Five municipalities have joined forces in the Greater Copenhagen Area to produce a common district heating system. In 1984 the municipalities of Frederiksberg, Gentofte, Gladsaxe, Copenhagen, and Taarnby formed the Metropolitan Copenhagen Heating Transmission Company – CTR.

The main objective of CTR is to utilize waste heat from refuse incineration plants and combined heat and power plants (CHPs). The company is responsible for purchasing heat from production units and transporting this heat through the transmission net for sale to its five owners and to VEKS – CTR’s affiliated company to the west. CTR also operates backup units and produces heat on its own account during peak load periods. To fulfill all these tasks, CTR has laid a 54-kilometer (34 miles) long pipeline using 3 booster pump stations, 14 peak load units, and 26 heat exchanger stations to transfer the heat to the local district heating systems. All these installations are managed from CTR’s central control room in Frederiksberg, using computer-based control, regulating, and monitoring systems.
