SmartAC Evaluation

Apr 1, 2013

This evaluation documents the ex post and ex ante load impact analysis, methodology and results for PG&E’s SmartAC™ program for residential and small/medium business (SMB) customers. The SmartAC™ program currently involves the installation of load control switches in households and small/medium businesses with central air conditioning (CAC). The program formerly also offered programmable communicating thermostats (PCTs) and there are still a large number of those in operation. When a SmartAC event is called, the control devices limit the duty cycles of CAC units or adjust thermostat temperature settings, thereby reducing demand.
