We have a 20KW natural gas fueled backup generator here at home. Kicks in after 20 seconds of no power. Would something like that be an option for you as a backup?
Sounds like you have a good plan
Bill. Love the generator set-up you have. The weekend property is our hideaway from the big city in case of widespread power-outages, storm damage, or civil unrest and your plan would seem to be perfect for that...plenty of hogs/fish to eat, plenty of wood to burn, and have some good solar lights.
In Dallas as far as our office...potential scenarios to prep for are: storms, chemical spills along the freeway in front of our office, and terrorism. Also in Dallas besides just power for lights and computers, phones, we pretty much must be able to have air conditioning June thru September. Our 3 tower office complex management frowns on gas generators and natural gas would be a no-no too.
So besides just prepping for alternate power sources at our office we must also think about having to move our operation off-site which involves computers/servers, phones, desks, etc...not exactly easy or cheap to throw together.
Of course the doomsday scenario has never happened and I have been in this business 40 years! (1979-2019)
I sware I'm not really that old....lol.
