Cal. Plug’s Draft Definition for Tier 2 Go-to-Market APSRoadmap • Tier 2 Advanced Power Strips are recommended to have the following features: 1. Usage Sensing – to provide at least one method to sense and determine consumer utilization and usage pattern; 2. Advanced Power Analysis – to perform advanced power analysis in addition to voltage and current sensing. These power measurement and analysis may include, true RMS power, power factor analysis and other load signature detection. 3. Control Algorithms - to perform automated power management of connected devices based on data and information acquired;

Workpaper Methodology: Baseline 8 �Baseline methodology q The M&V approach used Cal. Plug’s approved method q PC APS devices and software were modified to execute the M&V approach Title 3/5/2021

Workpaper Methodology: Baseline 9 �Baseline data collection q q A field trial was conducted at (51) university PC workstations for an average of 13 days. Metered data (seconds) � Date & Time (local) � Mains power level (voltage) � Connected equipment current consumption � Connected equipment power use (W) � IR signals determined by the IR sensor on the Tier 2 APS � Count down timer settings of the Tier 2 APS device � Mechanical relay logged state of the Tier 2 APS � Energy saved - cumulative watt hours � Energy saved - instantaneous watt seconds � Energy used - cumulative watt hours � Energy used - instantaneous watt seconds Title 3/5/2021

Workpaper Methodology: Measure 10 �Measure data collection q Raw data was compressed from 1 sec intervals to 90 sec intervals �Measure methodology q q q Title Energy savings calculated using the simulated control state of the baseline consumption Simulation models the actual control strategy by monitoring user activity, computer activity, and power levels Savings are calculated by assuming a low-power sleep state when user activity is non-existent for a certain amount of time, simulating actual APS control strategy 3/5/2021
