After missing the initial goal of delivering power by the end of 2023, Vineyard Wind this week announced one of its first five wind turbines is now sending electricity to the grid.

At 11:52 p.m. Tuesday, the turbine about 12 miles off the Vineyard distributed about five megawatts of power to the New England regional grid in Barnstable, the first electricity from an offshore wind turbine in Massachusetts.

Vineyard Wind, a joint operation between Avangrid and Copenhagen Infrastructure Partners, plans to have 62 turbines that can generate about 800 megawatts of power, enough electricity for approximately 400,000 homes in the state. The company Tuesday said it expects the first five turbines could be running at full capacity in early 2024.

“Today, we begin a new chapter and welcome 2024 by delivering the first clean offshore wind power to the grid in Massachusetts,” said Avangrid CEO Pedro Azagra in a statement. “We’ve arrived at a watershed moment for climate action in the U.S., and a dawn for the American offshore wind industry.”

The project had been delayed, with company officials previously estimating that six turbines could be built and sending power through undersea cables to the mainland by the end of last year. During a tour of the construction in August, the company said the summer’s wind, rain and fog put the project behind schedule, but they were still hopeful to bring electricity in the fall of 2023. Getting the proper vessels to handle the massive construction project — the turbines are about three times taller than the Statue of Liberty — has also been hard, the company previously said.

The $4 billion project was pitched as the country’s first commercial-scale wind farm, though South Fork Wind, a smaller project off New York, delivered the first power to the U.S. in early December.

Despite the setback, state officials cheered the Vineyard Wind milestone. The project was the first to get approval in the prized 800,000 square-acre area south of the Island where several wind farms are expected to be built.

“Today marks a historic moment for Massachusetts, and indeed the nation,” said state Sen. Julian Cyr, a Truro Democrat who represents the Island in the statehouse. “This milestone is a testament to the achievements we can reach through collaboration, persistence and a dedication to a green future.”

Construction on the project began in 2022. Vineyard Wind is also working on an operations headquarters on Beach Road in Vineyard Haven and a helicopter hangar at Martha’s Vineyard Airport.
