Both supply predictions astir erstwhile and wherever birds volition be, 2 days successful advance.
"The clip span of 2 days gives grid relation TenneT clip to warrant the stableness of the high-voltage grid," authorities said. "This clip is besides utilized to pass each parties progressive and to cautiously initiate the shutdown of the turbines."
The quality represents the latest illustration of however the enactment betwixt upwind turbines and wildlife volition go progressively important successful the years ahead.
Earlier this year, it was announced that plans for an onshore upwind workplace successful Scotland had been revised, pursuing a fig of concerns that included the project's interaction connected aureate eagles.
