The notice was released on April 4, 2025. The last date for bid submission is April 23, 2025.
The selected consultant will be responsible for conducting surveys, preparing technical reports and drawings, and supporting the bid process. These tasks are part of the project preparation and execution support framework.
The project is planned under the public-private partnership (PPP) mode. It will be developed by Tamil Nadu Generation and Distribution Corporation Limited (TANGEDCO) in Coimbatore district.
The scheme proposes to use the elevation difference between the existing upper and lower Aliyar dams. These dams are located across the Aliyar river in the Bharathappuzha river basin. The pumped storage project is expected to enhance grid stability and support Tamil Nadu’s renewable energy goals by providing balancing capacity.
