It reports service to approximately 395,731 customer accounts and generated about $1.06 billion in annual electric revenue, with a service footprint spanning 283 ZIP codes.

In 2023, the average Evergy Kansas Central, Inc customer experienced 197.9 minutes of power interruptions, a measure known as SAIDI, or 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. Over the same period, SAIFI (outage events per customer) was 1.26, putting the typical customer at roughly 1 distinct interruption that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 96.7 minutes, and the spread against the headline 197.9 indicates how much weather, versus routine infrastructure, drove the outage total.
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. Over that span, SAIDI rose from 106.9 to 197.9 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
