India’s power grid is getting its own massive ‘backup battery’ and Power Mech Projects is the one building it.
The scoop: the company’s subsidiary, PM Green Private, has secured a ₹3,126 crore order from West Bengal’s power distribution company, WBSEDCL, to set up a large battery storage facility in Goaltore, West Bengal.
The project will have a capacity of 250 MW/1,000 MWh, making it a major addition to the state’s energy infrastructure.
Think of it as a giant power bank for the grid. When there’s extra electricity available, the system stores it. And when demand spikes, it releases that stored power back into the system, helping prevent shortages and keeping supply stable.
PM Green will manage the entire project end-to-end, from design and financing to engineering, procurement, construction, and then long-term operation and maintenance. After that, the company will continue to operate and maintain it for 15 years, making this a long-term, steady-revenue project.
