> Most of my friends spent 35-45k on a generator. Honestly curious: why do you need a generator ? And more to the point, why do "most of you friends" need one (35-45k seems like a huge investment, so it would not be some vanity purchase, right ?) Is that customary where you live, because the grid is unreliable ? |

So, there are two issues:
1. The grid is now pretty unreliable. Georgia Power overall is a great company to work with (compared to say PG&E), but power quality has dropped out the past few years in some areas.
I've had plenty of equipment destroyed due to grid spikes and other weirdness that just didn't occur a few years ago. To give a concrete example: About 3 weeks ago, there were 4 days where literally every arc fault breaker in the house would trip randomly. Why? Because the incoming waveform became super noisy[1], and arc fault breakers are tricky beasts :).
They do notice and fix these things eventually, but the practical time to resolution is days, not hours.
2. We live in an area where the power lines are above ground and trees are aging out. They were planted over 150 years ago, and for a lot of these trees, the lifespan is 125-150 years. So we don't just get taken out by storms, but just nature :)
Georgia power puts new lines underground exclusively, and has moved a lot underground even around us, but our street is the last on the line of service that is both above ground and quite long. As a result, literally any issue/disconnect over about a 2 mile length with tons and tons of old trees, takes us out. This is also partially the reason our power quality sucks so much - any issue is more likely to affect us more than others.
Again - when it comes to outages they are quite fast at repair, having dismantled and removed insanely huge trees, and then repaired the line, almost always within 24 hours.
But it's still annoying. Combined with #1, it's just easier to be semi-off grid (IE monitor grid and swap over when grid is gone or sucking) with a generator or equivalent. Note that because we all own historic homes built in the early 1900's, our electricity usage is is significantly higher than normal just due to lack of insulation, etc. Retrofits only help so much for various practical reasons.
In a newly built home, the generator cost would probably be closer to 15-20k. Battery cost would be similarly half. Nothing to sneeze at, of course, but still.
[1]. I have a very high end fluke power analyzer (a fluke 1775) that i've had for years to debug power quality issues. These are power quality analyzers meant to be used to test service issues like this. I actually bought it when i got tired of having PG&E lie to me in California.
