Project Longhorn (Pacifico Cedar Creek)

Pacifico Energy and BlackChamber's 2,842-acre Bastrop County, Texas campus: 1,326 MW on-site gas plant, air registration caught in the state pause; Anthropic talks unconfirmed.

Air permit pending, paused. The gas plant's air registration, filed Aug. 14, 2026, is pending and falls under the governor's Sept. 2026 pause on data-center permits. No construction is on record; a building filing sets a Nov. 2026 start. Anthropic lease talks are unconfirmed.
