BackgroundWind power is a critical renewable energy technology in efforts to achieve the global climate targets. However, local impacts do occur, which demands careful consideration in planning and permitting. Sweden has set an ambition to triple land-based wind power by 2040, and municipalities play a key role in both the planning and permitting process, due to a planning monopoly and veto power in the permitting process. This calls for an investigation of Swedish wind power governance, with a particular focus on recent trends in municipal wind power planning, how wind power is balanced in relation to sustainability objectives in planning and permitting, and insights from practitioners regarding their capacities and drivers.ResultsThe results show that about two-thirds of Swedish municipalities have conducted wind power planning in some form, but this basis for decision-making has become outdated due to a lack of institutional capacity at the municipal level. Secondly, the study finds that many municipalities perceive that there are insufficient incentives for a continued wind power expansion. Lastly, the study sheds light on a large heterogeneity within wind power planning practice concerning how trade-offs between wind power deployment and other sustainability aspects are handled, as well as a lack of coherence between planning and permitting.ConclusionsIt is concluded that the current state of municipal wind power planning raises questions regarding the legitimacy of municipal decision-making in terms of perceived justice among local inhabitants and highlights the need for updated wind power plans. Moreover, to promote local acceptance in the future, formalised financial compensation and strategic initiatives that enable the localisation of electricity-intensive industry within municipalities with large-scale wind power production can be two key components. The results also highlight the need for additional support at the municipal level, including access to critical competence and relevant knowledge to enable trade-offs between the different sustainability considerations in an informed and balanced manner. Finally, regional dialogue with key actors, such as the military, Sami representatives and grid operators, would facilitate the handling of inter-municipal issues, in particular by fostering co-operation regarding inter-municipal wind sites.
