Utility Wildfire Mitigation Strategy September 18, 2019

Discussion questions: Metrics • What is the set of appropriate metrics to understand the drivers and risks of utility-related wildfires? • What metrics can be used to evaluate the effectiveness of WMPs and/or can assist in future learning and adaptation of WMPs? • What additional metrics or metric categories could complete the Sept. 6 submission? 2

Summary of proposed metrics from Sept. 6 submission Exposure Frequency Triggering Capabilities drivers drivers events Response Outcome Lessons learned Wind speed Within HFTD/other Within HFTD/other Response time 1 1 1 and incorporated associated with areas [when FPI is areas [when FPI is to ignitions due to failings in outage, wire- rated as very-high rated as very-high or detections, down, and or higher]: higher]: 2 Response time • # of [energized] • # of utility coordination, vegetation events to wildfires 1 1 and/or equipment wire down events equipment 2 # of National Fire caused ignitions Response time to 3 • # of vegetation Training of Danger Rating 2 coordination with 2 System “Very • # of vegetation personnel, caused outages 2 local agencies Dry” &“Dry” days; including caused ignitions “live drills” • # of equipment # of FPI Time to 3 4 • # of other/animal "Elevated" & failure/other/ deployment of 3 Accuracy of "Extreme" days animal caused caused ignitions firefighters or 3 software and outages relevant measurements to personnel • # of faults on detect high-risk 4 wildfire conditions HFTD circuits associated with contact from object or equipment failures • # of conventional 5 blown fuse events 3

Discussion questions: Data collection and reporting • What data can be collected, measured, and reported accurately today? • What other data might be important to collect and share? • How should metric requirements be incorporated into ongoing reporting? 4
