PG&E SmartAC Evaluation

Jun 2, 2012

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 involves the installation of programmable communicating thermostats (PCTs) and/or switches in households and small/medium businesses with central air conditioning (CAC). When a SmartAC event is called, the control devices limit the duty cycles of CAC units or adjust thermostat temperature settings, thereby reducing demand.
