Heavy Civil Infrastructure, a subsidiary of Larsen and Toubro (L&T), has secured an order from Torrent Energy Storage Solutions, an arm of Torrent Power, for the construction of the 3,000 MW Saidongar-1 Pumped Storage Project in the Raigad district of Maharashtra.

The project will comprise ten units of 300 MW each.

The scope of work includes the design, engineering, and execution of all civil works and hydro-mechanical works associated with the project. Once completed, the project is expected to enhance grid reliability and energy security for Maharashtra and support peak power management through energy storage and release during high-demand periods.

L&T’s renewables business operates as an engineering, procurement, and construction service provider for large-scale solar projects, battery energy storage systems, microgrids, and hybrid renewable projects.

L&T secured new solar orders of 2.5 GW in the UAE, 1.2 GW in the CIS region, 3.5 GW in Saudi Arabia, 442 MWp in Africa, and 0.7 GW in India, along with 156 MW of floating solar projects in India during the financial year 2025.

In battery energy storage, new orders included 10 GWh in the UAE, 1 GWh in the CIS region, 1.26 GWh in Africa, and 45 MWh in India. Commissioned projects include 1 GW of solar capacity in India, 1.1 GW in the UAE, and 0.8 GW in Saudi Arabia.

On a cumulative basis, L&T has installed 25.2 GW of solar capacity, including 444 MW of floating solar, deployed 12.8 GWh of battery energy storage systems, and executed 1.67 GW of wind balance-of-plant works.

The company has also established a new wind vertical to address rising demand and is integrating solar with battery storage to deliver round-the-clock renewable power. It has set up a liquid-cooling container-integration facility for battery storage in Kancheepuram, with a capacity of 1.2 GWh per annum.

Renewables and green businesses contribute 53% of L&T’s revenue. The company sources 15% of its electricity from renewable energy.

In October 2025, L&T, in partnership with Hitachi Energy, was nominated by transmission system operator TenneT to deliver high-voltage direct current converter stations for offshore wind projects across the German and Dutch sectors of the North Sea.

In August 2025, L&T Renewables won Bihar State Power Generation Company’s auction for the engineering, procurement, and construction of a 116 MW solar power project integrated with a 241 MWh battery energy storage system in Kajra, Lakhisarai district, Bihar.
