Southwest Arkansas E C C

What This Utility Data Tells You

Southwest Arkansas E C C is a member-owned electric cooperative operating in Arkansas under EIA identifier 17671. It reports service to approximately 27,705 customer accounts and generated about $0.07 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 Southwest Arkansas E C C customer experienced 452.5 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 1.99, putting the typical customer at roughly 2 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 251.7 minutes, the gap between that figure and the headline 452.5 reveals how much weather, not day-to-day infrastructure, drove outages.

With 4 consecutive years of EIA data (2020–2023), Southwest Arkansas E C C's reliability record can be judged on trend rather than one isolated year. SAIDI climbed from 305.4 to 452.5 minutes over that window, a shift that can point to worsening weather exposure or delayed grid modernization.
