Los Angeles Department of Water & Power is a municipally-owned utility operating in California under EIA identifier 11208. It reports service to approximately 1,500,208 customer accounts and generated about $4.61 billion in annual electric revenue, with a service footprint spanning 260 ZIP codes. As a municipal utility, it is typically governed by a local board or city council and is exempt from federal income tax.
In 2023, the average Los Angeles Department of Water & Power customer experienced 198.8 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). That sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities. Over the same period, SAIFI (outage events per customer) was 0.76, putting the typical customer at roughly 1 distinct interruption that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 141.2 minutes, and the spread against the headline 198.8 indicates how much weather, versus routine infrastructure, drove the outage total.
With 4 consecutive years of EIA data (2020–2023), Los Angeles Department of Water & Power's reliability record can be judged on trend rather than one isolated year. SAIDI has increased from 139.6 to 198.8 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
