Wilmington officials are moving to slam the door on massive AI data centers before one ever gets built in town, drafting a zoning bylaw that would cap facilities at just 2 megawatts of power and require special permits for anything under that threshold. The Planning Board has scheduled a public hearing for September 29 at 7 p.m. to weigh the proposal, which would make Wilmington the latest Massachusetts community to wall itself off from the artificial intelligence infrastructure boom sweeping the region.
Wilmington Planning and Development Director Valerie Gingrich says data centers have existed for quite some time, but the scale of what companies want to build now is a different animal entirely. As reported by the Boston Herald, Gingrich said artificial intelligence has driven a surge in demand for large hyperscale data centers, which consume far more power and resources than the traditional facilities the town is used to. Wilmington currently has no data center land-use category on its books at all, and Gingrich has said the town's existing blanket prohibition on unlisted uses could be vulnerable to a legal challenge under its current wording.
How the 2-Megawatt Line Would Work
Under the draft bylaw, small data center facilities drawing less than 2 megawatts could still operate, but only within the town's highway industrial and general industrial district zones, and only after clearing a special permit process. That review would examine noise generation, water use and power draw before any permit is issued. Permits would be valid for five years and would require renewal, along with ongoing reporting from operators, per the Herald's account of the proposal. Anything pulling more than 2 megawatts would be prohibited outright, while businesses that already run smaller, accessory data centers as part of other operations could keep using them.
To put that 2-megawatt ceiling in perspective, ISO New England figures show that a single megawatt of capacity typically serves roughly 750 to 1,000 average New England homes, according to WROR. That means Wilmington's cap would limit local facilities to something like the power draw of 1,500 to 2,000 households — a fraction of what a hyperscale campus can demand.
Wilmington Borrows Mansfield's Playbook
Select Board member Jacob Gearwar, who helped draft the language, said the Wilmington proposal closely mirrors a bylaw already approved by Mansfield and the Massachusetts Attorney General's Office, according to the Herald. That approval matters: the Attorney General's Municipal Law Unit signed off on Mansfield's framework on September 1. The tiered system limits Tier I facilities to 2 megawatts or less, and the bylaw is believed to be the state's first such measure, per the Attorney General's Municipal Law Unit as reported by Harrington Heep. Gearwar told the Herald he supports Wilmington's version as written, saying the bylaw makes sense and should clear the Attorney General's office easily.
Hoodline previously reported on Mansfield's move to cap power-hungry hubs back in May, when the town first adopted the same 2-megawatt threshold Wilmington is now borrowing. Wilmington began discussing its own version of the bylaw that same month, according to the Herald, putting the town roughly four months into a process that has picked up steam as state policy has shifted around it.
State Policy Is Moving in the Same Direction
That shift has been dramatic. The Healey administration paused applications for the state's qualified data center sales and use tax exemption on June 25, releasing a policy framework requiring developers to cover the full cost of their own energy infrastructure and clean power, according to the Massachusetts Municipal Association. The Herald similarly reported that the Healey administration required data-center operators to shoulder the full cost of their own energy supply, and that any power feeding a data center must come from clean energy resources.
Governor Maura Healey went further on September 8, signing Executive Order 658, which requires data center projects with peak electricity demand above 25 megawatts to secure local community approval and sign a Community Benefits Agreement before receiving state permits. The order also created a Ratepayer Protection Fund, requiring payments from large data centers when they cannot generate or procure sufficient incremental clean electricity, as detailed by The New Bedford Light. Grid operators and consumer advocates have raised concerns that sudden spikes in large-load electric demand could otherwise shift infrastructure upgrade costs onto residential ratepayers.
A Regional Backlash Takes Shape
Wilmington isn't acting in isolation. The Lowell City Council unanimously enacted a 360-day moratorium on new data center construction and expansions in March, one of the first such freezes in the state, sparked by residents' complaints over the 352,000-square-foot Markley Group facility, according to Yale Law School. In August, a Massachusetts Superior Court judge issued a preliminary injunction blocking Markley from installing four additional backup diesel generators at that Lowell site while a lawsuit over air and noise pollution proceeds, as Hoodline reported in its coverage of the diesel generator ruling. The Herald included a photo of the Markley Lowell facility as seen from Otis Street, credited to photographer Amanda Sabga.
The pushback extends to local policy debates, too. Not every community is choosing an outright ban; some proposals would regulate data centers through special permits rather than prohibit them entirely.
What's Still Unresolved
New England has operating data centers, including in Massachusetts, while high electricity prices and expanding local zoning bans have become part of debates over new hyperscale proposals. Whether developers will challenge 2-megawatt municipal caps like Wilmington's in court, and how utilities adjust grid planning around a growing patchwork of local bans, remain open questions as towns across the state weigh the same tradeoff between blocking heavy resource users and forfeiting potential tax revenue.
