The Dutch utility’s 70-turbine project, with a 3MW capacity each, is planned 26km west of the town of Bergen aan Zee, in the North Holland province.
The final permit for the 21 square kilometre, Q4 West, follows a shift in its planned location to avoid disruption to major shipping lines.
Q4 West lies directly behind the 78MW wind plant Q4, which Eneco obtained a permit for in 2009.
However, Eneco states: "There are no concrete plans for the realisation of these two wind farms at present".
As a result of Q4 West being permitted, Eneco's 2009-acquired permit for the 212MW Scheveningen Buiten project was withdrawn.
