Punjab State Power Corporation (PSPCL) has invited bids to set up 500 MW/1,000 MWh battery energy storage systems in Mohali and Jalandhar.

The last date to submit bids is April 10, 2026. Bids will be opened on April 16.

Bidders must submit ₹471,000 (~$5,118)/MW as an earnest money deposit. Bidders must also furnish a performance bank guarantee of ₹1.17 million (~$12,713)/MW.

The minimum bid size should be 100 MWh, i.e., 50 MW x 2 hours.

The projects must be commissioned within 18 months from the signing of the battery energy storage purchase agreement.

Only commercially established and operational technologies should be used for the projects to minimize technology risk and achieve timely commissioning.

The bidders’ net worth should be at least ₹7 million (~$76,065)/MW of the cumulative contracted capacity, as on the last date of the previous financial year.

Their annual turnover should be at least ₹7 million (~$76,065)/MW as on the last day of the previous financial year.

PSPCL will provide 10 acres of land on lease to the developers at an annual lease charge of ₹1 (~$0.011) per acre. Land allocation for the projects will be under the scope of PSPCL.

The project will not be eligible for viability gap funding.

The responsibility for obtaining state transmission utility connectivity will lie with the developer.

The cost of infrastructure construction from the project up to and including the interconnection point, including, but not limited to, the transmission line, the construction of a new bay, busbar extension and augmentation, maintenance, and all costs up to the delivery point, will be borne by the developer.

The noise level of the battery storage system should be kept below 80 decibels, since residential colonies may be developed on the land adjacent to the sites in the future.

The developer should guarantee a minimum monthly system availability of 95%. The developer will have to pay liquidated damages for any shortfall at the rate of two times the storage tariff for the capacity not made available.

In January this year, PSPCL invited bids to set up 500 MW/1,000 MWh standalone battery energy storage systems.

Earlier, PSPCL issued a request for selection to set up 250 MW/500 MWh standalone battery storage systems in Bhatinda, Punjab.
