Cogeneration is widely used in Denmark: more than 50 % of the electricity production is based on cogeneration. Electricity based on wind turbines accounts for another 20 %. More than 80 % of the heat supplied via district heating (the dominant heat supply for heating of houses) derives from cogeneration.
The EU Cogeneration Directive obliged the member states to search for further CHP potentials. In Denmark remaining CHP potentials can be found in industry and the domestic sector represented by houses individually heated via oil or gas fired boilers.
