This study evaluates the changes in electricity usage of customers participating in San Diego Gas and Electric Company’s (SDG&E) Peak Time Rebate (PTR) pilot in 2011. The pilot was undertaken to gain experience on the operational aspects of and customer response to such a program, with a view toward expanding to system-wide PTR (also referred to as “Reduce Your Use Rewards”), with automatic enrollment of approximately 1.2 million residential customers in 2012. Under PTR, consumers receive bill credits for reducing usage during certain hours on a limited number of event days, which are announced on the day prior, but face no financial penalties if they decide not to, or are unable to respond. This report describes an evaluation conducted to measure the extent that participating customers succeeded in reducing their event-period usage during the pilot.
