Larsen & Toubro’s (L&T) Heavy Civil Infrastructure (HCI) business vertical has secured a major order from Torrent Energy Storage Solutions Pvt Ltd (formerly Torrent PSH 3 Pvt Ltd) to construct the 3,000 MW Saidongar-1 Pumped Storage Project (PSP) in Raigad, Maharashtra. The project represents a significant step in strengthening India’s grid reliability and energy security while supporting the country’s renewable energy and decarbonisation goals.
Project Overview and Scope
The Saidongar-1 PSP will consist of ten units of 300 MW each, totaling 3,000 MW. L&T’s scope includes design, engineering, and execution of all civil and hydro-mechanical works, making it one of the largest pumped storage contracts undertaken in the region. Pumped storage projects like Saidongar-1 are crucial for balancing grid demand, storing surplus energy during low demand periods, and releasing it during peak consumption, thereby providing flexible and reliable power to Maharashtra and surrounding states.
Timeline and Approvals
The project received environmental clearance in January 2025. Given its scale and regulatory requirements, completion is expected within 36 to 60 months. Once operational, the PSP will enhance grid stability, provide backup power, and support long-term decarbonisation efforts in line with India’s energy transition objectives.
Previous Projects and Industry Context
L&T HCI has prior experience with pumped storage in Maharashtra, including the 1,500 MW Bhavali PSP executed in collaboration with JSW Energy across Nashik and Thane districts. Torrent Power Ltd has also previously secured 2,000 MW energy storage capacity orders from the Maharashtra State Electricity Distribution Company Ltd (MSEDCL), demonstrating the growing importance of pumped storage in the state’s renewable energy roadmap.
Strategic Significance
The Saidongar-1 PSP reinforces L&T’s leadership in heavy civil and hydro-mechanical infrastructure while contributing to India’s push for energy security, grid flexibility, and domestic renewable energy capacity. The project is expected to generate significant employment opportunities and stimulate ancillary industries, including construction, machinery, and logistics, further boosting Maharashtra’s economic growth.
