AWS Glen Rose Campus (Comanche Peak)

Amazon Data Services, an Amazon affiliate, is pursuing a campus on Vistra property adjacent to the Comanche Peak nuclear plant near Glen Rose in Somervell County, Texas. Somervell County commissioners moved forward with a development agreement in late October 2026, subject to finalised lease terms. Trade reports put the site at about 435 acres and the investment at roughly 5 billion US dollars. The power arrangement is the notable part: ERCOT has recommended conditional approval of a net-metering arrangement between the proposed 1,200 MW campus and the 2,400 MW plant, filed with the Public Utility Commission of Texas as Docket 59399. The proposed energization schedule starts at 100 MW in the fourth quarter of 2027, reaches 800 MW by the fourth quarter of 2029 and the full 1,200 MW by the fourth quarter of 2031. The supply would come under a 20-year power purchase agreement with Vistra. The project has not started operating and approvals are pending, so the 1,200 MW figure is a grid-side load request rather than an operator-stated IT capacity.
