Coal-Fired Plants in Denmark
Avedore
Location: Denmark
Operator: Dong Energy A/S
Configuration: 1 X 250 MW, 1 X 570 MW CHP
Operation: 1990-2002
Fuel: natural gas, coal, biomass, oil
Boiler supplier: Deutsche Babcock, BWE
T/G supplier: BBC, Ansaldo
Quick facts: Avedore supplies electricity to Eastern Denmark's grid and heat to Greater Copenhagen's district heating network. Avedore-2 has a supercritical boiler with two topping gas turbines from Rolls-Royce. It was converted to biomass fuels in Oct 2014. There is also a separate biomass combustion unit.

Asnaes
Location: Denmark
Operator: Dong Energy A/S
Configuration: 2 X 150 MW, 2 X 260 MW, 1 X 672 MW CHP
Operation: 1959-1981
Fuel: hard coal, oil
Boiler supplier: BWE, BPL
T/G supplier: BBC
Quick facts: For years, Asnaes was Denmark's largest power station, although although today only Units 2&5 are in regular operation. Asnaes also supplies heat for the local municipality and process heat for neighboring companies, some of which also use combustion byproducts for their raw material inputs. Asnaes burned orimulsion for a time, but the fule was discontinued by PDVSA in 2004.

Randers
Location: Denmark
Operator: Energi Randers A/S
Configuration: 1 X 52 MW CHP
Operation: 1982
Fuel: hard coal, oil, biomass
Boiler supplier: Deutsche Babcock
T/G supplier: BBC
Quick facts: This CHP station serves approximately 60,000 people. The unit was commissioned in 1982 with two spreader-stoker coal-fired boilers and retrofit in 2002/2003 with an Aalborg Energie Technik biomass injection port co-firing system. The plant can now run with a maximum of 75% biomass or 100% coal in single mode. The biomass system is designed for various granulated biomass products such as meat and bone meal, olive stones or shea nuts. AET handled the retrofitting of the two boilers on a turnkey basis.
