The Gujarat Electricity Regulatory Commission (GERC) has adopted tariffs in the range of ₹185,390 (~$2,034)/MW to ₹189,000 (~$2,074)/MW per month discovered under the competitive bidding process conducted by Gujarat Urja Vikas Nigam (GUVNL) for the procurement of power from 2 GW/4 GWh standalone battery energy storage systems (BESS) under Phase VII.

The Commission approved a total capacity of 1.665 GW/3.33 GWh in favour of the successful bidders.

The successful bidders are Sun Drops Energia, Engie Energy India, Mecpower Solutions, Samavist Energy Solutions, Stockwell Solar Services, Solar91 Cleantech, Viviana Power, Rajesh Power Services, and Ultimate Flexipack.

The Commission directed GUVNL to execute the battery energy storage purchase agreement (BESPA) with the successful bidders.

Background

GUVNL floated a tender last July to procure power from 2 GW/4 GWh standalone battery energy storage systems under tariff-based global competitive bidding, with support for viability gap funding.

A total of 19 bidders, with an aggregate qualified capacity of 7.045 GW/14.090 GWh, participated in the e-reverse auction.

In the e-reverse auction, nine bidders were declared successful for a capacity of 1.665 GW/3.33 GWh, and the discovered tariff ranged from ₹185,390 (~$2,034)/MW per month to ₹189,000 (~$2,074)/MW per month.

The Commission noted that GUVNL is purchasing power on behalf of four distribution licensees in the state.

Accordingly, GUVNL procures renewable power and storage capacity by entering into power purchase agreements and BESPA with various project developers and energy storage developers from time to time to fulfill its renewable purchase obligation.

Commission’s Analysis

The Commission noted that the bidding process was conducted through a competitive mechanism followed by an e-reverse auction.

GERC observed that GUVNL had complied with the technical requirements set by international and national standards.

Accordingly, the Commission decided to adopt the discovered tariff for 1.665 GW/3.33 GWh capacity under Phase VII.

It directed GUVNL to disclose the names of the successful bidders and the tariffs quoted by them on its website for 30 days.

In October last year, GERC upheld GUVNL’s cancellation of both the base capacity of 250 MW/500 MWh and the additional greenshoe capacity of 250 MW/500 MWh awarded to Gensol Engineering to set up standalone battery energy storage systems.
