The last date for submission of bids is July 13, 2026 till 3:00 PM. The techno-commercial bids will be opened on the same day at 3:30 PM.
Design life of the BESS system, including that of the battery, shall be of 25 years (with degraded capacity as per the bidder’s proposal, considering daily single cycle operation) from the date of commissioning. Batteries offered must be rated for a minimum of 10,000 cycles of operation.
Bidders must guarantee a minimum of 98 percent of dispatchable capacity at POI across all 15 years, starting with 100 percent of rated dispatchable capacity in the first year.
Minimum monthly Round Trip Efficiency (RTE) must be 80 percent including auxiliary consumption. Monthly availability must be maintained at 98 percent.
The bidder must have manufactured and supplied batteries of a cumulative capacity of a minimum of 80 MWh for grid-interactive BESS, out of which at least one supply order must be of a minimum 20 MWh capacity. The reference BESS capacity must have been in successful operation for at least six months.
Alternatively, the bidder must have supplied, installed/supervised installation and commissioned/supervised commissioning of grid interactive BESS of cumulative installed capacity of minimum 80 MWh, out of which at least one project must be of minimum 20 MWh capacity. The reference BESS capacity must have been in successful operation for at least six months.
The bidder must be a developer or an EPC company having designed, supplied, erected/supervised erection, and commissioned/supervised commissioning of Solar Photovoltaic (SPV) or Wind-based grid-connected power plant(s) of cumulative installed capacity of 40 MW or higher. Out of this, at least one plant must have been of 10 MW or higher capacity. The reference plant of 10 MW or higher capacity must have been in successful operation for at least six months.
Alternatively, the bidder must have executed in the last 10 years an industrial project either as a developer or as an EPC contractor in the area of power, steel, oil and gas, petrochemical, fertiliser, cement, coal mining, including coal handling plant and or any other process industry, of a value of at least INR 159 crore, in a single project or single work. The same should be in successful operation for at least one year for industrial projects other than RE projects and for at least six months for solar and wind projects.
Additionally, the bidder must have executed at least one electrical sub-station of 33 kV or above voltage level, consisting of equipment such as 33 kV or above voltage level circuit breakers and power transformer, either as a developer or as an EPC Contractor. The same should be in successful operation for at least one year for industrial projects other than RE projects and for at least six months for RE projects, prior to the date of techno-commercial bid opening.
The average annual turnover of the bidder must not be less than INR 159 crore during the preceding three financial years as on the date of the techno-commercial bid opening.
