Update – July 25, 2025
Vineyard Wind’s construction continues to gain momentum this summer. The project is now delivering electricity from 17 turbines to the Massachusetts grid — a notable increase from just four turbines in May, according to the latest quarterly investor report released Wednesday.
This output currently represents around 220 megawatts of the planned 800-megawatt capacity, which is about 27% of total production — enough to supply clean power to more than 100,000 homes across Massachusetts. Iberdrola, the parent company of Avangrid (one of the project’s developers), also confirmed that Vineyard Wind expects to reach 30% capacity by the end of July and aims to achieve full commercial operation by the end of this year.
Windpower has faced stiff oppostion from the Trump administration issued a stop order on another off shore windfarm Equinor’s Empire Wind project early last month.
Update – June 2025
Vineyard Wind 1 — the first commercial-scale offshore wind project in the United States — is experiencing potential delays that could extend its completion timeline into 2026. Initially expected to be finished in 2024, recent updates — including an extended lease at New Bedford’s Marine Commerce Terminal — indicate that construction work will continue well into next year.
Despite Iberdrola’s statement projecting completion by late 2025, progress has remained gradual. By June 2025, only four of the planned 62 turbines were generating electricity for the grid.
Although the project has overcome legal battles and political hurdles, the remaining construction workload and the terminal lease extension through mid-2026 suggest the project may not reach full operation until next year. Vineyard Wind 1 remains a cornerstone of Massachusetts’ renewable energy goals, but its timeline remains uncertain.
Project Milestones
In August 2023, Avangrid, Inc. announced that Vineyard Wind 1 had successfully installed its first GE Haliade-X Wind Turbine Generator (WTG) — the largest turbine in the Western Hemisphere at the time. Each turbine features a tower, three blades, and a nacelle, with a nameplate capacity of 13 megawatts, capable of supplying over 6,000 homes and businesses.
When completed, Vineyard Wind 1 will deploy 62 turbines with a total capacity of 806 megawatts, enough to power more than 400,000 Massachusetts homes. Offshore construction began in late 2022, with the project reaching steel-in-the-water status by June and completing the nation’s first offshore substation by July. The New Bedford Marine Commerce Terminal serves as the main hub for construction and staging. Notably, Vineyard Wind signed the first Project Labor Agreement for a U.S. offshore wind farm in July 2021, committing to create 500 union jobs through the project.
About Vineyard Wind 1
Located 15 miles off Martha’s Vineyard, the Vineyard Wind 1 project is designed to deliver significant clean energy and economic benefits. When fully operational, the project is expected to provide electricity for over 400,000 homes and businesses in Massachusetts, generate 3,600 full-time equivalent (FTE) job years, save customers approximately $1.4 billion over its first 20 years and cut carbon emissions by over 1.6 million metric tons annually, equivalent to removing 325,000 cars from the roads each year.
Tim Evans, Partner and Head of North America for Copenhagen Infrastructure Partners (CIP), emphasized:
“This completed turbine represents the dedication of our construction and project teams, along with invaluable support from local communities. Vineyard Wind is the future of U.S. offshore wind — bringing clean, sustainable energy, new jobs, and major carbon reductions. Offshore wind remains a critical pillar of our investment strategy, with the U.S. market at its core.”
