However, a key part of the National Energy and Climate Plan is to gradually phase out the use of lignite, which includes the decommissioning of all existing lignite units by 2023, except the Ptolemaida V unit, which will be closed by 2028. This plan makes Greece a frontrunner among countries who intensively use lignite in energy production. In this context, this paper investigates the environmental, economic, and social state of Megalopolis and the related perspectives with regard to the energy transition, through the elaboration of a SWOT analysis, highlighting the strengths, weaknesses, opportunities, and threats of the municipality of Megalopolis and the regional unit of Arcadia.
