H.C. Ørsted Power Station, situated at Sydhavnen in Copenhagen, was commissioned in 1920 and was at that time the largest power station in Denmark. Coal was its key source of fuel until 1994 when it was converted into a gas-fired power station. Today the power station is a modern CHP plant whose primary task is to supply district heating to the Greater Copenhagen district-heating network.

Its overall capacity is 185 MW of electricity and 815 MJ/s of district heat. In 2006 H.C. Ørsted Power Station generated a net quantity of 282 GWh of electricity and 3,499 TJ of district heating.  

A treasure sent to the museum
Until recently H.C. Ørsted Power Station had a B&W diesel engine from 1932 with a 12 MW generator. The engine was special because it could start up using a "dead" high-voltage electricity grid and then energize the power station’s other facilities. The engine is now on display at "DieselHouse", the museum connected to the power station.
