WIND ENERGY


DENMARK

At end-1999 Danish installed wind capacity stood at 1 771 MW. The recent rate of growth is such that by end-2000 it was reported that there were in excess of 6 000 wind turbines, representing a capacity of over 2 000 MW. The largest turbines incorporate technology that is competitive to the extent that the use of wind-produced electricity is one of the cheapest ways of reducing CO2 emissions from power production.

The 2005 target set by the Government’s Renewable Energy Initiative Package (Energy 21) (specifying that 10% of the country’s electricity demand should be met by a wind capacity of 1 500 MW) was attained prior to the end of 1999. However, as turbines have become larger, the availability of appropriate sites has decreased and it has become increasingly difficult to locate the installations. Most new capacity continues to be built by private companies.

The present Energy 21 published in 1996 is the fourth of the energy strategies and specifies energy policy for the period to 2030. Any increase in onshore wind turbine capacity after 2005 will be affected by various actions, including the renovation of wind turbine areas as well as by the removal or replacement of existing turbines in accordance with regional and municipal planning.

In the longer term the main thrust of new development will take place offshore, following the first demonstration installations at Vindeby in the Baltic Sea (1991) and Tunø Knob in the area between Jutland and Samsø (1995).

In June 1999 the Government approved five sites for large-scale offshore wind farms with a total capacity of 750 MW. The installations will be built and owned by power utilities and the first two, each of about 150 MW, are expected to be operational in 2002. However, as a forerunner to these projects, a smaller offshore wind farm (Middelgrunden, located just outside Copenhagen harbour) became operational at end-2000. With twenty 2 MW turbines producing approximately 85 million kWh of electricity per annum, this is the world’s largest offshore wind farm.

Addtionally, in order to provide the population with greater opportunities to contribute to the use of cleaner energy, small wind turbines (household-sized) producing electricity for heat and power have been erected in recent years.

Wind power economics continually improve in line with the increased turbine capacity. As a result the Danish Government has reduced the subsidy to the pay-back rate for the electricity and in 2001 a market system with Green certificates will be introduced.
