Where each number came from

Read this before quoting a figure. We re-read every source every week, but a weekly read of an unchanged file is not weekly data. These have not moved in a while: ERCOT last changed 2026-06-11 (9 identical reads since). Those rows are exactly as current as the ISO's own published file, and no more.

Compiled from each ISO's own published interconnection queue report. Queue position is not a permit, a contract, or a guarantee that a project will be built; most projects in every queue are eventually withdrawn. Figures are reproduced as published, are provided for informational purposes only, and carry no warranty of accuracy or completeness. Always verify against the ISO's own report before relying on any figure.
