A bill for an act relating to customer classes for large energy use facilities, and including applicability provisions.

This bill creates a separate billing class for large energy use facilities in Iowa that consume 20 megawatts or more (primarily industrial facilities under NAICS code 518210). It requires utilities to establish distinct rates for these facilities that directly assign their service costs and prevent shifting those costs to other customers. The utilities commission must review proposed rates to ensure they don’t unfairly increase costs for other customers or undermine grid reliability. The rules apply only to facilities built or expanded on or after January 1, 2027.
