Avedøre Power Station

The Avedøre Power Station (Danish: Avedøreværket) 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. Apart from using petroleum (oil) and natural gas, the plant runs on a wide variety of biomass fuels such as straw and wood pellets. The plant consists of two units with a total capacity of 793 MW of electricity and 918 MW of heat. The combination of producing electricity (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.

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 by 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. 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 steam turbine and an electrical generator. One of t
