The Avedøre Power Station (

combined heat and power) and heat for district heating at the same time is widely used in Denmark and the rest of Scandinavia
, due to the need of domestic (and industrial) heating together with the Danish energy companies putting a big effort into optimising the energy plants.

The Avedøre Power Station was designed by the architects Claus Bjarrum and Jørgen Hauxner.

Avedøre unit 1

Having been built in 1990 this is the oldest unit. Coal was the primary fuel used in this unit, but oil can also be used. By utilising the excess heat from the power production for district heating, Avedøre unit 1 attained an energy conversion efficiency of up to 91%. This made Avedøre 1 one of the world's most efficient coal-fired power plants. As of 2015, it is being converted from coal to wood pellets at a price of DKK 740 million. It will burn 1.2 million tonnes of wood pellets per year, reducing CO2 emissions with about a million tonnes.[2]

Having been built in 2001 this is the newest and most efficient unit at Avedøre Power Station. It is able to burn a wide variety of fuels like

wood pellets in the same burners. It has a super critical boiler, built by the Danish company Burmeister & Wain Energy.[3]
The Avedøre unit 2 has a production capacity of 585 MW of electricity and 570 MW of heat and is the most efficient of the two units.

The Avedøre unit 2 also consists of multiple sub-units. The main sub-unit, the 80 metres (260 ft) super critical boiler is linked to a

electrical generator. One of the world's biggest biomass boilers also is connected to this in parallel to the turbine. Furthermore, unit 2 comprises two separate gas turbines with a capacity of 110 MW each.[4]

Avedøre unit 2 has an

combined heat and power (CHP) stations.[1] In preparation for conversion to 100% biomass in 2027, the plant has received a 360 tonne crane capable of transferring 800 tonnes of wood pellets per hour from ship to shore,[5] although some environmentalists question the benefits of biomass.[6]

As a by-product, high quality plaster is made when cleaning the flue gas.
