Offshore Wind: A Crucial Resource To Decarbonize The Western United States

The policy brief advocates for the development of floating offshore wind on the U.S. West Coast to meet net-zero emissions goals, noting that it can provide reliable power during peak early evening demand and reduce land-use conflicts. It highlights the economic potential for job creation and port revitalization, specifically citing the Port of Humboldt Bay. The authors call for long-term federal tax credits, port infrastructure investment, proactive transmission planning, and accelerated siting to overcome current lacks in ambition compared to the East Coast.

• West Coast offshore wind can provide affordable, reliable, clean energy at scale, which is particularly important as national electricity demand may triple by midcentury to reach net-zero emissions due to the electrification of buildings, industry, and transportation, and green hydrogen needs.
• Offshore wind is a strategic resource for the Western U.S. because it diversifies generation and reduces land-use conflicts in a region where coastal states are highly land-constrained and 80 percent of customers are served by utilities with net-zero carbon emission mandates.
• The U.S. currently lacks ambition for West Coast offshore wind compared to the East Coast, which targets over 30,000 MW by 2035. While President Biden set a national target of 30,000 MW by 2030, no specific target exists for the West Coast.
• Developing 10,000 MW of offshore wind by 2040 could create 120,000 to 180,000 job-years of employment in California, including 4,000 permanent operations and maintenance jobs.
• Port upgrades are critical for floating offshore wind because platforms are assembled on shore and towed out. For example, the Port of Humboldt Bay requires a total of $130-$310 million for upgrades and $50-$100 million for floating platform fabrication, despite an initial $10.5 million grant from the California Energy Commission.
• Research indicates that West Coast offshore wind generates power when the grid needs it most, specifically in the early evening. Installing 50,000 MW off California's coast by 2045—representing 25 percent of the technical potential—could provide up to 40 percent of the state's total electricity in a net-zero grid.
• Floating offshore wind is necessary for the West Coast due to deeper waters. The U.S. Department of Energy predicts costs will drop from approximately $160/MWh in 2020 to between $60 and $105/MWh by 2030, with California expected to be at the lower end of that range.
• Transmission costs for offshore wind are estimated between $0.75 and 2.5 billion per GW of installed capacity. The authors suggest a subsea cable linking production along the entire West Coast to increase resilience against wildfires and share resources.
