Power Mech Projects Limited (“PMPL” or the “Company”) one of the leading industrial engineering, construction and services companies in the power and infrastructure sectors, has announced that its wholly owned subsidiary, PM Green Private Limited as a lead member has secured a contract for 1 GWh Battery Energy Storage System (BESS) from West Bengal State Electricity Distribution Company Limited (WBSEDCL).
As part of PMPL renewable energy strategy, PM Green participated in the tender from the Department of Power (DoP), Government of West Bengal, and has been awarded the contract for setting up a 250 MW / 1,000 MWh Battery Energy Storage System (BESS). The project has been structured as a Build, Own, Operate (BOO) model, with a 100% off-take guarantee from WBSEDCL.
The scope of work includes design, finance, engineering, procurement, construction, operation, and maintenance of the BESS facility at the Goaltore Substation. There is an additional greenshoe option with additional capacity of 250MW / 1,000 MWh to be established at Durgapur Project Limited Campus, Durgapur.
Key Features of the Contract:
Revenue Generation : ₹ 3,126 Crores (Including Greenshoe Capacity)
Project Capacity : 250 MW/ 1000 MWh at Goaltore SS, Paschim Midnapore
Green Shoe Capacity : 250 MW/ 1000 MWh at Durgapur Project Ltd Campus, Durgapur
Construction Period : 18 months from signing the Battery Energy Storage Purchase Agreement (BESPA)
Contract Duration : 15 years with provision for extension upto 5 years from Schedule Commissioning Date
Commenting on the BESS Contract, Mr. Sajja Kishore Babu, Chairman and Managing Director, said, “As India crosses the monumental threshold where renewable energy exceeds 50% of our installed capacity, green energy is the next great challenge. We need advanced peak-shaving solutions to balance the grid and ensure that the transition to “Green” does not compromise “Reliable”. This BESS project is far more than a commercial win, it is the first concrete step in our vision to provide that equilibrium. While PM Green is taking its foundational steps today, it carries thedecades of “Execution Power” and the ‘vast engineering legacy’ of Power Mech. Winning a project of this scale as our debut in energy storage solutions is a powerful testimony to our capabilities to handle large and complex projects. We are building a future where clean energy is available round-the-clock, reliable, and accessible. This project demonstrates our capability in the power sector as we expand into a new energy vertical, and it serves as a bold preview of what we aim to achieve in the years ahead.”
