Improvements to electric efficiency in homes and businesses provide a variety of benefits to both the customers making the improvements and to the electric system as a whole. The most widely recognized are energy savings and system peak demand savings. A much less widely recognized benefit is the potential to enhance the reliability of the transmission and distribution (T&D) system. Efficiency programs can defer T&D investments either passively or actively. “Passive deferrals” typically occur as a result of system-wide efficiency programs. Though such programs are usually implemented for other reasons – e.g. to meet energy savings targets set by legislation or regulation – they can defer load growth-related investments in the T&D system for at least some period of time. “Active deferrals” are those that result from supplemental efficiency programs that are geographically-targeted for the express purpose of deferring the need for upgrades to specific elements of the T&D infrastructure. This webinar, with presenters Glenn Reed of Energy Futures Group and Gabe Arnold from Optimall Energy, explores both innovations in quantifying passive deferral benefits and the evolution of efforts across the U.S. to pursue active deferrals of T&D investments.
