Directly re-verified this session via San Diego Community Power's own 'Our Community' page, which explicitly names its six member cities as San Diego, Chula Vista, Encinitas, Imperial Beach, La Mesa, and National City (plus unincorporated San Diego County) — El Cajon is not among them. El Cajon is also not named as a member of Clean Energy Alliance (Carlsbad, Del Mar, Solana Beach, San Marcos, Escondido, Oceanside, Vista), the only other CCA operating in San Diego County. SDG&E is recorded as both the distribution and generation utility.
