It reports service to approximately 34,809 customer accounts and generated about $0.08 billion in annual electric revenue, with a service footprint spanning 44 ZIP codes.

In 2023, the average PUD No 1 of Lewis County customer experienced 444.5 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). That exceeds the 120–180 minute national benchmark by a wide margin, a pattern often tied to severe weather exposure, older infrastructure, or longer repair windows. The SAIFI figure, which tracks average outage events per customer, came in at 3.04 for the same period, meaning customers statistically saw about 3 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 423.3 minutes; the difference from the headline 444.5 shows how much of the outage total came from weather rather than everyday grid issues.

PUD No 1 of Lewis County has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. SAIDI has increased from 433.4 to 444.5 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
