- city limits, U.S. Census Bureau, on a town level record
- county boundary

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.
- Buildings
- 2 buildings zoning filing, verified October 27, 2026
- Power it would draw
- 100 MW the developer's figure About 1 percent of New York City's summer peak demand in 2024.
- Who leads it
- Panattoni Development Company as stated by the source
- Undisclosed in public filings
- Land, Water, Who would use it, Jobs once it runs, Tax each year
The math behind the comparison
- Panattoni West Roseville Innovation Center Data Center Proposal, capacity: 100 MW.
- New York City (NYISO Zone J) summer peak demand, actual, 2024: 10,245 MW (2024).
- 100 ÷ 10,245 = 0.01 (MW over MW).
Sources:
- Panattoni Development Company (opens in a new tab)
- NYISO, 2025 Load and Capacity Data Report (Gold Book) (opens in a new tab), Table I-4a, Baseline Summer Non-Coincident Peak Demand, Historical and Forecast, page 26, Zone J, 2024 row (2024)
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.
What was decided

Regional grid context
This site is in the WECC California (CAMX) regional power market. 2024 to 2025 wholesale price effect: 8.6 percent (+$3.70 per MWh, 2024 to 2025), modeled wholesale price effect, Dallas Fed WP 2606r1, third party estimate. 2028 projected wholesale price effect: 17.2 percent (+$6.96 per MWh, 2028 projected), modeled wholesale price effect, Dallas Fed WP 2606r1, third party estimate.
What researchers have found
These studies measure different things. Some model wholesale market prices. Some measure what households actually paid. Some model what would happen under a policy change. The record shows each one as the authors stated it and does not rank them.
