AEP Texas North Company

What This Utility Data Tells You

AEP Texas North Company is a investor-owned utility operating in Texas under EIA identifier 20404. Customer count is not reported in the current EIA filing. As an investor-owned utility, it operates under state public utility commission oversight that reviews rate cases and reliability performance.

In 2023, the average AEP Texas North Company customer experienced 144.9 minutes of power interruptions — a metric called SAIDI (System Average Interruption Duration Index). That sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities. SAIFI — the average number of outage events per customer — was 1.24 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 105.9 minutes — the gap between that figure and the headline 144.9 reveals how much weather, not day-to-day infrastructure, drove outages.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for AEP Texas North Company, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has improved from 280.1 to 144.9 minutes over that window — a meaningful direction for prospective customers and regulators watching capital investment outcomes. All figures on this page come directly from EIA Form 861, the federal annual electric power industry survey — you can cross-reference them with your own utility bill or use them when comparing providers before relocating.
