Roundtable on Unlocking Wind Potential and Repowering in Tamil Nadu

Tamil Nadu has been at the forefront of India’s wind energy journey and continues to have one of the country’s largest wind fleets. As of July 2026, the state has around 12.3 GW of installed wind capacity, within a broader renewable energy portfolio of nearly 29.8 GW. Wind also remains an important contributor to Tamil Nadu’s’s electricity supply, generating 24.2 billion units in FY 2025-26. As the state works towards achieving nearly 50% renewable electricity by 2031, wind energy will remain central to meeting growing electricity demand and state’s clean energy ambitions.

Tamil Nadu has an opportunity to accelerating new wind development while maximizing the utilization of its existing wind resource base. While the State already has a large operating fleet, its underlying resource potential is significantly higher: National Institute of Wind Energy (NIWE) estimates indicate around 68.75 GW of gross onshore wind potential at 120-metre hub height and 95.1 GW at 150 metres. Unlocking more of this resource will require not only new wind projects development, but also better utilisation of existing assets, stronger evacuation and grid integration, and commercial models that respond to the changing needs of the power system.

Tamil Nadu’s mature wind fleet includes older, lower-capacity turbines in established wind-rich areas, creating significant repowering potential. Recognising this potential, the state introduced the Repowering, Refurbishment and Life Extension Policy for Wind Power Projects in 2024, followed by amendments in January 2026 to address implementation challenges and facilitate its uptake. This makes wind repowering, alongside greenfield development, an important opportunity to consider as Tamil Nadu plans the next phase of its wind sector.

To guide this next phase, Tamil Nadu Green Energy Corporation Limited (TNGECL),  with WRI India, is developing the Tamil Nadu Wind Strategy 2030 to identify key priorities and practical interventions for the State’s wind sector. As part of this effort, TNGECL and WRI India are convening a focused stakeholder roundtable bringing together wind developers, Independent Power Producers (IPPs), Original Equipment Manufacturers (OEMs), industry associations, large consumers, power-sector institutions and technical experts. The discussion will focus on greenfield wind development and repowering, with an emphasis on understanding on-ground challenges, emerging opportunities and practical measures to enable progress in these areas. Insights from the discussion will directly inform the Wind Strategy 2030 and help TNGECL identify and prioritise practical interventions to strengthen Tamil Nadu’s wind ecosystem.
