Reliability Overview 6 www.sce.com/outage-center/outage-information/reliability-reports 7 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 •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 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. 8 How Do We Measure Reliability? Total minutes every SCE customer was without power due to sustained outages Total number of customers SAIDI System Average Interruption Duration Index Total number of sustained customer outages experienced by SCE customers (CI) Total number of customers SAIFI System Average Interruption Frequency Index Total number of momentary customer outages experienced by SCE customers (CI) Total number of customers MAIFI Momentary Average Interruption Frequency Index What’s the average amount of time my power service will be unexpectedly interrupted? What’s the average number of times my power service will be unexpectedly interrupted? What’s the average number of times my power service will be momentarily (< 5 minutes) interrupted? Equipment Failure In-service failure of transformer, switch, or conductors Vegetation/Animal A tree branch, rodent, or bird causing a short circuit between conductors Other The circuit was patrolled but no cause found Operations SCE performed urgent maintenance without the standard 3-day notice 3rd Party Outage caused by a balloon, car hit pole or dig-in PSPS Public Safety Power Shutoff sce.com/psps SAIDI & SAIFI Cause Definitions 9 CircuitList1Overview of Moorpark There are 10 circuits that serve Moorpark 1 Circuit Type Customers Circuit Type Customers Circuit Type Customers Circuit Type Customers ANTON(16KV)302 --- BRENNAN(16KV)2,493 --- COLLINS(16KV)1,792 --- ENCHANTED(16KV)382 --- EVERETT(16KV)2,073 --- GABBERT(16KV)2,357 --- JANSS(16KV)3,212 --- MORGANSTEIN(16KV)2,017 --- STRATHERN(16KV)2,678 --- ZONE(16KV)946 --- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- Grand Total 18,252 Note: The number of customers listed represents the total number of customers on each circuit (not the local jurisdiction). 10 CircuitMap 11 BarChart 12 * NO EXCLUSIONS **Data is as of 03/12/2023, data can be slightly different due to outage data validation process Historical Reliability of Circuits Serving Moorpark 0.8 0.5 1.0 0.5 1.4 1.4 1.6 1.4 MAIFI(the average frequency of momentary interruptions) SCE GRID Moorpark 863.3 825.1 1,465.0 282.8 178.0 201.3 179.8 131.1 2019 2020 2021 2022 SAIDI(the average minutes of sustained interruptions) 1.1 1.9 2.1 1.7 1.0 1.1 1.1 1.1 SAIFI(the average frequency of sustained interruptions) www.sce.com/outage-center/outage-information/reliability-reports SAIDIChart 13 1.6% 2.5% 2.5% 3.1% 12.4% 19.3% 58.6% Weather /Fire /Earthquake 3rd Party Vegetation /Animal Operation Other Equipment Failure PSPS 2022 SAIDI Outage Causes for Moorpark SAIDI = the cumulative amount of time the average customer is interrupted by “sustained” outages each year.
