4. Residential PLA Program 4 RPP Approach to Calculating UECs: Decision Tree

5. Residential PLA Program 5 Definitions Unit energy consumption (UEC) is the average estimated annual electricity usage (kWh) per unit for a specific product or device. Unit energy savings (UES) is the average estimated annual electricity savings (kWh) per unit for a specific product or device. Coincidence Factor (CF) is the fraction of rated load that is actually connected during peak demand periods. Unit Demand Reduction (UDR) is the average estimated demand reduction (kW) per unit for a specific product or device.
