What This Utility Data Tells You
Evergy Metro is an investor-owned utility operating in Kansas under EIA identifier 10000. It reports service to approximately 305,816 customer accounts and generated about $0.90 billion in annual electric revenue, with a service footprint spanning 238 ZIP codes. As an investor-owned utility, it operates under state public utility commission oversight that reviews rate cases and reliability performance.
In 2023, the average Evergy Metro customer experienced 543.9 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). Excluding major weather events from that total, that places this utility well below the 120–180 minute national benchmark, signaling strong grid hardening and fast restoration practices. SAIFI, the average number of outage events per customer, was 1.38 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 78.1 minutes, the gap between that figure and the headline 543.9 reveals how much weather, not day-to-day infrastructure, drove outages.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for Evergy Metro, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has increased from 73.8 to 543.9 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
