South Central Electric Assn

What This Utility Data Tells You

South Central Electric Assn is a member-owned electric cooperative operating in Minnesota under EIA identifier 17550. It reports service to approximately 5,941 customer accounts and generated about $0.03 billion in annual electric revenue, with a service footprint spanning 36 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 South Central Electric Assn customer experienced 102.1 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). Excluding major weather events from that total, that keeps this utility below the typical 120–180 minute national benchmark, consistent with a well-hardened distribution system and fast restoration crews. The SAIFI figure, which tracks average outage events per customer, came in at 1.07 for the same period, meaning customers statistically saw about 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 51.0 minutes, the gap between that figure and the headline 102.1 reveals how much weather, not day-to-day infrastructure, drove outages.

With 4 consecutive years of EIA data (2020–2023), South Central Electric Assn's reliability record can be judged on trend rather than one isolated year. SAIDI has improved from 233.8 to 102.1 minutes over that window, a meaningful direction for prospective customers and regulators watching capital investment outcomes.
