Nearly a year after Massachusetts regulators laid out a vision for the state’s evolution from natural gas distribution to clean energy use, lawmakers are coalescing around legislation that would start converting principles into policy.
The wide-ranging climate bill includes several provisions that would allow utilities to explore alternatives to gas and empower regulators to place more limits on the expansion and continuation of natural gas infrastructure, changes that supporters say are critical to a successful transition away from fossil fuels.
“This bill is a major first step in empowering [regulators] to do something rather than just rubber stamping the utilities’ plans,” said Lisa Cunningham, co-founder of ZeroCarbonMA.
Natural gas is currently the primary heating source for half the homes in Massachusetts, a number that needs to drop if the state is going to meet its ambitious climate goal of net-zero emissions by 2050, advocates and state leaders say. In 2020, the state department of public utilities opened an investigation into the role natural gas utilities would play in the transition to cleaner energy. In December 2023, the department issued a lengthy order concluding that the state must move “beyond gas” and outlining a broad framework for making the shift.
Lawmakers attempted to start turning these general ideas into binding law earlier this year, but the legislative session closed at the end of July before the Senate and House reconciled the differences between their versions of a climate bill. Legislators returned to work this fall and hammered out an agreement, and the Senate passed the resulting bill last week. The House speaker has said the body will vote when it returns to formal session later this year. The bill is generally expected to pass and be signed into law.
“A lot of people were skeptical we’d get a bill at all, but I’m happy with where this bill ended up,” said Kyle Murray, Massachusetts program director for climate nonprofit Acadia Center. “It shows a step toward that needed urgency.”
At the heart of the bill’s energy transition provisions is a change to the definition of a natural gas utility that allows the companies to also provide geothermal power. Networked geothermal — systems that draw heat from the earth and deliver it to a group of buildings — is widely seen as a promising alternative to natural gas, and both National Grid and Eversource have pilot projects in the works. However, current law prevents the utilities from pursuing such projects without specific authorization from regulators. The climate bill would remove this barrier, making it easier for gas companies to explore new approaches to business.
“The gas utilities deeply need a new business model that can help them step into the future,” said Audrey Schulman, founder of climate solutions incubator HEETlabs. “That allows them to potentially evolve.”
This definition change supports other provisions aimed at slowing the expansion of natural gas use in the state. The bill would end the requirement that natural gas utilities provide service to any customer in their service area who requests it, with few exceptions. Under the new law, utilities could decline these requests when other alternatives are available.
The bill would also allow regulators to consider the impact of emissions when deciding whether to approve requests to expand natural gas service into new communities. In 2023, the state approved a request to bring gas service to the central Massachusetts town of Douglas. Regulators at the time noted that the decision works against the state’s goal of phasing out natural gas, but said the law gave them no choice but to approve the plan. Provisions in the climate bill would untie regulators’ hands in such cases in the future.
“The [Department of Public Utilities] can consider the public interest, including climate, it doesn’t have to say yes to more gas service,” said Amy Boyd Rabin, vice president of policy at the Environmental League of Massachusetts. And the inclusion of geothermal in gas utilities’ definition means “now there’s also something else to offer the customers.”
Another major element of the bill would reform the state’s Gas System Enhancement Plans program, which encourages utilities to repair or replace pipes in the state’s aging and leak-prone natural gas distribution system. Clean energy advocates have often argued that these plans are problematic, investing billions of ratepayer dollars into shoring up a system that is increasingly obsolete. The climate bill would allow utilities to choose to retire segments of pipe rather than fixing them.
“For the first time ever they are able to look at a pipe and say, ‘You know what, this is not worth the cost,’” Murray said. “We don’t want ratepayers shouldering the burden for a lot of stuff that’s not going to be useful in five to 10 years.”
Environmental advocates praised the bill’s gas provisions, and are already focusing on what more there is to be done. Several would have liked to see a more aggressive phasing out of Gas System Enhancement Plans, with a specific end date. Others champion an expansion of a pilot program that allows cities and towns to ban fossil fuel use in new construction and major renovations.
“There is no reason why communities that want to enact this via home rule petition should be restricted from enacting the will of their constituents,” Cunningham said.
In the meantime, advocates are ready to see the climate bill turning into reality.
“There’s a lot of good stuff in there that will do a lot of good for the commonwealth,” Boyd Rabin says.
