Bidders should have manufactured and supplied batteries for 40 MW or higher grid-connected BESS, of which at least one system should have a 10 MW capacity or higher. The reference BESS must have operated for at least six months before the bid opening date.

Bidders who are integrators of grid-connected BESS projects meeting the above criteria can also submit bids.

Indian bidders should have a technical collaboration agreement, a manufacturing license, or a joint venture company with a battery manufacturer. They must furnish a technical collaboration agreement with the battery manufacturer. This agreement should be ongoing and valid until the operation and maintenance period ends.

Bidders should have executed an industrial project in power, steel, oil and gas, petrochemical, fertilizer, cement, coal mining, or any other process industry in the last ten years. The value of the projects must be ₹1.65 billion (~$19.75 million) or more in a single project. This project must be in successful operation for at least one year before the bid opening date.

They should have executed at least one electrical substation of 33 kV or above voltage level, consisting of equipment such as 33 kV or above voltage level circuit breakers and power transformers. This substation must be in successful operation for at least one year before the bid opening date.

Their net worth on the last day of the last financial year should not be less than 100%  of their paid-up share capital.

In December, Jayram Industries India secured the contract from NTPC Renewable Energy to commission a 250 kW/1,200 kWh BESS supporting solar power projects at the Khavda Renewable Energy Park in Gujarat.

Earlier, NTPC Renewable Energy had issued a tender for the design, engineering, manufacturing, supply, installation, and commissioning of a 250 MW/500 MWh grid-connected standalone BESS near Fatehgarh-III ISTS substation in Rajasthan.
