Environmental key figures for electricity generation 2008

27 August 2009


Energinet.dk registers data concerning electricity supplies from all electricity-generating units supplying the public grid. In addition, Energinet.dk collects specific data on emissions and fuel consumption from Danish electricity and CHP generators. In 2007 data have been collected from all power generators with a capacity of more than 5 MWelectricity and/or more than 20 MWthermal. These statements cover around 92% of total Danish electricity generation. For facilities with a smaller capacity, Energinet.dk estimates the environmental impact based on data on their electricity generation, fuel types and efficiency, etc.

The table below show key figures for power generation in Eastern and Western Denmark in 2008. The key figures specify generation based on various fuel types, imports, exports, grid loss and consumption (sale to distribution). As the electricity systems in Eastern and Western Denmark are not interconnected, values for both systems have been calculated and computed.

Electricity generation ex facility (net including own consumption) 12,001 22,648 34,649
Imports, gross  4,949  7,769  12,718 
Exports, gross 2,467  8,797 11,264
Grid loss in transmission grid 359 518 877
Sale to distribution 14,124 21,102 35,266
Specification of electricity generation GWh GWh GWh
Electricity from wind turbines 1,786 5,192 6,977
Electricity from hydropower and photovoltaics 0.10 27 27 
Electricity from thermal production on RE fuels  1,549 1,708 3,257
Electricity from thermal production on non-RE fuels 8,666 15,721 24,387
Note: Renewables (RE) include electricity from wind turbines, hydropower and photovoltaics and electricity from thermal production of renewable fuels. Renewable fuels are bio fuels such as wood chips, wood pellets, wood and biomass waste, straw, landfill gas, biogas and the biodegradable fraction of waste. Non-RE fuels comprise fossil fuels such as coal, oil, natural gas, refinery gas and the non-biodegradable fraction of waste.
