Commercial wind farms were established in India in early 1990s. During that time, the rating of Wind Electric Generators (WEG) available was 225-250 kW, tower/hub height was about 30 meters and rotor diameter of approximately 30 meters. The energy generation per kW rating of these WEGs or Capacity Utilization Factor (CUF) was also less at around 15-20%. In present scenario, much larger capacity WEGs are available with taller tower, higher rotor diameter and advanced design features. Consequently the CUF now available is almost double. Therefore, efforts have been initiated to remove old WEGs of lower rating and install larger WEGs having vastly improved design features and much taller towers to substantially increase energy generation per hectare of land area used. This process is known as “RE-POWERING”, which is the replacement of fi rst-generation small-capacity wind-turbines with modern multimegawatt wind-turbines. It is a process which with half the infrastructure, will double the capacity and triple the energy. With many states facing power shortages on one side and potential windy areas being utilized ineffi ciently on the other side, it became imperative for India to assess the potential of repowering the old wind farms in the country. The old wind-turbines with less than 500 kW range are still in operation in large numbers of windy sites ideal for modern wind power technology in the states like Tamil Nadu, Gujarat and Maharashtra. By the end of March 2009, about 23.3% of the total capacity installed in India was of less than 500 kW rating and totaling to 2386 MW. If wind turbines installed before 2002 are replaced with new machines, Tamil Nadu can increase its wind energy output by 2,500 MW. National wind resources can be utilized in more effective way to generate more energy units from the given land area. Ministry of New and Renewable Energy is alsoworking on a proposal to extend incentives to encourage the re-powering of old turbines (predominantly less than 500kW).

Report Highlights
In the above mentioned backdrop, Infraline Energy launches, as a part of it latest edition under the esteemed Business Series Report, “Repowering of Old Wind Farms: Opportunities and Challenges”. The objective of this report is to analyze the prospects of repowering in India especially in states like Tamil Nadu, Gujarat, Andhra Pradesh, Madhya Pradesh and Maharashtra. The Report provides repowering potential in India along with its salient features, benefi ts, costs, incentives and key issues and challenges that will impact the viability of this model.
