State-owned utility Gujarat Urja Vikas Nigam Limited (GUVNL) has opened a 500MW tender for renewable energy paired with energy storage systems (ESS) to bring electricity to remote, off-grid villages in Gujarat, India.
GUVNL is seeking to enter power purchase agreements (PPAs) for up to 500MW of grid-connected renewable energy and ESS capable of delivering the peak power requirements of local distribution companies (discoms).

The 25-year PPAs will help GUVNL to meet its renewable power purchase obligations (RPPO) as well as the future needs of discoms.
Projects proposed can be either solar PV, wind or a combination of both, paired with energy storage. However, certain minimum capacity requirements apply based on the chosen combination: for instance, plants with wind and a co-located storage system without solar must be 25MW or more.
Meanwhile other configurations have a 50MW minimum requirement, and other stipulations apply such that if a wind-solar and battery hybrid is proposed, the smaller of the two renewable energy systems must be sized to at least 33% of the total contracted capacity.
Peak time and off-peak time tariffs will be paid to winning projects, with off-peak tariffs set at a flat rate of INR2.29/kWh (US$0.029/kWh) and peak tariffs to be determined through the tender’s reverse auction mechanism.
Bid submission deadlines are at the end of July and in early August.
