A residents' coalition · Lake County, Illinois
Lake County is being asked to host 1.2 gigawatts
The T5 campus proposed for Peterson Road in Grayslake would draw more electricity in a year than every household in Lake County combined. We are neighbors asking for the engineering, the water numbers and the tax terms to be public before anything else is approved.

Not a bigger version of the same thing
What a hyperscale campus actually is
Both are called data centers. One runs your inbox, your feed and your streaming queue. The other trains AI models. They are not the same building at different sizes.
Compared with a 30 MW conventional data center, hyperscale campuses use or produce:
Calculated from stated facility ratings at 60% utilization and a power usage effectiveness of 1.25. The 30 MW facility is a representative example, not a specific building. Where the real configuration differs these numbers should be corrected — we would welcome the engineering plans that would allow it.
How the coalition works
Four things we do, in public
Put it on the record
We file written comment before every hearing, so the questions and the answers both survive in the minutes rather than in a hallway conversation.
Check the engineering
Load, water withdrawal, generator emissions and noise are all measurable. We publish our sources and our arithmetic, and we correct ourselves when we get one wrong.
Organize the neighbors
Turnout at a village board meeting decides more than any website does. We tell you which room, which night, and what to say when you get three minutes.
Hold officials to the terms
Incentives, road agreements and water permits carry conditions. We track whether what was promised at approval is what actually gets built.
Read it yourself
Documents and handouts
Everything we hand out at a meeting is downloadable here, with its sources printed on the page. Nothing on this site asks you to take our word for it.
Take action
Stand with your neighbors
The list is ours. We do not sell it, we do not share it, and every message comes from a person on this coalition.
Or do one of these this week
- 1
Speak for three minutes
Public comment is open at every village board meeting. Say where you live, name one specific concern, and stop. Brevity carries.
- 2
Write your trustee
One paragraph in your own words outweighs a hundred identical form letters. We will send you the current addresses.
- 3
Put a sign in your yard
Signs are how a neighbor who has heard nothing finds out there is something to hear about.
