Missoula Electric Coop, Inc is a member-owned electric cooperative operating in Montana under EIA identifier 12692. It reports service to approximately 16,258 customer accounts and generated about $0.03 billion in annual electric revenue, with a service footprint spanning 36 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 Missoula Electric Coop, Inc customer experienced 165.2 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). That falls inside the typical 120–180 minute national benchmark, in line with what most U.S. distribution utilities report. Over the same period, SAIFI (outage events per customer) was 1.19, putting the typical customer at roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 165.2 minutes, the gap between that figure and the headline 165.2 reveals how much weather, not day-to-day infrastructure, drove outages.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for Missoula Electric Coop, Inc, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI dropped from 362.4 to 165.2 minutes across that span, a direction regulators and prospective customers tend to watch closely.
