Wind Power and Spot PricesIn Great Britain it has been a widely accepted assumption that the high Danish share of wind energy could easily be replicated by other countries.
In order to examine this assumption the Renewable Energy Foundation in November 2008 asked me to analyse the impact of wind power on the spot market in Denmark.
Data for the years 2006 to 2008 were downloaded from Energinet.dk's web site. When a significant interaction with the German market was observed additional wind power data from the German E.ON Netz control area were downloaded as well.
The analyses did not show any convincing correlation between wind power and spot prices, but the following observations deserve attention:
Therefore it is more reasonable to say that Denmark and Germany together have integrated 7% wind energy than to emphasize Denmark's 20%.
The observations underline the significance of sufficient capacity and high availability of interconnections.
Extended wind power capacity will put pressure on the spot market. Therefore it is important henceforward to monitor the quality of the market service and to implement the measures considered to be required for maintaining an efficient market service and a secure supply of electricity.
