The electricity board of the Indian state of Gujarat is tendering for 500MW/1,000MWh of standalone battery energy storage systems (BESS).
Electricity market regulation board Gujarat Urja Vikas Nigam (GUVNL) issued a Request for Selection (RfS) document for what it described as pilot projects. GUVNL is also the holding company for the state-owned generation, transmission and distribution companies (discoms).
GUVNL said the projects would be utilised on an ‘on-demand’ basis according to the requirements of the discoms.
Though not spelt out, it appears they need to have a discharge duration of two hours, which increases the ability to provide load shifting services (versus ancillary services where duration is less important than nameplate MW power). The tender requires them to be available for two full operational cycles (charge and discharge) per day with an availability of at least 95%.
GUVNL will enter into a Battery Energy Storage Purchase Agreement (BESPA) with the successful bidders, who will be required to set up the projects on a build-own-operate model.
