Who provides these plans
Every plan here comes from Interstate Power and Light Co — a limit of what has been indexed, not a claim that it is the only provider in Iowa. How each of its plans is built, and what changing between them saves, is set out on Interstate Power and Light Co's own page.
What this does not cover
Only one utility in Iowa 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.
4 of these plans price by the hour, so their figures are marked lower confidence.
