• Southern California Edison (SCE) is an Edison International company

• One of the nation’s largest electric utilities

• More than 130 years of history

• Headquartered in Rosemead, California

• Regulated by the California Public Utilities Commission (CPUC) and the Federal Energy Regulatory Commission (FERC)

• 50,000 square miles of SCE service area across Central, Coastal, and Southern California

• 15 million residents in service territory

• 5 million customer accounts in 445 cities and communities

Our Grid

To deliver power safely, reliably and affordably, we monitor and maintain a vast electricity system.

730,000 Transformers

119,000 Miles of Transmission and Distribution Lines

4,600 Circuits

1.5 Million Poles

Strengthening and Modernizing the Grid

• Infrastructure reliability – updating underground

cables, poles, switches, and transformers

• Wildfire mitigation – hardening infrastructure,

bolstering situational awareness capabilities, and

enhancing operational practices

• Transmission – connecting renewables, installing

new substations, and updating lines

• Grid readiness – updating the grid for impacts

from new technologies

• Long-term energy policy – supporting energy

storage, electric vehicles, and renewables

SCE plans to spend more than $5B each

year to maintain, improve, and harden

its infrastructure.

SCE’s investments support safe, reliable, affordable, and clean energy for our customers

2019 Capital Investments

179 miles of underground cable replaced

502 miles of overhead conductor replaced for public safety

16.4k distribution poles replaced

4.3k transmission poles replaced

71 underground structure replacements

PATHWAY 2045SCE’S vision to help California achieve a carbon neutral future

Carbon neutrality is achieved through deep decarbonization of

electricity, transportation and building electrification,

and the use of low-carbon fuels

Meeting California’s Climate Change Goals

• SCE filed its second Wildfire

Mitigation Plan in February 2020

• It builds on the progress made

in 2019 to reduce the risk of fire

ignitions caused by utility

infrastructure

• SCE crews will continue to work

to install hi-tech wildfire

mitigation tools and

technologies to make

communities safer, more

resilient, and to help reduce the

number of Public Safety Power

Shutoffs (PSPS)

Addressing Wildfire Risk

• De-energizing power lines to prevent ignitions

• Used during elevated fire conditions

• Primarily impacts circuits in high fire risk areas

• Use of multiple methods to notify people in affected areas before, during and after a de-energization event

What is Reliability?

• In simplest terms:

Having dependable electricity when you need it.

• Outages:

• Maintenance outages (aka planned outages)

• Repair outages (aka unplanned outages)

• Sustained Outage = An outage lasting > 5 minutes

• Momentary Outage = An outage lasting ≤ 5 minutes

9

Major Event Day (MED) : A day in which the daily system SAIDI exceeds a threshold value. For the purposes of calculating daily system SAIDI, any interruption that spans multiple calendar days is accrued to the day on which the interruption began. Statistically, days having a daily system SAIDI greater than a threshold value are days on which the energy delivery system experienced stresses beyond that normally expected (such as severe weather).

Public Safety Power Shutoff (PSPS) : An operational protocol that SCE implements under extreme weather conditions in order to minimize the threat of wildfires and keep communities safe from potentially dangerous situations. These types of sustained outages are temporary and usually involve situations where high fire areas are experiencing adverse weather or public safety is at risk.

*”Exclusions” are days which utilities are allowed to remove from their metrics because the outages on those days were caused by a severe acts of nature.**In the columns showing “Rank,” lower numbers indicate poorer performance.
