On May 15, Greece officially closed the Agios Dimitrios power plant, ending over four decades of operation at one of the largest lignite-fired power facilities in southeastern Europe. With an installed capacity of 1,595 MW, this plant has historically been a cornerstone of Greece’s coal-based electricity generation and ranked among the most significant thermal power stations in the Balkans.
This closure is a pivotal moment in Greece’s comprehensive decarbonization strategy, particularly for the Public Power Corporation (PPC). The Agios Dimitrios facility was vital for industrial growth and played a key role in ensuring a stable national electricity supply. Its shutdown will have profound implications for thousands of workers who relied on the plant and the adjacent lignite mines for their livelihoods.
Environmental ramifications have been substantial, with estimates indicating that since the EU emissions trading system began in 2005, the plant emitted close to 200 million tons of carbon dioxide. In 2012 alone, emissions were approximately 14.7 million tons of CO2, positioning Agios Dimitrios among Europe’s major polluters during its operational years.
However, this transition away from coal poses significant economic and social challenges, particularly for the Western Macedonia region, known for its lignite production. The shift has yet to adequately offset job losses and economic downturns, raising concerns about future financial support as the EU Just Transition funding period nears its conclusion.
The city of Kozani faces further complications; its district heating network has depended on Agios Dimitrios for over three decades. Local authorities are now preparing to utilize oil-based heating solutions for the upcoming winter while awaiting completion of alternative natural gas infrastructure.
This development has also sparked renewed discussions regarding the future configuration of Greece’s electricity market. Experts and environmental advocates are debating whether renewable energy sources will sufficiently replace lost lignite production or if fossil gas will assume a more prominent role in electricity generation. This shift could significantly impact both climate objectives and electricity pricing moving forward.
