Since the late 1980`s, utilities in California have used demand-side management (DSM) extensively to achieve a variety of corporate and public policy goals. This commitment to ene efficiency was encouraged by the establishment of financial incentives for the utilities to acquire demand-side resources. With restructuring of electric and gas markets underway in California, including recent cutbacks by the California utilities in their DSM program efforts, it is timely to review retrospectively the accomplishments of California`s DSM investments. This paper summarizes the results of 50 evaluation studies that assess California DSM programs operating between 1990 and 1992. On average, the programs delivered 112% of the energy savings that were planned, and the typical program realized approximately 86% of the energy savings it was expected to deliver. Thus, the California DSM programs outperformed DSM programs from the 1980s, in terms of more accurately forecasting energy impacts. Among the 50 impact studies, lower realization rates are associated with residential-sector programs, relatively high ex-ante estimates of savings, and significant levels of free ridership.
