Defining and reporting data on utility dsm programs

The number, scope, effects, and costs of electric-utility demand-side management (DSM) programs are growing rapidly in the United States. Utilities, their regulators, and energy policy makers need reliable information on the costs and performance of these programs to make informed decisions. In particular, information is needed on the ability of these programs to cost-effectively provide energy and capacity resources that are alternatives to power plants. We discuss a new handbook that addresses the need for additional and better information in two ways. First, the handbook (and this paper) contain discussions of the key concepts associated with DSM-program types, participation, energy and load effects, and costs. Second, the handbook offers definitions and a sample reporting form for utility DSM programs. The primary purpose in developing these definitions and this form is to encourage consistency in the collection and reporting of data on DSM programs.
