What This Utility Data Tells You

Louisville Gas & Electric Co is an investor-owned utility operating in Kentucky under EIA identifier 11249. It reports service to approximately 434,120 customer accounts and generated about $1.18 billion in annual electric revenue, with a service footprint spanning 97 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 Louisville Gas & Electric Co customer experienced 1163.3 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 1.47 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 68.9 minutes, the gap between that figure and the headline 1163.3 reveals how much weather, not day-to-day infrastructure, drove outages.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Louisville Gas & Electric Co, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. Over that span, SAIDI rose from 107.1 to 1163.3 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
