The developer of a major Massachusetts offshore wind farm is suing its turbine manufacturer seeking to force it to stay with the project.
Vineyard Wind filed a lawsuit Wednesday in Massachusetts against GE Renewables. That comes after the parent company for GE Renewables said it would be terminating its contracts for turbine services and maintenance at the end of April.
GE Vernova says Vineyard Wind owes it $300 million for work it performed. But Vineyard Wind counters that the manufacturer remains on the hook for about $545 million to make up for a catastrophic turbine blade collapse in July 2024 and the delays that caused.
Fiberglass fragments of a blade broke apart and began washing onto Nantucket beaches in July 2024 during the peak of tourist season. GE Vernova agreed to pay $10.5 million in a settlement to compensate island businesses that suffered losses.
The lawsuit states that the project already has been significantly damaged by GE Renewable’s “inexcusably poor performance,” and allowing the contractor to back out now would case irreparable harm. Craig Gilvarg, spokesman for Vineyard Wind, said Friday that the lawsuit is meant to ensure that GE Renewables fulfills its obligations to the project “and to the people of Massachusetts and New England who are relying on the significant power and economic benefits this project is already providing.” He said Vineyard Wind is expected to provide $3.7 billion in savings to electric customers over the life of the project.
GE Vernova said the company is exercising its right to terminate agreements for nonpayment for work performed.
“The company remains committed to the safety of the wind farm and stands by our performance and our contractual obligations,” the company said in a statement. “We will vigorously defend our position through the appropriate legal process.”
Construction finished on Vineyard Wind in March, making it the first project to reach this stage during President Donald Trump’s time in office. It had already been providing power to the grid for over a year as more turbines were finished. It is expected to reach full operations in the coming months.
According to the lawsuit, GE Renewables is the only company able to perform the remaining work, and it would be virtually impossible to find another turbine supplier willing to take its place. A hearing is scheduled for Thursday.
GE Vernova has said that insufficient bonding at one of its factories in Canada was responsible for the blade coming apart and that there was no indication of a design flaw. Sixty-eight out of the 72 blades that had been installed at Vineyard Wind at the time were removed and replaced. Vineyard Wind said that set the project behind nearly two years.
The Trump administration has been particularly critical of the project because of the blade failure.
It was one of five major East Coast offshore wind projects the Trump administration halted construction on days before Christmas, citing national security concerns. Developers and states sued, and federal judges allowed all five to resume construction, essentially concluding that the government did not show that the national security risk was so imminent that construction must halt.
Vineyard Wind is a joint venture between Avangrid and Copenhagen Infrastructure Partners, located 15 miles (24 kilometers) south of Martha’s Vineyard and Nantucket, Massachusetts. It has 62 turbines that will generate a total of 800 megawatts. That is enough clean electricity to power about 400,000 homes.
