A consortium of private developers has won regulatory approval in Massachusetts for a $120 million modular data center campus expansion designed to meet surging cloud and AI demand. The project will deploy next-generation cooling infrastructure, waste-heat reuse systems, and a structured workforce development program for local construction trades.
Background
Massachusetts has been actively positioning itself as a competitive data center destination. In November 2024, the state legislature enacted a 20-year sales and use tax exemption for qualified data centers, covering equipment, software, electricity, and construction costs, according to the state's Executive Office of Economic Development (EOED). To claim the exemption, a facility must meet minimum thresholds of 100,000 square feet, a $50 million investment within ten years, and 100 jobs maintained in the state.
The regulatory push followed mounting demand signals. According to a McKinsey & Co. analysis, demand for data center capacity in the United States is projected to more than triple by 2030 from current levels. At the same time, Massachusetts has faced growing scrutiny over existing facilities. Lowell residents filed the state's first lawsuit against a data center operator in April 2026, challenging air permit approvals for diesel generator expansions and raising environmental justice concerns about noise, emissions, and cooling tower mist in residential neighborhoods.
Project Details
The approved expansion will use modular construction methods, in which prefabricated structural and mechanical systems are assembled off-site before delivery and installation. Industry data indicates modular approaches can compress construction timelines from a conventional 24-36 months to 12-18 months for comparable facility types, according to construction industry statistics tracked by The Network Installers. The project's next-generation cooling infrastructure moves away from water-intensive evaporative cooling-a design choice that addresses state environmental thresholds. Under Massachusetts' Water Management Act, data centers using large-scale evaporative cooling can trigger permit requirements for withdrawals above 100,000 gallons per day, according to the Massachusetts Department of Environmental Protection.
The campus expansion also incorporates a waste-heat reuse component to redirect thermal byproducts from server operations, reducing net energy consumption. A 2026 study on digital twin-based cooling optimization demonstrated energy savings approaching 30% through advanced cooling control strategies, according to research published on arXiv. The workforce development program embedded in the project targets local construction labor, addressing a broader national shortage. Industry analysts note the U.S. data center sector will require nearly half a million new workers by 2027, with electricians, HVAC technicians, and commissioning engineers among the most in-demand specializations.
For comparison, the largest planned data center campus in Massachusetts-a multi-billion-dollar project near Westfield-Barnes Regional Airport projected to eventually span 2.7 million square feet across up to 14 buildings-is expected to support between 1,800 and 2,000 construction jobs over an eight- to ten-year build period, according to the Westmass Area Development Corp.
Outlook
The EOED must formally certify the campus before developers can claim tax exemption benefits; as of early 2026, EOED had not yet released a standardized application form for certification, according to the agency's published guidance. Environmental permitting under the Massachusetts Environmental Policy Act and air quality plan approvals from MassDEP remain required before construction can begin. Advocates at the Conservation Law Foundation have called on state regulators to add mandatory energy and water usage disclosures to the certification framework, arguing current draft regulations contain no efficiency requirements.
