Methodology

How we build, verify, and maintain the EV Rebate Finder database. We publish this so anyone can audit the work — what's verified, what isn't, and why we're confident in what we publish.

What's in scope

The database covers active California funding programs for commercial EV chargers. "Commercial" means non-residential — multifamily, affordable housing, fleet, workplace, public-access (retail, hotels, public lots, DCFC corridors), mixed-use, and school/government sites.

We do not include programs for residential single-family chargers (those have their own ecosystem and are out of scope). We do not include vehicle purchase rebates — those are a separate category covered by California's Clean Vehicle Rebate Project. For more on the distinction, see EV vehicle rebates vs EV charger rebates.

The six tiers we track

How we verify

  1. Source-of-truth check. Every program is verified against the administering agency's published page or PDF. We don't rely on third-party aggregators (DSIRE, NREL AFDC) as primary sources — they're useful for discovery but their California commercial detail is shallow and slow to update.
  2. Status flag. Each program carries a status — Active, Between Rounds, Upcoming, Waitlist, or Verify Before Applying. Programs with a recent status change get the verify flag and a direct call to the agency before publishing.
  3. Verification date. Each program shows when it was last individually verified. Programs older than the latest refresh get re-checked first.
  4. Confidence level. Internal field marking how confident we are in the data. High confidence comes from a stable agency page with structured fields. Low confidence requires direct phone/email confirmation.

Refresh cadence

Monthly for the full dataset. Roughly 3–6 hours of manual verification per cycle — going through the long-tail programs flagged for re-check, plus any agency announcements we caught during the month.

Weekly automated polls for federal funding announcements via grants.gov, plus the California Energy Commission funding-opportunities RSS feed. New entries are flagged for human verification before publishing.

Where direct APIs exist (NREL AFDC, grants.gov), we use them as a cross-reference — never as the primary source. The APIs lag the source pages by weeks to months in many cases.

How "program role" tags work

Each program is tagged with a role:

The homepage defaults to direct programs only. Toggle "Include enabling / financing programs" to see the full stack including these adjacent funding sources.

What you should not assume

The database is an orientation tool, not a compliance product. Before applying to any program:
