Counting the Capacity that Didn't Hatch: The Rate Mitigation Effect of DSM Programs

Minnesota’s electric utility efficiency programs have saved approximately 68,000 GWh of electricity since 1992.1 This conserved energy, which has been called “negawatts,”2 can be considered a system resource analogous to a new power plant. It allows utilities to serve their projected load with available supply resources by reducing demand rather than increasing supply.
