Can you switch plans in Idaho?
No. Idaho's residential electricity market does not offer retail supplier choice, so you cannot cut the bill by switching plans.
What you can do instead: cut the usage side of the bill. See what each appliance actually costs to run at Idaho rates in our cost-to-run guides, and target the biggest loads first.
