FYI: Perris fairgrounds data center affects Temecula
FYI, this is 30 miles away from Temecula. On Aug. 26 the Southern California Fair board in Perris signed a nonbinding MOU with Global Stack to study an 8-10 MW data center on the fairgrounds. No one showed up to oppose it. I didn't know about it.

Why it matters: regional load growth is part of how CAISO justifies new transmission lines, and data centers are the fastest-growing piece of that. Global Stack wants up to 70 of these statewide, roughly 500-700 MW in aggregate. UC Riverside's Shaolei Ren told SFGATE that even a 10 MW load can raise rates and force grid upgrades if local SCE circuits are already stressed.
Worth asking what upgrades the Perris site would need and whether cumulative data center load is being counted in regional transmission need assessments. For example, would this add justification for the Golden Pacific Powerlink? Is this being gamed and a bunch of these that no one opposes justifies their transmission lines?
