Massachusetts

Energy/Power is the dominant stressor: the public debate centers on whether data-center load growth will raise residential and small-business bills and force grid upgrades onto other customers (Sen. Markey). Water/Geology is secondary: Everett and Lowell opponents also raise cooling, environmental, and neighborhood impacts, but the strongest statewide political argument is electricity affordability rather than water supply (WBUR).

None identified. I found no 2026 Massachusetts federal, statewide, or municipal campaign where data centers are a central declared issue; the issue is showing up instead in local planning and zoning fights in Lowell and Everett, plus federal ratepayer letters from Sen. Ed Markey (D-MA).

Lowell enacted what appears to be the state’s first local data center moratorium in March 2026, a one-year pause on new data center development while zoning rules are reviewed (WBUR, Conservation Law Foundation). Everett is considering a restriction or possible ban in its Docklands Innovation District after the Planning Board endorsed an ordinance limiting data centers to a special permit and capping them at 20,000 square feet or 5 MW, but it has not enacted a citywide ban as of May 2026 (Boston.com, WBUR). At the state level, Massachusetts has not enacted a moratorium or ban; instead, it issued 400 CMR 9.00 in March 2026 to govern certification for the Qualified Data Center Sales Tax Exemption (Mass.gov 400 CMR 9.00).

Massachusetts’ main state-level policy signal is regulatory, not a direct cost-shift bill: 400 CMR 9.00 implements the Qualified Data Center Sales Tax Exemption certification process (Mass.gov 400 CMR 9.00). In the legislature, H.83 (2025-2026) would create a special legislative commission to study load growth due to AI and data centers, including electricity demand surges driven by data centers, and is referred to the Joint Committee on Advanced Information Technology, the Internet and Cybersecurity (Massachusetts Legislature H.83). On the cost-allocation side, Sen. Ed Markey and New England colleagues urged state energy regulators and NARUC to protect residential and small business ratepayers from data-center-driven rate hikes and to reject filings that force households to subsidize data centers (Sen. Markey).

None identified.

1) Markley Group data center, Lowell — existing/expanding 352,000-square-foot facility in the Sacred Heart and Back Central neighborhoods; status: heavily contested and now subject to resident litigation and the city moratorium (Yale Law School, CLF). 2) Everett Docklands Innovation District / former ExxonMobil site, Everett — proposed use could include a data center; status: contested, with Planning Board restrictions moving through local process (Boston.com, WBUR). 3) General Lowell new-build market — not a single named project, but the citywide moratorium has effectively paused new projects while zoning is rewritten (WBUR).

None identified at the state political-surface layer as of May 2026. Talent and workforce dynamics in Massachusetts surface primarily at the sub-state and labor-market level — county and municipal proceedings on named projects, regional building trades council positions, and utility commission workforce testimony — which are out of scope for the tracker's state-political-surface read.

Emerging cluster. Massachusetts is not yet a major national hub, but it has a meaningful and growing set of facilities in Greater Boston/Merrimack Valley; WBUR noted in April 2026 that there still are not many large data centers in the state (WBUR).

“The pause appears to be the first of its kind in Massachusetts,” WBUR reported of Lowell’s one-year moratorium on data center development (WBUR).
