Welspun New Energy has announced that it has signed a Power Purchase Agreement (PPA) with Solar Energy Corporation of India (SECI) for a 200 MW solar project integrated with 400 MWh of battery energy storage system (BESS). This marks the company’s first PPA incorporating energy storage.

The company secured the capacity in SECI’s auction for setting up 2,000 MW ISTS-connected solar PV projects with 1,000 MW/4,000 MWh energy storage systems (ESS) held in October 2025, at a tariff of INR 2.86/kWh. With this addition, the company’s total contracted capacity has reached 1,600 MWp.

As per the tender specifications, Welspun must develop a transmission network up to the interconnection point at 220 kV or above, including land identification, project installation, ownership, and securing all necessary connectivity and approvals with the ISTS network.

Each project must include an energy storage system with a minimum capacity of 0.5 MW/2 MWh for every 1 MW of installed capacity, either owned by the developer or arranged through a third-party provider. The system must maintain a minimum capacity utilisation factor (CUF) between 19 percent and 30 percent.

Only solar cells and modules listed in the Approved List of Models and Manufacturers (ALMM) should be used in the project.
