Under this RfS, the BESSD will be required to set up a Battery Energy Storage System (BESS), with the primary objective of making the energy storage facility available to the NVVN for charging/discharging of the BESS, on an ‘on demand’ basis.
Setting up of the BESS and interconnection of the BESS with the STU network including the construction of the Bay will be under the scope of the BESSD.
The VGF support has been earmarked for a cumulative BESS capacity of 2,000 MWh (allocated capacity to NVVN), to be awarded through several tranches. “Under this RfS, the VGF amount eligible for each developer will be limited to the amount calculated at INR 27 lakh/MWh or 30 percent of the capital cost of the project capacity awarded whichever is lower,” mentioned the RfS document.
Bidders need to pay INR 22,500 as a cost of the RfS document. Further, they need to submit INR 15 lakh (plus GST) as a document processing fee. Additionally, they need to furnish INR 6.82 lakh/MW as an earnest money deposit (EMD). Selected bidders need to submit a Performance Bank Guarantee (PBG) for a value of INR 17.05 lakh/MW prior to signing of BESPA.
The last date for submission of bids is March 31, 2025. The techno-commercial bids will be opened on April 1, 2025.
The minimum bid size must be 100 MWh i.e. 50 MW x 2 hours. Each location specified in the RfS will have a maximum capacity of 125 MW/250 MWh. Bidders can quote in increments of 25 MW/50 MWh.
“A Bidder, including its Parent, Affiliate or Ultimate Parent or any Group Company shall submit a single bid offering a project capacity of either one project or multiple projects out of the total capacity of 250 MW/500 MWh in the prescribed formats,” it said.
For each 125 MW/250 MWh BESS project, only 17,500 sq. m. (1.75 Hectares) of land will be allotted to the BESSD.
This RfS is technology agnostic on the nature of the battery storage system being opted by the BESSD.
As for financial eligibility, the net worth of the bidder should be equal to or greater than INR 68.20 lakh/MW of the quoted capacity in MW (i.e. INR 34.10 lakh/MWh of the MWh capacity), as on the last day of the preceding financial year on the date of techno-commercial bid opening.
Further, the company must possess a minimum annual turnover of INR 2.27 crore/MW of the quoted capacity in MW, in the financial year as on the date of techno-commercial bid opening.
