The average wind speed at the site is about 10m/s which creates an output of up to 3,620 net full load hours. This is more than twice as much as could be expected from a good onshore coastal site, justifying the higher cost for offshore installation and maintenance. Once operational, the 54 turbines of the 6MW-class will produce on average 1,2 billion kilowatt hours per year.

This means that Nordsee One will be able to provide for the power consumption of approximately 400,000 average households and will save over one million tons of CO2 compared to a conventional coal fired plant.
