Gujarat Urja Vikas Nigam Ltd. (GUVNL) has floated a tender for setting up 2,000 MW/4,000 MWh standalone battery energy storage systems in Gujarat under tariff-based competitive bidding with viability gap funding (VGF) supported through PSDF (Phase-VII). The projects will be set up under a build, own and operate (BOO) model.

The projects must be located in the vicinity of 12 identified substations of the STU network in Gujarat. Land must be identified by bidders themselves to interconnect BESS with the listed substations.

The projects will be eligible for support under the new VGF Scheme, in which the amount eligible for each developer will be limited to INR 18 lakh/MWh.

Bidders need to pay INR 29,500 as a tender document fee. Further, they need to deposit INR 15 lakh (plus GST) as a document processing fee. They also need to furnish INR 5 lakh/MW as an earnest money deposit (EMD). Selected bidders need to deposit INR 12.5 lakh/MW as a performance bank guarantee (PBG) prior to signing of BESPA.

The last date for submission of bids is September 11, 2025. The techno-commercial bids will be opened on September 17, 2025.

The minimum bid size must be 100 MWh, i.e. 50 MW x 2 hours and in multiples of 50 MW/100 MWh.

The BESS developer will be required to set up a BESS, with the primary objective of making the energy storage facility available to GUVNL for charging/discharging of the BESS, on an ‘on-demand’ basis. The BESSD shall make the BESS available for 2 operational cycles per day, i.e. 2 complete charge-discharge cycles per day.

Setting up of the BESS and interconnection of the BESS with the State Transmission Network will be under the scope of the BESSD.

The BESS must be charged by drawing power from GETCO and injecting power into the GETCO network. GUVNL will provide the required power for charging BESS, considering the minimum system efficiency under the agreement.

The BESSD must guarantee a minimum system availability of 95 percent on an annual basis.

The bidders must have commissioned 1 MW of conventional or renewable energy projects to qualify for bidding 1 MW/2 MWh capacity. Alternatively, they must have commissioned standalone or co-located BESS projects with a minimum capacity of 10 MWh.

As for financial eligibility, the net worth of the bidder must be at least INR 74 lakh/MW of the quoted capacity (in MW), as on the last date of the previous Financial Year, i.e. FY 2024-25 or as on the day at least 7 days prior to the bid submission deadline.
