By technology

Each ISO uses its own fuel vocabulary, so this table, and only this table, maps them onto shared buckets. Anything we could not map from the ISO's own published coding is counted as unclassified rather than guessed at (1,370 projects). Per-ISO pages show the raw vocabulary instead.

Solar	1,850	217,048 MW (from 1,845 of 1,850 projects)

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 your market, from new entries to projects that came off the list.

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: NYISO last changed 2026-08-13 (25 identical reads since); SPP last changed 2026-09-05 (3 identical reads since). Those rows are exactly as current as the ISO's own published file, and no more.

ISO	We last read	Source last changed	Source
CAISO	2026-09-07	2026-09-07 (changed this snapshot)	source file
ISO-NE	2026-09-07	2026-09-07 (changed this snapshot)	source file
NYISO	2026-09-07	2026-08-13 (unchanged across 25 weekly reads)	source file
SPP	2026-09-07	2026-09-05 (unchanged across 3 weekly reads)	source file

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is not a permit, a contract, or a guarantee that a project will be built; most projects in every queue are eventually withdrawn.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