and Dispatchable Renewable Energy at a tariff of ₹4.43 per unit. The project will utilize solar power integrated with Battery Energy Storage Systems, along with an additional commitment to supply four hours of peak-hour power monthly with 90% availability assurance.

Juniper Green Energy Collaboration

Through Juniper Green Sigma Eight, the subsidiary of Juniper Green Energy Limited, Tata Power has secured 70 MW of FDRE capacity. The Maharashtra-based facility will feature hybrid solar systems with 180 MWp capacity and wind power infrastructure, complemented by a 280 MWh Battery Energy Storage System to ensure consistent power delivery.

Tata Power Renewables Internal Agreement

In an internal arrangement, Tata Power has contracted 80 MW of FDRE from its own subsidiary, Tata Power Renewables. This facility is expected to generate 315 million units annually and is projected to reduce carbon dioxide emissions by over 0.25 million tons per year through advanced integration of solar, wind, and battery storage technologies.

Firm and Dispatchable Renewable Energy Model

These agreements fall under the Firm and Dispatchable Renewable Energy framework, which combines renewable power sources with energy storage infrastructure to ensure reliable electricity supply during peak consumption hours—a critical requirement for metropolitan centers like Mumbai's residential and commercial sectors. The model guarantees availability-based power delivery, addressing the intermittency challenges typically associated with solar and wind energy generation.

A senior official from Tata Power stated that these power purchase agreements would strengthen grid stability and facilitate the decarbonization of power supply for residents across Mumbai's growing urban areas, while offering competitive and stable tariff structures over extended durations.

Addressing Rising Urban Energy Demand

The financial capital's increasing temperatures and elevated residential and commercial cooling requirements have driven up electricity consumption, prompting utilities to strengthen their peak-hour supply capabilities. By investing in hybrid renewable energy projects integrated with storage solutions, Tata Power is aligning its operations with both consumer reliability expectations and the nation's clean energy transition objectives.

These power purchase agreements also support the company's broader strategy to expand its green energy portfolio, enhance energy security for urban distribution networks, and contribute to carbon neutrality targets in the sustainable power infrastructure sector.

The initiative comes as Mumbai Metropolitan Region continues to witness infrastructure development and increasing energy demands from both residential and commercial segments.
