Germany’s first offshore wind farm “alpha ventus” has been in operation for four years and continues to work according to plan and even exceeds forecasts. From 2011 to 2014, the wind farm achieved more than 16,500 full capacity hours and produced nearly 1,000 GWh of electricity.

This means alpha ventus achieves a yearly average of close to 250 GWh, an average that exceeds the forecasts by around 7 %.

Highest production in winter months

Last year, the yield was slightly below average with 235.6 GWh, which was probably due to some components being replaced. Still, this yield exceeds the forecasts by about 1.5 %. Particularly good months for wind energy generation were January and December 2014, where alpha ventus produced more than 30 GWh each. If one takes into account the time until commission, overall the wind park has produced more than 1.2 TWh since 2009. At the moment, alpha ventus consists of 12 wind turbines, with a capacity of 5 MW each: six Areva M5000 turbines and six REpower 5M turbines.

After the successful completion of alpha ventus, EWE, E.on and Vattenfall currently have several offshore projects near the German coast in their pipeline or have already realized them. These include the offshore windfarm Riffgat (108 MW) by EWE, Amrumbank West (288 MW) by E.on and Vattenfall’s DanTysk (288 MW).
