December 16, 2025 — After months of pressure from local leaders, Nantucket has won new guarantees from Vineyard Wind, securing an agreement that sets clearer rules for communication, public transparency, and emergency response as the offshore wind project progresses toward full operations.
The agreement was formally announced on Dec. 11.
Town leaders first raised the issue publicly in July, when they called for more consistent and transparent information about the project’s daily activities and a more reliable process for handling emergencies at sea. They said the town had struggled to get quick, detailed answers, and they wanted a system that let both officials and residents track what the project was doing.
Select Board member Brooke Mohr, who led the island delegation in the talks, said the push centered on protecting the island’s natural and economic landscape.
Many issues arose in the aftermath of the catastrophic failure of a blade on turbine AW-38 in July 2024, which sent tons of debris crashing into the ocean and then washing up on Nantucket’s south shore and elsewhere throughout the region. Others are related to the light pollution from the turbine field.
“Transparency and predictability are essential to protect our world-renowned coastline, fisheries, night skies, and heritage tourism economy,” she said.
Nantucket is listed as a national historic landmark.
The company is constructing its 62-turbine, 800- megawatt Vineyard Wind 1 project — a joint venture of Avangrid Renewables LLC and Copenhagen Infrastructure Partners — in waters starting about 15 miles southwest of Nantucket. The company earlier this month reported the project is progressing and has a current operational capacity of more than 400 megawatts.
