The purpose of this web page is to describe the status of and provide access to more information for individual offshore wind energy projects from Maine to northern North Carolina, using publicly available resources.

The U.S. Bureau of Ocean Energy Management (BOEM) is the lead federal agency authorized to issue leases, easements, and rights of way to allow for renewable energy development on the Outer Continental Shelf (OCS). BOEM describes four distinct phases of their renewable energy program: planning, leasing, site assessment, and construction and operations, with stakeholders being engaged throughout the process. For more detail about these phases, see BOEM’s page on Renewable Energy Regulatory Framework and Guidelines. Other entities, including states, also have roles in the development and permitting process, which is beyond the scope of this web page.

1. Planning & Analysis (~2 years)

The first phase involves planning and analysis to identify the most appropriate sites for renewable energy leasing and development activities. This phase involves federally recognized tribes, other federal agencies, states, local governments, and includes mechanisms for public input. Steps in this phase could include:

  • Intergovernmental Task Force
  • Request for Information or Call for Information and Nominations
  • Area Identification. This can include unsolicited bids.
  • Environmental Reviews
2. Leasing (~1-2 years)

The Energy Policy Act of 2005 requires that BOEM issue leases and grants on a competitive basis, unless it determines that there is no competitive interest in the proposed lease or grant. When only one developer has indicated interest in developing a given site, BOEM may issue a lease or grant noncompetitively. If multiple developers express interest in leasing a given site, then BOEM proceeds with a competitive leasing process, which may ultimately result in a lease sale or auction. In either case, there are multiple opportunities for public involvement in the activities in this phase. In practice, all leases issued in the Northeast have been competitive.

  • Publish leasing notices
  • Conduct auction or negotiate lease terms
  • Issue lease(s)

3. Site Assessment (up to 5 years)

Once a lease or grant is issued, lessees have 12 months to submit a Site Assessment Plan (SAP) to BOEM that describes how they will characterize the area (e.g., conduct resource assessments, install meteorological towers or buoys). SAPs pertain to the entire lease area. After site assessment, developers often publicly announce their intent to build a project within the lease area and choose a project name. At this time, they might also begin negotiating with utility companies, states, and other entities to secure support for the project.

  • Site characterization
  • Site assessment plan
4. Construction & Operations (~2 years) (+25)

This phase includes the formal submission of a plan to construct a specific offshore wind energy facility within a lease area, the environmental review of the proposed project by BOEM with cooperating and participating agencies (includes federal and state) under the National Environmental Policy Act (NEPA), and the actual construction of a facility. This phase includes several steps that span many years and include public meetings and comment periods (*indicates formal public comment opportunity):

  1. Developer submits Construction and Operations Plan (COP)
    After BOEM approves the COP (between steps A & B), maps showing the proposed footprint and potential layout of the project will become available on the Northeast Ocean Data Portal.
  2. BOEM publishes a Notice of Intent to prepare an Environmental Impact Statement (*)
    When a project reaches this stage, a project-specific web page will become available on the Northeast Ocean Data Portal.
  3. BOEM issues a Draft Environmental Impact Statement(*)
  4. BOEM issues a Final Environmental Impact Statement
  5. BOEM issues a Record of Decision
  6. Construction
  7. Operation
  8. Decommissioning
