Same in Arizona, or at least the Metropolitan Phoenix area. I looked at doing solar a couple years ago, and financially it didn’t make a lick of sense at the time, especially with leasing the system. I was told that the utility companies (both of them here) charge a minimum usage fee, and that I was required to keep the utility connected in order to keep the house ‘habitable’ according to codes.
One of the things I do for my employer is keep a weather eye on the power system that feeds the data centre; it has a fully automatic ATS that will switch between generator and line. We have a great big honking UPS system in front of it to provide additional power conditioning and to keep the gear running for a short while if utility power fails until the generator fires up. I suspect the entire rig cost more than my house, but then, my house isn’t wired for three phase.
