Evergy Missouri West

What This Utility Data Tells You

Evergy Missouri West is an investor-owned utility operating in Missouri under EIA identifier 12698. It reports service to approximately 343,879 customer accounts and generated about $0.88 billion in annual electric revenue, with a service footprint spanning 191 ZIP codes. Because it is investor-owned, the state public utility commission oversees its rate cases and reliability performance rather than a local board.

In 2023, the average Evergy Missouri West customer experienced 220.2 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 1.57, putting the typical customer at roughly 2 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 119.1 minutes, the gap between that figure and the headline 220.2 reveals how much weather, not day-to-day infrastructure, drove outages.

With 4 consecutive years of EIA data (2020–2023), Evergy Missouri West's reliability record can be judged on trend rather than one isolated year. Over that window, SAIDI moved from 247.9 down to 220.2 minutes, a trend worth noting for anyone weighing capital investment outcomes.
