How We Measure Electric Reliability

Providing you with safe and reliable power is our top priority. We constantly track and monitor electricity (planned & unplanned) outages across our service area, and we measure our “Electric Reliability” from this data.

The two metrics we rely on are the following: the System Average Interruption Duration Index (SAIDI) and the System Average Interruption Frequency Index (SAIFI). Both are common metrics in the electric utility industry. 

  • SAIDI measures the amount of time the average SDG&E customer experienced a power outage or interruption for more than five minutes (called a “sustained outage”) in a given year. Our five-year SAIDI average is approximate 60 minutes per customer.
  • SAIFI is the number of times the average SDG&E customer experienced a sustained outage in a given year.
