This case study focuses on wind power development in Norrköping using a multi-level governance approach. The aim is to examine the wind power decision-making process from the state to Norrköping municipality and to identify other factors that impact wind power development in the area. A textual analysis comparing national political party platforms and local parties' official stances and interviews has been used to achieve this study's goal. The study shows that the decision-making in vertical multi-level governance is both bottom-up and top-down. It also sheds light on a significant role the Swedish Armed Forces play in this process as an external actor. The study concludes that vertical multi-level governance, including municipal veto, although an important factor, needs to be complemented with external factors to see how it affects wind power development in Norrköping.
