US regulators have started to re-evaluate rules underpinning approvals for offshore wind projects, as President Donald Trump's administration continues to push for an end to "preferential treatment" for renewable generation.
The US Interior Department on Thursday said it is beginning a "full review" of federal offshore wind regulations to ensure they align with both federal law and energy policies promoted by Trump, who has openly scorned wind and solar projects.
Two agencies within Interior, the Bureau of Ocean Energy Management and Bureau of Safety and Environmental Enforcement, will spearhead the inquiries. The agencies will consider updating rules pertaining to renewable energy under the Outer Continental Shelf Lands Act, a 1953 law that outlines Interior's authority to lease areas in federal waters.
The new regulatory scrutiny is the latest step in the administration's broader push to end what it calls "favoritism" shown to wind and solar farms, part of a broader agenda that has marginalized renewables and chilled the US offshore wind sector. Trump in January placed a moratorium on new offshore wind leasing, and Interior last month rescinded all offshore wind lease areas.
"The department is fully committed to making sure that offshore energy development reflects President Trump's America First Energy Dominance agenda and the real-world demands of today's global energy landscape," US interior secretary Doug Burgum said.
Thursday's announcement is also the latest in a recent blitz of actions from Interior targeting renewable energy development. Burgum on 1 August directed the agency to prioritize a project's "capacity density" when considering approvals of new generation on federal lands, questioning whether permitting wind and solar farms is legal at a foundational level given their "disproportionate land use" when "reasonable" alternatives, such as nuclear, coal and natural gas facilities, are "technically and economically feasible".
Capacity density measures a project's capacity and capacity factor, or expected output, relative to its total acreage. This puts intermittent wind and solar farms at an inherent disadvantage to traditional thermal generators, which take up much less physical space.
Interior is not the only agency that has recently placed the wind sector in its crosshairs. The US Department of Transportation late last month launched a study to "inform safety guidelines" for wind turbines near infrastructure that uses systems reliant on radio frequencies, while recommending a minimum 1.2-mile setback for wind turbines from highways and railroads. In addition, the Federal Aviation Administration will "thoroughly evaluate" proposed wind farms to ensure they do not pose a danger to aviation — including hypothetical, emergent technologies such as automated aircraft.
