In 2009 Renewable the Energy Foundation in London commissioned a study on operating conditions and spot market behaviour in Denmark for the years 2006 to 2008. During the work it was realized that German wind power and spot market data had to be included.

At the end of 2008 the installed wind power capacity was 3.3 GW in Denmark and 25.7 GW in Germany. It was a main result of the study that there is a high positive correlation between wind power variations in Denmark and Germany. The spot prices also have a high positive correlation in the two countries, but spot prices do not only depend on wind power, but on several other factors. Insufficient interconnector capacity due to poor transmission performance and restricted congestion policies plays an important role.

The study was based on three data surveys for the years 2006, 2007 and 2008. The author wants to extend the observations to a longer period and to a larger geographical area. Therefore data surveys for 2009 and 2010 have been added.

Statistical Survey 2010 includes Denmark, the four German system operators and Ireland (including Northern Ireland).

It is increasingly important to study wind power behaviour in Great Britain, but extracting relevant British data is more complicated than for the other countries. After the completion of the survey for 2010 time series for British wind power output were found. Selected results for the four countries are presented and analysed in a supplement, Enlarged Wind Power Statistics 2010.

The author

Paul-Frederik Bach has more than 40 years experience in power system planning. He worked with grid and generation planning at ELSAM, the coordinating office for west Danish power stations, until 1997. As Planning Director at Eltra, Transmission System Operator in West Denmark, he was in charge of West Denmark's affiliation to the Nordic spot market for electricity, Nord Pool, in 1999. Until retirement in 2005 his main responsibility was the integration of wind power into the power grid in Denmark. He is still active as a consultant with interest in safe and efficient integration of wind power.
