Your logic on Texas power fails in the face of the exponential disease growth curve.
One half of all disease cases happen in the last round of exponential growth.
There simply will not be enough well or recovered people to run all the natural gas peaker plants when, not if, the disease takes out the control room staff for Comanche Peak and STP nuclear plants.
The simple reason is half of all the power system staff who will get sick, will do so _AT THE SAME TIME_.
This is why the mantra “Flatten the Curve.” It’s not just for the medical staffs.
And because the electric power generation plants are strategic national assets. You simply CANNOT run the the remaining staff to death and risk long term damage to the power plants.
Rolling black outs will be the unavoidable reality we face for several months.
People are freaking out at supermarkets because of the realization that there may be a dearth of truck drivers able or even willing to drive to the stores.
You send staff at the power plants to Mars, in effect. Isolate the facility from intrusion of outside sources of infection. Drop ship essential supplies which are then treated with a portable gamma source for sterilization. A military operation provides security, access control outside the facility.
