Fergus Electric Coop, Inc is a member-owned electric cooperative operating in Montana under EIA identifier 21513. It reports service to approximately 6,911 customer accounts and generated about $0.03 billion in annual electric revenue, with a service footprint spanning 49 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 Fergus Electric Coop, Inc customer experienced 390.5 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). That is substantially above the 120–180 minute national benchmark, indicating either storm-prone geography, aging infrastructure, or extended restoration windows. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 347.2 minutes; the difference from the headline 390.5 shows how much of the outage total came from weather rather than everyday grid issues.
Fergus Electric Coop, 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 climbed from 348.0 to 390.5 minutes over that window, a shift that can point to worsening weather exposure or delayed grid modernization.
