The EIA dataset includes 4 years of continuous reporting (2020–2023) for Evergy Kansas Central, Inc, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has increased from 106.9 to 197.9 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.
