Offshore Wind Joint Venture Vineyard Wind 1 Reaches Regulatory Milestone

LCG, March 10, 2021--AVANGRID, Inc. announced yesterday that the U.S. Bureau of Ocean Energy Management (BOEM) has issued the Final Environmental Impact Statement (FEIS) for Vineyard Wind 1, located approximately 15 miles off the coast of Martha's Vineyard. The issuance of the FEIS is the last step prior to a Record of Decision (ROD) from BOEM, the last approval required for construction on the project to commence. The project is under development by Vineyard Wind, a joint venture between Avangrid Renewables, a subsidiary of AVANGRID, Inc., and Copenhagen Infrastructure Partners (CIP).

The FEIS is conducted by BOEM to evaluate the potential environmental impacts of the proposed project and informs BOEM's Record of Decision, which will be issued after a 30-day period. With the issuance of the FEIS, Vineyard Wind confirmed that the project remains on track to reach financial close in the second half of 2021 and begin delivering carbon-free electricity to Massachusetts in 2023. Vineyard Wind had submitted the Construction and Operations Plan (COP) to BOEM for the Vineyard Wind 1 Project in December 2017.

Massachusetts state law seeks to have 3,200 MW of offshore wind capacity by 2035, and the addition of the Vineyard Wind 1 project, with a capacity of 800 MW, will be a big step towards achieving that objective.

The project plans now call for using GE's Haliade-X wind turbines, which include a 220-meter rotor and a 107-meter blade. GE Renewable Energy announced last October that its Haliade-X prototype had been optimized and is now operating at a 13 MW power output.

AVANGRID's CEO stated, "We are one step closer toward realizing this historic clean energy project and delivering cost-effective clean energy, thousands of jobs and more than a billion dollars in economic benefits to Massachusetts. BOEM's thorough review of Vineyard Wind 1 ensures that both the project and the offshore wind industry are well-positioned for long-term success."

Avangrid Renewables is also a partner on Park City Wind, an 800 MW project to serve the state of Connecticut, as well as on additional lease areas off the coast of Massachusetts and Rhode Island to deliver up to 3,500 MW. In addition, Avangrid Renewables is developing Kitty Hawk Offshore Wind that has the potential to deliver 2,500 MW of clean energy into Virginia and North Carolina.
