Net Metering Hangs in the Balance as NH Lawmakers Leave Solar's Future Unsettled

New Hampshire spent another full legislative session arguing about how to value the electricity that homes, towns, and businesses pour back onto the grid, and it is ending that session almost exactly where it started: without a clear answer. The yearslong fight over net metering, the framework that pays the owner of a solar array or other small generator for the surplus power they send back to the utility, wore on through committee rooms and floor votes this spring. Yet as lawmakers prepare to close out the session, the long-term shape of the program is still unsettled, and energy experts warn that the lingering uncertainty could cost the state real investment in cleaner, more diversified power. As the New Hampshire Bulletin reported, a handful of bills tried to clarify where New Hampshire stands, but none delivered the broad certainty developers say they need.

What net metering actually does

Net metering is easy to describe and surprisingly hard to legislate. When a solar panel on a school roof or a town hall generates more electricity than the building is using at that moment, the extra power flows back onto the grid, and the customer earns a credit for it. The disagreement is over how much that credit should be worth, how long the arrangement should last, and who should be allowed to participate. States, and even programs within states, land all over the map on those questions, setting different compensation rates, different sunset dates, and different eligibility rules.

New Hampshire has its own wrinkle called group net metering, which lets several entities share the output of a single array. For larger installations, those rated between 1 and 5 megawatts, participation is effectively limited to municipal players. Sam Evans-Brown, executive director of Clean Energy New Hampshire, described that universe as “towns, wastewater treatment plants, town halls, and schools.” Those are exactly the kinds of public hosts that can spread the benefit of a single solar field across a community, which is part of why the policy debate carries weight well beyond the energy sector.

Senate Bill 538: a narrow fix, not a grand bargain

The one measure that emerged from the committee of conference process with bipartisan support was Senate Bill 538, sponsored by Dover Democratic Sen. David Watters. The bill takes aim at a specific cliff: under current law, net metering for municipal group projects is set to expire in 2040. That may sound far off, but for a developer trying to finance a project that will operate for decades, a 2040 cutoff is uncomfortably close. Evans-Brown said that term is simply too short to assure many developers, and the banks behind them, that a project will pencil out financially. SB 538 would extend the participation term and, in doing so, hand a measure of confidence to projects that are planned but still waiting for clearance.

There is a significant catch. The bill applies only to projects already sitting in the interconnection queue, meaning they have formally applied to their local utility to plug into the grid by the time the law takes effect. Anything proposed after that point gets no relief. “Senate Bill 538, really, is just about trying to preserve that diminished pipeline of solar projects that we are hoping could get done,” Evans-Brown said. In other words, the bill protects a shrinking batch of in-flight projects without resolving the bigger question of whether new group net metering projects will have a viable path at all.

Why financing hinges on certainty

The financing problem sits at the center of this whole debate. Developers and their lenders need predictability to commit capital, and a floating or uncertain compensation rate makes that nearly impossible. One developer quoted in the reporting put it bluntly: “We do need that for financing. There’s no way we can finance a project that’s got a floating rate unless we establish some form of a floor.” That single sentence captures why the Legislature’s indecision matters in dollars and not just in principle. A rate floor, a firm term, and clear eligibility rules are not bureaucratic niceties. They are the difference between a project that gets built and one that stays on paper.

For the public hosts, the calculus is similar but tinged with caution. “There’s definitely some risk on our end. This is the kind of project we want to support, though,” one participant said, reflecting the willingness of towns and institutions to lean into clean energy when the rules give them enough footing to stand on. The risk is real because these are public dollars and public assets, and a poorly structured deal can leave taxpayers exposed.

What it means for Granite Staters

The stakes reach ordinary ratepayers in a few ways. Group net metering projects can lower energy costs for participating towns and schools, which ultimately shows up in local budgets and property taxes. They also add locally generated, diversified supply to a regional grid that has struggled with price volatility and transmission constraints. When the state cannot say with confidence what its net metering policy will be in five or ten years, developers look elsewhere, and New Hampshire loses out on the investment, the construction jobs, and the long-term supply those projects would bring.

This session’s outcome fits a pattern Granite State energy watchers have grown used to: incremental, defensive fixes rather than a durable framework. SB 538 preserves a pipeline rather than expanding one. That is not nothing, but it is far from the clarity that clean energy advocates, municipal officials, and developers have been asking for. The broader uncertainty around future projects, which are not currently eligible for net metering on favorable terms past the existing cutoffs, remains the unfinished business lawmakers will likely revisit next year.

For now, the message to anyone watching New Hampshire’s solar economy is to keep expectations measured. A few municipal projects already in the queue may breathe easier. Everyone else is still waiting for the state to decide what it actually wants its clean energy future to look like.

What is net metering in New Hampshire?

Net metering is a billing framework that compensates the owner of a small power generator, such as a solar array, for surplus electricity they send back onto the grid. New Hampshire also offers group net metering, which lets multiple entities share the output of a single array.

What does Senate Bill 538 do?

SB 538, sponsored by Sen. David Watters of Dover, would extend the term that municipal group net metering projects can participate in the program beyond the current 2040 expiration. It applies only to projects already in the interconnection queue when the law takes effect.

Why does net metering certainty matter for developers?

Developers and their lenders need predictable compensation rates and terms to finance projects. A floating rate or a short program window makes it difficult or impossible to secure financing, which can stop otherwise viable solar projects from being built.

Who can participate in group net metering for larger arrays?

For arrays rated between 1 and 5 megawatts, participation is generally limited to municipal entities such as towns, wastewater treatment plants, town halls, and schools.
