AEP Texas North Company

What This Utility Data Tells You

AEP Texas North Company is an investor-owned utility operating in Texas under EIA identifier 20404. Customer count is not reported in the current EIA filing. 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 AEP Texas North Company customer experienced 144.9 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). That lands within the usual 120–180 minute national benchmark band, roughly on par with typical U.S. distribution-utility performance. 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. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 105.9 minutes, and the spread against the headline 144.9 indicates how much weather, versus routine infrastructure, drove the outage total.

With 4 consecutive years of EIA data (2020–2023), AEP Texas North Company's reliability record can be judged on trend rather than one isolated year. 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.
