You can follow the output of the Middelgrunden wind farm online by clicking at the small carton of a turbine at the front page of this site. Please note that it requires username and code. This you can find just below the small turbine.
The budget in the diagram has been calculated based on a standard wind year, and therefore it is only an indication of the expected production.
Here you may only see the years 2001-2003 and 2009-2014. Please go to the danish page to see production for all the years.
The power curve shows how much the wind turbine can produce at a certain wind speed. The turbine starts the production at a wind speed of 3-4 metres per second and reaches maximum output at about 14 m/s.
Two power curves are shown. The guaranteed and the approved power curve. The guaranteed power curve is given by Bonus. The approved power curve is measured when the turbine got the A-certificate and gives a calculated production, which is 5,7% better than guaranteed.

Estimated electricity production
The annual production of the wind farm is estimated to be 99,000 MWh. The guarantied production is 89,000 MWh per year. The farm efficiency is estimated to be 93.3%.
The annual production of the 10 southern turbines belonging to the Middelgrunden Wind Turbine Cooperative is estimated to be 49,000 MWh. The guaranteed production of the Cooperative's turbines is estimated to be 44.000 MWh per year.
The annual production of the 10 northern turbines belonging to DONG Energy is estimated to be 50,000 MWh.
The Middelgrunden Wind Turbine Co-operative´s daily production is shown in the figure below. Only by the end of March 2001 were all the turbines released for full load at 2000 kW.
