Who provides Idaho's plans
Every plan here comes from PacifiCorp (Idaho) — a limit of what has been indexed, not a claim that it is the only provider in Idaho. How each of its plans is built, and what changing between them saves, is set out on PacifiCorp (Idaho)'s own page.
What the Idaho figures do not cover
Only one utility in Idaho has been indexed so far, so the ranges above are not statewide. A household served by another provider will not find its plans here yet.
