In an old wind farm in the wind-rich region of Kayathar in the Thoothukudi district of Tamil Nadu, there are 30 wind turbines, each with a 200-kilowatt capacity. Many of these turbines are nearing the end of their lifecycle of 20 years-25 years. Generally, the wind turbine generators at the end of service life exhibit high breakdown rates, require repairs and are likely to suffer from a shortage of relevant replacement parts as the technology has improved significantly over the years.What if these turbines could be removed and replaced with the latest technology wind turbine generators that are taller and more efficient? The six megawatts wind power plant would then generate 16.2 megawatts, finds a 2021 study that conducted an economic investigation of repowering existing wind farms, with Kayathar as a case study.This is just one old farm. If all the old wind farms in the southern Indian coastal state with rusty turbines and obsolete/low functioning components were to be removed and replaced with newer turbines, it would be a huge boost in terms of renewable targets. However, Tamil Nadu has thousands of turbines installed before the year 2000, with less than 550-kilowatt capacity and the state faces many challenges in repowering.Through the years, the...Read more
