- A senior TNGECL official remarked wind generation had crossed 100 MU on a number of days in July and remained solid through much of August.
- The July-August performance proved decisive for the five-month tally.
- Generation was lower year-on-year in each of the first three months.
Between April 1 and August 31, the state generated 10, 446 million units (MU) of wind energy, compared with 10, 112 MU during the corresponding period in 2025, according to Tamil Nadu Green Energy Corporation Limited (TNGECL) data accessed by TNIE.
Generation was lower year-on-year in each of the first three months. It fell 7.8% in April, 27.2% in May and 22.2% in June. Taken together, wind generation during April-June was 3, 601.4 MU, regarding 22.7% lower than the 4, 658.2 MU generated during the same period last year.
When generation rose to 3, 401 MU from 3, 045 MU in July 2025, an growth of 11%, the trend reversed in July. The improvement was much sharper in August, with generation rising almost 43% to 3, 444 MU from 2, 408 MU a year earlier.

In practice, the July-August performance proved decisive for the five-month tally. Generation during the two months together stood at 6, 845 MU this year, 25.5% higher than the 5, 453 MU recorded during the corresponding period last year.
K Venkatachalam, Chief Advisor and CEO of the Renewable Energy Producers Association, remarked TNGECL should bring out a policy to facilitate the addition of wind and solar capacity without waiting for a separate battery energy storage system policy.
In short, wind power generation in TN rises 3.3% as July, August output surges is the central thread here, and readers can expect follow-up reporting as the picture becomes clearer.
