DONG Energy is among the world leaders when it comes to expertise in design, construction and operation of efficient, cutting-edge power stations. Our multi-fuel Avedøre Power Station in Denmark reaches high fuel efficiencies of up to 94 % by simultaneously generating heat and power.
The higher the fuel efficiency, the less fuel is needed per kWh generated, and the less CO2 is emitted per kWh
- High fuel efficiencies of up to 94 %
- Multi-fuel system
- Useful high-quality by-products
The multi-fuel Avedøre Power Station in Denmark ranks among the best in the world. It has a total capacity of approximately 810 MW. Avedøre Power Station supplies 200,000 households with heat and generates about 30 % of the electricity consumption on Zealand, equivalent to the annual electricity consumption of around 1.3 million households.
Simultaneous heat and power generation
By simultaneously generating heat and power the power station reaches record-high fuel efficiencies of up to 94 %. The higher the fuel efficiency, the less fuel is needed per kWh generated, and the less CO2 is emitted per kWh.
Fuel efficiencies of up to 94 %
Avedøre Power Station consists of two power station units: Avedøre 1 and Avedøre 2. Avedøre 1, from 1990, primarily uses coal as fuel and, by using combined heat and power generation, is capable of utilising more than 90 % of the fuel’s energy content.
Avedøre 2, from 2001, is a multi-fuel system, which utilises natural gas, oil, coal, straw and wood pellets and can reach fuel efficiencies of up to 94 %. The efficient fuel utilisation in Avedøre 2 has been achieved by increasing steam pressure and steam temperature to levels rarely seen elsewhere.
Meeting peak demands
Avedøre 2 consists of a steam turbine system, a gas turbine system and a straw-fired biomass system. The biomass station is the largest of its kind in the world to date. It has a capacity of 45 MW and takes 25 tonnes of straw per hour.
The gas turbine functions as a peak-load plant that is primarily brought on line mornings and evenings when demand for electricity peaks.
Utilising by-products
NOx, SO2 and fly ash are removed from the flue gases before they are released to the atmosphere. This process produces high-quality by-products that are used to make products such as gypsum, concrete blocks and insulating material.
