US offshore wind 2026: the post-cancellation rebuild and what got reset
US offshore wind faced major setbacks in 2023-2024 with multiple project cancellations (Ørsted Ocean Wind, Avangrid Park City, others) over cost overruns and PPA mismatches. By Q1 2026, 4 GW operational (Vineyard Wind 1, South Fork, Revolution Wind partial), 5 GW under construction. New project rebids at $130-160/MWh tariffs. This deep-dive covers what got cancelled and why, the rebuild mechanism, supply chain + political risks, and the realistic 2030 outlook.

1. The US offshore wind rollercoaster
US offshore wind has been one of the most volatile renewable stories of the decade. Hyped as a multi-hundred-billion-dollar industry that would decarbonize the populous East Coast, it crashed into cost inflation + fixed-price contracts in 2023-2024, suffered a wave of cancellations, then began a fragile rebuild on more realistic economics.
For developers, investors, and policymakers, the US offshore wind saga is a cautionary tale about contract structure, cost-inflation risk, and political durability — with lessons relevant to offshore wind markets worldwide.
2. Where US offshore wind stands in 2026
US installed + under-construction offshore wind (Q1 2026):
Operational + commissioning (~4 GW):
- Block Island (2017): 30 MW (the pioneer pilot)
- Vineyard Wind 1 (late 2024): 800 MW
- South Fork Wind (2024): 132 MW
- Revolution Wind (2025-2026, partial): 700 MW
- Coastal Virginia Offshore Wind (2026, phased): 2,587 MW
Under construction (~5 GW, commissioning 2026-2028):
- Sunrise Wind (NY): 924 MW
- Empire Wind 1 (NY): 810 MW
- Ocean Wind 2 (NJ, restarted): 1.1 GW
- Plus several smaller projects
The federal target of 30 GW by 2030 looks increasingly unrealistic — more like 15-20 GW operational by 2030 is the realistic outcome.
3. The 2023-2024 cancellation wave
The industry's near-death experience. Major projects cancelled:
- Ørsted Ocean Wind 1 + 2 (NJ): cancelled Oct 2023, ~2 GW lost — Ørsted took a multi-billion-dollar writedown
- Avangrid Park City Wind (CT): cancelled 2023
- Equinor Empire Wind 2 (NY): cancelled, later partially restarted
- Shell + EDF Atlantic Shores (NJ): cancelled
- Multiple smaller projects
Combined, 6+ GW of announced capacity evaporated in 2023-2024 — a genuine industry crisis that called the entire US offshore wind thesis into question.
4. Why projects cancelled — three converging factors
Cost inflation
Steel, copper, vessels, and labor all rose 30-50% during 2021-2023. Projects bid at 2019-2021 prices became deeply unprofitable at 2023 costs. Offshore wind is especially exposed — it's steel-and-vessel-intensive.
Fixed-price PPAs
The fatal flaw. Most US offshore PPAs were fixed-price with no inflation adjustment. When costs blew out, developers couldn't pass the increases through. The contracts that looked attractive in 2019 became loss-makers by 2023, forcing cancellations + renegotiations.
Interest rate increases
Offshore wind is extremely capital-intensive with long payback. The Fed's 2022-2023 rate increases sharply raised financing costs, further crushing project economics that were already squeezed by cost inflation.
5. The rebuild — rebid mechanism + indexed PPAs
By 2024-2026, the industry restructured to address the failures:
Rebid mechanism
States created processes for developers to cancel underwater projects and rebid at higher tariffs reflecting cost reality:
- Ocean Wind cancelled → restarted as Ocean Wind 2 at higher tariff
- Empire Wind 2 cancelled → restarted at higher tariff
- Several projects rebid through new state solicitations
Indexed PPAs
The crucial structural fix. New PPAs include inflation-indexing for steel, copper, and labor categories — so cost increases pass through rather than crushing developer margins. This reduces developer risk + makes projects financeable.
