Alpha ventus was commissioned as the first German offshore wind farm in April 2010. The construction phase proper was a brief 12 months, a pioneering feat in a location with a water depth of about 30 metres and a distance from the coast of 60 kilometres.
Reflecting its role as offshore test site, alpha ventus operates two types of wind turbines with two different foundation designs. The rated output of the wind farm is 60 MW. Experience gained in construction and operation is an input into the further development and expansion of the German offshore wind power industry.
The alpha ventus offshore wind farm is a joint project of the utilities EWE, E.ON and Vattenfall. These three energy providers established the “Deutsche Offshore-Testfeld und Infrastructur GmbH & Co. KG” (DOTI) operator consortium specifically for this purpose in June 2006. The shares distribution is: EWE 47.5%; E.ON and Vattenfall each 26.25%. The total investment is Euro 250 million with the BMU (German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety) providing Euro 30 million of funds.
During the operating years from 2011 to 2015, alpha ventus fed an annual average of some 247.45 million kilowatt hours of power into the grid, equivalent to the annual power consumption of approximately 71,000 average households (3,500 kWh) in Germany. During the operating years from 2011 to 2015, alpha ventus fed an annual average of some 247.45 million kilowatt hours of power into the grid, equivalent to the annual power consumption of approximately 71,000 average households (3,500 kWh) in Germany.
If the power generated during the commissioning period is added to the five full operating years, alpha ventus has generated over 1.4 terawatt-hours of electricity since 2009.
