Yeah, Oncor isn’t great. They do just enough to keep the lights on for regular customers. But I’m pretty sure large data centers negotiate a higher level of service and purchase power at discounted rates. FB, for example, has a massive data center in the Alliance corridor — check out the link. Those trailer-sized units you see along the outside of the building are enormous diesel or natural gas generators — more than a hundred of them, each about the size of a locomotive. They even have their own electrical substation. The scale and redundancy of that place are unbelievable.

So I’d imagine they could keep everything running for as long as necessary. I remember during the big winter outage a few years ago, they didn’t have any issues at all.
