Every atlas has holes. Almost none of them publish the holes, so the next person repeats the search. This page is the list: what is missing, what was actually attempted to find it, and what single action would close it.
Nothing is listed here that was not actually tried. A suspicion that data is missing is not a gap. Read together, these entries are the atlas's argument about what a city is allowed to know about its own grid — and they are the honest precondition for any roadmap, because a roadmap built on data that does not exist is a wish.
Three of these gaps are closed by one person doing two minutes of work in a browser — a bot challenge clicked, a federal docket opened, a permissions email sent. They are listed beside the structural ones deliberately, because the difference between an absent fact and an inconvenient one is exactly what a register like this is supposed to make visible.
The rest are not so easy. Massachusetts publishes how much generation a distribution circuit can accept and never how much load. Twenty of twenty-five data centre buildings publish no power figure. The Commonwealth stopped printing per-company utility statistics after 1922 and never printed a peak-load table at all. Federal peak data merges New England with New York. Each is small on its own; together they describe a public record built to answer questions about supply, at a moment when every hard question is about demand.
If you can close one of these, the entry says what to do. If you find a gap this register is missing, that is a contribution — see the charter.
