The Solar Energy Corporation of India Limited (SECI) has invited bids for the development of 1,200 MW of inter-state transmission system (ISTS)-connected wind power projects (Tranche-XX) across India. The projects will be implemented on a build-own-operate basis, with SECI entering into power purchase agreements with selected bidders for a period of 25 years. Additionally, the procurement is aimed at sourcing electricity from grid-connected wind projects, with a minimum project size of 10 MW for intra-state systems and a minimum bid capacity of 50 MW for inter-state systems. The offline and online deadlines for bid submission are May 29, 2026 and June 2, 2026, respectively.
According to the tender guidelines, the scope of work includes setting up ISTS-connected wind projects along with the associated transmission infrastructure up to the delivery point. Developers will be responsible for land identification, project installation, ownership, connectivity, and securing all necessary approvals. Furthermore, the delivery point will typically be the ISTS substation, although modifications may be considered subject to agreement between the developer and the buying entity. Multiple projects may be connected to a common pooling substation, subject to approval from the Central Transmission Utility and regional load despatch centre, with energy injection data recorded and submitted as required. The bidders are required to submit an earnest money deposit of Rs 1.368 million per MW in the form of a bank guarantee, valid for 12 months from the bid submission deadline.
According to the eligibility criteria, the developers must deploy type-certified wind turbine models listed under the Revised List of Models and Manufacturers issued by the Ministry of New and Renewable Energy, and install GPS-enabled automatic weather stations in line with regulatory requirements. Financial eligibility criteria include a minimum net worth of Rs 13.68 million per MW and a minimum annual turnover of Rs 7.077 million per MW.
