Massachusetts' plan to cut Mass Save funding looks like electric bill savings. It isn't.

Massachusetts homeowners have gotten real results from Mass Save. Since 2008, the state's flagship energy efficiency program has helped hundreds of thousands of households weatherize their homes, switch to heat pumps, and cut their energy use—often at little or no cost. Between 2012 and 2023, the program delivered more than $34 billion in total benefits to Massachusetts residents, according to the Acadia Center.

So it's worth paying close attention to what the Massachusetts House just voted to do to it.

At the end of February 2026, the House passed a sweeping energy affordability bill, which is now headed to the Senate. The legislation contains a lot that clean energy advocates support, like provisions for solar on affordable housing, expanded municipal solar options, and streamlined permitting, which would reduce the state’s reliance on expensive fossil fuels over time.

But it also includes a $1 billion cut to Mass Save's current budget. That's the part experts say could end up costing homeowners more in the long run, not less.

“The climate omnibus bill contains critical solar policy provisions that will help make our grid more reliable and more affordable," Elena Weissmann, Northeast Regional Director of Vote Solar, said in a statement. "At the same time, the proposed funding cuts to the Commonwealth's nation-leading energy efficiency program would meaningfully harm our state's efforts to address the energy affordability crisis."

Here's what you need to know before the Senate takes its turn.

Mass Save is a collaboration among the state's gas and electric utilities to empower residents, businesses, and communities to make energy efficiency upgrades, funded through a small charge on utility bills.

The program's current 2025-2027 plan aims to weatherize more than 184,000 homes and support heat pump installations in roughly 119,000 households, according to Mass Save's own projections. It also has a particular focus on reaching the households that need it most—with a historic commitment to low- and moderate-income residents.

House Bill 5151 would cut $1 billion from Mass Save's current $4.5 billion three-year budget cycle, targeting its administrative, marketing, and advertising spending. The bill also orders an inspector general review of the program. 

In theory, the goal of the Mass Save cut is to save ratepayers money. Before the vote, House budget chief Aaron Michlewitz framed it to reporters as “allowing some money to go back directly into the pockets of our constituents.” Energy committee chair Mark Cusack, who introduced the bill, “described the reductions as ‘a one-year pause’" targeting administrative and marketing budgets that he called "bloated," adding that the cuts were "not at the programmatic level," according to WBUR. 

But independent analysts and energy efficiency advocates say the scale of the cuts makes that framing hard to square with reality. The timing makes the impact more severe, and too large to absorb through marketing and overhead alone. Because the three-year plan is already underway, much of the budget will be committed before any legislative change takes effect. That means the remaining programs would likely absorb most of the $1 billion reduction, according to Canary Media. 

For example, when the state's Department of Public Utilities cut $500 million from Mass Save's budget in early 2025, utilities subsequently proposed their largest reductions to heat pump incentives and weatherization services. A cut twice that size would go considerably deeper—and would hit hardest the low-income residents the current Mass Save plan was specifically designed to benefit.

"This cut would utterly devastate and probably break the program," Kyle Murray, Massachusetts program director at the Acadia Center, told CommonWealth Beacon. "The effect that this would have is [to] basically grind the program to a halt."

The case against cutting Mass Save comes down to how the program actually works. By helping homes and businesses use less energy in the first place, Mass Save reduces overall demand on the grid. Less demand means less need for new power plants, transmission lines, and other infrastructure—all of which ratepayers fund through their utility bills. Pull back the program, and those avoided costs start coming back.

According to the Green Energy Consumers Alliance, for every dollar spent on Mass Save, residents get back approximately $2.72 in benefits—including lower energy bills, reduced pollution-related costs, and avoided health care expenses related to improved air quality.

The long-term math tells the story clearly. Between 2016 and 2024, Massachusetts ratepayers would have paid roughly $16 billion more in electric and gas supply and infrastructure costs if Mass Save hadn't existed, Murray told the New Bedford Light. During that same period, the state spent $8 billion on Mass Save—resulting in a net benefit of $8 billion that shows up on every ratepayer's bill, whether they ever used a program incentive directly, or not.

