By 2030, more than 50 wind farms will have exceeded 20 years of operation in Brazil. This period is equivalent to the useful life considered in the design stage of most wind turbines in operation in the country and corresponds to the duration of the wind power generation contracts in the regulated environment.
In order to identify the challenges and opportunities related to this issue, EPE developed the Technical Note "Wind farms at the end of expected lifetime: Current Status and Upcoming Options". The document presents the alternatives commonly adopted for wind farms at the end of their useful life, international experiences with the theme, the current situation of Brazilian wind farms, including estimation of energy gains with upgrading actions, in addition to dealing with commercial, regulatory and environmental issues of energy planning.
