US Wind Offshore Energy Project: Key Permits, Approvals, and Environmental Impact in Delaware

The US Wind Project is a proposed offshore wind energy development off the coast of Maryland, with significant implications for Delaware’s environmental landscape. The project involves the construction of up to 121 wind turbine generators, offshore substations, and up to four offshore/onshore export cables, which will bring the generated power ashore at 3Rs Beach in Delaware Seashore State Park. The electricity will be transmitted to a proposed substation near the Indian River Power Plant in Sussex County.

Key details of the project include:

Permitting Process and Public Engagement:

• Federal and State Permits: The offshore turbines require federal permitting, while bringing power lines ashore and constructing infrastructure in Delaware involves state-level permits from the Delaware Department of Natural Resources and Environmental Control (DNREC).

• Public Information Sessions: DNREC hosted a public information session on June 5, 2024, in Lewes, with a virtual public hearing on July 9, 2024, to address the necessary permits for the project.

• Secretary’s Orders and Approvals:

  • On Dec. 9, 2024, DNREC approved the issuance of various permits, including the Subaqueous Lands Permit, Wetlands Permit, and Coastal Construction Permit.

  • Final approvals for the necessary permits were issued in January 2025.

Project Components:

• Offshore Wind Turbines: The project will include up to 121 wind turbines spread across a designated lease area off the coast of Maryland (Lease OCS-A 0490).

• Export Cables and Substation: Portions of the export cables will cross Delaware state waters and connect to a substation near the Indian River Power Plant. This project also includes the construction of four transition vaults in the 3Rs Beach parking lot.

• Environmental Impact: The project is expected to impact state-regulated subaqueous lands and tidal wetlands in Delaware, particularly during the construction phase involving dredging and trenching activities.

Final Approvals and Requirements:

• Permits Issued:

  • Subaqueous Lands Permit and Lease (Jan. 8, 2025)

  • Wetlands Permit (Jan. 8, 2025)

  • Coastal Construction Permit (Jan. 10, 2025)

• Water Quality Certification: Approval for dredging within the Indian River, a key part of the infrastructure development, was granted on Oct. 18, 2024.

Next Steps:

The project is now moving toward construction following the final permits and approvals. The focus will shift to the implementation phase, including laying cables, constructing transition vaults, and establishing the offshore wind infrastructure. As the project progresses, additional oversight will ensure minimal environmental disruption, especially concerning sedimentation in the Indian River and Indian River Bay.

The US Wind Project is poised to be a transformative addition to the region’s renewable energy resources. It is important for Delaware residents and stakeholders to stay informed as further development and construction unfold, ensuring the careful management of the area’s natural resources and public lands.
