Alger-Delta Coop Electric Assn

What This Utility Data Tells You

Alger-Delta Coop Electric Assn is a member-owned electric cooperative operating in Michigan under EIA identifier 305. It reports service to approximately 10,319 customer accounts and generated about $0.02 billion in annual electric revenue, with a service footprint spanning 49 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 Alger-Delta Coop Electric Assn customer experienced 189.1 minutes of power interruptions, a measure known as SAIDI, or 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 1.04, putting the typical customer at roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 110.9 minutes, the gap between that figure and the headline 189.1 reveals how much weather, not day-to-day infrastructure, drove outages.

With 4 consecutive years of EIA data (2020–2023), Alger-Delta Coop Electric Assn's reliability record can be judged on trend rather than one isolated year. Over that span, SAIDI rose from 166.2 to 189.1 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
