A coalition of community choice aggregator advocates urged that investor-owned utilities not be freed from regulatory rules when evaluating a competing community aggregator\u2019s services. One of the issues is the source of funds used to cover private utility compliance plans, according to a Sept. 10 brief filed with the California Public Utilities Commission. The aggregators\u2019 coalition objects to the utilities\u2019 arguments that ratepayers should fund those efforts. \u201cAmong other reasons, the inherent market power advantages of [investor-owned utilities], of which the IOUs\u2019 shareholders are beneficiaries, justify shareholder funding of the audits,\u201d the coalition argues. The community choice coalition includes the Marin Energy Authority, the San Joaquin Valley Power Authority, South San Joaquin Irrigation District, Monterey Regional Waste Management District, City of Santa Cruz, and the Alliance for Retail Markets.
