What This Utility Data Tells You

Duke Energy Kentucky is an investor-owned utility operating in Kentucky under EIA identifier 19446. It reports service to approximately 151,127 customer accounts and generated about $0.41 billion in annual electric revenue, with a service footprint spanning 33 ZIP codes. Because it is investor-owned, the state public utility commission oversees its rate cases and reliability performance rather than a local board.

In 2023, the average Duke Energy Kentucky customer experienced 138.2 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). 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 0.74 for the same period, meaning customers statistically saw about 1 distinct interruption that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 72.1 minutes, and the spread against the headline 138.2 indicates how much weather, versus routine infrastructure, drove the outage total.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Duke Energy Kentucky, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has improved from 146.8 to 138.2 minutes over that window, a meaningful direction for prospective customers and regulators watching capital investment outcomes.
