Three electric territories, one gas company
Idaho Power dominates southern Idaho including the Treasure Valley. Avista serves the Panhandle from Lewiston to Coeur d'Alene and Sandpoint, and Rocky Mountain Power covers eastern communities like Rexburg. These are regulated territories. Your address picks your utility, and there's no plan-shopping.
Intermountain Gas is the natural gas utility for nearly every Idaho address we've checked, with Avista handling gas in the north. Water and sewer are municipal: each city runs its own accounts, typically combined on one city bill.
