What This Utility Data Tells You
Yakama Power is a member-owned electric cooperative operating in Washington under EIA identifier 56621. It reports service to approximately 2,298 customer accounts and generated about $0.01 billion in annual electric revenue. Being member-owned, this cooperative answers to its ratepayers rather than outside shareholders, a structure that tends to influence how rate cases and capital spending get decided.
In 2023, the average Yakama Power customer experienced 402.0 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. Excluding major weather events from that total, that sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities. SAIFI, the average number of outage events per customer, was 1.47 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 101.0 minutes; the difference from the headline 402.0 shows how much of the outage total came from weather rather than everyday grid issues.
Only a single year of reliability data is available, so multi-year trend analysis is not yet possible for Yakama Power.
