What mid-pack Evergy Kansas South, Inc filings show
Evergy Kansas South, Inc is an investor-owned utility operating in Kansas under EIA identifier 10005. It reports service to approximately 342,905 customer accounts and generated about $0.99 billion in annual electric revenue, with a service footprint spanning 160 ZIP codes. Investor ownership puts this utility under the regulatory authority of the state public utility commission, which reviews its rate requests and reliability record.
In 2023, the average Evergy Kansas South, Inc customer experienced 113.7 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). 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. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 84.4 minutes, and the spread against the headline 113.7 indicates how much weather, versus routine infrastructure, drove the outage total.
Evergy Kansas South, Inc has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. SAIDI climbed from 86.2 to 113.7 minutes over that window, a shift that can point to worsening weather exposure or delayed grid modernization.
Based on this utility's own EIA Form 861 reliability record -- baseline (major-event- excluded) outage duration, total outage duration, and outage frequency -- each benchmarked against every reporting utility nationwide. Not a measure of electricity rates or customer service, which this portal does not track.
