In brief

What makes it notable.

  1. A purpose-built, ground-up HPC campus on a 138 kV substation in ERCOT West that was energized in September 2024, with 300 MW of front-of-meter power.
  2. The plan is 300 MW gross and 207 MW critical. The building topped out in April 2026, with first data hall delivery targeted for the fourth quarter of 2026.
  3. Full buildout is targeted for the first quarter of 2027, on a site that began as a bitcoin miner's development and was built new rather than converted.
Deal anatomy
