Generation supplier

Southern California Edison (SCE) (utility)

Western Community Energy (WCE), the only CCA ever formed to serve inland Southern California, deregistered with the CPUC and dissolved via Chapter 9 bankruptcy in 2021. Its own now-stale website (frozen since its original 2020 launch announcement) confirms its service area was limited to only six Riverside County cities (Norco, Perris, Wildomar, Jurupa Valley, Hemet, Eastvale) and never included any San Bernardino County city. No other CCA was found serving San Bernardino County in this dataset's research. SCE is recorded as both the distribution and generation utility.
