A Citizen-Governed Data Platform (CGDP) has not yet been explored to manage the power system: if both demand and offer side management has been the topic of extended research, it has been either through the techno-control and centralized decisional power, or through the social and economic incentivization and campaign awareness dynamics for either lowering consumption or consuming green energy. Some dispersed, and yet to be developed research projects, are starting to bridge social governance of energy infrastructures and technical grid and peer negotiation for common energy management (Moret, Pinson 2017, project - Mihaylov et al., 2016). However, still few research projects address the question through the complexity of autonomously managing energy as a common resources through shared governance at the local grid scale; meaning the technical and social/political issues but also the legal and economic stakes.
