L&T to Execute India’s Largest 3,000 MW Pumped Storage Project in Maharashtra

Larsen & Toubro has secured a major infrastructure contract for the construction of India’s largest pumped storage power project, with a total capacity of 3,000 MW, in Raigad district of Maharashtra. The project, awarded by Torrent Energy Storage Solutions Pvt Ltd, involves the development of the Saidongar-1 Pumped Storage Project, designed with ten generating units of 300 MW each.

Under the contract, L&T will be responsible for comprehensive civil and hydro-mechanical works, including detailed design, engineering, and on-ground execution. Once operational, the project is expected to play a key role in improving grid stability and strengthening energy reliability across the state.

Pumped storage facilities are increasingly seen as critical infrastructure for balancing renewable energy generation, as they allow surplus electricity to be stored and deployed during peak demand periods. The Saidongar-1 project aligns with India’s broader efforts to enhance energy security while supporting long-term clean energy and decarbonisation objectives.
