IA SF2249

Requires the Iowa Utilities Commission to create a separate customer class for each "large energy use facility," defined as facilities using 20 megawatts or more that primarily provide data processing or hosting services (NAICS code 518210, which covers data centers).

Mandates that rates, charges, and schedules for these facilities must directly assign all costs of serving to the customer, including transmission, distribution, energy, capacity, and ancillary services.

Requires approved rates to mitigate the risk of other customer classes paying unwarranted costs or having large energy use facility costs shifted to them.

Directs the commission to consider whether proposed rates may result in increased costs or unwarranted risk to other customers, and whether they provide equitable contributions to grid efficiency, reliability, and resiliency.

Applies to electric utility services provided to large energy use facilities constructed or expanded on or after January 1, 2027.
