Tri-County Electric Coop, Inc (OK) is a member-owned electric cooperative operating in Oklahoma under EIA identifier 19160. It reports service to approximately 26,282 customer accounts and generated about $0.10 billion in annual electric revenue, with a service footprint spanning 37 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 Tri-County Electric Coop, Inc (OK) customer experienced 288.8 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). That sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities. The SAIFI figure, which tracks average outage events per customer, came in at 1.57 for the same period, meaning customers statistically saw about 2 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 235.1 minutes; the difference from the headline 288.8 shows how much of the outage total came from weather rather than everyday grid issues.
With 4 consecutive years of EIA data (2020–2023), Tri-County Electric Coop, Inc (OK)'s reliability record can be judged on trend rather than one isolated year. SAIDI climbed from 148.2 to 288.8 minutes over that window, a shift that can point to worsening weather exposure or delayed grid modernization.
