District energy

Ramboll has played an integral part in the design of the city-wide district heating system in Copenhagen, which supplies heat to more than 1 million people. Ramboll has provided a wide variety of services to most of the transmission and distribution companies and has worked closely with all the local authorities. Overall, Ramboll has played an instrumental role in making Copenhagen an archetype of what can be achieved within district heating, multi-fuel CHP plants, waste-to-energy CHP plants, advanced heat storage, and district cooling. Moreover, Ramboll has played a significant role in developing district heating based on renewable energy, including large-scale solar water heating, biomass boilers, large heat pumps, and seasonal heat storage.
