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is not a permit, a contract, or a guarantee that a project will be built; most projects in every queue are eventually withdrawn.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.
