Avaada Energy, Sprng Energy, ReNew Solar Power (ReNew), and Solarcraft Power India 8 (BluPine Energy) won the Solar Energy Corporation of India’s (SECI) auction to set up 1 GW of inter-state transmission system (ISTS) connected solar power projects (Tranche XII).

Avaada, Sprng, and ReNew won 300 MW, 250 MW, and 300 MW, respectively, by quoting ₹2.52 (~$0.0303)/kWh. Solarcraft Power India 8 quoted ₹2.53 (~$0.0304)/kWh to win 150 MW capacity.

The other participants in the auction who qualified but did not win any capacities were Apraava Energy, SJVN Green Energy, and NTPC Renewable Energy.

The tender for the project was floated in October this year.

The tariff discovered represents the second lowest solar project auction tariff this year, matching NHPC’s 3 GW ISTS-connected solar auction.

The tariff was slightly higher than the lowest solar tariff this year at ₹2.51 (~$0.0302)/kWh discovered in Gujarat Urja Vikas Nigam’s auction to supply power from 500 MW of grid-connected solar power projects (Tranche-XVIII).

The power procured from the projects will be sold by SECI to different entities over the 25-year power purchase agreement (PPA) period.

The tender had specified that selected developers must commission the projects within 24 months of the effective PPA date.

The modules used in the project must be from the Ministry of New and Renewable Energy’s Approved List of Models and Manufacturers.

The developers will be responsible for identifying land, installing the project, and acquiring ownership of it, as well as ensuring that the necessary approvals and connectivity with the ISTS network are obtained to supply power to SECI.

The winners for the 2 GW ISTS-connected solar projects auction under Tranche XI in July this year comprised SAEL, ReNew, Eden Renewables, Jakson, Shiva Corporation, and Avaada Energy.

According to Mercom’s India Solar Tender Tracker, SECI has issued tenders for a total of 20.4 GW of ISTS-connected solar power projects under Tranche-I to XII.
