Construction of the South Fork Wind offshore wind project is complete, about 21 miles southwest of Martha’s Vineyard.
New York Gov. Kathy Hochul announced the news Thursday, with U.S. Secretary of the Interior Deb Haaland and other officials in attendance.
The project’s full complement of 12 turbines have been installed; an unspecified number are fully operational and sending consistent power to the grid.
Hochul said in a news release that South Fork is delivering power and that “commissioning” — which typically includes testing and checking a system to place it into full operation — is “in its final stage.”
Ørsted, which owns the project 50-50 with Eversource, said 12 turbines had been “powered up.”
South Fork Wind began delivering power from its first turbine in December as construction continued.
Cables bring the electricity ashore on Long Island.
The project is less than one-fifth the size of Vineyard Wind, but it’s the largest U.S. offshore wind farm to be completed since the Block Island Wind Farm opened with five lower-capacity turbines in 2016.
Meanwhile, Vineyard Wind is building 62 turbines. So far, at least five are sending power to the grid.
