GUVNL Awards 335 MW/670 MWh BESS Projects to Advait, Equentia, Sun Drop

Gujarat Urja Vikas Nigam Limited (GUVNL) has successfully completed the auction for Standalone Battery Energy Storage Systems (BESS) Phase-VIII in Gujarat. The auction covers a total capacity of 335 MW with 670 MWh of energy storage, marking another significant milestone in strengthening India’s renewable energy ecosystem and ensuring reliable clean power supply.

There was a lot of interest from renewable energy developers in the tender, which was held through a competitive bidding process based on tariffs. The discovered tariffs ranged from “₹2.1 lakh per MW per month” to “₹2.12 lakh per MW per month,” which shows that the market is becoming more confident in battery storage as a way to handle peak demand and make the grid more stable.
