Vineyard Wind’s delay in securing a final federal permit to start construction hasn’t dented widespread interest from banks and investors, who remain ready to provide debt and tax equity finance for the pioneering $2.8bn US offshore project.

They expect the Department of Interior (DOI) to greenlight the planned 84-turbine, 800MW array off the southern coast of Massachusetts in 2020, after President Donald Trump’s administration last week re-affirmed that offshore wind is an important component of its “America First” energy strategy.
