The record, newest first

  1. Viridien published project details: 5 MW to start, up to 21 MW if expanded, air-based closed-loop cooling and a dedicated Bluebonnet power feed. (KWHI, April 1, 2026; Viridien, Oct. 30, 2026)

  2. The Brenham City Council unanimously voted down a reinvestment zone that would have allowed a tax phase-in; Viridien said it would go ahead anyway. (KWHI, Jan. 9, 2026; DatacenterDynamics, Jan. 9, 2026)

  3. CGG Services registered a $50 million, 40,262 sq ft data center building with the state. (Texas Department of Licensing and Regulation (TABS), Dec. 10, 2025)

Conflicts and open questions

  • Under 50 MW.
  • Reported plans call for up to three roughly 40,000 sq ft buildings and moving Viridien's Americas hub from Houston over time.
  • A resident petition opposing the project was reported by DCD.
