District Heating Systems

According to the decarbonisation plan for Western Macedonia, the lignite-fired units supplying thermal energy to the Kozani district heating system at the Agios Dimitrios Power Plant (PP) are scheduled for decommissioning by December 2023 (Units III and IV by December 2022, Unit V by December 2023). Similarly, the Amynteo PP (Units I and II) was decommissioned in August 2020, and the Kardia PP (Units III and IV) in April 2021.
To adapt the district heating systems of Western Macedonia to the new energy landscape, the relevant stakeholders signed a Memorandum of Understanding and Strategic Cooperation (MoU). The aim is to ensure continuous thermal energy supply during the transition period and beyond, in line with the National Energy and Climate Plan (NECP).
The MoU defines:
The geographical locations of new thermal energy production units for district heating
The roles and responsibilities of the involved parties to achieve this objective

Scope of the Interconnection Project
Interconnection facilities within the premises of the Kardia Power Plant
Interconnection facilities within the premises of DEYAK (Municipal Water and Sewerage Company of Kozani) in Kasla
Thermal energy transmission pipeline

Studies Foreseen Under the Current Contract
Technical studies (buildings and electromechanical works for pumping stations, transmission networks, tender documents, and Health & Safety Plans – HSP/FSP)
Environmental Impact Assessment (EIA)
Thermal energy distribution licence
Topographic and cadastral survey
Geological study
Geotechnical study for the pumping station
