California is moving to sue the federal government over the cancellation of a major offshore wind project, escalating a dispute between the nation's most populous state and an administration that has worked aggressively to unwind the U.S. wind sector.

State Attorney General Rob Bonta and the California Energy Commission on June 23 issued a notice of intent to sue the Trump administration over an Interior Department arrangement that ends development of Golden State Wind, a floating offshore project planned off the central coast near Morro Bay, the Associated Press reported. The filing opens a 60-day window for the administration to address the state's concerns before litigation begins.

The project and the deal

Golden State Wind is a roughly 2-gigawatt project that backers said could supply electricity to about 1.1 million homes. It is a joint venture between Ocean Winds and the Canada Pension Plan Investment Board, according to E&E News.

Floating offshore wind differs from conventional offshore turbines fixed to the seabed. Off California, ocean depths drop sharply close to shore, so turbines must sit on floating platforms anchored by mooring lines, allowing development in deep water. Such projects require a federal lease from the Interior Department, followed by years of survey work, environmental review and permitting before construction.

Rather than let that process continue, Interior reached an agreement under which Golden State Wind can recover about $120 million in lease fees — but only on the condition that the company invests an equal amount in oil and gas assets, energy infrastructure or LNG projects along the Gulf Coast, the Associated Press reported.

California's argument

Bonta and state energy officials contend Interior illegally reallocated federal funds to pay a developer to walk away from a clean-energy lease and channel the money into out-of-state fossil-fuel projects, in what the state says is an unlawful agreement that violates the Outer Continental Shelf Lands Act. The state also says it has already spent more than $100 million preparing ports, transmission and supply chains for offshore wind, investments now at risk, E&E News reported.

"California won't stand idly by as the Trump Administration illegally strikes deals to kill offshore wind projects and replace them with more windfalls for his fossil fuel friends," Bonta said. State officials say the cancellation undermines California's clean-energy goals; the state is targeting 25 gigawatts of offshore wind by 2045.

Broader context

The Golden State Wind deal is part of a wider pattern. Offshore wind projects accounting for about $2.6 billion in buyout agreements have been halted under the administration, which has explicitly prioritized fossil-fuel development over renewables, Engineering News-Record reported. The administration has defended its broader approach as restoring oil and gas leasing and ending what it casts as costly subsidies for wind.

The dispute now enters a 60-day clock. If Interior does not resolve the state's objections, California has signaled it will take the matter to court — a test of how far the federal government can go in paying developers to abandon energy leases.
