Tata Power Renewable Energy Limited (TPREL), the renewables subsidiary of Tata Power Company Ltd, has successfully commissioned a 198 MW group captive wind power project in Karur district, Tamil Nadu. The wind farm will directly supply renewable electricity to Tata Steel Ltd under a long-term group arrangement. The project is comprised of 55 wind turbine generators of 3.6 MW each and is expected to deliver around 31 million units of clean electricity annually to Tata Steel. This is in a bid to advance the steelmaker’s decarbonization goals.

The Karur wind farm project to power Tata steel-making operations in India

The Karur wind farm – one of the largest of its type in Tamil Nadu – will help Tata Steel offset approximately 26,350 tons of carbon dioxide emissions per year. Thiis will also help contribute to the company’s sustainability agenda. Additionally, the 198 MW Karur wind farm will continue to reinforce Tamil Nadu as the long-time backbone of India’s wind sector. Tamil Nadu ranks as number 1 in installed wind capacity in India, accounting for about a quarter of the country’s total wind power.

A key feature of the Karur wind farm project development is Tata Power’s self-EPC (Engineering, Procurement, and Construction) execution model. The company managed multiple project scopes, including Balance of Plant (BOP), civil works, transmission lines, 33 kV systems and their integration. Tata Power used in-house resources rather than relying on traditional OEM-led EPC delivery. This approach could partly ne attuned to the adherence to schedule and the demonstration of TPREL’s internal engineering and project management capabilities.

Additionally, the project achieved significant construction milestones in record time. Foundation works were completed within 126 days, and full wind turbine installations were concluded in 167 days.

What this means for Tata Power Renewable Energy and Tata Steel operations in India

The project’s completion also highlights Tata Power’s growing role in India’s transition to clean energy. Furthermore, the wind project adds to its operational renewable portfolio and continues to support Tata Group’s commitment to green power procurement.

The commissioning also strengthens TPREL’s renewable utility portfolio, which now stands at 11.6 GW. This includes both operational and under-development capacity across solar and wind assets. Furthermore, of this, around 6.1 GW is operational, comprising of approximately 4.9 GW of solar and 1.2 GW of wind energy, with an additional 5.8 GW under development across multiple states including Rajasthan, Gujarat, Andhra Pradesh, Maharashtra, Karnataka and Tamil Nadu.
