Truly mission critical sites don't rely batteries, they have diesel or gas generators, with UPS batteries or flywheels that keep key circuits live until the generators can take over. It's incredibly cost and size prohibitive to build a battery system capable of handling megawatt/hours of load, particularly when it's only going to be used on average a few hours per years. In sparsely populated or geographically difficult areas (islands, semi-frontier areas, etc) that is common. It's not an exact comparison, but Texas has roughly equivalent GDP to Canada. They could certainly match Canada's power reliability if the state government cared to do so. Instead the single-party majority has been content for decades to let major events keep happening instead of making commercial entities meet more rigorous reliability requirements. It would certainly be significantly more cost-effective than eating 100-billion USD disasters.
