What long-outage Entergy Texas Inc. filings show
Entergy Texas Inc. is an investor-owned utility operating in Texas under EIA identifier 55937. It reports service to approximately 506,334 customer accounts and generated about $1.94 billion in annual electric revenue, with a service footprint spanning 242 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 Entergy Texas Inc. customer experienced 546.1 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). That is substantially above the 120–180 minute national benchmark, indicating either storm-prone geography, aging infrastructure, or extended restoration windows. Over the same period, SAIFI (outage events per customer) was 2.38, putting the typical customer at roughly 2 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 309.0 minutes, the gap between that figure and the headline 546.1 reveals how much weather, not day-to-day infrastructure, drove outages.
With 4 consecutive years of EIA data (2020–2023), Entergy Texas Inc.'s reliability record can be judged on trend rather than one isolated year. SAIDI has improved from 2538.8 to 546.1 minutes over that window, a meaningful direction for prospective customers and regulators watching capital investment outcomes.
Based on this utility's own EIA Form 861 reliability record -- baseline (major-event- excluded) outage duration, total outage duration, and outage frequency -- each benchmarked against every reporting utility nationwide. Not a measure of electricity rates or customer service, which this portal does not track.

Price vs. reliability
Where Entergy Texas Inc. sits on price vs. reliability
Among the 781 U.S. utilities large enough to report both revenue per customer and a recent outage record, Entergy Texas Inc. charges more per customer than 92% of them, and is more reliable (lower SAIDI) than 18% of them, placing it in the quadrant where it pays more but is LESS reliable, a premium price without a reliability payoff. Revenue per customer and outage minutes are independent figures: paying more does not guarantee fewer outages.
Revenue per customer: $3,835/year · Latest SAIDI: 546.1 minutes/year.
