Using energy efficiency to help address electric systems reliability: an initial examination of 2001 experience

This paper presents the highlights from a study of “reliability-focused energy-efficiency programs” implemented for the summer of 2001. We define these types of programs as those that were specifically designed, modified, or rapidly enlarged to address electric system reliability concerns. After first describing the methodology of the project, we present the results of a 50-State Screening Survey, followed by a description of 22 reliability-focused energy efficiency programs identified and selected as “case studies” in this project. We then discuss examples of three other different types of energy efficiency policy responses that were taken to address reliability concerns. Finally, we conclude by providing some preliminary aggregate impact estimates and outlining some lessons learned during the 2001 experience.
