As someone who pays attention to Texas energy rates, I'm gonna call BS on atleast the TX portion of this as rates are at multi year lows. Here are the current rates (1 year contracts):

- Oncor (DFW) 11.6 kwh - Centerpoint (Houston) 10.8 kwh - AEP Texas Central 11.2 kwh - AEP Texas North 11.8 kwh - Texas-New Mexico Power 12.5 kwh - Lubbick Power and Light 12.5 kwh

Not sure how this aligns with new datacenter builds but you can buy power cheap currently.
