For the first time in the United States, turbines are sending electricity to the grid from the sites of two large offshore wind farms. The joint owners of the Vineyard Wind project, Avangrid and Copenhagen Infrastructure Partners, announced Wednesday the first electricity from one turbine at what will be a 62-turbine wind farm 15 miles (24 kilometers) off the coast of Massachusetts. Five turbines are installed there. One turbine delivered about five megawatts of power to the Massachusetts grid just before midnight Wednesday. Danish wind energy developer Ørsted and the utility Eversource announced last month that their first turbine was sending electricity from what will be a 12-turbine wind farm, South Fork Wind, 35 miles (56 kilometers) east of Montauk Point, New York.
