State utility Rajasthan Vidyut Utpadan Nigam Ltd (RVUNL) is tendering for 500 MW/1 GWh of standalone battery energy storage systems (BESS) and may allot double that capacity, given sufficient demand.
RVUNL has opened a tender for 500 MW/1 GWh of standalone BESS in Rajasthan. The BESS must support two cycles of complete charging and discharging daily.
Selected bidders will develop state transmission system connected projects on a build, own, and operate basis at RVUNL power stations. RVUNL, which will sign a battery energy storage purchase agreement with the successful bidders, has the option of allotting a further 500 MW/1 GWh.
Successful bidders will be eligible for central government-sourced viability gap funding of either 30% of their BESS capital cost or INR 2.7 million ($32,000) per megawatt-hour of energy storage capacity, whichever is lower.
Minimum bid size in the tender will be 125 MW/250 MWh and the project sites will be identified by the utility, with 17,500 m2 allotted for each 125 MW/250 MWh of BESS capacity.
Projects must be completed within 18 months of contracts being awarded.
