This measure will help with that, he said. "With the growth of the number of wind farms in the North Sea, it is extremely important that we do this in the most ecologically responsible way possible with minimal impact on the North Sea," said Tim van Oijen of bird protection group Vogelbescherming Nederland. "We want to keep the impact of wind farms on nature as small as possible and we are doing that with this measure, among other things," said Jetten. This will likely become standard from this autumn, including for wind farms that are still being built or will be constructed in the future. It was already known last month that the migration would cause wind turbines to rotate more slowly, or to be almost completely stopped at some point. A massive bird migration over the North Sea was predicted to take place last weekend.Įnergy Minister Rob Jetten said it was an "international first." The idea is that wind farms in the North Sea will be shut down more often from this autumn, so that migratory birds can safely travel.īird migration has been easier to predict since the end of last year, when a PhD student from the University of Amsterdam came up with an accurate model to better predict migration periods about two days in advance. Turbines that make up part of the offshore wind farms near Borssele and Egmond aan Zee were shut down for four hours on Saturday to prevent migratory birds from flying into the wind turbine blades.
