In this paper, we aim to facilitate regional development through collaborative meta-governance processes, involving municipalities, energy companies and more actors. The case in point involves increased electrification through the development of local energy systems in a sub-region comprising 15 municipalities and 21 grid owners and is an exemplary case where a transdisciplinary engineering approach is not only suitable but the only path forward. The complex problem landscape comprises interdependencies across different roles, such as politicians, civil servants, and engineers at energy companies, where autonomous entities act independently. We employ a design science research approach to create artefacts to support the meta-governance mechanisms needed to accelerate social change processes. One artefact is a system dynamics simulation model to analyze scenarios considering the electrification of vehicles and implementing large wind and solar energy units to enable the establishment of new industries. We provide brief overviews of how three artefacts assist in visualizing 1) roles, 2) structures, and 3) scenarios to the decision-makers, to facilitate various transdisciplinary decision-making processes in regional development. In the discussion, we synthesize our learnings into a model to support mitigating powerlessness in this complex multi-stakeholder context. Finally, we lay out future research to further contribute to the social change and regional development we believe is necessary.
