New Hampshire ratepayers have been told for years that the Granite State is at the mercy of forces it cannot control. Cold winters. Constrained pipelines. Liquified natural gas tankers whose prices swing with global crises in places most Granite Staters could not find on a map. A new commentary published this week in New Hampshire Bulletin argues that the region now has a serious tool for breaking that dependence. Two large offshore wind projects, Vineyard Wind off Massachusetts and Revolution Wind off Rhode Island, are operating, delivering electricity to the grid, and reshaping the math on what New England energy bills could look like in future winters.

The Bulletin commentary lays out a case familiar to anyone who has paid a Granite State electric bill in February. New England’s energy costs sit as much as 39 percent above the national average, driven principally by overreliance on liquified natural gas. LNG prices are at the mercy of global commodities markets, geopolitical disruptions, and the cost of building and maintaining the infrastructure needed to deliver the fuel to homes and businesses. That dependency has produced a region-wide pattern in which one cold snap can send wholesale electricity prices through the roof, with ratepayers footing the bill weeks later through pass-throughs and adjustment riders.

Vineyard Wind and Revolution Wind, By the Numbers

The two operating offshore wind projects together represent a meaningful share of the renewable capacity now feeding the New England grid. Vineyard Wind in Massachusetts waters and Revolution Wind off Rhode Island have a combined capacity of roughly 1,500 megawatts of clean electricity. That is enough to power hundreds of thousands of homes in the region and to displace a non-trivial share of the LNG that would otherwise be burned during peak demand periods.

Revolution Wind came fully online earlier this year after surviving a series of legal challenges and political obstacles, including direct hostility from the Trump administration, according to NHPR. Connecticut officials celebrated the project’s full operation in March, framing it as the first major offshore wind facility delivering electrons to the New England grid at full scale. Vineyard Wind reached commercial operation earlier and has been ramping up its output through 2025 and into 2026.

The numbers from independent studies on these projects are striking. A study covered by NHPR earlier this year found that if Vineyard Wind and Revolution Wind had been operating at full capacity during the winter of 2024-2025, the region would have experienced only 24 days of energy shortfall risk, compared to 53 days without them. That is more than a halving of the period during which New England’s grid operator would need to invoke emergency measures or pay premium prices for last-minute generation. The same analysis suggested offshore wind, with its near-zero marginal operating cost, would have pushed wholesale prices down to a stabilized band of roughly $80 to $90 per megawatt-hour during high-stress winter periods, well below the spikes seen during recent cold snaps.

What This Means for New Hampshire Households

New Hampshire has no offshore wind projects of its own. The Granite State coastline is short, the federal lease blocks adjacent to New Hampshire are limited, and political resistance to coastal development has historically been intense. But because the New England grid is operated as a single region by ISO New England, electrons generated in Massachusetts and Rhode Island waters flow into New Hampshire homes through the same transmission system that delivers power generated elsewhere. When wholesale prices drop because more low-cost wind is feeding the grid, New Hampshire ratepayers benefit too.

The mechanism by which those savings reach households is not always obvious. New Hampshire residential customers see the effects on their bills through default-service rates set by utility commissions and through the rates charged by competitive suppliers. Both reflect, with a lag, what generators are charging in the wholesale market. When wind is bidding into the market at near-zero marginal cost, the next-most-expensive generators that would otherwise set the clearing price drop out, and the entire market clears at a lower number.

That said, the savings are not guaranteed and not evenly distributed. Generation cost is only one component of a residential bill. Distribution, transmission, and a long list of state and federal riders make up the rest. Pipeline constraints into New England remain a structural problem, particularly during severe cold snaps when natural gas demand from heating customers competes with demand from electricity generators. Offshore wind helps with this competition by displacing the marginal LNG generator, but it does not eliminate the underlying physical constraint.

