America’s first large-scale offshore wind farm reaches financial close

Vineyard Wind, a joint venture between Avangrid Renewables and Copenhagen Infrastructure Partners (CIP), has reached financial close on its 800 MW offshore wind farm in Massachusetts — the first large-scale offshore wind farm in the United States and the Americas region.

The developer has raised $ 2.3 billion of senior debt through nine international and U.S. banks to finance the construction of the project, which now enables Vineyard Wind to give the go-ahead to its contractors.

At $ 2.3 billion, Vineyard Wind 1 represents one of the largest investments in a single renewable energy projects in the U.S.

Vineyard Wind 1 is also the first commercial scale offshore wind farm in the U.S. to achieve financial close, which comes a few months after the project was approved by the government and received the U.S. Environmental Protection Agency’s (EPA) final Clean Air Act Outer Continental Shelf air quality permit.
