This case study unravels the ambiguous position of public energy distributor Fluvius in dealing with strategic regional transition challenges. It enriches current understandings of spatial transition dimensions and of public regime actors' role in transitions, by unravelling the territorial and institutional embeddedness of regional energy distribution systems. We disentangle three controversies in Flemish energy distribution, centred around the spatial concepts of density, spatial selectivity and socio-spatial redistribution. This spatial lens reveals the implicit spatial logics and inherently political character of transforming regional distribution systems. We conclude that a fundamental energy transition requires more inclusive governance, and an ambitious spatial transition vision.
