To meet energy demand and achieve climate and energy decarbonisation targets, cities adopt a range of mechanisms to facilitate renewable electricity development from their surrounding regions. These mechanisms are likely to have implications for regional community co-benefits, social acceptance of renewable energy projects, and energy justice. This research used document analysis to identify the procurement mechanisms being used by cities to source renewable electricity from surrounding regions and the types of actors involved. The analysis focussed on 27 cities pursuing ambitious 100% renewable energy or carbon neutrality goals and whose plans indicate engagement with their surrounding regions. The results point to eight types of mechanisms used by cities to develop renewable energy in their surrounding region. Of the 56 occurrences identified, 55 involved public actors, 25 involved private actors, and 12 involved civic actors. The findings demonstrate that cities are overcoming their local energy constraints by seeking to develop renewable electricity in their surrounding regions utilising mechanisms that are dominated by the involvement of public and private actors, leaving civic actors underrepresented.
