Print Officials at San Diego Community Power think San Diego Gas & Electric is manipulating rates to discourage customers from joining the soon-to-launch community energy program that will cover five cities, and have complained to the utility and the California Public Utilities Commission. SDG&E officials deny the accusation, saying they are relying on the appropriate formula they are authorized to use to calculate rates for this year. The dispute is expected to be resolved Thursday when the CPUC’s commissioners are scheduled to vote on a pair of competing proposals. “We’re not trying to pick a fight,” said Bill Carnahan, interim CEO of San Diego Community Power, the community choice energy program that will offer an alternative to SDG&E when it to comes buying power for customers in San Diego, Chula Vista, La Mesa, Encinitas and Imperial Beach when it begins to accept customers later this year.
