In light of the ambitious targets for long term decarbonisation set by the European Green Deal, a critical question for decision-makers is how to sustain a coal phase-out that is as swift as possible while also ensuring security of supply, affordable electricity, and a just transition in regions dependent on coal. The aim of this report is to support decision makers in Bulgaria, Greece and Romania to implement a timely phase-out of coal by analysing the impact on electricity systems as well as the local economy, and highlighting policy recommendations to deal with potential issues related to compensation, system security and local economic impacts.
