Larsen & Toubro’s Heavy Civil Infrastructure division has won a significant contract from Torrent Energy Storage Solutions Pvt. Ltd. to develop the 3,000 MW Saidongar-1 Pumped Storage Project in Raigad, Maharashtra.
Earlier known as Torrent PSH 3 Pvt. Ltd., the company has awarded L&T the responsibility of executing what is poised to become India’s largest pumped storage facility. The project will host ten generating units of 300 MW each, marking a milestone for the country’s energy storage and hydro infrastructure sector.
Extensive project scope
Under the contract, L&T will handle the design, engineering, and execution of all civil and hydromechanical components of the project. This includes the construction of underground caverns, water conductor systems, power caverns, and associated structures that are essential for large pumped storage operations.
Leveraging its strong credentials in hydropower and pumped storage execution, L&T will be responsible for delivering the project to rigorous standards of safety, quality, and timelines.
Boost to energy storage and grid stability
The Saidongar-1 pumped storage project is expected to strengthen grid resilience and power availability in Maharashtra and adjoining regions. As India accelerates the adoption of renewable energy, pumped storage systems play a critical balancing role by:
- storing excess power generated during low-demand periods
- supplying electricity during peak load hours
- providing rapid grid balancing support
This capability makes pumped storage a key enabler for integrating large-scale solar and wind energy.
Strengthening L&T’s leadership position
The latest order further cements L&T’s reputation as a leading player in large hydro and pumped storage infrastructure. The company’s track record in delivering complex, high-capacity projects and its emphasis on world-class engineering practices continue to drive major contract wins in the energy infrastructure segment.
Contribution to clean-energy transition
Projects such as Saidongar-1 are instrumental in India’s journey toward lower-carbon power systems. By enabling efficient renewable energy utilisation and reducing reliance on conventional peaking power from fossil fuels, pumped storage solutions support long-term decarbonisation targets while ensuring reliability.
Summary
The Saidongar-1 pumped storage project in Raigad, Maharashtra — awarded to L&T’s Heavy Civil Infrastructure division by Torrent Energy Storage Solutions — will be India’s largest 3,000 MW pumped storage facility with ten 300 MW units. L&T will execute all civil and hydromechanical works, including complex underground and waterway systems. The project is expected to enhance grid stability, support renewable energy integration, strengthen L&T’s leadership in hydro infrastructure, and contribute to India’s clean-energy transition.
