What short-outage Alcorn County Elec Power Assn filings show

Alcorn County Elec Power Assn is a member-owned electric cooperative operating in Mississippi under EIA identifier 276. It reports service to approximately 19,113 customer accounts and generated about $0.06 billion in annual electric revenue, with a service footprint spanning 10 ZIP codes. Being member-owned, this cooperative answers to its ratepayers rather than outside shareholders, a structure that tends to influence how rate cases and capital spending get decided.

In 2023, the average Alcorn County Elec Power Assn customer experienced 3.6 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. That is comfortably under the 120–180 minute national benchmark range, a sign of solid grid resilience and quick outage response. The SAIFI figure, which tracks average outage events per customer, came in at 1.58 for the same period, meaning customers statistically saw about 2 distinct interruptions that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 3.6 minutes, and the spread against the headline 3.6 indicates how much weather, versus routine infrastructure, drove the outage total.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Alcorn County Elec Power Assn, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has improved from 90.6 to 3.6 minutes over that window, a meaningful direction for prospective customers and regulators watching capital investment outcomes. Note: this figure is unusually low compared to typical U.S. utility performance and may reflect an incomplete EIA filing for this year rather than a genuine reliability improvement -- treat with caution and cross-check against Alcorn County Elec Power Assn's other reported years.
