San Angelo, Texas — AEP Texas has restored power to nearly all customers in Tom Green County after a substation equipment failure left approximately 7,800 residents without electricity on Tuesday. By early Wednesday, the utility's outage map showed fewer than five customers still affected, according to local reports.
Outage Details
The disruption originated at a south San Angelo substation, where a breaker failure caused a widespread blackout. Initially, crews suspected a line issue, but further investigation pinpointed the substation equipment as the culprit. The outage affected parts of San Angelo and Tom Green County, with some areas experiencing a separate overnight interruption that impacted hundreds of customers before service was gradually restored.
Broader Context
The incident comes at a critical time for American Electric Power (AEP), the parent company based in Columbus, Ohio. AEP is under heightened investor scrutiny as Texas power demand surges, driven by data centers and large-scale industrial customers. The company recently outlined a $78 billion five-year capital plan, up from $72 billion, to expand transmission and distribution infrastructure. Nearly 90% of AEP's expected 63 gigawatts of new contracted load by 2030 is tied to data centers and hyperscalers, with about 41 gigawatts concentrated in Texas.
Financial and Market Implications
AEP's first-quarter operating earnings of $1.64 per share and revenue of $6.02 billion both exceeded analyst expectations. The company has guided for 2026 GAAP earnings between $6.12 and $6.42 per share. Wall Street remains largely bullish, with 22 brokerages covering the stock and a consensus rating of "Moderate Buy." Twelve analysts recommend buying, nine hold, and one rates it a strong buy, with a mean 12-month price target of approximately $141.57.
AEP shares traded at $128.92 early Wednesday, up about 1% from the prior close. The company's CEO, Bill Fehrman, emphasized in the first-quarter report that AEP is maintaining "an intense focus on affordability" while delivering "reliability and long-term value" for customers and stakeholders.
Regulatory and Operational Landscape
AEP Texas is one of several investor-owned transmission and distribution utilities in Texas, alongside CenterPoint Energy, Oncor, and TNMP, that manage poles, wires, and substations but do not sell power directly to consumers. The Public Utility Commission of Texas oversees these entities. While the San Angelo outage was relatively small in scale, it highlights the operational challenges facing the grid amid rapid demand growth.
Repair costs and a timeline for full substation fixes have not been disclosed. AEP Texas advises customers to monitor its outage tools for real-time updates and to report any issues. The utility serves 5.6 million customers across 11 states, operating 40,000 miles of transmission lines and over 252,000 miles of distribution lines.
