Offshore Wind Update: Court of Chancery Rules on SB 159

There have been several important developments in the ongoing offshore wind proceedings affecting Delaware, with activity now unfolding across three separate legal tracks.

Court of Chancery Rules on SB 159

On March 16, 2026, arguments were heard in Delaware’s Court of Chancery regarding SB 159 in a lawsuit brought by Sussex County Council and the City of Fenwick Island. On March 25, 2026, the Court announced its decision through legal counsel, finding that the City of Fenwick Island did not have standing. The remaining plaintiff, Sussex County Council, lost on the merits, with the Court holding that the Delaware General Assembly acted within its constitutional authority in passing SB 159, thereby overriding Sussex County’s denial of the permit required to allow a substation at 3Rs Beach.

Sussex County Council may appeal this decision to Delaware Superior Court. However, as it stands, the ruling clears a key legal obstacle and does not preclude US Wind from proceeding with plans to bring underwater transmission cables ashore at 3Rs Beach.

DNREC Permits Under Challenge

Separate from the SB 159 case, the Caesar Rodney Institute and other appellants continue to challenge DNREC’s approval of permits related to the US Wind project before the Delaware Environmental Appeals Board. This appeal centers on whether DNREC followed proper legal procedures, including concerns that multiple permits were combined into a single process, limiting meaningful public input and raising questions about whether approvals were granted prematurely.

Oral argument in the beach construction permit case is scheduled for May 14 at 9:30 AM in Superior Court in Sussex County. Separately, a broader challenge to DNREC’s permitting decisions—brought by the Caesar Rodney Institute along with other appellants including local residents and organizations—is moving forward before the Environmental Appeals Board. In addition, a separate appeal filed by Edward Bintz challenges the project’s “Consistency Determination,” which is a required finding under federal and state coastal law that the project complies with Delaware’s coastal management policies. A hearing in that case was originally scheduled for March 10 but has been postponed, with a new date pending. This means that, beyond the court case and general permit challenges, the project must still independently demonstrate that its construction and operations are consistent with Delaware’s coastal protections.

Federal Litigation and Broader Context

In parallel, the Ocean City litigation against US Wind, with the Caesar Rodney Institute as an additional appellant, appears to be moving toward arguments in late spring or early summer, though no firm updates have been reported.

At the same time, broader warning signs are emerging across the offshore wind industry. TotalEnergies recently reached an agreement with the U.S. Department of the Interior to relinquish two offshore wind lease areas off New York and North Carolina in exchange for reimbursement of nearly $1 billion in prior lease payments, redirecting that capital into oil and natural gas projects. Rather than moving forward with development, a major global energy company chose to exit its offshore wind position and reallocate investment into more reliable energy sources. The agreement underscores the degree to which offshore wind development remains dependent on government policy and subsidies—and how quickly projects can shift when those conditions change.

Additionally, Apollo Global Management, a major backer of US Wind, is currently facing a lawsuit alleging it concealed business ties with Jeffrey Epstein from shareholders. While separate from the permitting process, this adds another layer of scrutiny around the project’s financial backing.

Federal Subsidy Deadline Creates New Pressure

Beyond the legal challenges, US Wind now faces a critical federal requirement.

To qualify for key federal subsidies, the project off the coast of Delaware and Maryland must demonstrate that at least 5% of construction is completed by early summer. This introduces a significant timing challenge.

Even with the Court of Chancery ruling allowing progress at 3Rs Beach, major permitting issues remain unresolved, and offshore wind construction involves complex, large-scale infrastructure that cannot be rapidly accelerated. While construction of an onshore substation at 3Rs Beach may be more feasible in the near term—and could potentially count toward the 5% threshold—it remains uncertain whether that alone would be sufficient to meet federal requirements.

The issue is no longer just whether the project can proceed legally in Delaware—it can—but whether it can proceed quickly enough to meet federal deadlines.

Three Fronts, One Timeline

Three separate legal tracks remain in play: the SB 159 ruling in Chancery Court—which may be appealed by Sussex County Council—ongoing DNREC permit challenges, and federal litigation involving Ocean City.

While the Chancery decision strengthens US Wind’s position by affirming the state’s authority to override local zoning, it does not resolve the broader permitting and legal landscape.

At the same time, the requirement to demonstrate 5% construction by early summer introduces a new constraint.

Taken together, US Wind has prevailed on one front, but the project continues to face pressure from two remaining legal challenges—and from the clock.
