In 2023, the average Evergy Kansas South, Inc customer experienced 113.7 minutes of power interruptions — a metric called SAIDI (System Average Interruption Duration Index). That sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities.

Excluding major event days (hurricanes, ice storms), SAIDI drops to 84.4 minutes — the gap between that figure and the headline 113.7 reveals how much weather, not day-to-day infrastructure, drove outages.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Evergy Kansas South, Inc, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has increased from 86.2 to 113.7 minutes, which may reflect either worsening weather exposure or delayed grid modernization. All figures on this page come directly from EIA Form 861, the federal annual electric power industry survey, with service territory ZIPs sourced from OpenEI — you can cross-reference them with your own utility bill or use them when comparing providers before relocating.
