Renewable energy communities and the ecological transition: A game theoretic bargaining approach

Renewable energy communities (RECs) are considered a key initiative for ecological transition by international institutions and policymakers. In our article, we analyze how RECs enhance cooperation in ecological transition with a game-theoretic approach. Depending on specific conditions, the interaction among RECs members can be modeled through a Prisoner’s Dilemma or a game where cooperation is the only equilibrium. A REC creates incentives for cooperation through three primary revenue sources: cost savings from self-produced and consumed energy, surplus energy sales, and government incentives. We identify the combination of these factors that leads to a cooperative Nash equilibrium, where the dominant strategy for prosumers is to create a REC with passive consumers.
