India: Engie secures solar-plus-600 MWh battery storage project, L&T to build 3 GW pumped storage project

Engie has secured a 200 MW solar project paired with a 100 MW/600 MWh battery energy storage system (BESS) in India. The project was awarded through a competitive bidding process conducted by the Solar Energy Corp. of India (SECI).

This marks Engie’s first hybrid solar-plus-storage project in India. The company will develop the project on a build-own-operate (BOO) basis, supplying power under a 25-year power purchase agreement (PPA) to be signed with SECI.

The latest win follows Engie securing its first standalone BESS project of 280 MW/560 MWh in November. Engie currently has nearly 2 GW of renewable assets in operation and under construction across India.

Amit Jain, CEO and country manager, Engie India, and managing director, Renewables & Batteries India & South-East Asia, said, “In an increasingly unpredictable global energy landscape, enabling firm, clean power isn’t just a technical breakthrough, it’s a strategic imperative. By integrating long-duration storage with large-scale solar, we’re supporting India’s ambition for 24/7 renewable power and stronger grid resilience. This win deepens Engie’s commitment as a long-term partner in building a future-ready, low-carbon energy system that can weather both demand shifts and global disruptions.”

The project will now move into the next phase of development, including detailed engineering, procurement, and regulatory approvals, followed by construction. Engie will work closely with technology partners, suppliers, and relevant authorities to ensure timely and compliant execution.

Meanwhile, Larsen & Toubro (L&T) has announced that its Heavy Civil Infrastructure business vertical has secured an order from Torrent Energy Storage Solutions (earlier known as Torrent PSH 3 and an arm of Torrent Power) for the construction of the 3 GW Saidongar-1 pumped storage project (PSP) in Raigad, Maharashtra. The Saidongar-1 PSP, India’s largest pumped storage project, will comprise ten units of 300 MW each.

The scope of the contract includes the design, engineering, and execution of all civil and hydro-mechanical works associated with the project.

“This order is a testament to L&T’s unmatched capability in delivering complex hydroelectric and pumped storage projects of national importance. With a track record of engineering excellence, timely execution, and world-class safety standards, the Saidongar-1 PSP reinforces L&T’s position as a trusted partner for large-scale, high-capacity pumped storage solutions,” the company stated.

In June last year, Larsen & Toubro also secured an order from JSW Energy for the execution of the Bhavali pumped storage project (PSP) in Maharashtra. The project, strategically located across the Nashik and Thane districts, is designed to have a total installed capacity of 1.5 GW, comprising multiple smaller units.
