As of July 1, 2026, Massachusetts' new consolidated siting and permitting framework is live. If you're developing a large battery storage facility or clean energy project in the Commonwealth, community engagement is no longer a nice-to-have you get to after the engineering is done. It's a pre-filing requirement. You have to do it before the Energy Facilities Siting Board will even take your application.
The law firms have written plenty about what the regulations say. I want to talk about what they mean in practice, because I've spent 25 years in the rooms where projects actually live or die. The planning board meeting. The town meeting floor. The senior center info session where the fire chief gets asked the same question forty times.
Here's the truth the regulations are built on: projects don't die in the permitting office. They die in the community. They die when residents learn about a project from a headline instead of from the developer. They die when the first public meeting turns hostile because nobody did the work before the site plan showed up.
Under the 2024 Climate Act's implementing regulations, large clean energy facilities — including battery storage projects of 100 megawatt hours or more — must complete detailed pre-filing consultation and community engagement before filing with the EFSB. The rule is 980 CMR 16.00, Pre-filing Consultation and Engagement Requirements. Municipalities must stand up consolidated local permitting for smaller projects by October 1, 2026, under 225 CMR 29.00.
The state's own summary of what large projects owe the host community, from the March 5, 2026 announcement: two public meetings, translated materials, summaries of the comments received, and discussion of a community benefits agreement. In exchange, the EFSB issues a single consolidated permit covering state and local approvals, on a clock of roughly one year.
Translation: the state has formalized what smart developers already knew. You engage early, honestly, and in plain language, or you spend the next three years fighting about it.
Checking the regulatory box is the floor, not the goal. The goal is walking into your EFSB filing with a community that doesn't feel blindsided. In my experience, that takes five things:
1. Know the room before you enter it. Stakeholder mapping isn't a spreadsheet exercise. It's knowing which councilor ran on opposing the last project, which neighborhood group has the Facebook page, and what the fire chief needs to say yes.
2. Plain language beats technical accuracy delivered badly. Thermal runaway data doesn't calm a room. A firefighter explaining the response plan in his own words does.
3. Show up before you have to. The first time residents meet your team should not be the public hearing. By then, positions are hardened and you're negotiating against a headline.
4. Local media is part of the process, not a threat to it. The story is going to get written. The only question is whether you helped shape it or reacted to it.
5. Respect is the strategy. Communities can tell the difference between engagement and box-checking. So can the AGO, the EFSB, and the reporters covering your hearing.
Massachusetts communities are pushing back on development harder than they have in a generation. Data centers are getting banned outright. BESS moratoriums keep getting proposed even as the AGO keeps rejecting them. The state's answer was to protect projects legally while requiring developers to earn trust locally. Both halves matter.
The projects that get built over the next five years won't be the ones with the best lawyers. They'll be the ones the community doesn't feel blindsided by.
This piece is the practitioner's layer on top of the official record. Read the record too:
Don Martelli has led community relations and public affairs work behind more than 165 million square feet of permitted development in Massachusetts, including Suffolk Downs, MarketStreet Lynnfield, and active battery storage engagements. He is the founder of PR Bunker and president of the Revere Chamber of Commerce. If you're facing a siting fight or want to avoid one, reach him at don@prbunker.com or schedule a call.
The EFSB switched to the new process on July 1, 2026. The pre-filing rule, 980 CMR 16.00, took effect February 27, 2026. Under the 2024 Climate Act’s implementing regulations, large clean energy facilities, including battery storage projects of 100 megawatt hours or more, must complete pre-filing community engagement before the Energy Facilities Siting Board will accept their application. Municipalities must stand up consolidated local permitting for smaller projects by October 1, 2026.
Documented, pre-filing consultation with the host community: identifying stakeholders, holding accessible public sessions (two for large projects), providing plain-language and translated project information, publishing summaries of the comments received, discussing a community benefits agreement, and showing the EFSB that resident input was gathered and considered before the application was filed. Checking the box is the floor. Walking in with a community that doesn’t feel blindsided is the goal.
The regulations don’t require one, but the work does. Stakeholder mapping, plain-language materials, hostile-room facilitation, and local media strategy are specialized skills, and most development teams don’t carry them in-house. That gap is exactly what a community relations practice exists to fill.
