The Northeast Offshore Wind Regional Market Characterization report identifies the opportunities and challenges that will shape the offshore wind market. It estimates the scale of potential offshore wind deployment to serve Northeast markets through 2030, given the nature of the offshore wind resource, federal lease opportunities, state policies, regional energy needs, existing electricity generation and planned retirements, and transmission capacity. The report finds that a low regional deployment trajectory could lead to 4,000 megawatts of offshore wind generation by 2030 off the Atlantic coast of the Northeast. A high regional deployment trajectory could lead to nearly 8,000 megawatts, which could power almost four million homes. The report also provides background information on topics ranging from interconnection infrastructure and permitting timelines to electricity markets and relevant public policies.
