Wind energy repowering decisions are multifaceted and depend on the physical, political and social landscape, as factors such as noise regulation, aesthetics and political bargaining can significantly influence project development. Policy should recognise that a technology perspective alone cannot inform implementation pathways and should be supplemented with an understanding of the political and social dimensions.
Messages for policy
Wind energy repowering is a negotiated process that involves the increase of clean energy supply as well as the creation of opportunities to reduce community impacts of wind turbines.
Active policy focus on repowering can, with a robust understanding of its multifaceted drivers and decision processes, exploit the opportunities and maximize the potentials and benefits of repowering.
The relevance of policy focus on repowering will increase with time as turbine fleets age, wind energy use increases around the world and the cumulative effects of deployment become more prominent.
Noise regulation, aesthetic principles and political preferences are important drivers in repowering and can lead to earlier and more dismantling of turbines that have impacts on local communities.
Estimations of repowering potentials (for example, net capacity increases) may decrease when considering the breadth of physical, social and economic factors that ultimately drive repowering decisions.
