California's Wildfire Risk
Year -Round Fire Season: Changes to California's climate means that the traditional notion
of a fire "season" no longer exists
Hazardous fuel is building up: 10M acres of land contain ready -to -burn kindling from
nearly 147M trees that have been killed or weakened by drought and bark beetle infestation

Local Community High Fire Risk Area Map
Approximately 25% of SCE's 50,000 square mile service area is located in HFRA.
* Areas within SCE's service area that continue to be designated as HFRA and are in the process of being evaluated to
determine whether they remain as HFRA

Scope of SCE's 2019 SB 901
Wildfire Mitigation Plan
• Enhanced overhead inspections (EOI) on transmission and distribution structures in
HFRA
Inspections . Various existing inspections (poles, switches, circuits, relays, etc.)
• Infrared, Corona scanning and high definition (HD) imagery
J
Q
Z Public Safety Power • Effective communications and engagement with emergency services, customers and
O Shutoff (PSPS) communities
Situational Awareness • Weather stations and HD cameras
a
O
• Hazard tree removal (trees beyond traditional trim zone)
• Vegetation removal at poles
Vegetation Management • LiDAR surveying for transmission, supplemental inspections in HFRA
• SCE plans to implement a 12 -ft tree clearances from distribution power lines
in high fire areas to ensure annual growth will not encroach on compliance distances.
"'
Covered Conductor
• Circuit miles of covered conductor in HFRA
Undergrounding
• Evaluation of certain distribution lines in HFRA for potential undergrounding.
Ln
Other Infrastructure
• Various system hardening activities (e.g., composite poles, current limiting fuses (CLFs),
remote automatic reclosers (RARs), Fast Curve settings)
LL
Z
Mitigations
Studies, evaluations and pilots of alternative technologies
Per SCE's Grid Safety & Resiliency Program (GSRP)

Objective of SCE's Wildfire Mitigation Plan
1. Protect public safety
2. Implement the plan to reduce the risk of potential
wildfire -causing ignitions associated with SCE's
electrical infrastructure
3. Implement measures that further harden SCE's
electric system against wildfires and improve system
resiliency
4. Enhance wildfire suppression efforts by improving
fire agencies' ability to detect and respond to
emerging fires in coordination with utility emergency
management personnel
5. Effectively communicate with customers, community
groups, and other stakeholders about how to
prevent, prepare for, and mitigate the effects of
wildfires

Enhanced Overhead Inspections (EOI)
Enhanced Overhead Inspections
Identify Potential Risks
• In less than 5 months, our crews
completed detailed ground-
based inspections of 400,000+
distribution and transmission
structures in HFRA
• Deploying helicopters and drones
equipped with Infrared,
Ultraviolet, LiDAR and HD image
scanning to perform aerial
inspections of our facilities in
H F RA
SCE's helicopters are equipped with software and high-tech cameras,
like the one shown above, to find potential risk undetectable to the
human eye

Situational Awareness Capabilities
• Hi -Res Data Better Forecasting • High -Definition
• Local Weather Advanced Warning • Remote-controlled
Situational Awareness
• SCE meteorologists
• 24/7 monitoring

Vegetation Management
• 20+ in-house certified arborists
• 800+ pruning contractors with 60 more
crews added June/July 2018
• ;:z� 900,000 trees inspected annually
• ;:z� 700,000 pruned per year;
400,000 trees in high fire risk areas
2019
➢ Continue to remove dead, dying, diseased trees in
H FRA
➢ Remove additional 7,500 which pose a fall -in or
blow-in risk to SCE electrical facilities in HFRA
➢ SCE has implemented a 12 -ft tree clearance from
distribution power lines in high fire areas to
ensure annual growth will not encroach on
compliance distances.

Public Safety Power Shutoff (PSPS)
De-energization to prevent ignitions from powerlines
Used during extreme fire conditions
Primarily impacts circuits in high fire risk areas
Other circuits in non -high fire risk areas may be impacted if
transmission lines are de -energized
Red Flag Warning does not mean a PSPS will be called
Actual frequency of PSPS events will depend on various weather and
environmental factors
Decision will be made with most accurate assessment of real-
time information and situational awareness data
