The ISOs publish today's queue and overwrite it, so no archive exists. We keep a weekly copy. Leave your email and we'll send you each week's changes in solar in California, from new entries to projects that came off the list.

This week's changes · How this is collected

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is not a permit, a contract, or a guarantee that a project will be built; most projects in every queue are eventually withdrawn.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