Introduction
On 7 October 2026 the Solar Energy Corporation of India (SECI) released a competitive tender for four ISTS‑connected wind power projects totalling 1 200 MW of capacity. The tender, part of SECI’s Tranche‑XXI series, invites developers to submit a single bid covering an integral capacity range of 50‑600 MW per project. Bidders must meet strict technical, financial and eligibility criteria, submit an Earnest Money Deposit of ₹213.68 lakh per MW and adhere to a detailed submission timeline that ends on 29 October 2026, with the techno‑commercial bids opening on 3 November 2026. This article breaks down the tender specifications, eligibility requirements, key deadlines and the broader impact on India’s renewable energy landscape.
What Does the Data Reveal About This Topic?
The data shows that SECI is accelerating the deployment of large‑scale wind power by bundling four projects into a single 1 200 MW tender, emphasising ISTS (Inter‑State Transmission System) connectivity and a transparent reverse‑auction mechanism. It highlights the financial commitment required from bidders—net‑worth of at least ₹31.368 crore per MW and liquidity metrics such as turnover of ₹82.84 lakh per MW or a bank credit line of ₹220.71 lakh per MW. The timeline also underscores a fast‑track procurement process, with only three weeks between bid release and final submission.
Tender Structure, Technical and Financial Eligibility
To qualify, developers must employ MNRE‑approved wind turbine models listed under the RLMM, install GPS‑enabled automatic weather stations and comply with grid‑code and cybersecurity standards. Financial eligibility mandates a minimum net‑worth of ₹31.368 crore per MW, calculated on the FY 2025‑26 balance sheet, and at least one of three liquidity parameters: annual turnover of ₹82.84 lakh per MW, PBDIT of ₹216.57 lakh per MW, or a bank‑guaranteed credit line of ₹220.71 lakh per MW. The Earnest Money Deposit is set at ₹213.68 lakh per MW, payable via a bank guarantee valid for twelve months with a thirty‑day claim period.
Impact on Sectors and Industries
The tender is expected to stimulate the wind‑energy manufacturing supply chain, creating demand for certified turbines, civil works, land acquisition services and grid‑integration solutions. Investors will see new avenues for equity and debt financing, while state utilities may benefit from increased renewable supply and reduced curtailment. Policy makers can leverage the project to meet India’s 450 GW renewable target, improve grid stability through ISTS connectivity, and showcase a replicable model for large‑scale wind procurement.