"Energy affordability and clean energy are not at odds," Murray told WBUR. He warned that while the bill contains many bright spots, the cuts to energy efficiency need to be rectified. "Failing to do so will make this package a net-loser for families, who will be left paying dearly for more expensive conventional fuel and infrastructure," he said.

Massachusetts homeowners are right to be frustrated with their energy bills—they rank among the highest in the country. But the Mass Save line item isn't what's driving that. The state gets more than half its power from natural gas, and in January 2026, wholesale natural gas prices jumped 43% compared to a year earlier, according to ISO New England. 

Fossil fuel prices tied to global markets—not energy efficiency programs—are the main reason bills are so high. Meanwhile, Eversource reported $1.69 billion in earnings in 2025, nearly doubling its profits from the prior year, even as its customers struggled to pay bills. 

The House bill also does not address the Gas System Enhancement Program (GSEP), a ratepayer-funded pipeline replacement program that has grown from $291 million in annual spending in 2015 to a proposed $880 million in 2025—an average increase of 12% per year, according to the Massachusetts Attorney General's Office. And GSEP spending ultimately exceeded that proposal, reaching $901 million in 2025. GSEP currently accounts for about 8 to 11% of gas ratepayers' monthly bills. 

The Department of Public Utilities moved in April 2025 to rein in that spending following advocacy from Attorney General Campbell, but the program's legacy costs continue to weigh on bills.

There is a legitimate equity concern at the center of this debate—but it points toward fixing Mass Save, not cutting it.

A 2025 report from the State Auditor's Office found real gaps in how Mass Save benefits are distributed. Residents of Environmental Justice communities and Gateway Cities were paying more into the program per capita than they were getting back. In communities with over 90% Environmental Justice populations, residents contributed on average 151% more per capita than municipalities without such populations. Poorer communities paid roughly 24% more per capita than the state average while receiving fewer benefits.

That's a problem definitely worth solving. But cutting $1 billion from the program's budget doesn't solve it—it just removes the resources needed to fix it. The current 2025-2027 plan was specifically built to close those gaps, with a $1.9 billion equity commitment—the largest in the program's history—including $1.3 billion for low- and moderate-income households and over $615 million for renters. 

According to 350 Mass, that investment is already working: In 2025, for the first time ever, low- and moderate-income households received more than half of all Mass Save incentives—up from under 30% in 2022. A $1 billion cut would reverse that trajectory and lengthen what are already long waiting lists for services.

There's also a practical problem with the "affordability" framing as it applies to lower-income households specifically. Many of these households are already on discounted utility rates, which means a small reduction in this bill charge doesn't meaningfully lower what they pay. What actually lowers their energy costs—which can consume anywhere from 6% to 15% of household income—is weatherization, insulation, and efficient heating systems like heat pumps. Those are precisely the Mass Save services that a $1 billion cut would put out of reach, according to 350 Mass.

For the low-income residents that have spent years fighting for a fair share of these programs, the timing couldn't be worse—especially as federal clean energy incentives continue to be rolled back at the national level.

The bill now moves to the Massachusetts Senate, where the outlook looks different. Senate President Karen Spilka has said she “will not back off for our climate,” according to WBUR. And Senate energy committee co-chair Michael Barrett has been a consistent voice for balancing affordability with clean energy progress. 

"At the end of the day, the Legislature's aim should be to produce the best balance, which means giving people real financial relief while pushing back hard against climate change," Barrett told CommonWealth Beacon. "In Massachusetts, people want both."

There is still a real opportunity for the Senate to put forward a version of this bill that takes on the actual drivers of high energy costs—fossil fuel price swings, utility profits, GSEP pipeline spending—without pulling the rug out from one of the most cost-effective tools the state has for keeping bills down long term.

If you're a Massachusetts resident, now is the time to make your voice heard. Find your state senator using the Massachusetts Legislature's legislator finder and reach out directly—and share what’s happening with your friends and family. Whether you've used Mass Save programs to lower your own bills, or you simply want your senator to know that short-term fixes shouldn't come at a long-term cost, your message matters.

The charge on your bill for Mass Save is small. The cost of ending the program that prevents much bigger charges down the line could be a lot larger.
