Transitioning to low carbon energy involves policies, institutions, and actors across different scales of governance. Indonesia's aspiration for a transition to low carbon energy is occurring in the dynamics of the re-scaling of environmental governance through decentralization processes. This article examines the interplays of actors at the national and provincial levels in negotiating energy futures as the energy planning processes unfold on the ground and identifies context specific factors that shape the outcomes. Further, it investigates how the regulatory framework and institutional arrangements for energy transition planning could not only generate obstacles for renewable energy transition but also open opportunities for actions. It is based on interviews with stakeholders at national and subnational levels, combined with the analysis of policy documents, studies, and relevant reports. The findings reveal emerging spaces for local actions amid constraining regulatory and institutional fields through the process of regional energy plan development. However, the ability of sub-national actors to seize these spaces is influenced by several factors, most notably political leadership, civil society engagement, political economic structure and power relations. These in-depth insights from Indonesia have wider implications for understanding the multi-scalar dynamics of energy transitions and provide useful policy recommendations for engaging subnational actors in the transition process.
