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

• 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

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.
