Queue Ledger

A point-in-time archive of US power-project pipelines — the EIA-860M inventory of every planned, operating, retired and canceled US generator, plus the CAISO and SPP interconnection queues — with every status change and slipped in-service date logged, and the original source file and its SHA-256 kept for each snapshot.

Why

These sources are published as a single current file that is replaced each day or month. The history — when a project appeared, when its operating date slipped, when it was quietly canceled — is lost unless someone captures every version. Queue Ledger does that, so you can answer "what did the source say on date X" with the exact file that was published, and see the change log in between. It is a leading indicator of generation and storage buildout.

CAISO: Source: the California ISO, Public Queue Report. Credit the California ISO when you reuse it; its copyright notices are kept in the raw files.
SPP: Source: Southwest Power Pool, Generation Interconnection active queue. SPP's terms allow copying with citation but require SPP's written authorization for commercial use, so the SPP rows here are for non-commercial use.
