What's happening in Warren County
Facilities here with disclosed capacity draw 44 MW from the local grid. Data-center load on this scale is the single biggest driver of recent capacity-market price increases — costs that flow through to every ratepayer in the service territory, not just the operators.
CyrusOne LLC has the largest presence in Warren County. We resolve project codenames and shell LLCs back to the corporate parent wherever the public record allows, so the table below names who is actually behind each site.
Below: every tracked facility in the county, the active state legislation that names it or its county, and local news. Commissioner vote records arrive in a later release; the placeholders show where that accountability data will land.
Every tracked facility
| Facility | Operator | Status | MW |
|---|---|---|---|
| CyrusOne Cincinnati-Mason CIN3 | CyrusOne LLC | 30 | |
