• 63 Community Resource Centers and 8 Community Crew Vehicles available • Deployed 14,300+ Critical Care Back-up batteries to Medical Baseline customers
IMPROVED PSPS EXECUTION & CUSTOMER SUPPORT
SCE has reduced the probability of catastrophic1 wildfires associated with its equipment by about 85-88% since 2018
Completed in high fire risk areas since 2018

2023 YEAR -END PROGRESS UPDATE
Protecting Public Safety: Public Safety Power Shutoffs
7 • SCE implements Public Safety Power Shutoffs
(PSPS) to temporarily shut off power to some
communities when there is a high risk for
wildfire to prevent the electric system from
becoming the source of ignition
• PSPS is used as a measure of last resort to
protect public safety under dangerous fire
weather conditions, including high winds, low
humidity, and dry vegetation
• Multiple methods are used to notify customers
and stakeholders in impacted areas before,
during and after a PSPS event
• SCE provides resources to support customers
during PSPS and offers several programs and
rebates to help customers be prepared and
more resilient during emergencies
• SCE is working to reduce the impact of PSPS
and is continuing to strengthen the electric
grid to become more resilient in the face of
extreme weather events

SCE’s System Planning Process
8 • Southern California Edison (SCE)
performs annual system evaluations to
address the changing power needs
throughout its service territory
• System capacity plans are developed on
a 10-year forecast based on information
provided by customers and load
forecasting methodologies
• Accurate and timely customer
information is crucial to system planning
evaluations
• Developers should contact SCE as
early as possible to initiate discussions
with planning on power service
needs.
SCE’s Forecasting Process
9 • SCE’s forecasting team is actively engaged with internal and external stakeholders to make sure that we build a forecast that reflects current program, policies, and development plans which impact the grid
• SCE’s forecasting team uses different data sources for forecasting the future Distributed Energy Resource (DER) load such as:
▪ Customer Data such as historical customer usage and DER adoption such as electric vehicles (EV)
o Demographic and Socio-Economic Data
o Customer program and survey participation results
o Existing project development impact
o Short and long-term customer plans on DER adoption such EV charging sites
When Should I Contact SCE Regarding Power Needs?
10 Plan Ahead – Providing Energy
Capacity
Did You Know? A new 12 kV circuit
which provides about 10MW of
power (roughly 12,000 amps @480 V)
can take between 2 to 3 years to
construct.
Did you Know? A new customer-
owned substation can take between 3
to 5 years to construct.
The more project information a
customer can provide and the earlier
they can reach out to SCE concerning
the energy requirements for a new
building project (or for upgrading an
existing building) the better.
• The Short Answer: As Soon As Possible. For
example, when you contact the city to initiate
business permits, reach out to SCE as well to
discuss your plans
• SCE will always provide the power our customers
require to operate their business but upgrades
to our grid may be required. Partnering with
SCE early will help ensure that the level of power
required is delivered in both a timely – and safe –
manner
• Customers should contact SCE as early as
possible, preferably 2 years, especially for large
power requests
• Contact the appropriate planning department to
discuss and review the scope of your project,
including plans for phasing in power
Countdown to 2045
11 • Builds on Pathway 2045 analysis (released in 2019) to account for recent state policies, climate impacts, reliability modeling, and market/technology advancements
• Updated analysis indicates deeper electrification by 2045 (90+% of vehicles and space/water heating in buildings) drives greater load and new system peaks
• As a result, the generation mix in 2045 more than doubles; solar, wind, and storage make up the majority of capacity; retained gas generation and emerging technologies (e.g., offshore wind, clean firm baseload) serve important roles to ensure system reliability • New transmission and distribution needed at unprecedented scale and speed (4-10x historical rates), requiring policy changes and increased operational efficiencies to plan, build, and operate; technology investment to optimize DERs at scale
• Clean power and electrification approach remains the most feasible and cost-effective way to meet state goals, despite a significant level of investments (~$370B statewide); the average SCE household can expect to save ~40% on total energy costs

Reliability Overview
13 14
What is Reliability?
• In simplest terms:
• Having dependable electricity when you need it
• Potential interruptions to dependable service
include the following:
• Maintenance outages (aka planned outages)
• Repair outages (aka unplanned outages)
• Sustained Outage = An outage lasting > 5
minutes
• Momentary Outage = An outage lasting ≤ 5
minutes
• Public Safety Power Shutoff (PSPS)
• Major Event Day (MED)
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). MEDs are sometimes excluded in reporting; in those reports, the exclusions will be noted.
Public Safety Power Shutoff (PSPS) : An operational protocol that SCE implements under extreme weather conditions 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. 15 How Do We Measure Reliability?
