The federal government put the country’s first large scale offshore wind farm project on hold Friday, citing concerns from commercial fishermen and other stakeholders. 

The Interior Department is ordering further study of the Vineyard Wind project which was scheduled to begin construction this year. 

Tensions between Vineyard Wind and New England commercial fishermen have intensified over the last few years. Fisherman have been concerned that offshore wind farms will adversely impact the fisheries they rely on and make their jobs more unsafe. 

The move may delay onshore construction of Vineyard Wind’s 84-turbine wind farm. The company planned to begin work before the end of this year to take advantage of a federal tax credit that is set to expire in 2019. The announcement from BOEM may put the project’s timeline and the developer’s tax credit worth millions of dollars in flux. 

In a statement, Vineyard Wind said the delay was a “surprise” and “disappointment” and has vowed to continue with the $2.8 billion project under a revised schedule. 

The delay has the potential to affect not just Vineyard Wind, but also the 14 other active offshore wind projects in the works across the Northeast.
