The US Department of Transportation has given a $427m grant to a port and power project in northern California.
The money will pay for a terminal at Humboldt Bay, a recreation and conservation area.
The terminal will be used for the assembly and transport of floating offshore wind turbines.
A video setting out the plan can be seen here.
The money is being disbursed under the department’s Nationally Significant Multimodal Freight & Highway Projects programme.
It is conditional on Humboldt Bay raising matching investment from the private sector.
The scheme is in line with US government targets that call for at least 5GW of power to be generated off the coast of California by 2030 and 25GWs by 2045.
The national target is 30GW by 2030 and 110GW by 2050.
According to local media, the terminal will be able to handle the assembly and deployment of one 25MW turbine a week.
The grant includes $51m towards environmental restoration and $10m for a solar farm to power the terminal.
There will also be $6m for facilities for local First Nation people, fishermen and nearby residents.
The Offshore Wind Heavy Lift Marine Terminal Project is in the planning and design phases.
Approval for the first phase of the scheme will be sought next year and the completion of the design will take place in 2026.
