Trico Electric Cooperative Inc is a member-owned electric cooperative operating in Arizona under EIA identifier 19189. It reports service to approximately 52,926 customer accounts and generated about $0.12 billion in annual electric revenue, with a service footprint spanning 34 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 Trico Electric Cooperative Inc customer experienced 237.9 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). Excluding major weather events from that total, that is comfortably under the 120–180 minute national benchmark range, a sign of solid grid resilience and quick outage response. The SAIFI figure, which tracks average outage events per customer, came in at 1.17 for the same period, meaning customers statistically saw about 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 81.9 minutes; the difference from the headline 237.9 shows how much of the outage total came from weather rather than everyday grid issues.
Trico Electric Cooperative Inc 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 124.8 to 237.9 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
