Repowering a Windfarm — A Techno-Economic Approach

Abstract

Repowering one of the old Indian wind farms located at a potential wind site is discussed. Various options of repowering have been suggested and compared based on annual energy production and levelised cost of generation. Economic performance indices of repowering in the current wind power policy scenario have been evaluated and the feasibility is discussed. The study infers that partial repowering could be economically more attractive than total repowering, whereas total repowering of old wind farms located at potential sites would be essential to meet renewable energy targets of a nation like India.
