Spot an error? Here's exactly what to do.
Every figure on this site is sourced to an official publication — and if one is wrong, we want to know fast. This page covers what to send, how we verify it, and where the fix lands.
Three things make a report verifiable.
Email [email protected] with the subject line “Correction” and include:
- The page URL — and the section, if you have it.
- The specific figure or claim you believe is wrong, quoted as it appears.
- A link to a primary source that contradicts it — the ICC, the IPA, a utility tariff, ilga.gov, the IRS, or another official publication. This is the part that lets us act: our standard is the primary source, in both directions.
We check the source — then the source wins.
Every report gets reviewed against the primary source. If the source confirms the correction, we fix the affected page and note the change in that page's dated changelog — the same place every update to that page is recorded. If the source supports what we published, we'll reply and explain why, with the citation.
Two honest caveats: a figure that's dated on the page and pending its scheduled review trigger — like a supply rate awaiting its next reset — isn't an error, it's a timestamp. And differences of interpretation about whether solar is worth it aren't corrections either; the numbers are correctable, conclusions are yours to draw.
If your issue is with a solar seller or installer — misleading pitch, contract dispute, bad conduct — that's not a corrections matter for this site; it belongs with the official channels built for it: the Illinois Shines Consumer Complaint Center (877-708-3456), ICC Consumer Services (1-800-524-0795), or the Illinois Attorney General's Consumer Protection Division.
Corrections are the enforcement arm of the sourcing rules.
This process only works because every figure on the site carries a source and a date in the first place. How that sourcing works — and who we are:
