Researched by Industrial Info Resources (Sugar Land, Texas)--The Biden administration said last week it aims to develop 15 gigawatts (GW) of floating offshore wind capacity in U.S. waters by 2035, following its earlier proposal to develop 30 GW of offshore wind--floating or fixed--by 2030. Floating windfarms can be positioned in much deeper waters than fixed windfarms, which account for most of the investment in offshore wind to date. Industrial Info is tracking more than $15.8 billion worth of floating offshore wind-energy projects in development across the U.S.

Whereas turbines for fixed offshore windfarms are rooted to the seabed, turbines for floating offshore windfarms are mounted to floating platforms, which are anchored to the seabed via mooring lines.
One floating wind project that has been gestating for years got a shot in the arm last month, when the Biden administration issued requests for interest (RFI) related to offshore wind projects in the Gulf of Maine. RWE AG (Essen, Germany) is proposing the Aqua Ventus Offshore Windfarm near Monhegan Island, Maine, in the Gulf. Following the successful demonstration of an 11-megawatt (MW) pilot project that is under development, RWE, in conjunction with the University of Maine and Diamond Offshore Wind (Boston, Massachusetts), expects to begin construction on an offshore windfarm that will generate 500 MW from 42 floating turbines.
The National Renewable Energy Laboratory estimates the Gulf of Maine, which includes federal waters off the Maine, Massachusetts and New Hampshire coasts, could hold up to 65 GW of offshore wind energy. The RFI, announced by the U.S. Department of the Interior, covers 13.7 million acres (5.5 million hectares) within the Gulf. Subscribers to Industrial Info's Global Market Intelligence (GMI) Power Project Database can learn more from detailed reports on Aqua Ventus and its pilot project.
The coast of New England is a popular destination for floating offshore wind proposals. Vineyard Wind LLC, a joint venture between Avangrid Incorporated (NYSE:AGR) (Orange, Connecticut), a subsidiary of Iberdrola S.A. (Bilbao, Spain), and Copenhagen Infrastructure Partners (Copenhagen, Denmark), is making steady progress on its Park City Windfarm, about 14 miles off the coast of Martha's Vineyard. It is expected to generate 804 MW from 85 floating turbines.
Earlier this month, the Martha's Vineyard Commission approved the installation of undersea cables that would send electricity generated by the Park City project to an onshore substation, according to the Martha's Vineyard Times. Subscribers can read more in a detailed project report.
Also near Martha's Vineyard is BP plc (NYSE:BP) (London, England) and Equinor ASA's (NYSE:EQNR) (Stavanger, Norway) Beacon Wind Offshore Project, which is expected to produce 1,230 MW for New York State from 123 turbines. The companies involved in the project finalized contracts with the New York State Energy Research and Development Authority (NYSERDA) early this year.
Beacon Wind's developers are considering a 1,170-MW second phase in years to come, should the first phase prove successful. Subscribers can read detailed project reports on Beacon Wind Phase I and Phase II.
The U.S. West Coast also is seeing developments of varying sizes. Trident Winds LLC (Seattle, Washington) is proposing the Olympic Coast project, offshore Grays Harbor County, Washington, which is designed to generate up to 2,000 MW from 200 turbines. Redwood Coast Energy Authority (Eureka, California) is proposing the Redwood Windfarm, offshore Humboldt County, California, which is designed to generate 120 MW from 15 turbines. Both projects are in their early site-study phases. Subscribers can learn more from Industrial Info's detailed reports on the Olympic Coast and Redwood projects.
About two-thirds of U.S. offshore wind potential is "over bodies of water too deep for fixed-bottom wind turbine foundations that are secured to the sea floor," the U.S. Department of Energy said in a press release announcing the 15-GW target. "Harnessing power over waters hundreds to thousands of feet deep requires floating offshore wind technology ... These installations are among the largest rotating machines ever constructed."
