Sonoma Clean Power\u2019s board of directors Jan. 9 adopted rates for its community choice aggregation program. The rates are projected to save households and businesses an average of 2-3 percent on monthly electricity bills compared to remaining a Pacific Gas & Electric customer. \t\u201cFor well over 99.5 percent of the population of this county,\u201d said Sonoma Clean Power chief executive officer Geoff Syphers, \u201cthis is a better deal.\u201d \tThe charge for power on bills actually is to be 5 percent less than what PG&E charges, Sonoma Clean Power consultant John Delassi told the board. However, after adding in distribution fees and surcharges collected by PG&E total actual savings will be narrower. \tPG&E does not comment on proposed community aggregation programs. \tWith rates adopted, Sonoma Clean Power is set to begin service in May. \tBy doing so, it will join neighboring Marin County in offering power that\u2019s purchased under the public purview instead of by investor-owned utilities. \tConstellation, a subsidiary of Chicago-based Exelon, with California plants owned by IHI, is to supply 85 percent of Sonoma Clean Power\u2019s electricity initially. Another 15 percent is expected to come from the local Geysers geothermal resource area operated by Calpine. \tUnder the program, customers in unincorporated areas of the county, as well in the cities of Cotati, Santa Rosa, Sebastopol, Sonoma, and Windsor, are to be automatically enrolled in the program in waves beginning in May unless they opt out. \tIn the first year of operation as many as 20,000 are expected to be enrolled, eventually growing to as many as 120,000 by 2017. \tCustomers are to be placed into a default energy supply program that will provide power that\u2019s 33 percent renewable unless they choose Sonoma\u2019s \u201cEvergreen Energy\u201d supply, which is to be 100 percent renewable. That will entail paying about 20 percent more than what customers pay PG&E. \tThe rate structure also provides continued net metering for customers with solar rooftops. \tUnder the program, PG&E will distribute electricity from its infrastructure, but no longer provide it to customers enrolled in Sonoma Clean Power. \tSyphers pointed out that Sonoma Clean Power plans to enter additional power supply contracts as more customers enroll, including a feed-in tariff program yet to be developed. Its goal is to support developing local renewable energy projects, he said. \tSonoma Clean Power in February is set to begin notifying residents and businesses in the county of the coming switch in power providers this May.
