As of 30 April 2026, Copenhagen Municipality reported HOFOR's targets as 300 MW of heat pumps and 550 MW of electric boilers by 2035, with district heating temperatures lowered city-wide by 2033. Two such projects are under construction.
Two plants in construction
At Herjedalgade by Kløvermarken pumping station, HOFOR is building a wastewater heat pump of 29 MW (municipality) or about 30 MW (HOFOR), estimated at DKK 350 million. HOFOR's 16 December 2025 press release put it in service in January 2028; its 9 August 2026 status note says the end of 2027. In Nordhavn, construction of a 24 MW seawater heat pump at Sundkrogsgade has started, estimated at DKK 391 million in 2025 prices and DKK 411 million in current prices, with installation from autumn 2026.
The next, larger step
HOFOR plans Svanemølle Energicentral with at most 50 MW of heat pumps, 200 MW of electric boilers, 140 MW of gas boilers and a 10,000 m3 heat store, at an estimated DKK 1.5 billion and with completion scheduled for 2030. It needs a new local plan. It is meant to replace heat from Ørsted's Svanemølleværket, which Ørsted wants to close.
Still under analysis
On Kraftværkshalvøen, HOFOR is analysing a seawater heat pump of at least 100 MW and an electric boiler of about 30 MW, with a possible further 100–200 MW boiler and a 65–85,000 m3 heat store. As of April 2026 it had not been decided.
Investment level
HOFOR invested DKK 3,411 million across the group in 2025 and expects that high level to continue, especially in electrifying district heating.
How HOFOR buys, which water and wastewater tenders are open now and where suppliers should focus first are set out in the brief. The full report, HOFOR: Utility Account Brief, is available for USD 499. For a free overview, read the HOFOR Utility Snapshot.
