The change ledger
What changed in the connection queue
NESO publishes the connection registers as a file that overwrites itself. We read it every Tuesday and Friday, keep every copy, and print the difference, project by project. Nothing here is inferred from the numbers; it is the register on one day against the register on the day before. The column headed "our reading" is ours, and it can be wrong.

Where this can be wrong
The ledger began on 25 August 2026. Nothing that happened before that day is here, and the first capture is a baseline rather than a report. A change of applicant is printed whether the register renamed a company or a different company took the position; the reading column separates the two by comparing the names with their punctuation and legal suffix removed, which is a rule and not a check against a filing. A change of connection point may be a move, a correction, or a project identifier reused for something else, and the register does not say which; Buccleuch Estates moving from the Scottish Borders to Suffolk in one capture is the standing example. A gate 2 flag that appears in one capture and vanishes in the next, as Pencloe did between 28 August and 4 September, is printed both times, because both readings are what NESO published. Where the register is wrong, this page is wrong with it, and it stays wrong until the register corrects itself. If you know better, tell us.
The queue tool is rebuilt from the latest capture with every deploy, so the applicant table, the gates and the dates on the map are the same rows this page reads. The same list by email, once a week, is being built; nothing has been sent yet.
