The foundations were erected at water depths between 26 and 29 meters. The work lasted only 4 months. Tim Kittelhake, Managing Director of Nordsee One GmbH, said « In the days ahead, we will begin installation of the inter-array cables, and this summer we will install the substation. We expect wind turbine installation to begin early in 2017 ».
The wind farm is expected to produce an annual output of more than 1,200 gigawatt hours of electrical energy, enough to supply the equivalent of some 400,000 German households.
Hans Bünting, COO Renewables RWE International SE, explained: « We have reached this important milestone ahead of schedule and within budget. This outcome is the result of precise planning and efficient execution ».
Owned at 85% by Northland Power Inc, and 15% by RWE Innogy GmbH, Nordsee One has a total area of 41,3km², located 45km north of the Juist island. 54 wind turbines will produce on average 1,2 billion kilowatt hours per year, saving over one million tons of CO2 compared to a conventional coal fired plant.
