Tamil Nadu Green Energy Corporation Launches Hybrid Wind-Solar Project Tender To Develop 34.75 MW Green Energy Capacity

The Tamil Nadu Green Energy Corporation Limited has started an important e-tender process to boost renewable energy generation in the state by upgrading an old project and adding new capacity. The tender focuses on repowering an existing wind power plant of 18.75 MW and developing a new 16 MW solar power plant. Together, these will form a combined wind-solar project with a total planned output of 34.75 MW. The project will operate under the Build-Own-Operate model, where the selected developer will build and manage the facility and sell the generated power to the Tamil Nadu Power Distribution Company Limited through a reverse e-auction system.

The repowering and new development work will take place across four different locations in Tamil Nadu. These include Kayathar I and Kayathar II located in Kayathar Taluk in the Tuticorin District, Muppandal in Thovalai Taluk of Kanyakumari District, and Puliyankulam in Thisayanvilai in the Tirunelveli District. These sites already have renewable energy activity, and the new project aims to modernize older installations while adding solar power capacity, creating a more efficient hybrid system. Conducting the entire process through an e-tender platform ensures transparency and makes participation easier for developers.

To participate in the tender, interested bidders must submit an Earnest Money Deposit of ₹2,00,00,000, which is mandatory for all applicants. The tender has been released with a clear and fixed schedule. The publication of the tender took place on 13 November 2025 at 17:00 hours, followed by the start of document downloads on 14 November 2025 at 10:00 hours. The pre-bid query submission window was open until 25 November 2025 at 17:00 hours. The deadline for the submission of bids is set for 15 December 2025 at 14:00 hours, giving bidders sufficient time to prepare their proposals. After the submission period ends, the opening of the electronic bids will be carried out on 16 December 2025 at 14:30 hours.

This tender shows the corporation’s efforts to improve renewable energy infrastructure while ensuring that the new projects are efficient and capable of meeting future energy needs. By combining wind and solar power, the project is expected to deliver better generation stability. The upgrade of the old wind power plant will help increase output from the same locations, and the addition of the new solar plant will strengthen the hybrid system. Through this initiative, Tamil Nadu aims to make greater use of modern energy technologies and contribute to the state’s long-term clean energy goals.
