Entergy Arkansas LLC is an 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. Investor ownership puts this utility under the regulatory authority of the state public utility commission, which reviews its rate requests and reliability record.
In 2023, the average Entergy Arkansas LLC customer experienced 1211.8 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. Excluding major weather events from that total, that sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities. The SAIFI figure, which tracks average outage events per customer, came in at 2.05 for the same period, meaning customers statistically saw about 2 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 284.7 minutes; the difference from the headline 1211.8 shows how much of the outage total came from weather rather than everyday grid issues.
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 climbed from 1190.5 to 1211.8 minutes over that window, a shift that can point to worsening weather exposure or delayed grid modernization.
