Power & your bill

720 MW of new demand — roughly a city of 576,000 homes.

Large new loads can raise transmission and capacity costs that land on every ratepayer. Residential power in SD is 14.3¢/kWh, up 12.1% 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.
