What mid-pack Peninsula Light Company filings show
Peninsula Light Company is a member-owned electric cooperative operating in Washington under EIA identifier 14668. It reports service to approximately 35,429 customer accounts and generated about $0.06 billion in annual electric revenue, with a service footprint spanning 18 ZIP codes. Cooperative ownership means the utility is run for the benefit of the ratepayer-members who elect its board, rather than for shareholder returns, which can shift how rate and investment decisions get made.
In 2023, the average Peninsula Light Company customer experienced 179.5 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). That falls inside the typical 120–180 minute national benchmark, in line with what most U.S. distribution utilities report. SAIFI, the average number of outage events per customer, was 1.34 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 106.0 minutes, and the spread against the headline 179.5 indicates how much weather, versus routine infrastructure, drove the outage total.
Peninsula Light Company has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. Over that span, SAIDI rose from 77.0 to 179.5 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
Based on this utility's own EIA Form 861 reliability record -- baseline (major-event- excluded) outage duration, total outage duration, and outage frequency -- each benchmarked against every reporting utility nationwide. Not a measure of electricity rates or customer service, which this portal does not track.

Price vs. reliability
Where Peninsula Light Company sits on price vs. reliability
Among the 781 U.S. utilities large enough to report both revenue per customer and a recent outage record, Peninsula Light Company charges more per customer than 4% of them, and is more reliable (lower SAIDI) than 50% of them, placing it in the quadrant where it pays less while still being more reliable, the best-value quadrant. Revenue per customer and outage minutes are independent figures: paying more does not guarantee fewer outages.
Revenue per customer: $1,722/year · Latest SAIDI: 179.5 minutes/year.
