Engie Energy India, NLC India Renewables, RPIL Power Three (Rays Power Infra) and Oriana Power have emerged as winners.
Engie Energy India and NLC India Renewables have won 200 MW and 600 MW, respectively, at a tariff of INR 3.12/kWh.
RPIL Power Three secured 300 MW at a tariff of INR 3.13/kWh.
Oriana Power bagged 100 MW, out of the quoted 300 MW, at a tariff of INR 3.13/kWh, under the bucket-filling method.
The tender was floated in June 2025.
The scope of work entails developing solar power projects, each integrated with a co-located energy storage system (ESS). This includes land acquisition, end-to-end project development, and establishing required interconnections with ISTS or state transmission networks.
The projects shall be located at the locations chosen by the bidder at its own discretion of cost, risk and responsibility. Projects must be commissioned within 24 months from the Power Purchase Agreement (PPA) effective date, with a grace period of six months allowed for delays. The PPA will be valid for a duration of 25 years.
The tender mandates installing ESS of at least 0.5 MW/3 MWh capacity for a 1 MW solar project capacity. It further clarified that ESS charged using a source other than solar power would not qualify as solar power. “For the avoidance of any doubt, it is hereby clarified that ESS may be owned by the SPD or may be tied up separately with a third party by the SPD, for the supply of power,” it mentioned.
The solar PV modules and solar PV cells must be from the models and manufacturers included in ALMM List-I (for solar PV modules) and ALMM List-II (for solar PV cells).
