Mille Lacs Energy Cooperative

What This Utility Data Tells You

Mille Lacs Energy Cooperative is a member-owned electric cooperative operating in Minnesota under EIA identifier 12546. It reports service to approximately 15,912 customer accounts and generated about $0.03 billion in annual electric revenue, with a service footprint spanning 15 ZIP codes. Being member-owned, this cooperative answers to its ratepayers rather than outside shareholders, a structure that tends to influence how rate cases and capital spending get decided.

In 2023, the average Mille Lacs Energy Cooperative customer experienced 153.6 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. That lands within the usual 120–180 minute national benchmark band, roughly on par with typical U.S. distribution-utility performance. Over the same period, SAIFI (outage events per customer) was 1.18, putting the typical customer at roughly 1 distinct interruption that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 153.6 minutes, and the spread against the headline 153.6 indicates how much weather, versus routine infrastructure, drove the outage total.

With 4 consecutive years of EIA data (2020–2023), Mille Lacs Energy Cooperative's reliability record can be judged on trend rather than one isolated year. SAIDI dropped from 715.2 to 153.6 minutes across that span, a direction regulators and prospective customers tend to watch closely.
