Energy Division presents in this report the accomplishments of California's four largest Investor Owned Utilities' (IOUs) [Pacific Gas & Electric (PGE), Southern California Edison (SCE), San Diego Gas & Electric (SDGE) and Southern California Gas (SCG)] energy efficiency program activities for the 2006 - 2008 program cycle. The IOUs implemented energy efficiency programs, either directly or through third parties, designed to improve energy efficiency in multiple market sectors, including residential, commercial, industrial and agricultural, via monetary incentives and other program interventions.
The California Public Utilties Commission directed its Energy Division to evaluate the programs and verify the resulting energy savings and demand reductions. The aggregate results of the evaluation are the subject of this report. Energy Division directed these studies, which were implemented by leading evaluation profesionals and subject to an extensive public review process. The 2006-2008 evaluation is the first time the IOUs' portfolios of energy efficiency programs were evaluated using consistent methods laid out in the California Energy Efficiency Evaluation Protocols and the first time consistent data sets were compiled across IOUs at the technology level. This was accomplished with the cooperation and significant contributions of the IOUs and enables aggregation of savings and other parameters across IOUs, technologies, and programs.
