Chairman of Indian Wind Power Association Kasturirangan has said that at a time when every unit of power generated matters to the state, Tamil Nadu has lost 100 million units of wind power last week alone. Even before the peak wind season, of July, wind flow in Tamil Nadu has been at surprisingly high levels over the last few days due to cyclone Mahasen in the Bay of Bengal.
Generation touched 4,000 mw last week, but only about 3,200 mw of this has actually been evacuated and used up by the electricity board, Kasturirangan said. For instance, according to data from the State electricity board, about 73 million units of power was generated on May 16, after 68 million units on May 15, and 58 million units the day before that.
On an average, a household uses about five units of power a day. "The previous high last year was about 4,200 mw in the peak months of July-August, but this year has already seen good wind generation. However, TNEB has been able to evacuate only up to 3,000 mw from windmills, he said.
Industry sources say that windmills are being shut down for several hours a day due to shortage of evacuation infrastructure, especially in windy areas like Theni district.
