What This Utility Data Tells You

Entergy Arkansas LLC is a investor-owned utility operating in Arkansas under EIA identifier 814. It reports service to approximately 729,550 customer accounts and generated about $2.24 billion in annual electric revenue, with a service footprint spanning 500 ZIP codes. As an investor-owned utility, it operates under state public utility commission oversight that reviews rate cases and reliability performance.

In 2023, the average Entergy Arkansas LLC customer experienced 1211.8 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. SAIFI — the average number of outage events per customer — was 2.05 for the same period, so customers statistically faced roughly 2 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 284.7 minutes — the gap between that figure and the headline 1211.8 reveals how much weather, not day-to-day infrastructure, drove outages.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Entergy Arkansas LLC, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has increased from 1190.5 to 1211.8 minutes, which may reflect either worsening weather exposure or delayed grid modernization. All figures on this page come directly from EIA Form 861, the federal annual electric power industry survey, with service territory ZIPs sourced from OpenEI — you can cross-reference them with your own utility bill or use them when comparing providers before relocating.
