PG&E DR Baseline Study

The problem of accurately baselining loads is an increasingly complex problem. This report describes and evaluates the several baselining methods for demand response events. Seven different methods are explored during this study, including Ten-in-Ten and Three-in-Ten with and without adjustments as well as several weather based methods. The findings from this study are that the Ten-in-Ten baselining with an adjustment capped at 40% is the most accurate method for load estimation. Furthermore, capping the adjustment level at 10% leads to improved estimation accuracy.
