GE Vernova, which agreed to the settlement, blamed a manufacturing problem at one of its factories in Canada and said there was no indication of a design flaw. It reinspected all blades made at the factory and removed other blades made there from the Vineyard Wind location.
Crews in boats and on beaches, along with volunteers, collected truckloads of debris. The company said the debris was nontoxic fiberglass fragments and that the pieces were one square foot or smaller.
The settlement calls for establishing a fund along with a process to evaluate claims from businesses and distribute payments, Nantucket officials said.
The development's massive wind turbines with blades more than 328 feet (100 meters) long began sending electricity to the grid at the beginning of 2024.
