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

SF 2324 creates a new customer class for large energy use facilities in Iowa, defined as facilities using 20+ megawatts primarily engaged in specific commercial services (NAICS 518210). It requires the utilities commission to establish separate rates and charges for these facilities, directly assigning their service costs and preventing unfair cost-shifting to other customers. The bill mandates that any approved rates must ensure equitable contributions to grid reliability and avoid increasing costs for non-large facility customers. This applies only to facilities built or expanded on or after January 1, 2027.
