Yes—data centers can bring valuable property-tax revenue and construction spending, especially to a town seeking a stronger tax base. But residents may still oppose them because the benefits are often narrow or uncertain, while the burdens—noise, land use, heavy electricity demand, water use, diesel backup generators, and major utility construction—are experienced locally and immediately.wri+1

Why opposition is growing

A modern, very large data center can use an extraordinary amount of electricity, and it needs continuous, highly reliable power. U.S. data centers used about 4.4% of national electricity in 2023, and demand is projected to rise substantially; that can mean new substations, transmission lines, generators, and pressure to add generation capacity.energy+1

Common local concerns include:

Does the money help?

It can—sometimes very substantially. Data centers can add taxable real estate, create construction work, purchase local services, and diversify a town’s revenue base through property, sales, and use taxes.wri

The key issue is net benefit, not gross revenue. A project may look lucrative on paper but be a weak deal if the town gives a long tax exemption, bears road or public-safety costs, loses developable land that could host more job-rich businesses, or absorbs infrastructure risks without enforceable developer payments.

A town should ask for a transparent fiscal analysis:

Can a town stop one?

Usually, yes—principally through its land-use and zoning powers—but the answer depends on state law, existing zoning, and whether the applicant has already gained legal rights. Some states are moving to limit local control, so the precise authority must be checked locally.tandfonline

In Connecticut, local zoning remains particularly important; towns have used special-permit rules, size limits, and moratoria while they develop regulations. Recent Connecticut reporting described municipalities restricting facilities above 12,500 square feet, while Bristol created routes for approval only in specified business and industrial zones.ctinsider+2

Lawful ways to act

A town can generally:

A town generally cannot reject a proposal simply because residents dislike it. If the use is already permitted and the developer complies with the applicable rules, an arbitrary denial can invite a lawsuit. The strongest approach is to adopt clear, evidence-based rules before a particular application is decided.

Sensible middle ground

The choice need not be “welcome anything” or “ban everything.” A town can permit data centers only where infrastructure is adequate, make the developer pay full marginal upgrade costs, require public reporting of water and electricity use, limit noise and generator emissions, and insist on a tax agreement that produces a real net gain.

That approach recognizes the genuine fiscal opportunity while ensuring that a private company—not local households—carries the costs created by an unusually resource-intensive facility.brookings+1
