What This Utility Data Tells You

Kentucky Utilities Co is an investor-owned utility operating in Kentucky under EIA identifier 10171. It reports service to approximately 542,047 customer accounts and generated about $1.72 billion in annual electric revenue, with a service footprint spanning 376 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 Kentucky Utilities Co customer experienced 905.4 minutes of power interruptions, the industry-standard SAIDI metric (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. The SAIFI figure, which tracks average outage events per customer, came in at 1.34 for the same period, meaning customers statistically saw about 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 74.6 minutes, the gap between that figure and the headline 905.4 reveals how much weather, not day-to-day infrastructure, drove outages.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Kentucky Utilities Co, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI climbed from 84.4 to 905.4 minutes over that window, a shift that can point to worsening weather exposure or delayed grid modernization.