The Politics of Offshore Wind in 2026

The political environment for offshore wind has grown more hostile at the federal level. The Trump administration has openly opposed offshore wind development on the East Coast, halted new federal lease auctions, and attempted to slow permitting on projects already in the pipeline. Revolution Wind itself faced multiple legal challenges that delayed its full operation by months. Despite that resistance, the projects under construction or fully permitted before the administration’s reversal have continued to advance.

For New Hampshire policymakers, the question is whether to lean into the regional benefits of offshore wind or to bet on an alternative strategy. Gov. Kelly Ayotte has emphasized an all-of-the-above approach to energy that includes renewables, but the state has not committed to specific offshore wind procurement. Massachusetts, Rhode Island, and Connecticut have each invested billions in long-term offshore wind contracts. New Hampshire’s neighbors are essentially subsidizing a clean-energy infrastructure that benefits the Granite State at the wholesale market level. Whether to participate more directly in those procurements, or whether to free-ride on neighboring states’ commitments, is a live policy question.

The Granite State’s biggest near-term energy challenges remain on the demand side. The growth of data centers, the electrification of heating, and the gradual expansion of electric vehicle charging are all driving up baseline electricity demand. Offshore wind alone will not solve those problems. But it is one of the few sources of new generation that can come online at scale within a five-year planning horizon and that does not require new pipeline infrastructure crossing northern New England.

What to Watch Next

Several projects in the development pipeline could meaningfully expand the region’s offshore wind capacity over the next several years if they survive permitting and financing challenges. Massachusetts, Rhode Island, Connecticut, and Maine have all signed power purchase agreements with developers for additional capacity. Whether those contracts translate into operating turbines depends on a combination of federal regulatory posture, supply chain conditions for turbine components, and the willingness of state utility commissions to allow the cost recovery that developers need to finance new construction.

For New Hampshire residents trying to figure out what their winter heating bills will look like in 2027 and 2028, the answer increasingly depends on what happens 30 to 50 miles offshore in waters Massachusetts and Rhode Island regulate. As the New Hampshire Review has covered in coverage of the EPA’s PFAS rollback, transmission line lawsuits, and the Granite State’s broader energy debate, the structural cost of electricity is one of the most consequential issues facing households and small businesses in the state. Offshore wind is not a silver bullet. But it is among the few near-term options that could put real downward pressure on the wholesale prices that drive what Granite Staters pay every month.

Does New Hampshire have any offshore wind projects of its own?

No. New Hampshire has not procured any offshore wind capacity. The state's short coastline and limited federal lease areas nearby make in-state development difficult, but because the New England grid is operated regionally by ISO New England, electrons generated by projects in Massachusetts and Rhode Island waters flow into New Hampshire through shared transmission infrastructure.

How much electricity do Vineyard Wind and Revolution Wind produce?

The two operating projects have a combined capacity of approximately 1,500 megawatts. Vineyard Wind, in Massachusetts waters, was the first to reach commercial operation. Revolution Wind, off the coast of Rhode Island, came fully online in March 2026 after surviving legal and political challenges.

Why are New England's electricity prices 39% above the national average?

The region's heavy dependence on liquified natural gas for both heating and electricity generation drives volatile wholesale prices, particularly during winter cold snaps when supply tightens. LNG prices are tied to global commodity markets and geopolitical events, and the infrastructure needed to deliver the fuel adds further cost to ratepayer bills.

Would offshore wind have prevented a winter energy crisis?

According to a study covered by NHPR, if Vineyard Wind and Revolution Wind had been at full operation during the winter of 2024-2025, the region would have faced just 24 days of energy shortfall risk versus 53 days without them. Offshore wind's near-zero marginal operating cost can also push down wholesale prices during peak demand periods.

What is the federal government's position on offshore wind?

The Trump administration has opposed offshore wind development, halted new federal lease auctions, and slowed permitting on some projects. However, projects already permitted and under construction, including Vineyard Wind and Revolution Wind, have moved forward, and state-level procurement programs in Massachusetts, Rhode Island, Connecticut, and Maine continue to drive new development.
