Inspect overhead equipment in
high fire risk areas for repairs from
the ground and aerially using
drones, prioritizing the highest-
risk structures. Each year,
inspecting portions of
transmission and distribution
equipment that comprise about
99% of wildfire risk.
HIGH FIRE RISK INSPECTIONS & REMEDIATIONS
Inspect, trim and remove trees to
prevent vegetation from coming
into contact with electrical
equipment and potentially
sparking a fire. Tall trees beyond
standard pruning zones that could
potentially fall into power lines are
also assessed and pruned or
removed. SCE also removes palm
trees that may come in contact
with power lines.
VEGETATION MANAGEMENT
Use PSPS as a tool of last resort to
mitigate wildfire risk during
elevated fire weather conditions,
such as strong winds and dry fuels,
by shutting off lines to prevent a
spark from our equipment starting
a significant wildfire.

•Utilities use protection settings on circuits to reduce
damaging impacts caused by excessive current and fault
energy during a fault condition, such as a tree branch falling
on the line or a downed wire
•Since 2018, we have been using faster and more sensitive
protection settings (“fast curve settings”) in HFRAs as part of
a suite of ignition risk mitigation measures
•We initially selected moderate fast curve settings to balance
wildfire risks and reliability concerns. We are evaluating risk
reduction and impacts to refine and adjust these settings. We
are also deploying fast curve setting capability on additional
circuits in HFRAs

The location of your home or business on a circuit and the area of severe weather relative to your
local substation are important factors in determining whether or not you are impacted by a

HOW PSPS CIRCUITS WORK
CONCURRENT EMERGENCY RESPONSE SYSTEM
The extreme weather that creates the need for PSPS can also exacerbate other local
power emergencies. Outages could result from heat -damaged equipment, active
wildfires or from issues with the state’s electrical supply or unrelated emergencies.
SCE Response:
•California Standardized Emergency Management System and Federal National
Incident Management System
•SCE Emergency Operations Center (or virtual EOC as required)
•One or multiple Incident Management Teams activated based on scope of incident
•Incident Support Team available for more complex incidents to assist with
prioritization and resources
•IST directs all aspects of communications and outreach including coordination with
external agencies and first responders
SCE CONTINUES TO REDUCE PSPS IMPACTS ON CUSTOMERS
THROUGH GRID HARDENING AND ENHANCED SITUATIONAL AWARENESS
