In the guides: What published electricity plans cost, state by state
Who provides these plans
Every plan here comes from Public Service Co of NH — a limit of what has been indexed, not a claim that it is the only provider in New Hampshire. How each of its plans is built, and what changing between them saves, is set out on Public Service Co of NH's own page.
What this does not cover
Only one utility in New Hampshire 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.
