The California Public Utilities Commission on July 2 started a new rulemaking to continue oversight of the state’s renewable portfolio standards program. The commission will continue to review and monitor renewable procurement plans of retail sellers as well as procurements of investor-owned utilities, assess compliance, and take enforcement action. The new proceeding will consider improvements by adding new elements, and revising procurement methods and tariffs such as utility solicitation and renewable auction mechanisms. California’s RPS targets, originally established in 2002, have been strengthened with the most recent goal set in 2015 requiring retail suppliers and publicly-owned utilities to get 50 percent of their electricity from renewables by 2030.
