You would be in the area for SDG&E, SCE & LADWP. Farthest south CDWR goes is Riverside, San Bernardino area in the east and Burbank to the west(closer to Castaic lake really than Burbank).
SCE is a good company to work with. I used to be with the former sister company EMOMI (they both fell under the Edison International banner). SCE isn’t big on ot so you’ll just work your normal schedule outside of major emergencies.
I have a former coworker who’s a shift supervisor at the grid control center for SDG&E. Has nothing but good things to say about them as well.
LADWP, if run like their GCC, will be an overtime job. The guys & gals in the GCC can easily double their base salary from ot. Not sure if you’ll be looking for that but those are your main options.
There will be plenty of IPP’s around that area as well if you’re willing to work at an independent power plant. Calpine, AES, and several others all over that area.
If you want a small city or county utility just search the local where she picks up a house.
