Yes. the small local “pole pig” transformers are jellybean commodities, your local power company has scores of them in inventory.
It’s the BIG garage sized ones at the substation that are difficult to replace, they are custom built, long lead time and very expensive.
Your local hospital, etc. has emergency generators that are expected to provide a whopping 100 hours of power a year. It’s by no means certain that even if they are regularly refueled they could run continuously for the several months it would take to rebuild a fraction of the substations in this country.
Would your car last being run 24/7 for a few months?
The power plants at hospitals and hotels are dry-sumped, so the oil can be changed while the engines are running.
There are several diesel generators at the CCCSD treatment plant near Martinez that have been running continuously since early 1993.
Well, I know that the health center bought really heavy duty generators with the idea of a year of power if needed.
Don’t know much about the hospital’s plan. I do know that they are not likely to survive much longer due to the changes in the ACA.
I also know that while the new parts of the hospital are dependent on gas and electricity, the older parts, functional parts, of the hospital are still run on oldfashioned boilers. I think they told me it was run on coal.LOL
