February 29: The most recent update to this tracker adds legislation introduced in Oregon that would declare a state of emergency regarding offshore wind's labor, environmental and other impacts, and require the development of a roadmap to curb those impacts. Also new is legislation in Massachusetts directing the Executive Office of Energy and Environmental Affairs to establish an advisory council on offshore wind wildlife habitat management.

Other recent developments in the offshore wind industry include:

An offshore wind boom is underway in the U.S. as the industry aims to meet the Biden administration’s goal of deploying 30 GW by 2030. Last year the Bureau of Ocean Energy Management held its first-ever auction for offshore wind leases off the West Coast in addition to auctioning six new lease areas in the New York Bight, and the Bureau of Ocean Energy Management held its first-ever auction for offshore wind leases off the West Coast. A record total of nine leases went into effect in 2022.

The federal government has also proposed lease sales in the Gulf of Maine and the Gulf of Mexico, where deeper waters will necessitate the use of floating wind platforms instead of fixed-bottom turbine foundations. And Ohio is working to establish an offshore wind farm in Lake Erie that would be the first U.S. freshwater farm in state-controlled waters.

Offshore wind farms are concentrated in the Northeast's shallow waters

Hover over each dot to see the capacity, status and developers of each wind farm under construction on the East Coast and in the Great Lakes.

Offshore wind projects under construction are poised to add unprecedented capacity to the nascent industry

Estimated completion dates for offshore wind farms under construction range from 2023 to 2028. These 14 farms are expected to add 14,852 MW of capacity.

As the industry expands, so do the number of state and federal policy measures aimed at managing offshore wind. These measures include proposals to direct some offshore wind revenue toward studies on the industry’s marine impacts, and ones that would require analysis of offshore wind’s impacts on transmission planning. Use the search field below to find individual states by their postal abbreviation, or type "US" to find activity at the federal level.

States and Congress are considering a bevy of measures

As the sector grows, legislators and regulators are working to address economic, logistical and environmental challenges
