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.

The math behind the comparison
  1. TeraWulf Cayuga Lake High Performance Computing Data Center Campus, capacity: 300 MW.
  2. New York City (NYISO Zone J) summer peak demand, actual, 2024: 10,245 MW (2024).
  3. 300 ÷ 10,245 = 0.03 (MW over MW).

How much power it needs, also reported: 200 MW, 2026 (Ars Technica: TeraWulf owns and operates Lake Mariner; Fluidstack will run the center and has contracted for more than 200 megawatts, later expanded to 360 megawatts) .

Jobs once it runs, also reported: 35 to 40 jobs, 2026 (Ars Technica: TeraWulf's 2024 project manager stated full buildout would bring 35 to 40 permanent jobs at a facility drawing up to 500 megawatts) .

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 Tompkins County and Lansing about data centers, on the record with their source. A rule about the area is not a decision about this record.

Where does TeraWulf Cayuga Lake High Performance Computing Data Center Campus stand today?

It is being built; the date it reached that stage is not sourced, only the day a page was read. The newest entry, August 4, 2026: TeraWulf proposes to convert an abandoned coal fired power plant near Cayuga Lake in Lansing into a 300 MW data center, facing lawsuits over environmental concerns. [1]

What has Lansing or Tompkins County decided about it?

Dryden (rated closed): The town of Dryden in Tompkins County adopted zoning changes banning data centers and cryptocurrency mines over concerns about their energy use (reported September 17, 2026, yahoo.com). 1 event is on the county's rows; a rule about the area is not a decision about this record.

What is still unknown about TeraWulf Cayuga Lake High Performance Computing Data Center Campus?

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, where its power comes from, grid connection, how it is cooled.
