German Offshore Wind Output Falls 16%
Offshore wind farms in German waters delivered 16% less electricity in the first half of 2021, compared with the same period of 2020.
TenneT, transmission system operator for projects in the German North Sea, said the decline was all down to the weather with less wind in the first six months of the year.
Total power generated from German offshore wind farms was 11.492 terrawatt-hours this year, down from 13.715TWh in 2020. TenneT delivered 9.673TWh in the first half of 2021, down 16% on the 11.510TWh delivered in 2020.
In the German Baltic Sea 50Hertz supplied 1.819TWh this year, down 17.5% on the 2.205TWh supplied in 2020.
TenneT chief operations officer Tim Meyerjurgens said: “The decline in fed-in offshore wind energy in Germany is purely weather-related.
“There was simply less wind on the German North Sea in the first half of 2021 than in the first half of 2020.”
However, the share of North Sea electricity in total wind power generation in Germany rose to 16.63%. That is 6.6% more than in the first half of 2020, when the North Sea share was 15.6% of the total wind power yield, TenneT said.
German onshore wind yield fell by almost 22% in the same period from around 60TWh last year to about 47TWh, TenneT said.
In the Netherlands, the TenneT offshore grid connections transmitted 2.38TWh in the first half of the year, which was 30% more than in the whole of 2020 (1.82 TWh). This is due to the further expansion and commissioning of the Borssele Beta offshore grid connection system in the second half of 2020.
