1 Circuit Reliability Review Beverly Hills January 2018

2 Building a Smarter Grid for Southern California Southern California Edison is developing an electric grid to support California s transition to a clean and sustainable future that meets the needs and expectations of our customers. We are investing more than $13 billion in the power distribution grid over three years ( ). Our main investment goal is to increase power reliability through significant upgrades. The investments include: Upgrading cables, poles, switches and transformers Updating the grid so it can accommodate new technologies, such as smart inverters that will allow for the twoway flow of solar energy Adapting the power system to accommodate future California policy related to energy storage, electric transportation and renewable energy Providing enhanced automation and monitoring devices to allow us to better respond to changes on the grid Our investments in local communities will help ensure that customers receive safe, reliable, and affordable electricity now and in the future.

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