The Solar Energy Corporation of India Limited (SECI) has invited bids for the development of 500 MW Inter-State Transmission System (ISTS)-connected solar PV power projects in India. The projects will be awarded through tariff-based competitive bidding (TBCB).
SECI will enter into 25-year Power Purchase Agreements (PPAs) with the selected developers, with the generated power being supplied to various buying entities across the country.
According to the Request for Selection (RfS) document (SECI-ISTS-XIX), developers will be required to set up the solar PV projects on a Build-Own-Operate (BOO) basis. The bidding process will follow a two-stage format, including an e-Reverse Auction (e-RA) to ensure competitive tariff discovery. The minimum bid size for each developer is 50 MW, while the maximum permissible allocation is 250 MW. Additionally, SECI has introduced a Greenshoe Option, allowing for an additional 500 MW capacity allocation.
To participate in the bidding, developers must submit an Earnest Money Deposit (EMD) of INR 9,42,000 per MW per project and a Performance Bank Guarantee (PBG) of INR 23,55,000 per MW per project. The successful bidders must ensure project completion by June 30, 2025.
The projects must also comply with Central Electricity Regulatory Commission (CERC) and State Electricity Regulatory Commission (SERC) regulations concerning grid connectivity, scheduling, and metering.
Under this RfS, the Solar Power Developer (SPD) will be required to set up ISTS connected solar PV power projects, including the transmission network up to the Interconnection/ Delivery Point with the primary objective of supplying solar power to SECI, at its own cost and as per the provisions of the RfS and PPA.
The SPD's sope of work also includes the identification of land, installation and ownership of the Project, along with obtaining connectivity and necessary approvals and interconnection with the ISTS network/STU or InSTS network (as applicable) for supply of power to SECI. For the purpose of STU interconnection, SPD may install the Project in the same State where the Buying Entity is located.
Interested bidders can access the complete RfS document and submission details on SECI’s official website and the ISN-ETS e-tender portal.
