Why Massachusetts paused data center tax breaks over energy, water, noise, and local costs

Massachusetts pauses data center incentives

Massachusetts paused new tax incentives for data centers after Governor Maura Healey raised concerns about energy bills, water systems, noise, and local costs for host communities across the state.

The move affects a sales and use tax exemption created in 2024, before any developer received certification or filed a completed application under the Massachusetts program rules for review.

What the exemption offered

The Qualified Data Center Sales and Use Tax Exemption gives approved facilities a 20-year break on eligible construction, equipment, software, and electricity purchases for certified projects inside Massachusetts.

Applicants must meet state standards, including a requirement to create or maintain at least 100 Massachusetts jobs within five years after certification for each approved facility to qualify.

Energy costs shaped the decision

Governor Healey linked the pause to utility costs, warning that large computing projects must not raise gas or electric bills for households and businesses near host areas during development.

Her June 25, 2026, framework tells developers to bring their own clean energy and meet 100% of demand without shifting power costs onto other ratepayers under incentive review.

Grid upgrades face closer review

State guidance places power infrastructure under closer review, including lines, substations, and upgrades needed to serve large computing loads without adding costs for existing ratepayers during project evaluation.

Developers seeking public incentives would need to pay for added electric infrastructure, rather than shift those costs to households and businesses through future utility bills under the framework.

Water supplies entered the debate

State guidance says host communities should not experience water scarcity, wastewater strain, or increased system costs due to data center operations during regular use or drought periods in Massachusetts.

Projects would need suitable water supplies, infrastructure capacity, efficient cooling systems, and reuse strategies, where feasible, before state or local approvals move through the framework review for each proposal.

Noise and air impacts drew attention

Healey’s framework directs developers to reduce noise, air emissions, and other local effects from cooling equipment, backup power systems, and constant operations near homes and businesses where possible.

Those expectations connect tax policy with neighborhood conditions, including equipment hums, generator testing, and resident complaints around large facilities near homes, streets, and local businesses in affected communities.

Fun fact: U.S. data centers use 10 to 50 times more energy per square foot than typical office buildings do in operation.

Local governments keep a role

The administration expects cities and towns to join early talks before developers receive public support or advance through local review for large computing sites in affected Massachusetts communities.

State guidance points to community benefits plans, direct resident outreach, and local agreements covering jobs, infrastructure, and neighborhood conditions before officials formally consider incentives, permits, and project approvals.

Little-known fact: Data centers’ share of annual U.S. electricity use more than doubled, rising from 1.9% in 2018 to 4.4% in 2023.

Jobs remain part of the review

The tax break began as an economic development tool, with job rules tied to certification and eligible spending connected directly to construction and operations within approved Massachusetts facilities.

The state plan adds labor expectations, including workforce training, quality jobs, and worker benefits, for projects seeking public incentives during construction, operations, and hiring in host areas.

The industry objected to the pause

The Data Center Coalition opposed the pause, arguing developers faced uncertainty just weeks after Massachusetts finalized the exemption program and before the administration reported receiving any applications.

Dan Diorio, the coalition’s vice president of state policy, pointed to industry benefits and cited research arguing that data centers have not clearly driven higher electricity rates for other energy consumers.

Public opinion showed doubts

More Americans oppose than favor a new data center near them, while many say they know little about nearby facilities, local costs, community impacts, and possible energy demands.

Respondents raised concerns about environmental impacts, electricity demand, water use, and utility costs near homes, while some viewed data centers as useful for generating revenue and creating short-term jobs locally.

Massachusetts already has data centers

Data center databases list dozens of facilities in the state, with Boston as a major market and sites operating or proposed in Lowell and Holyoke, among several communities.

Lowell has drawn attention because it hosts the Markley data center, described as the largest facility of its kind in Massachusetts, and a neighborhood concern for residents nearby.

Lowell showed local tradeoffs

Markley did not disclose electricity-use figures, but representatives argued the Lowell site avoids straining state resources and differs from larger facilities built solely for AI companies outside Massachusetts.

The Lowell facility uses between 60,000 and 120,000 gallons of water per day, while some neighbors report a constant hum from building equipment around the data center site.

The next step depends on the rules

The Executive Office of Economic Development paused application intake while agencies review rules, permitting processes, and possible gaps that lawmakers may address if incentives resume under the framework.

The guidance does not replace existing state and local requirements, so zoning, environmental review, building rules, and utility oversight remain part of future decisions for proposed sites in Massachusetts.
