1 Circuit Reliability Review Orange District 3 January

2 Providing Safe, Reliable, and Affordable Power is modernizing the power grid to meet the changing needs and expectations of our customers and to help California achieve its clean energy goals. We are investing more than $12 billion into our power grid between with the goal of increasing power reliability through significant upgrades. These investments include: Updating thousands of transmission and distribution poles Replacing hundreds of miles of underground cables Replacing hundreds of underground structures such as vaults and manholes Upgrading critical distribution equipment; capacitor banks, switches, and circuit breakers Building new distribution circuits to serve electrical demands in our communities Inspecting and replacing overhead conductor and equipment to improve public safety Our investments in local communities will help ensure that customers receive safe, reliable, and affordable electricity now and in the future. 2

3 Understanding Your Reliability Report As your electric utility, we want you to always have power when you need it. To get there, we constantly track and monitor electric outages across our service territory, and we measure our system reliability from this data. The two metrics we rely on are common in the electric utility industry: the System Average Interruption Duration Index (SAIDI) and the System Average Interruption Frequency Index (SAIFI). Both are described in more detail on the next page. Replacing and upgrading our infrastructure will help SCE maintain or improve SAIDI and SAIFI measurements. This report provides historical reliability data for the circuits that serve your jurisdiction and our proposed infrastructure upgrades for the current year.

4 Reliability Metrics MOMENTARY OUTAGES: OUTAGES LASTING 5 MINUTES OR LESS MAIFI: The number of times the average customer is interrupted by Momentary outages each year. SUSTAINED OUTAGES: OUTAGES LASTING LONGER THAN 5 MINUTES SAIFI: The number of times the average customer is interrupted by Sustained outages each year. SAIDI: The cumulative amount of time the average customer is interrupted by Sustained outages each year. 4
