Offshore Wind Development in North America: Market Landscape
North America's offshore wind sector has entered a pivotal phase. As of early 2026, the U.S. has three operating offshore wind farms — Block Island (30 MW), South Fork Wind (132 MW), and Vineyard Wind 1 (806 MW, partially operational) — with five more projects under active construction. Canada, meanwhile, is laying the regulatory groundwork for its first projects off Nova Scotia and Newfoundland.
Key Developers and Their Portfolios
The market is dominated by European energy majors with deep offshore experience, partnered with U.S. utilities and infrastructure investors:
| Developer | Active U.S. Lease Areas | Combined Pipeline |
|---|---|---|
| Ørsted | Revolution Wind, Sunrise Wind | ~4 GW |
| Equinor | Empire Wind, Beacon Wind | ~3.3 GW |
| Avangrid/CIP | Vineyard Wind, New England Wind | ~2.4 GW |
| Dominion Energy | CVOW | 2.6 GW |
| EDF / Atlantic Shores | Atlantic Shores South | ~2.8 GW |
| US Wind | Maryland Offshore Wind | 1.7 GW |
| TotalEnergies | New York Bight OCS-A 0538 | ~3 GW |
| RWE / National Grid | Community Offshore Wind | ~3.2 GW |
Regional Hubs
- U.S. Northeast (MA, RI, CT, NY)
- Densest concentration of leases and the majority of operational and under-construction projects. Vineyard Wind and Revolution Wind are milestones for the region.
- U.S. Mid-Atlantic (NJ, MD, VA)
- Atlantic Shores, US Wind MarWin, and Dominion's CVOW represent significant pipeline. Virginia's CVOW at 2.6 GW is the largest single project in the U.S.
- U.S. Gulf of Mexico & Pacific
- Emerging areas with lease sales completed off Louisiana and California. RWE's Canopy project targets ~1.6 GW of floating wind off Northern California.
- Canada (Nova Scotia, Newfoundland)
- Nova Scotia has designated four areas for up to 5 GW of offshore wind licensing. First lease bids expected in 2026.
Supply Chain Implications
The combined U.S. pipeline exceeds 40 GW of planned capacity. For subcontractors and vessel operators, this translates to demand for monopile foundations, subsea cables (inter-array and export), installation vessels (WTIVs), crew transfer vessels, and O&M contracts spanning decades. Jones Act compliance requirements create specific opportunities for U.S.-flagged vessel operators.
Regulatory and Political Headwinds
In late 2025, the U.S. Interior Department issued stop-work orders and lease suspensions for five offshore wind projects, citing national security reviews. By January 2026, federal courts had granted preliminary injunctions allowing several projects — including Revolution Wind and CVOW — to resume construction. The regulatory uncertainty has caused some European developers, notably RWE, to pause new U.S. investments pending policy clarity.
