New Hampshire’s Offshore Wind Policy Shift: A 2025 Overview
Granite State Report – Deep Dive
By the Granite State Report research desk
Executive Summary
In 2025, New Hampshire executed a decisive about-face on offshore wind. After several years of tentative exploration under former Gov. Chris Sununu—including a 2019 executive order to prepare the state for Gulf of Maine leasing—the new administration of Gov. Kelly Ayotte and the Republican-led Legislature dismantled the state’s offshore-wind posture. The Legislature passed HB 682 (signed Aug. 1, 2025; effective Sept. 30, 2025), eliminating New Hampshire’s Office of Offshore Wind Industry Development, the Offshore and Port Development Commission, and related workforce and planning bodies, while retitling the remaining agency functions under a generic Office of Energy Innovation. In parallel, the federal policy environment shifted: the Trump administration (beginning Jan. 20, 2025) withdrew wind areas on the U.S. Outer Continental Shelf, including the Gulf of Maine, erasing BOEM’s planned leasing pathway that, as of 2024, had slated two sales (one in October 2024 and another in 2028). Together, these moves effectively shelved New Hampshire’s near-term prospects to participate in the region’s floating offshore-wind economy.
This report unpacks how we got here, what changed in 2025, how the shift compares with neighboring states, and what it means for ratepayers, ports, fisheries, grid planning, and climate goals.
1) A Short History of New Hampshire’s Offshore-Wind Posture (2019–2024)
2019–2020: Laying groundwork, cautiously.
Gov. Sununu requested federal coordination for Gulf of Maine offshore wind and signed an executive order creating four advisory committees (environmental, fisheries, port & infrastructure, markets & transmission) to prepare for BOEM’s process. Even then, New Hampshire positioned itself as a low-commitment participant relative to Massachusetts and Maine.
2021–2024: BOEM planning accelerates; NH stays on the sidelines.
BOEM carved out a Gulf of Maine planning area, held task-force meetings, and by April 2024 published a five-year leasing schedule listing two anticipated Gulf of Maine sales—first in October 2024, second in 2028. Maine, meanwhile, advanced a floating-wind research array (up to 12 turbines/144 MW) and selected Sears Island for a specialized port to build floating platforms. New Hampshire monitored but made no anchor investments in ports or supply chain.
Regional contrast, pre-2025.
Maine and Massachusetts articulated clear procurement and port strategies; New Hampshire’s steps remained advisory and exploratory, with Sununu’s broader record on clean energy often described as hands-off—occasionally supportive of incremental changes but skeptical of mandates.
2) The 2025 Pivot: What Changed in Concord
Legislation: HB 682 and related measures.
In February 2025, the NH House passed updates to state energy policy that removed offshore wind from focus, prioritized “market-driven” energy approaches, and advanced HB 682 to repeal/retitle offshore-wind entities across the Department of Energy. By summer, HB 682 was signed by Gov. Kelly Ayotte as Chapter 286 (Aug. 1, 2025), with an effective date of Sept. 30, 2025. The law eliminates the Office of Offshore Wind Industry Development, repeals the offshore wind workforce training center committee, and abolishes the offshore and port development commission—folding residual functions into the Office of Energy Innovation.
Agency retitling and mission shift.
Following the law, New Hampshire formally erased “offshore wind” from the state energy office’s title and remit. Local outlets reported the state would no longer dedicate staff or resources specifically to advance offshore wind readiness.
Narrative from leadership.
Supporters framed the move as a ratepayer-first correction, citing concerns over costs, grid integration, defense/fisheries conflicts, and federal reversals—arguing New Hampshire should not “chase” a volatile national market. Opponents warned that NH is locking itself out of a regional industry that surrounding states will continue to shape and benefit from. (These positions are reflected across legislative debates and coverage.)
Symbolic resolution.
In parallel, a House concurrent resolution (HCR 4) explicitly called for rejecting offshore wind projects in and around New Hampshire’s waters until impacts on ecosystems, fisheries and ratepayers are better understood. While non-binding, it signaled political alignment with a broader pullback.
3) The Federal Whiplash: BOEM’s Gulf of Maine Plan vs. 2025 Rollbacks
BOEM’s 2024 plan (before reversal).
As of April 24, 2024, BOEM expected two Gulf of Maine sales (2024 and 2028). The region is deep-water, requiring floating wind platforms—an area where Maine (with the University of Maine’s technology) sought to lead.
2025 federal rollback.
Beginning Jan. 20, 2025, the Trump administration withdrew wind-energy areas on the Outer Continental Shelf through executive action, and by July 31, 2025, federal regulators had eliminated the Gulf of Maine wind power zone—wiping BOEM’s two-million-acre area that spanned offshore Maine, New Hampshire, and Massachusetts. Harvard Law’s policy tracker summarizes the sequence of federal actions; Maine Public reported the Gulf of Maine erasure specifically.
