Stop The T5 Data Centerin Grayslake, Illinois

The Grayslake Village Board approved a 472-acre AI data center on Peterson Road with little notice to residents. At 10 million square feet of buildings and supporting infrastructure, it would cover about 350 football fields and would be the second largest facility of its kind in Illinois — next to our homes, our schools and our parks.

A hyperscale data center like the one proposed for Grayslake is not a typical data center. Hyperscale data centers use massive amounts of electricity and water and have long-lasting and potentially dangerous environmental and public health impacts. Here are some potential issues with having a hyperscale data center nearby.

T5's CEO says that T5 Grayslake will "power the smartphones, computers, and technology that we all rely on everyday." That's true of data centers in general, but it doesn't describe this one.

The email and social media we've used for twenty years runs on server racks drawing 8 to 15 kilowatts. An AI rack consists of multi-core GPUs that draw ten times that. That's the actual difference. Assuming 60% utilization, a 1.2 GW campus would consume about 6.3 TWh a year, roughly three times the usage of all 258,000 Lake County households combined [1]. T5’s own FAQ says its first two buildings alone will draw 450 MW [2].

Wondering how hyperscale data centers compare with the data centers that already run our email and streaming? See the two side by side.

Potential Risks

Environmental

  • Groundwater pollution
  • Air pollution from diesel backup generators
  • Sound pollution, both audible and infrasound
  • Light pollution
  • Loss of wildlife habitat
  • Increased stormwater runoff
  • Urban heat island effect/microclimate changes

Economic

  • Increased consumer electricity rates
  • Increased consumer water rates
  • Decreased property values
  • Increased costs for emergency services
  • Increased costs for infrastructure maintenance
  • Increased costs for environmental remediation

Unknown Impacts

Unlike traditional data centers, hyperscale data centers have only been built recently. Long-term environmental, economic, and public health impacts are unknown. This is particularly true of the effect on local ecosystems and wildlife, which require long-term study to assess impacts.
