Resumé

The Metropolitan Copenhagen Heating Transmission Company, CTR for short, is a partnership formed in 1984 by the municipalities of Frederiksberg, Gentofte, Gladsaxe, Copenhagen and Taarnby.

CTR has the objective of supplying the individual recipient municipalities and local heat supply enterprises with district heating, primarily based on surplus heat from waste to energy plants and combined heat and power generation plants (CHP plants). Heating plants based on fossil fuels are used in peak-load and/or back-up situations.

CTR's assignments cover the purchase of heat from production units, heat generation in its own peak-load and back-up units, transport through the transmission system and sales to the five Partnership Municipalities, as well as the exchange of heat with Vestegnens Kraftvarmeselskab I/S (VEKS). Moreover, CTR is in charge of the planning, establishment, funding and further development of the entire transmission system. Finally, CTR participates as an associate by investing in and operating a geothermal facility and a test heat pump connected to the sewer from which facility heat is also received.

CTR is responsible for developing and operating the transmission system – a 54 km transmission network, 3 booster pump stations, 14 peak-load units and 27 heat-exchanger stations – from which the heat is transmitted to the local district heating systems in the partnership municipalities.

CTR's objective is to purchase, transport and supply district heating and in special situations to supplement this by production of heat from its own peak-load units. The heat is transported in a transmission system that is owned by CTR. Heat consumers in CTR's partnership municipalities – Frederiksberg, Gentofte, Gladsaxe, Copenhagen and Taarnby – meet their heating requirements through CTR via the utilization of excess heat from refuse incineration plants and CHP plants, etc.

Heat purchase, monitoring and delivery are managed from CTR's control room in Frederiksberg via an extended control, regulation and monitoring system.

CTR fills an important task in implementing the political strategy for a CO₂ neutral capital in 2025. The important and necessary green transition from fossil fuels to biomass on the power plants include not only new technical solutions to be implemented but also complicated negotiation of new contracts with the power companies in order to find solutions that support the transition. Another and even more complicated task is to convert CTR’s own fossil fuel based peak and reserve units to a CO₂ neutral production within a reasonable economical framework.
