PUD No 1 of Clark County - (WA) is a municipally-owned utility operating in Washington under EIA identifier 3660. It reports service to approximately 235,481 customer accounts and generated about $0.39 billion in annual electric revenue, with a service footprint spanning 27 ZIP codes. Being municipally owned, the utility answers to a local board or city council rather than a state commission, and carries a federal income tax exemption.
In 2023, the average PUD No 1 of Clark County - (WA) customer experienced 88.4 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). That keeps this utility below the typical 120–180 minute national benchmark, consistent with a well-hardened distribution system and fast restoration crews. Over the same period, SAIFI (outage events per customer) was 0.81, putting the typical customer at roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 45.0 minutes, the gap between that figure and the headline 88.4 reveals how much weather, not day-to-day infrastructure, drove outages.
With 4 consecutive years of EIA data (2020–2023), PUD No 1 of Clark County - (WA)'s reliability record can be judged on trend rather than one isolated year. SAIDI dropped from 120.8 to 88.4 minutes across that span, a direction regulators and prospective customers tend to watch closely.
