The recent innovation of the Public Safety Power Shutoffs (PSPS) is CYA (Covering Your A$$) for electrical service providers.
It is a testament to the failure of power companies (SCE, PGE, etc.) to maintain their infrastructure. No other utility ceases delivery because of the weather.
Electrical power distribution industries have historically been able to deny financial responsibility of their substandard infrastructure and have caused hundreds of billions of dollars of fire damage, all while profiting hundreds of billions of dollars.
