What long-outage Conway Corporation filings show
Conway Corporation is a municipally-owned utility operating in Arkansas under EIA identifier 4280. It reports service to approximately 33,522 customer accounts and generated about $0.07 billion in annual electric revenue, with a service footprint spanning 5 ZIP codes. As a municipal utility, it is typically governed by a local board or city council and is exempt from federal income tax.
In 2023, the average Conway Corporation customer experienced 366.0 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). Excluding major weather events from that total, that places this utility well below the 120–180 minute national benchmark, signaling strong grid hardening and fast restoration practices. The SAIFI figure, which tracks average outage events per customer, came in at 0.86 for the same period, meaning customers statistically saw about 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 63.1 minutes; the difference from the headline 366.0 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 Conway Corporation, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. Over that span, SAIDI rose from 68.3 to 366.0 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
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.
