Changes between documents
Where two documents print different values for the same project. A large change in a cost estimate can reflect a need being combined with others into one solution, not only a re-estimate; read both pages.

Before relying on any of this
- Names are machine-extracted from PDFs by a language model. Every exported name was checked to be printed in the PDF text; names read only from maps or diagrams are excluded.
- An entry is a name within a transmission zone, not a verified physical facility. The same name in two zones is two entries; spelling variants are merged only when they differ by punctuation, case or a generic suffix such as "Substation".
- role is "new" only where a cited document phrase describes the substation as new or describes constructing it, "existing" where a phrase describes work at it, otherwise "unknown".
- Costs, dates, statuses and loads are the documents' own printed values for the most recent document that names the substation. Each one shipped here is printed on its cited page ("verification": "exact" or "on-page"); values that failed that check are withheld and counted in figures_withheld_unverified. None has been reviewed by a person.
- Zone is the transmission owner whose deck presented the project. PJM-SYSTEM marks names from PJM's own reliability decks, which span zones.
- A printed customer load is the amount a document states for a request. It says nothing about the substation's capability.
