There are not-for-profile municipal utility operators in California. They form NCPA (Northern California Power Agency), the largest stake holder is SVP (Silicon Valley Power) a.k.a. The City of Santa Clara.

Something a lot of transplants don't learn for years: Palo Alto, Santa Clara, and Alameda are members of NCPA, so you don't pay PG&E, amusingly PG&E pays NCPA for access to its hydro and geothermal.
