Highlighting the state’s leadership in clean energy, Sivasankar noted that Tamil Nadu currently has over 20 GW of installed renewable capacity, including more than 10 GW from wind. “With a renewable addition of 2,786 MW in 2024-25 alone, we are proud to drive India’s net-zero ambitions and pilot future-ready energy solutions,” he added.
Tamil Nadu produces 500 MW of wind blades and turbines annually, alongside 3,000 MW of solar panels, wafers, and related components. The state ranks third nationally in total renewable energy capacity at 25,500 MW, second in wind at 11,500 MW, fourth in solar at 10,700 MW, and has 2,323 MW of hydro capacity, he said.
In FY24-25, Tamil Nadu added 2,014 MW of solar capacity, and 1,136 MW of wind capacity via STU/CTU. Rooftop solar installations have also surged, with 588 MW in commercial and industrial connections, including 290 MW under the PM Surya Ghar scheme benefiting 34,757 consumers, and 100 MW outside the scheme across 12,884 consumers. So far in FY25-26, the state has already added 593 MW of solar, 160 MW of rooftop solar, and 68 MW of wind, stated Sivasankar.
The state has been identified as a prime hub for offshore wind, with an estimated 35 GW potential off the Tamil Nadu coast. This, combined with solar and storage, will enable 24/7 renewable power supply. Battery storage and smart grid integration projects are advancing, including a 500 MW/1,000 MWh BESS project expected to begin commercial operations by December 2026, along with upcoming tenders for 375 MW/1,500 MWh BESS and 30 MW/90 MWh solar BESS plants.
