With this, RVUNL becomes the first Genco to issue a tender under the second tranche of the Viability Gap Funding (VGF) scheme.
The BESS will be connected to STU network near 6 identified substations in Rajasthan. It includes 3 substations in Bikaner with a capacity of 200 MW/400 MWh for 2 projects and a capacity of 100 MW/200 MWh for the third one. The other three substations are in Jodhpur with a project capacity of 100 MW/200 MWh for two projects and 300 MW/600 MWh for the third one.
Bidders need to pay INR 5 lakh (plus GST) as a tender document fee and another INR 2,500 (plus GST) as a tender processing fee. Further, they need to furnish INR 2.10 lakh/MWh as an earnest money deposit (EMD). Selected bidders need to submit a performance bank guarantee (PBG) of INR 5.20 lakh/MWh, prior to signing BESPA.
The last date for submission of bids is August 4, 2025. The techno-commercial bids will be opened on August 5, 2025.
The minimum bid size will be 100 MWh (50 MW x 2 hours) and the maximum capacity a single bidder can bid for is 250 MW/500 MWh.
Land, if available, shall be provided by RVUNL on actual charges. “Alternatively, the BESS developers may also arrange their own land, in such case, RVUNL shall extend the necessary support for its identification and acquisition,” noted the tender.
The project must be designed for interconnection with the STU network in accordance with the prevailing RERC regulations and will be entirely in the scope of BESSD.
The BESSD shall make the BESS available for 2 operational cycles per day, i.e. 2 complete charge-discharge cycles per day.
The BESSD must install, operate and maintain the BESS to offer the facility to RVUNL to charge and to discharge the BESS on an “on-demand” basis. The BESSD must guarantee a minimum system availability of 95 percent on a monthly basis.
The tender proposes to promote only commercially established and operational technologies to minimise the technology risk and to achieve timely commissioning of the projects.
The net worth of the bidder must be equal to or greater than INR 20 lakh/ MWh of the quoted capacity in MWh, as on the last day of the preceding financial year on the date of the techno-commercial bid opening.