Implications for New Hampshire.
Even if New Hampshire had stayed the course, the federal step-back would have stalled commercial leasing timelines in the near term. But NH’s choice to dismantle state capacity means it will be slower to re-engage if/when federal policy reopens Gulf of Maine leasing.
4) Why New Hampshire Reversed: The Stated (and Unstated) Drivers
- Cost and Ratepayer Risk Supporters of the 2025 pivot pointed to rising costs in northeastern offshore wind procurements, contract terminations, and inflationary pressures, suggesting NH should avoid binding commitments. The Legislature’s new energy-policy framing emphasized market-driven, affordable resources.
- Federal Uncertainty & National Security Narratives With OCS areas withdrawn and projects elsewhere challenged or halted, the state’s leadership argued it was prudent to pause. (Separately, litigation around Revolution Wind in Rhode Island dramatized federal-project tensions in 2025.)
- Fisheries & Environmental Considerations HCR 4 explicitly cites ecosystem and fishing-industry concerns—a theme long present in Gulf of Maine debates, including from lobstering groups. Maine’s own efforts have faced vigorous fisheries pushback.
- Defense/Maritime Conflicts The Gulf of Maine hosts Navy and NOAA operations; coordination complexities have featured in federal reviews more generally. State leaders raised the use-conflict risk profile when arguing for retrenchment. (This is consistent with broader BOEM scoping discussions.)
- Opportunity Cost & Focus By recentering staff time into a generalized Office of Energy Innovation, Concord signaled a preference to prioritize near-term reliability and affordability debates (e.g., transmission constraints, heating fuels, demand-side measures) rather than a long-cycle OSW industry bet.
5) What New Hampshire Gave Up (At Least For Now)
Ports & Manufacturing
Floating offshore wind requires large assembly yards, deepwater quays, and specialized logistics. Maine moved to designate Sears Island for a purpose-built port; Massachusetts has New Bedford as a fixed-bottom hub and is investing further. NH’s pullback means no near-term port play and a tougher climb to land tier-1 suppliers once the market reopens.
Workforce & R&D Spillovers
UMaine’s research array (12 turbines, 144 MW) aims to anchor a floating-wind learning curve in the region. Without targeted NH programs (repealed in HB 682), in-state colleges and trades lose a dedicated on-ramp to OSW training dollars and internships.
Grid-Planning Influence
OSW entails offshore-onshore transmission planning (shared “backbone” lines, coastal interconnections). With NH stepping back, Massachusetts and Maine will more heavily shape regional interconnection concepts—potentially sidelining NH’s preferences for landing points and grid upgrades.
Long-Run Clean-Energy Optionality
If the Gulf of Maine reopens later this decade, states with standing procurement pathways and prepared ports/workforces will move first. NH’s pause preserves today’s budget but risks being last in line for long-run price declines and local content.
6) Neighboring States: The Counterfactual
Maine: All-in on Floating
Maine secured a federal research lease in 2024, advanced Sears Island as a wind port in 2024–2025, and continues to message a 2040 goal for substantial OSW supply (about half of statewide electricity by 2040). Political contention is real (notably from fisheries), but the state remains a first mover in floating-platform know-how.
Massachusetts: Procurement Engine
Massachusetts continues to steer large solicitations and transmission strategy despite industry turbulence. New Bedford remains the East Coast’s emblematic OSW port for fixed-bottom projects, with eyes on adapting to floating components in the 2030s. (Context in BOEM regional planning records.)
New Hampshire: Outlier Status
In 2020 and again in 2024 reporting, NH was described as a regional outlier on climate and renewables policy. The 2025 reversal cements that position relative to its neighbors.
7) Fisheries, Environment, and the Gulf’s Warming Reality
Fisheries concerns are real—and addressable.
Floating arrays can be sited farther offshore; gear-compatible corridors and compensation frameworks are being debated across the North Atlantic. Maine’s process features intensive stakeholder work (and fierce disagreement). For NH, stepping back defers—but does not resolve—coexistence questions that will resurface if leasing returns.
Ecology & climate backdrop.
The Gulf of Maine is warming faster than most of the world’s oceans, disrupting species distributions and affecting fisheries economics—part of the argument some advocates use for decarbonizing electricity supply. Scientific outreach videos and academic sessions underscore the stakes for coastal New England.
8) Ratepayer Math: What the Pause Could Mean for Bills
Short-term: lower exposure to project cancellations and renegotiations.
Given recent contract terminations and price resets in the OSW sector, NH ratepayers avoid near-term surcharge risk from failed procurements. (Legislative debate in February emphasized affordability and “market-driven” choices.)
Medium-term: missed hedging.
