Larsen and Toubro Limited (L&T) has secured a large contract from Torrent Energy Storage Solutions Private Limited for the construction of the 3,000 MW Saidongar-1 Pumped Storage Project (PSP) in Raigad, Maharashtra. The project is set to become the largest pumped storage facility in India.
The order has been awarded to L&T’s Heavy Civil Infrastructure business vertical. The scope of work includes the design, engineering, and execution of all civil and hydro mechanical components of the project. The PSP will comprise ten units, each with an installed capacity of 300 MW.
In a press release dated January 14, 2026, L&T said the project is expected to strengthen grid reliability and improve energy security for Maharashtra and the surrounding region. The company also highlighted its experience in executing complex hydroelectric and pumped storage projects, supported by established engineering and safety practices.
Pumped storage projects store surplus electricity during periods of low demand and generate power during peak demand, supporting grid stability and decarbonisation efforts. L&T has classified the order as “Large,” which under its internal classification framework corresponds to a contract value ranging from Rs 2,500 crore to Rs 5,000 crore.
In October 2025, the Expert Appraisal Committee (EAC) under the Ministry of Environment, Forest and Climate Change (MoEFCC) recommended Environmental Clearance for a 3,000 MW pumped storage project titled “Saidongar 1 – Karjat Pumped Storage Project” in Raigad, Maharashtra. The proposal was submitted by Torrent PSH 3 Private Limited, a group entity of Torrent. According to the official EAC minutes, the project is planned over 377 hectares and involves two reservoirs with a combined live storage of about 44.8 million cubic metres. The approved configuration provides for an installed capacity of 3,000 MW through 11 generating units comprising 9 units of 300 MW and 2 units of 150 MW. The project involves the construction of two reservoirs with a combined gross storage of about 44.83 million cubic metres.
