Power & your bill

40 MW of new demand — roughly a city of 32,000 homes.

Large new loads can raise transmission and capacity costs that land on every ratepayer. Residential power in TX is 16.4¢/kWh, up 7.3% year-over-year. (MW→homes is a rough ~800/MW planning figure.)

Process

Demand a full, public review — not a rubber stamp.

Ask for an independent noise study, a water-and-power impact assessment, enforceable conditions (setbacks, hours, cooling type), and that the record stays open for written comment. Procedural shortcuts have voided approvals elsewhere.

The closest existing grid infrastructure and the municipal water system this location sits in — the same constraints the buildout model screens on (it won't site a campus more than ~2 km from a substation or ~5 km from municipal water). Distances are straight-line to public HIFLD/EPA features, not a metered connection.
