It's more that Texas is barely able to operate their grid at 100% of today's capacity demands without noteworthy outages and humiliating 100x/kwH surge pricing events, prior to datacenters requesting another 500% of the capacity they're unable to deliver competently today. And it's not like they can just build five more racks in a datacenter to solve that! One wonders if Texas will pass a bill like Oregon that charges datacenters for the capital infrastructure build costs (new generation plants, new transmission lines, etc.) of their demand — corporate graft as a state ethos is all well and good until you're evaluating Datacenters Per Nuclear Power Plant in serious, rather than comedic, terms.

Have any links to this? I'm not super familiar with Texas's generation or grid.
