2001 (unit 2) biomass (straw and wood pellets) (unit 2) 1 x 543 MW The Avedøre Power Station () is a combined heat and power station, located in Avedøre, Denmark, just south of Copenhagen, and is owned by Ørsted A/S. Avedøre Power Plant is a high-technology facility and one of the world's most efficient of its kind, being able to utilize as much as 94% of the energy in the fuel and convert 49% of the fuel energy into electricity.{{cite web |access-date=2014-03-17 |url-status=dead |archive-url=https://web.archive.org/web/20140317181930/http://www.dongenergy.com/en/business%20activities/generation/activities/central_power_stations/pages/avedoere_power_station.aspx |archive-date=2014-03-17

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. , 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 emissions with about a million tonnes.

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 natural gas, heavy fuel oil, straw and wood pellets in the same burners. It has a super critical boiler, built by the Danish company Burmeister & Wain Energy. | access-date=2010-12-18

The Avedøre unit 2 also consists of multiple sub-units. The main sub-unit, the 80 m super critical boiler is linked to a steam turbine and an 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.{{cite web | access-date=2010-05-23 | archive-date=2011-07-19 | archive-url=https://web.archive.org/web/20110719124627/http://www.isc.dk/internet/Kompetencer.nsf/ProjekterUKWeb/7F40F2C2A65423C5C12572BB003E6339?OpenDocument | url-status=dead

Avedøre unit 2 has an electrical efficiency of 49%, which makes it one of the world's most efficient. This record high efficiency is obtained when the unit is only producing electricity. When also producing heat for district heating the electrical efficiency decreases, as the heat exchange is carried out at a higher temperature. If the export of heat energy to district heating is taken into account the energy conversion efficiency reaches 94-96%, making it one of the world's most efficient combined heat and power (CHP) stations. 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, although some environmentalists question the benefits of biomass.

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