SmartAC Ex Post Methodology

Basic analytical requirement for SmartAC impact evaluation is the estimation of a reference load during event periods

2011 evaluation was based on the use of control groups for every test event

Residential estimates were based on the use of SmartMeter interval data with very large treatment and control groups (e.g., 15,000 customers/event)

SMB estimates were based on AC logger data for a sample of customers

Ex post impacts were calculated by comparing the average event day usage in the control group to the average event day usage in the treated group
