Anthropic Barber Lake
Being built
Anthropic Barber Lake is an AI data center in Colorado City, Texas, developed or operated by Cipher Mining for Anthropic. Satellite imagery shows nothing running yet, against 207 MW planned.
U.S. average: 18.2¢ (+3.4%).
Statewide context, not this project’s effect: prices move for many reasons. Source: U.S. Energy Information Administration.
Satellite figures are Epoch AI estimates from imagery of buildings, cooling and power equipment; about 80% fall within a factor of 1.4 of the true value.
- Apr 30, 2027ScheduledSatellite analysis by Epoch AI · 207 MW planned
Building 1 Phase II is operational: 207 MW total critical IT (300 MW gross). Phase II adds 39 MW critical IT (see Cipher 2025-11-20 PR). We estimate ~Apr 2027, about 3 months later than the ~Q1 2027 target, based on construction progress.
- Dec 30, 2026ScheduledSatellite analysis by Epoch AI · 168 MW planned
Building 1 Phase I is operational: 168 MW critical IT power (244 MW gross), running Google TPU v7 (chip type inferred, tagged likely). We estimate ~Dec 2026, about 3 months later than the disclosed target, because the site is shell-complete but not yet energized as of the Jul 2026 image. Disclosed target: Cipher 2025-09-25 PR states the 168 MW critical IT load is "expected to be delivered by September 2026."

Building 1 shell is complete, with rooftop units installed, and most air-cooled chillers in place in a ground yard to the north. Most of the 120 backup diesel generators are also in place. Substantial progress since Nov 2025, still under construction and not yet energized.
