Bidders may also qualify under the first route if they have erected, tested, and commissioned at least two air-insulated switchgear or gas-insulated switchgear circuit breaker bays of 33 kV or above in a substation or switchyard.

Under the second route, bidders must have manufactured and supplied at least 50 MWh of batteries of the offered technology during the last seven years, of which at least 10 MWh must be in satisfactory operation as of the original bid submission deadline. They may also qualify through a technical collaboration or a manufacturing license agreement with a battery manufacturer that meets these requirements.

In March this year, POWERGRID invited bids to set up a 100 MW/200 MWh BESS at the 220 kV Bhatinda substation in Punjab.

In the same month, the company invited bids to set up a 50 MW/100 MWh battery energy storage system (BESS) project in Patiala, Punjab.
