The U.S. Department of Energy (DOE), in partnership with the U.S. Department of the Interior’s (DOI) Bureau of Ocean Energy Management (BOEM), was developing strategic offshore wind (OSW) transmission planning to allow wind resources to be captured off the coasts of the United States and delivered to communities as reliable power.
Past Activities
Action Plan for Offshore Wind Transmission Development in the U.S. West Coast Region:
In January 2025, the Grid Deployment Office, in partnership with BOEM, released the Action Plan for Offshore Wind Transmission Development in the U.S. West Coast Region (Action Plan) to address OSW transmission challenges on the U.S. West Coast. The Action Plan provided recommendations on how to connect the first generation of West Coast offshore wind projects to the Western electric grid and support transmission over the next several decades.
West Coast Offshore Wind Transmission Convening Series: Throughout 2024, DOE and BOEM led a series of 12 workshops to develop a set of recommendations for addressing OSW transmission challenges along the West Coast. This targeted engagement process sought input from Tribal Nations, federal and state agencies, cable and transmission providers, fisheries organizations, non-governmental organizations, developers, unions, utilities, and other ocean co-users and interested parties to discuss the aspects of transmission planning which are most meaningful and applicable to them.
The Convening Series was complemented by a Request for Information (RFI) in August 2024 to allow individuals and organizations to submit written input about transmission topics, including siting, technology, and policy considerations. RFI responses were considered as the recommendations were prepared.
West Coast Offshore Wind Transmission Literature Review and Gaps Analysis: In February 2023, DOE’s Wind Energy Technologies Office released the West Coast Offshore Wind Transmission Literature Review and Gaps Analysis. This analysis reviewed existing literature focusing on the technical evaluation of offshore wind energy transmission through potential points of interconnection located along the coastlines of California, Oregon, and Washington. The study took into consideration existing and emerging state policies and Bureau of Ocean Energy Management wind site lease activities.
West Coast Offshore Wind Transmission Study: Pacific Northwest National Laboratory and National Renewable Energy Laboratory conducted a two-year study to investigate the potential of floating OSW to lower energy costs and enhance the resilience of the nation’s western grid. The West Coast Offshore Wind Transmission Study, funded by DOE's Grid Deployment Office and co-managed by Wind Energy Technology Office, released its report on January 15, 2025.
