> In California with PG&E which most people have,

Most people in California don’t have PG&E. Most of the land area in the northern 2/3 of the State or so is covered by PG&E, but people and land area aren't the same thing. Southern California Edison alone serves almost as many people as PG&E, and other smaller utilities, including public utilities like LADWP, SMUD, Silicon Valley Power, etc., serve another big chunk of the population.
