Rural and Small Town Areas
We also serve many small towns and rural areas throughout Northern California, including parts of the Sierra foothills, coastal regions, and Central Valley.
- Los Angeles, San Diego, and other southern cities primarily use Southern California Edison (SCE) or San Diego Gas & Electric (SDG&E) for electricity.
- Sacramento is primarily served by the Sacramento Municipal Utility District (SMUD), although some areas fall under PG&E's service area.