OSW can hedge volatile fossil-fuel prices and diversify supply. By stepping back, NH leans more heavily on ISO-NE wholesale markets, imported power, and incremental onshore renewables. If regional OSW costs fall—and neighbors lock in long-term PPAs—NH may miss cheap-clean hedges in the 2030s. (Inference based on regional procurement dynamics summarized in public coverage and BOEM planning.)
9) Grid & Siting: Transmission Without Turbines?
Even without NH-sited turbines, the region may still need new transmission that crosses or interconnects in New Hampshire (to move Maine/Massachusetts clean power). NH’s diminished OSW role reduces its leverage over where lines land and how costs are allocated. If federal policy reinstates BOEM areas, Concord would be restarting from organizational zero—a time penalty in multi-year grid planning cycles.
10) Legal & Administrative Durability: How Hard Is This to Undo?
Because HB 682 repealed bodies and retitled offices, re-engagement requires new legislation or executive initiatives—and rebuilding staff, advisory groups, and MOUs with neighboring states. If federal policy reopens the Gulf, NH could stand up a lean task force quickly, but port development and workforce pipelines take years. The longer the pause, the wider the capability gap with Maine and Massachusetts.
11) Scenarios: What Might Happen Next?
Scenario A: Federal Policy Reopens the Gulf (2026–2028)
If OCS withdrawals are rescinded and BOEM restarts leasing, Maine and Massachusetts are prepared to move; NH would face the choice: re-enter with a small procurement plus workforce/port partnerships, or remain a pure importer of offshore wind electrons landing elsewhere.
Scenario B: OSW Costs Fall, Floating Matures
UMaine’s research array (and global projects) may drive cost reductions in floating platforms. NH’s 2025 retreat could look premature if regional LCOEs drop below mid-teens cents/kWh. Re-entry then becomes an economic decision rather than ideological.
Scenario C: Prolonged Federal Opposition
If federal withdrawals persist, NH’s policy is aligned with national headwinds. Focus shifts to onshore renewables, Canadian hydro imports, storage, demand-side management, and new gas infrastructure debates.
12) Policy Options If New Hampshire Wants to Keep Its Options Open
- No-Regrets Planning Keep a small cross-agency team to track BOEM and ISO-NE transmission initiatives; maintain data rooms, siting inventories, and draft MOUs with neighbors. (This can live within the Office of Energy Innovation without “offshore wind” branding.)
- Port-Light Strategy Rather than building a dedicated OSW port, structure contingent access agreements with Maine or Massachusetts facilities (Sears Island/New Bedford) if leasing resumes—plus barge-based assembly options for smaller components.
- Workforce “Evergreen” Skills Fund marine safety, heavy-lift, rope access, and HV electrical training that apply to multiple industries (ports, construction, transmission) and OSW if needed—so capacity is transferable. (This mirrors repealed OSW-specific training but broadens applicability.)
- Transmission Engagement Participate robustly in ISO-NE’s Public Policy Transmission processes even without OSW procurements, ensuring NH voices are heard on routing, cost allocation, and reliability benefits if neighbors bring power ashore.
- Fisheries Coexistence Playbook Study Maine/Massachusetts compensation and corridor models now; if leasing returns, New Hampshire can fast-track trust-building with local fleets.
13) The Politics: Identity, Independence, and the Granite State Brand
New Hampshire’s brand—frugal, independent, skeptical of mandates—makes the 2025 reversal politically legible: Concord opted out of a capital-intensive bet during a period of federal turbulence. Yet the decision also defines NH against its neighbors’ clean-industry ambitions. If the market turns, the state may face pressure from businesses and colleges to re-enter, potentially making offshore wind a recurring campaign issue through 2026 and beyond.

14) Frequently Asked Questions
Q: Does the 2025 state law block private developers from ever proposing offshore wind off NH?
A: It doesn’t ban private interest per se, but by removing state structures, it reduces coordination capacity, and with federal wind areas currently withdrawn, there is no active BOEM pathway to lease acreage in the Gulf of Maine anyway. Reinstating federal areas and re-creating state capacity would both be required.
Q: Could New Hampshire still get offshore wind power without hosting turbines?
A: Yes. NH utilities could contract for power that lands in Maine or Massachusetts, but the state would capture fewer local jobs and port benefits. Transmission cost allocation would depend on regional processes.
Q: What happens to the University of Maine research array if the Gulf’s commercial areas are paused?
A: The research lease is distinct and was advanced in 2024; it is designed to collect data and mature floating technology. Its findings could inform future commercial activity if/when federal policy allows.
15) Bottom Line
New Hampshire’s 2025 reversal is strategic retrenchment amid federal headwinds and industry volatility. In the near term, the state avoids tangible program costs and some exposure to project risk. The tradeoff is diminished influence over regional clean-power development, lost port/workforce optionality, and a slower starting position if the Gulf of Maine reopens. For a small coastal state with limited shoreline but central grid geography, staying engaged in planning—even without procurement—may be the best hedge.
