Utility and generation supplier

Utility

Southern California Edison (SCE)

Confidence: High (0.9)

Source(s): Incorporated Cities and Counties Served by SCE

Generation supplier

Southern California Edison (SCE) (utility)

Clean Power Alliance's own homepage states it serves '38 communities across Los Angeles and Ventura counties' and names each one individually via its site's community directory; Duarte is not among the named communities. No other Los Angeles/Ventura County CCA serving Duarte was found, so Southern California Edison (SCE) is recorded as both the distribution and generation utility.
