Do y’all have a generator? A well-prepared mutual friend of ours suggests that would be an excellent precautionary purchase at this time.
FYI — for people considering gensets:
If power becomes erratic in reliability, please purchase and install (or have an electrician install) a proper transfer switch. There’ nothing you want to do less than allow power to feed back into the grid. Burns up your generator, and presents possible lethal dangers to linemen working on power in your neighborhood.
As for gensets: I like diesels. The slower the diesel, the better. Any 1800 RPM diesel is MUCH better than these 3600 RPM gasoline gensets - the slow-speed diesels will last 10K hours or more with care.
I’ve yet to see any of the gasoline consumer gensets last more than about 500 hours, even with care. They’re just not built for a lot of use - they’re built for erratic use with light loads.
The other nice thing about diesel gensets is that the fuel can last in storage for years. Gasoline varnishes pretty quickly now, but diesel fuel keeps for years. Just put some biocide into the fuel every so often, keep a filter on the fuel tank output line, drain off any water that collects and you’re good to go.
