As I said in another post, it only takes a couple days without power in our modern society for someone to say "I will spend whatever I can to never have to go through that again".
I was not hit by SCE PSPS, although the area included areas really close to me. What did happen to me in 2019, is 2 different power outages during the year, one which was "several hours" which wasnt "that" bad, and one which was about 2 1/2 days due to someone hitting a utility device hard enough to get the cable wrapped up in their car and pull some out of the ground.
That was in january of 2019, and it was "cold" where I live. "Cold" is mid to low 30s at night, and mid 50s to during the day. During those 2 days, the inside of the house got down to around 60 degrees. We had to throw away all our food, we were sitting here, in the dark, with jackets on in the house. We had cellphones because I had just bought my tesla, so I could charge them during using the USBs in the car. I also used the car USB ports to charge an iPad after it ran out.
I used the hotspot on my phone to get internet for my laptop, and my wife and I were huddled around a laptop watching netflix.. until the laptop ran out of power. The first night was not "that" bad, but by the second day, with no real update from the utility on time frame other than "we are working as fast as we can", I had decided that night 2 was it... after night 2, I told her we would go to a hotel. The power came back on mid day on day 3.
Previously, because I had penciled out the powerwalls as a 12 ish year payback, I had decided that "I didnt need them" as I dont consider this house I am in, "the house I will spend my retirement in". During the year, I decided that I would likely stay here until I retire, even if I dont currently plan on spending my retirement in this house (or maybe even this state). Thats likely about 10 years away, give or take, and I decided that "even if the pay off is 12 years, I am never going through that long without power again, especially since I already have solar on my house".
