Three Rivers Electric Coop is a member-owned electric cooperative operating in Missouri under EIA identifier 16751. It reports service to approximately 24,253 customer accounts and generated about $0.05 billion in annual electric revenue, with a service footprint spanning 48 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 Three Rivers Electric Coop customer experienced 173.8 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. That sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities. Over the same period, SAIFI (outage events per customer) was 1.11, putting the typical customer at roughly 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 139.7 minutes; the difference from the headline 173.8 shows how much of the outage total came from weather rather than everyday grid issues.
Three Rivers Electric Coop 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 82.6 to 173.8 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
