What this page is18,755 rows held · newest sealed read 2026-08-29

This page is not part of the subscription. Over 79 days of collection this queue produced 1 named mover. We keep the dated copies and this page stays here, but we are not selling it, and the weekly file does not include it.
605 power projects in Massachusetts sit in the newest copy we hold of this waiting list: ISO-NE.
We hold 31 dated copies covering Massachusetts, the first from 11 Jun 2026 and the most recent read on 29 Aug 2026, and 18,755 dated project rows inside them.
Nothing in Massachusetts changed between our newest copy and the newest copy at least a week older than it (22 Aug 2026 → 29 Aug 2026). The table above is the most recent set of moves we do hold, and every row names the two dates it sits between. We do not answer this with our last two copies any more: the newest two we hold are ISO-NE 1 day apart, and finding nothing over one day is much weaker evidence than finding nothing over a week.
The biggest single project in Massachusetts in the newest copy is 345 kV AC line at 1,600 MW.

Real rows out of our sealed copies

These are rows we read out of dated copies we keep ourselves. The live source shows today only, so once a row moves, what it said before is gone from the place you would go to look.

Who published the data on this page

Every row on this page was published by a grid operator, not by us. Written out in full, they are ISO New England. We keep dated copies of their public queue files; the projects, the names and the wording inside those rows are theirs.
This file uses material published by the California ISO.

Their terms say "Most of the materials", not all. This file does not claim the Public Queue Report is inside that "Most".

What this page cannot tell you

An ISO-NE move on this page is never a status change, and that is our fault rather than a gap in ISO-NE's file. ISO-NE does publish a status on its rows. We save the wrong column out of the file, so the status is empty on all 54,162 ISO-NE rows we hold and no page here can see a status change. We are fixing our end. Size and in-service date are read correctly and are what an ISO-NE move here is made of.
The operators write the same fuel differently — Solar, SOL, SUN and S all appear for the same thing. The fuel column is our reading of their labels, not their own count, and a label we are not sure of is shown as not clear rather than guessed at.
A move here means two dated copies of the same public file disagree. It is not a decision, an approval, or a filing. If you need to know why a project moved, the operator is the place to ask, not us. Email operations@ustechautomations.com and we will send you both dated copies so you can check ours.

See the file before you pay

You do not have to take our word for what is in the file. Here are 17 rows of the real thing, carrying all 9 of its columns, cut out of the dated copies we sealed ourselves. Nothing in it is made up and nothing in it is tidied up.

Open the 17 rows as a CSVA plain spreadsheet file. It saves to your machine rather than painting itself into a browser tab, and it opens in Excel, Numbers or Google Sheets.
The same 17 rows as JSONThe same rows again, laid out for reading with code.

What arrives after you pay: a person emails you the whole file as a CSV — the same plain spreadsheet as the sample file above, not a login and not a web page — within one working day of your payment.

What you would be paying for: $49 a month, billed monthly, for dated what-moved files of the California ISO interconnection queue only. Not the Southwest Power Pool, not ISO New England, not the New York ISO, and not a four-queue blend. One file a week, built from daily seals. A week with no tracked-field moves is still sent: added 0, removed 0, changed 0, plus the two content hashes of the workbooks compared. This file uses material published by the California ISO. Copyright © 2026 California Independent System Operator. All rights reserved. Their terms say "Most of the materials", not all. This file does not claim the Public Queue Report is inside that "Most". Cancel any month by email, with no account to close and no notice period. After you pay, a person emails you the first California ISO what-moved file as a CSV within one working day, then a new one every week for as long as the subscription runs. Each file names the two sealed dates compared. If we could not collect that week, the file says so rather than repeating itself.

These 17 rows are a slice of the file, not the whole of it. What we cannot show you here is how far back it goes: that is the part you are paying for.
