Interconnection queue sentinel
ISO interconnection queues are republished in place — last week's version is simply gone. We have kept a weekly archive, so we can tell you what changed: which projects moved status, shifted commercial-operation date, changed capacity, or left the queue. The paid file covers CAISO only: CAISO's written terms allow reuse with credit, and no other queue we hold carries a written grant, so no other queue's rows are sold. ISO-NE and NYISO snapshots continue and stay readable free on the page, unsold. SPP's material is allowed only outside a commercial publication, so its rows are never in the paid file. Two others are deliberately not collected: ERCOT's robots.txt disallows the paths its queue is published under (stopped 2026-08-05), and MISO blocks a collector that identifies itself — the only way to fetch it was to impersonate a browser, which we will not do to resell the data (stopped 2026-08-07). Both archives stay readable through those dates; neither takes a new snapshot.
Not on sale
Withdrawn 2026-08-24. SPP refused commercial use of its interconnection queue, so we cannot deliver the four-ISO change feed this service advertised. The sealed queue archive we already collected stays readable.
We are not taking new orders for this service, so there is no price and no way to order it here. The evidence we already hold stays readable and is still described on this page.
What you get
- A weekly what-moved file for the CAISO interconnection queue, the one queue whose written terms allow resale with credit
- Status, capacity and in-service-date movement, project by project
- Departures and new entrants, which the live queue page cannot show you
- Each row carries the snapshot dates it was derived from
- No ISO-NE, NYISO, SPP, ERCOT/Texas or MISO rows in the paid file — ISO-NE and NYISO stay free on the page; SPP's terms forbid commercial reuse; ERCOT and MISO archives stay readable through 2026-08-05 and 2026-08-07 but no new snapshot of either is taken
What a sentinel does that a dashboard cannot
Every ISO publishes its current interconnection queue for free, and every ISO overwrites it. A dashboard reads the file that is on the site today; a sentinel keeps the file that was on the site last week, which is the only way the question ‘what changed?’ still has an answer. That is the whole product: we hold the weekly interconnection-queue snapshots, and the sentinel tells you which of the projects you named moved.
Where we stopped collecting, the sentinel says so by name rather than reporting a quiet week.
Specimen status UNKNOWN
The catalog points to a specimen, but its compiled artifact cannot be read. No current proof is asserted.
