After reading this, I am seriously considering a built in automatic backup generator. With a very large fuel storage tank, enough for a few weeks at least. Diesel or propane.
Just remember for them to work when needed generators must be tested and maintained. Diesel needs to be tested and treated. Then with propane you could have delivery problems and a tank to hold that much would be large and expensive.
Natural gas has often been thought of as a 100% available fuel but that has not been the case this time around.
After running data centers for many years I had to learn about this stuff.
