In brief

What makes it notable.

  1. A bitcoin site converted to AI data halls, with 200 MW gross and 102 MW critical IT online today and 438 MW of critical IT contracted, as two 168 MW buildings deliver from late 2026 into the first quarter of 2027.
  2. Power comes through the inherited NYSEG Kintigh 345 kV interconnect (former Somerset coal) in NYISO Zone A, plus a roughly 90 MW NYPA Niagara hydropower allocation executed in 2022.
  3. One deployed cluster runs more than 9,000 AMD Instinct MI300X GPUs with Arista Ethernet, and NYISO has approved an added 250 MW toward 500 MW.
