West Central Electric Coop Inc - (MO) is a member-owned electric cooperative operating in Missouri under EIA identifier 20363. It reports service to approximately 15,185 customer accounts and generated about $0.03 billion in annual electric revenue, with a service footprint spanning 45 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 West Central Electric Coop Inc - (MO) customer experienced 145.5 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). Excluding major weather events from that total, that is comfortably under the 120–180 minute national benchmark range, a sign of solid grid resilience and quick outage response. SAIFI, the average number of outage events per customer, was 1.10 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 60.7 minutes, the gap between that figure and the headline 145.5 reveals how much weather, not day-to-day infrastructure, drove outages.
With 4 consecutive years of EIA data (2020–2023), West Central Electric Coop Inc - (MO)'s reliability record can be judged on trend rather than one isolated year. Over that span, SAIDI rose from 113.9 to 145.5 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
