How to read this page. Every fact links to the source it rests on; a number in brackets is its place in the source list. A figure no source gives reads Not disclosed, and nothing is estimated. Where sources give different figures, each is shown with who gave it, and another source's figure never stands in for the record's own. Entries are added and never overwritten; corrections are listed under What happened.
What is known
Each figure as its source gave it. The number in brackets is its place in the source list.

The math behind the comparison
- Iron Mountain Western Pennsylvania Data Center (WPA-1), capacity: 21 MW.
- New York City (NYISO Zone J) summer peak demand, actual, 2024: 10,245 MW (2024).
- 21 ÷ 10,245 = 0 (MW over MW).

A comparison is arithmetic on two published rows and is never a new fact (how comparisons are made).

A blank value cell means not disclosed by any source on file; a blank basis cell means the source gave the figure without saying on what basis.
The developer's figure is what the company said; what a permit allows is the ceiling a permit sets; measured means observed. Water is in gallons a day or a year, whichever the source stated; a tax claim given as a range shows both ends, each linked to the source that gave it.
Still not public, and where it would show up
The record adds each the day a source gives it. Why these documents.
- Water use A state water right filing or a water supply agreement.
- Who would use it A lease announcement or a tenant named in a filing.
- Jobs and tax An incentive agreement, a county's economic development filing or a fiscal note.