Higher tariffs
New US offshore wind PPAs (NY, NJ, MA, RI, CT, ME) range $130-160/MWh — substantially above the $80-110/MWh of the cancelled projects. The higher tariffs reflect real costs, making projects viable but raising electricity costs for ratepayers.
6. Supply chain constraints
Beyond cost, US offshore wind faces structural supply chain bottlenecks:
Installation vessels
US Jones Act requires US-flagged vessels for US offshore operations. The US-flagged offshore wind installation vessel fleet is tiny — creating scheduling contention + cost. The first purpose-built US Jones Act wind installation vessel (Charybdis) faced delays.
Port infrastructure
New Jersey, Virginia, Maryland, Massachusetts building dedicated offshore wind ports for assembly + staging. These investments are catching up but lagged early project needs.
Domestic content
Rising domestic content requirements (IRA bonus credits) push for US-made components, but the US offshore wind supply chain is nascent — most components still imported.
7. Political risk — the wildcard
US offshore wind faces persistent, bipartisan-variable political risk:
- The Trump administration is explicitly hostile to offshore wind, creating federal permitting + leasing uncertainty
- Local opposition in some coastal communities (viewshed, fishing industry concerns)
- Federal vs state authority tensions
- Litigation over environmental reviews
This political risk is unique among major renewable technologies — solar + onshore wind + storage face less federal hostility. Offshore wind's dependence on federal waters (BOEM leasing + permitting) makes it especially exposed to administration changes.
8. State-by-state picture
US offshore wind is driven by state-level procurement (states sign the PPAs):
- New York: most aggressive; Sunrise Wind + Empire Wind 1 under construction; ambitious targets
- New Jersey: recovered from Ørsted cancellation; Ocean Wind 2 restarted
- Massachusetts: Vineyard Wind operational; continued procurement
- Virginia: Coastal Virginia Offshore Wind (Dominion) — largest US project, phased commissioning
- Connecticut, Rhode Island, Maryland, Maine: smaller but active
State commitment + ratepayer willingness to absorb higher tariffs is what sustains the industry through federal political headwinds.
9. Lessons for global offshore wind
The US experience offers lessons relevant worldwide (including India's emerging offshore wind program):
- Never use fixed-price PPAs without inflation indexing — the single biggest US mistake
- Build supply chain + ports before project pipeline — vessel + port constraints delayed + raised costs
- Political durability matters — offshore wind's federal-permitting dependence makes it politically exposed
- Realistic cost assumptions — the early US tariffs were unrealistically low for actual offshore construction costs
India's offshore wind tenders (5+ GW pipeline) should heed these lessons — index PPAs, build port + vessel capacity, set realistic tariffs.
10. Realistic 2030 outlook
The federal 30 GW by 2030 target is widely viewed as unachievable now. Realistic outcome:
- 15-20 GW operational by 2030
- Indexed PPAs at $130-160/MWh making new projects viable but expensive
- Continued state-driven procurement despite federal headwinds
- Supply chain + ports maturing through 2027-2028
US offshore wind will be a real but smaller-than-hoped industry — meaningful for East Coast decarbonization but not the runaway success early projections imagined.
11. What to watch next
Three signals:
-
First post-rebid project commissioning (likely Sunrise Wind or restarted Empire Wind 1, 2027) — does the indexed-PPA model actually deliver viable IRRs? If yes, the industry returns to growth. If projects struggle again, further reset needed.
-
Federal permitting under the current administration — whether offshore wind leasing + permitting continues or stalls. The biggest swing factor.
-
Charybdis + US vessel fleet — whether domestic installation vessel capacity materializes, easing the Jones Act bottleneck.
Bottom line: US offshore wind crashed on fixed-price PPAs + cost inflation in 2023-2024, losing 6+ GW to cancellations. It's rebuilding on indexed PPAs at higher tariffs ($130-160/MWh), with ~4 GW operational + 5 GW under construction. The realistic 2030 outcome is 15-20 GW (not the 30 GW target). Political risk + supply chain constraints remain the key uncertainties. The episode is a cautionary tale every offshore wind market — including India — should learn from.
