San Diego Gas & Electric Co

What This Utility Data Tells You

San Diego Gas & Electric Co is an investor-owned utility operating in California under EIA identifier 16609. It reports service to approximately 512,633 customer accounts and generated about $1.86 billion in annual electric revenue, with a service footprint spanning 210 ZIP codes. Because it is investor-owned, the state public utility commission oversees its rate cases and reliability performance rather than a local board.

In 2023, the average San Diego Gas & Electric Co customer experienced 70.6 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). That is comfortably under the 120–180 minute national benchmark range, a sign of solid grid resilience and quick outage response. SAIFI, the average number of outage events per customer, was 0.59 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 70.6 minutes, the gap between that figure and the headline 70.6 reveals how much weather, not day-to-day infrastructure, drove outages.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for San Diego Gas & Electric Co, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has improved from 200.4 to 70.6 minutes over that window, a meaningful direction for prospective customers and regulators watching capital investment outcomes.
