T5 Data Centers Defends Grayslake Project as Local Opposition Builds

Key Takeaways

• T5 Data Centers is promoting billions in potential tax revenue from its Grayslake development as residents raise concerns about noise, electricity demand, and land use.
• Record-low data center vacancy and power constraints are pushing more projects into communities outside established technology hubs.
• Approval may depend on credible noise controls, transparent utility planning, and enforceable operating conditions rather than economic projections alone.

T5 Data Centers is defending its proposed data center development in Grayslake, Illinois, by emphasizing the potential for billions of dollars in tax revenue. Local residents, however, are focusing on a different balance sheet: possible noise exposure, pressure on electricity infrastructure, and the risk of higher energy costs.

That tension is becoming familiar across the United States. Artificial intelligence, cloud services, streaming, and enterprise computing are driving demand for facilities capable of operating large clusters of power-intensive equipment. The commercial case for adding capacity is strong. The community case can be harder to establish.

According to CBRE, data center supply across major North American markets rose 36% year over year to 9,432 MW in 2025. Yet vacancy still fell to a record-low 1.4%, while absorption increased to 2,497.6 MW from 1,809.5 MW in 2024. Average asking rates for requirements between 250 and 500 kW climbed 6.5% to roughly $196 per kW per month.

Those figures help explain why T5 Data Centers sees value in Grayslake. Capacity is scarce, customer demand remains high, and sites with viable power access can command substantial commercial interest.

Building supply is struggling to keep pace. CBRE reported that capacity under construction declined from 6,350.1 MW in 2024 to 5,994.4 MW at the end of 2025, with permitting, zoning, and power procurement among the obstacles. Organized local opposition can lengthen that process, particularly when residents believe project benefits are broad but potential disruption is concentrated near their homes.

Noise is one practical concern. Data centers contain cooling equipment, pumps, fans, transformers, and backup generators. Each component can comply with an individual specification while their combined sound remains noticeable, particularly at night when surrounding noise levels fall. Equipment cycling and low-frequency sound can also influence how nearby residents experience a facility.

Technical standards can help establish operating expectations. ASHRAE TC 9.9 guidance addresses thermal conditions for data-processing equipment, while the Uptime Institute Tier Standard focuses on infrastructure resilience and availability. Neither framework, by itself, settles whether a particular sound profile is acceptable to neighboring properties. That requires site-specific modeling, monitoring locations, operating limits, and a clear enforcement process.

Power is the larger issue. Lawrence Berkeley National Laboratory has estimated that data centers could account for 6.7% to 12% of U.S. electricity consumption by 2028. Residents therefore want to know who pays for substations, transmission upgrades, and additional generation needed to serve major projects.

Will a large industrial customer strengthen the local grid through infrastructure investment, or shift costs toward other ratepayers? The answer depends on utility tariffs, interconnection agreements, regulatory decisions, and the timing of system upgrades. A project’s total electricity consumption does not automatically translate into higher household bills, but vague assurances are unlikely to resolve the concern.

Location trends add another wrinkle. JLL reported that 64% of North America’s 35-GW construction pipeline was outside traditional data center hubs. Developers are looking farther afield as established markets encounter limited land, constrained power supplies, and slower approvals. That brings projects into communities with less experience evaluating data center operations.

Grayslake is consequently dealing with questions already confronting municipalities near developments associated with Microsoft, Google, QTS, and other operators. Tax revenue may support schools, infrastructure, and public services, but long-term fiscal projections often depend on valuation methods, incentive structures, and sustained operation.

For T5 Data Centers, winning approval may require more than presenting the project’s headline economic value. Publicly reviewable noise studies, defined generator-testing schedules, utility cost-allocation details, water-use disclosures, and enforceable performance limits could give officials a firmer basis for weighing the proposal. The capacity shortage is real. So is the expectation that communities hosting digital infrastructure receive evidence, not just projections, before accepting its local footprint.
