The math behind the comparison
  1. Prometheus Hyperscale Natrona County Data Center, capacity: 1,250 MW.
  2. New York City (NYISO Zone J) summer peak demand, actual, 2024: 10,245 MW (2024).
  3. 1,250 ÷ 10,245 = 0.12 (MW over MW).

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

Acts of Natrona County and the cities in it about data centers, on the record with their source. A rule about the area is not a decision about this record.

Questions about this project

7 questions answered from the record

Answered from the rows on this page.

How big is Prometheus Hyperscale Natrona County Data Center?

The record has one measure of its size: 1.25 GW (third party estimate, wyomingnews.com (opens in a new tab)). Its acreage is not disclosed.

Who is building Prometheus Hyperscale Natrona County Data Center?

Prometheus Hyperscale is the developer. No construction contractor is named on the record yet.

Who will use Prometheus Hyperscale Natrona County Data Center?

Not disclosed. No source on file names a tenant, says whether the site is single or multi tenant, or states what it is for. The record keeps the use as not disclosed until one does; see Who it serves.

How much power and water does Prometheus Hyperscale Natrona County Data Center say it needs?

Power: 1.25 GW (third party estimate, wyomingnews.com (opens in a new tab)). Water: not disclosed by any source on file.

Where does Prometheus Hyperscale Natrona County Data Center stand today?

It is waiting on permits, as reported September 2, 2026. The newest entry, reported September 10, 2026: Commissioners said a formal vote on the Prometheus project remains months away [7].

What has Natrona County decided about it?

Natrona County: Natrona County commissioners discussed the relocation of Prometheus Hyperscale's data center (reported September 4, 2026, trib.com (opens in a new tab)); and Natrona County: Prometheus Hyperscale announced plans to locate its proposed data center entirely within Natrona County (reported September 4, 2026, trib.com (opens in a new tab)). 3 events are on the county's rows; a rule about the area is not a decision about this record.

What is still unknown about Prometheus Hyperscale Natrona County Data Center?

Not disclosed by any source on file: how much water it would use, how loud it would be, jobs once it runs, tax it would pay each year, who is constructing it, how much land, buildings, grid connection, how it is cooled. No missing primary document is listed for this record yet; What the record lacks is where one appears when a person names it.
