In Short : In a significant renewable energy milestone, wind power met nearly 30% of Tamil Nadu’s electricity demand for two days in May 2025, delivering over 100 million units daily. This early wind surge, driven by the southwest monsoon, marks a record for May. Tamil Nadu, with over 11,400 MW capacity, continues to lead India’s wind energy push.
In Detail : In a notable achievement for renewable energy, Tamil Nadu saw wind power supply nearly 30% of its total electricity needs over two consecutive days in late May 2025. This surge in wind energy contribution is being hailed as a major milestone for the state, known for its leadership in wind energy generation in India.
On May 27, wind turbines across Tamil Nadu generated 101.13 million units (MU) of power, which accounted for nearly a third of the total 334.91 MU consumed in the state. The following day, May 28, wind energy generation rose slightly to 103.90 MU, against a slightly lower overall demand of 333.57 MU.
This is the first time wind power generation has crossed the 100 MU mark in the month of May. Typically, such output is recorded from June onwards with the onset of the southwest monsoon. This year, however, the early arrival of monsoon winds contributed to the unexpected boost in wind generation.
Tamil Nadu remains one of India’s leading states in renewable energy, with an installed wind power capacity of 11,409.68 megawatts (MW). The state ranks second only to Gujarat in terms of capacity, and annually, it generates around 13,000 MU from wind energy, contributing approximately 9.91% of its total power consumption.
To strengthen this sector further, the Tamil Nadu government has introduced the Wind Repowering Policy 2024. The policy is designed to upgrade aging wind turbines and facilitate hybrid energy projects, thereby improving efficiency and ensuring more consistent energy output from renewable sources.
These developments signal Tamil Nadu’s strong commitment to sustainable energy and its proactive approach to enhancing energy security. With favorable policies and natural wind potential, the state is poised to further expand its renewable energy footprint in the coming years.
