Proposed-site record

Sentinel Data Center: Project Shirley

Sentinel's Project Shirley remains a proposed Lake County campus. County materials confirm rezoning as the first approval step and preserve later special-exception and site-plan gates; the 500 MW remains planned project/power context, with water and final utility terms unresolved.

Compute Workload

This panel tracks what the facility is for without assuming that every project is AI training, inference, or cloud capacity.

Undisclosed / unknownUnknown

No source-backed workload, customer, hardware, or training/inference allocation is attached to this record yet.

Workload classification remains unknown in the reviewed record.

Public Money

Source reviewed September 9, 2026: the public project trail reports a proposed $5 billion investment and possible future development-agreement terms, but no executed agreement, subsidy, tax abatement, public spending, or infrastructure contribution was established.

Water

Source reviewed September 9, 2026: Lake County's May 20 plan-commission materials require water-management review but do not disclose a water source, cooling method, withdrawal permit, wastewater capacity, or operating-use quantity. Those remain unresolved.

Power

Source reviewed September 9, 2026: Lake County's plan-commission materials identify the rezoning as the first step toward a data center and require later special-exception review; the public project trail cites a nearby 345-kV line and utility verification. The dataset's 500 MW remains planned project/power context, not approved, energized, generation, or data-center IT-load capacity.

No fuel-cell or Bloom Energy source is attached to this project yet.
