Solarworld, HG Win GUVNL 500MW/1000MWh BESS Projects

Gujarat Urja Vikas Nigam Ltd (GUVNL) has awarded its latest 500MW/1000MWh Battery Energy Storage System (BESS) projects to Solarworld Energy Solutions Limited and HG Infra Engineering Ltd at tariffs ranging from ₹2.80 lakh to ₹2.85 lakh per MWh per month. The newly discovered tariffs are about 25% lower than the previously discovered L1 rate of ₹3.72 lakh/MWh/month (without Viability Gap Funding or VGF.

According to the tender results, Solarworld Energy Solutions secured a 200MW project at ₹2,80,000/MWh/month, while HG Infra Engineering won a 300MW project at ₹2,85,600/MWh/month. The projects will be interconnected at a 66 kV level. Industry observers noted that the results mark a significant drop in BESS tariff discovery, indicating growing competition and maturity in the battery storage segment.

Incidentally, the previous tender from GUVNL at Rs 3.72 for a 500 MWh project, besides a smaller one before that. It is anybody’s guess if those projects will see the light of day if the issues plaguing the firm are not resolved soon enough.

The latest tender results were high than Telangana’s standalone BESS tender for a 500MWh (250MW x 2 hours) project was awarded at tariffs in the range of ₹2.40–₹2.45 lakh/MW/month. Issued by Telangana Genco (TGGENCO issued) in February, the tender included VGF support, and results were announced within a month. The L1 price discovered in TGGENCO’s tender was 9% higher than the lowest price found in other standalone bids with VGF.
