Over the past several years, four of the largest investor-owned California utilities have completed more than 50 evaluation studies designed to measure the energy and demand impacts of their demand-side management (DSM) programs. These four are: Pacific Gas and Electric (PG and E), Southern California Edison (SCE), Southern California Gas (SoCalGas), and San diego Gas and Electric (SDG and E). These studies covered residential, commercial, industrial, and agricultural DSM programs and provided a wealth of information on program impacts. The objective of this report is to summarize the results of these DSM evaluation studies in order to describe what DSM has achieved in California, to assess how well these achievements were forecast, and to compare the effectiveness of different types of DSM programs. This report documents the sizable investment made by the California utilities in their 1990--92 DSM programs. Between 1990 and 1992, the four utilities spent $772 million on energy-efficiency/conservation programs. This report also summarizes the realization rates estimated by the 50+ evaluation studies. Realization rates are defined as ex-post net savings estimates divided by ex-ante net savings estimates. Realization rates are summarized for 158 programs and program segments.
