The developer behind the Vineyard Wind offshore energy project expects the 62-turbine wind farm off the Island’s south coast could be completed by the end of the year.
During a quarterly investor call this week, executives with the project’s parent company said that 23 turbines have been fully built at the farm about 14 miles out to sea, and 17 are sending energy to the grid.
The news was the first sign of progress for the project since it got its first turbine back up and running after a turbine blade broke off last year, halting construction. Vineyard Wind, for the most part, has been quiet about the strides it made in the wake of the blade break. But during the investor’s call, Jose Sanchez Galan, the executive chairman of international renewable company Iberdrola, noted that Vineyard Wind is now nearing 30 per cent of the turbines producing power.
“In the U.S., more than one third of Vineyard Wind 1 turbines are already installed with more than 25 per cent of them already exporting energy,” he said at the July 23 meeting.
When completed, the 806-megawatt project is expected to generate enough electricity for 400,000 homes, according to the company and state officials.
Vineyard Wind was the first large-scale offshore wind energy project to get all of its approvals in the U.S., though its construction schedule was set back after the blade failure. Vineyard Wind’s manufacturer GE Vernova blamed the break on a defect that was not caught in its Canadian factory.
The federal government ordered Vineyard Wind to take down all of the blades that were from that facility, and now the company is importing the 107-meter long blades from France. A federal investigation into the cause of the failure is ongoing.
Offshore wind energy is one of the major components of Massachusetts’ plan to reach net-zero emissions by 2050 and there are several other projects in various stages off the Vineyard’s coast.
