The Solar Energy Corporation of India Limited (SECI), a Government of India enterprise, has issued a new Request for Selection (RfS) for the development of 600 MW of Inter-State Transmission System (ISTS)-connected wind power projects across India. This tender, known as SECI-Tranche-XIX, marks another significant step in India’s clean energy expansion and aims to attract Wind Power Developers (WPDs) through a competitive tariff-based bidding process. The official RfS document, released on October 15, 2025, carries the reference number SECI/C&P/IPP/12/0013/25-26. SECI will act as the intermediary procurer for the generated power, which will be sold to the Punjab State Power Corporation Limited (PSPCL) under a long-term arrangement.
The tender offers a total capacity of 600 MW, with the option to extend by an additional 300 MW under the “Greenshoe Option.” Developers selected under this scheme will be required to develop the projects on a Build Own Operate (BOO) basis. Each project will be governed by a Power Purchase Agreement (PPA) for a duration of 25 years, ensuring long-term stability and revenue certainty for developers. The projects must be ISTS-connected and can be located anywhere in India, giving bidders flexibility in choosing suitable sites based on resource availability and logistics.
As per the tender guidelines, each bidder must propose a minimum capacity of 50 MW, while a maximum of 300 MW may be allocated to any single corporate group. The bidding will be conducted in a Single Stage, Two-Envelope format, followed by an e-Reverse Auction (e-RA) to determine the final tariff. This process ensures transparency, competition, and value for money in tariff discovery. Developers will also be required to maintain a minimum annual Capacity Utilization Factor (CUF) of 22%, with energy supply kept within 80% to 120% of the declared or revised annual CUF over the 25-year contract period. This stipulation ensures consistent and efficient performance from the wind projects throughout their operational life.
Participation in this RfS comes with important financial requirements. The non-refundable cost of the RfS document is INR 50,000 plus applicable GST. The Earnest Money Deposit (EMD) has been fixed at INR 13,32,000 per MW per project. Developers can submit this amount through a Bank Guarantee, Payment on Order Instrument from REC or PFC, or an Insurance Surety Bond. These measures ensure that only serious and financially capable bidders participate in the process.
Once selected, the successful bidder must provide a Performance Bank Guarantee (PBG) of INR 33,30,000 per MW per project before signing the PPA. This guarantee secures the project’s implementation and compliance with the tender conditions. Developers must also apply for grid connectivity within 30 days from the effective date of the PPA, marking an important milestone toward project execution. Any failure to meet financial closure or other contractual obligations within the prescribed timelines could result in the encashment of the PBG.
The bid submission deadline and technical bid opening dates will be announced as per the Notice Inviting Tender (NIT) on the ISN-ETS portal. SECI will inform all eligible bidders of the e-Reverse Auction date and time through official communication once technical and commercial evaluations are completed. The bids will remain valid for up to 12 months from the last date of submission. This tender reinforces SECI’s continued commitment to expanding India’s renewable energy capacity and accelerating the country’s transition toward sustainable, clean power generation.
