PUD No 1 of Jefferson County is a municipally-owned utility operating in Washington under EIA identifier 59013. It reports service to approximately 20,873 customer accounts and generated about $0.04 billion in annual electric revenue. 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 PUD No 1 of Jefferson County customer experienced 316.4 minutes of power interruptions — a metric called SAIDI (System Average Interruption Duration Index). That is substantially above the 120–180 minute national benchmark, indicating either storm-prone geography, aging infrastructure, or extended restoration windows. SAIFI — the average number of outage events per customer — was 1.74 for the same period, so customers statistically faced roughly 2 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 316.4 minutes — the gap between that figure and the headline 316.4 reveals how much weather, not day-to-day infrastructure, drove outages.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for PUD No 1 of Jefferson County, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has improved from 397.6 to 316.4 minutes over that window — a meaningful direction for prospective customers and regulators watching capital investment outcomes. All figures on this page come directly from EIA Form 861, the federal annual electric power industry survey — you can cross-reference them with your own utility bill or use them when comparing providers before relocating.
