Bjæverskov District Heating

Bjæverskov District Heating is a community-driven district heating project in the Municipality of Køge, aimed at phasing out oil and natural gas boilers and replacing them with a collective, sustainable heat supply. The project is organized as a cooperative, Bjæverskov District Heating A.M.B.A., and is expected to supply district heating to up to 1,000 homes, as well as businesses and institutions in Bjæverskov. 

 A central part of the project is the utilization of surplus heat from Energinet’s substation west of Bjæverskov. The surplus heat is used as base load and supplemented by an air-to-water heat pump, a gas boiler, and a storage tank, which together enable approximately 99% electrified heat production. The building and related infrastructure are prepared to accommodate the installation of an electric boiler as well. The solution contributes to CO₂ reduction, high security of supply, and stable heating prices for consumers.  

The project was politically approved by the Municipality of Køge in 2023 following consideration of a project proposal prepared in accordance with the Heat Supply Act. Excavation work and the construction of the heating plant and pipeline network have subsequently begun, and the expansion of the district heating network will be completed in 2026–2027.  

PlanEnergi’s role:  

PlanEnergi has served as the lead consultant for Bjæverskov Fjernvarme A.M.B.A. throughout the entire project—from the initial analyses to implementation.  

PlanEnergi’s tasks include, among other things:  

• Initial screening and analysis of district heating options based on surplus heat in collaboration with the Municipality ofKøge 
• Preparation of the formal project proposalin accordance withthe Heat Supply Act, including technical solutions, socio-economic analysis, corporate economics, and consumer economics 
• Technical design of the heating plant, pipeline network, and production facilities
• Tendering and contract negotiations
• Construction management, supervision of construction meetings, and final inspections.

The Bjæverskov project is an example of how local initiatives, municipal planning, and technical solutions can be combined into a robust, green district heating project based on local surplus resources.
