The use of lignite as Greece’s primary source of energy will end in 2026 with the closure of the last of five units of the Agios Dimitrios Thermal Power Plant in Western Macedonia, and the conversion of the Ptolemaida V unit into an open-cycle natural gas unit. The unit was planned in 2007, with construction beginning in 2015, but was put into trial operation only in the fall of 2022 and into commercial operation in March 2023, costing power utility Public Power Corporation (PPC) 1.5 billion euros to operate for just three years. The flagship of PPC’s lignite units will go down in history as the epitome of and the most expensive monument to Greece’s absence of a long-term energy strategy.
