How we verify

This site is only worth reading if its dates are real. So here is what they mean, what we accept as a source, and what we do when we have not checked.

What a date means

A last verified date is the day a person opened the page belonging to the agency that runs the program and read the current status off it. It is not the day the site was built, not the day a script ran, and not the date printed on the agency's own page. Rebuilding this site moves no dates.

What counts as a source

Yes — the state energy office, its rebate portal, the state comptroller or agency administering the funds, or a US Department of Energy page.
No — aggregator sites, "2026 rebate guide" blog posts, contractor marketing pages, press coverage, and AI summaries. These are how errors propagate, and several of them are currently wrong.

Why rows say Unknown

Unknown means nobody here has checked that jurisdiction yet. It is a published answer, not a missing one. Inferring a status from a press release or a neighbouring state would make the table look complete while making it untrustworthy, and one wrong rebate status costs more than fifty honest blanks.

How often we recheck

Programs in Announced or Waitlist move fastest, so they are rechecked weekly. Open and Paused monthly. Exhausted quarterly. When a row passes its window the page says so on the row itself rather than quietly ageing.

If we ever cannot hold that cadence, the rule is to downgrade rows to Unknown rather than let stale data sit and look current.

When we are wrong

Programs change between checks, and agencies sometimes publish inconsistent information about their own schemes. Anything here can be out of date by the time you read it, which is why every row links to the agency page — that page, not this one, is the authority. Nothing here is tax, legal, or financial advice.
