The average wind speed at the site is approximately 10m/s which creates an output of up to 3,620 net full load hours. This is more than twice as much as would be expected from a good onshore coastal site, justifying the higher cost for offshore installation and maintenance. The 54 turbines of 6 MW-class will produce on average 1.2 billion kilowatt hours per year.

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