What mid-pack Inland Power & Light Company filings show
Inland Power & Light Company is a member-owned electric cooperative operating in Washington under EIA identifier 8699. It reports service to approximately 44,400 customer accounts and generated about $0.09 billion in annual electric revenue, with a service footprint spanning 98 ZIP codes. As a cooperative, its governance is accountable to its ratepayer-members rather than shareholders, which often shapes rate-setting and reinvestment priorities.
In 2023, the average Inland Power & Light Company customer experienced 219.0 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). That lands within the usual 120–180 minute national benchmark band, roughly on par with typical U.S. distribution-utility performance. Over the same period, SAIFI (outage events per customer) was 1.20, putting the typical customer at roughly 1 distinct interruption that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 201.0 minutes, and the spread against the headline 219.0 indicates how much weather, versus routine infrastructure, drove the outage total.
Inland Power & 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. SAIDI has improved from 797.0 to 219.0 minutes over that window, a meaningful direction for prospective customers and regulators watching capital investment outcomes.
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.

Revenue per customer and outage minutes are independent figures: paying more does not guarantee fewer outages.
