KJZZ reports Arizona Electric Power Cooperative would supply wholesale power, Sulphur Springs Valley Electric Cooperative would provide retail service, backup would come from 90 MW of gas generators, and more than 1,000 people have signed a petition against it. The county Planning and Zoning Commission hearing is Dec 9. Baxtel's figures of $50 billion and four 1.5 GW phases are its own reporting.

The buildout in Arizona
We track 2 data center campuses of 100 MW or more in Arizona (1 announced, 1 proposed). Together they announce 3,300 MW at full buildout; weighted by build stage, we expect about 513 MW to be running by 2030. That load lands on the West: Desert Southwest grid. The largest expected load is Tract Buckeye Tech Corridor (378 MW by 2030, announced). Added natural gas burn, from grid-supplied and on-site generation, comes to about 40.2 MMcf/d on an average day.
