Key Highlights
- 198 MW group captive wind project commissioned in Karur, Tamil Nadu.
- Project to supply 31 million units of renewable power annually to Tata Steel.
- Expected to offset around 26,350 tonnes of CO₂ emissions every year.
- Wind turbine foundations completed in 126 days, installation finished in 167 days.
Tata Power Renewable Energy Limited has commissioned a 198 MW group captive wind energy project in Karur district of Tamil Nadu, making it one of the largest wind projects of its kind in the region. The project has been developed under the group captive model to supply renewable power to Tata Steel.
The wind project consists of 55 wind turbine generators, each with a capacity of 3.6 MW. It is designed to generate around 31 million units of clean electricity annually, supporting Tata Steel’s decarbonisation and sustainability objectives. The project is expected to offset approximately 26,350 tonnes of carbon dioxide emissions every year.
A key aspect of the Karur project is its execution through a self-EPC model. Tata Power Renewable Energy managed the entire scope internally, including balance of plant activities, civil works, engineering and construction, transmission infrastructure, and 33 kV systems. This approach demonstrates the company’s in-house engineering capabilities and experience in delivering large-scale wind energy projects.
The project faced several execution challenges, including the transportation of heavy turbine components and hard rock formations during foundation work. These were addressed through meticulous planning, innovative engineering solutions, and advanced machinery. The movement of over 516 cubic metres of concrete within a 12-hour operation reflected strong coordination and efficient project management.
Despite these challenges, the project was completed in record time. Wind turbine foundation work was finished within 126 days, while turbine installation was completed in 167 days, setting a new industry benchmark for execution speed in large wind projects.
Following this commissioning, Tata Power Renewable Energy’s total renewable utility capacity has reached 11.6 GW. Of this, 6.2 GW is operational, including 5 GW of solar and 1.2 GW of wind energy, with the remaining capacity under various stages of development across multiple states. The project aligns with Tata Power’s long-term goal of achieving 100 percent clean energy by 2045 and supports India’s renewable energy growth targets.
