4 MW Groundwater heat pump. PlanEnergi has been overall consultant and project manager for Broager Fjernvarmeselskab on the establishment of a 4 MW groundwater heat pump. The project is supported by the Danish Energy Agency’s demonstration program for large heat pumps.
Broager Fjernvarmeselskab, is basically built as a natural gas-fired heating plant, where in 2010 an additional approx. 10,000 m2 large solar heating system. Broager Fjernvarmeselskab most recently commissioned a 4.0 MW groundwater heat pump at the end of 2016. The heat pump is expected to deliver approx. 3/4 of Broager Fjernvarmeselskab’s heat demand of 24,900 MWh/year. The heat pump is dimensioned so that – in combination with the cogeneration plant’s new accumulation tank of 5000 m3 – it is expected to be in operation approx. 5,000 hours annually and thus can increase the plant’s ability to integrate fluctuating electricity from wind power and solar cells.
The participants in the project “Groundwater heat pump for Broager” are Broager Fjernvarmeselskab (builder), PlanEnergi (client consultant and project manager), ICS Industrial Cooling Systems a/s (supplier of the heat pump), A. Højfeldt A/S (supplier of groundwater wells, raw water stations and transmission line) and Jan Teichert ApS (supplier of building for the heat pump).
PlanEnergi has been the client’s advisor on the already built solar heating system as well as:
New electric ground water heat pump of 4 MW with a Nominal COP of 4.1
The execution of recovery and reinjection wells, all with a drilling depth of approx. 250 meters.
The transmission lines between boreholes and the plant
The installation of a new 15/0.4 kV 2000 kVa transformer to supply the heat pump
Construction of a new heat pump building with various other facilities
The construction of the new 5000 m3 accumulation tank
Application for the ‘heat pump pool’ with the Danish Energy Agency
