ID S1368

"New large load" is defined as electrical service requiring 30 megawatts or more increase within any consecutive 36-month period, for service contracts entered on or after July 1, 2026

Public utilities must obtain Idaho Public Utilities Commission approval for service contracts with new large loads, with the commission required to approve or deny within 180 days of filing

New large load customers must fund their share of generation, transmission, substation, and distribution infrastructure investments that would not otherwise be required by the utility

The commission must ensure new large loads do not cause rate increases for existing utility customers and must protect other customers against default by large load customers

Entities cannot circumvent the 30-megawatt threshold by artificially splitting loads among multiple service entrances or meters; the bill takes effect July 1, 2026 as emergency legislation
