The story of Poolside Project Horizon (West Texas)
Grid
ERCOT · Behind the meter with the grid kept as backup: on-site aero-derivative turbines with SCR emissions control and battery storage for load balancing, plus grid interconnect redundancy. The 568 acre site on Longfellow Ranch sits next to a major Permian gas hub, and the 2 GW campus is planned in eight phases of 250 MW, the first of which is 250 MW gross with an option on 500 MW more.
GPUs
40K 40,000+ NVIDIA GB300 NVL72 GPUs (CoreWeave, phase 1)

Every figure is one row in the ledger below with its source. Derived rows are pure arithmetic on the rows above (not new claims). Absent lines mean the fact isn't on record yet.

The Texas (ERCOT) grid demand right now: 71.7 GW (EIA-930, 2026-09-27 18:00). Poolside Project Horizon's announced 2 GW would be 2.8% of the grid's current load.

County water status: Moderate drought (D1) in Pecos County, week of 2026-09-22 (US Drought Monitor). Data centers are large water users for cooling; this is the neutral local water picture.
