What long-outage Weakley County Mun Elec Sys filings show
Weakley County Mun Elec Sys is a municipally-owned utility operating in Tennessee under EIA identifier 20228. It reports service to approximately 20,751 customer accounts and generated about $0.05 billion in annual electric revenue, with a service footprint spanning 22 ZIP codes. Municipal ownership means a local board or city council typically oversees this utility, and it is exempt from federal income tax.
In 2023, the average Weakley County Mun Elec Sys customer experienced 354.4 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). Excluding major weather events from that total, that falls inside the typical 120–180 minute national benchmark, in line with what most U.S. distribution utilities report. The SAIFI figure, which tracks average outage events per customer, came in at 13.40 for the same period, meaning customers statistically saw about 13 distinct interruptions that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 176.4 minutes, and the spread against the headline 354.4 indicates how much weather, versus routine infrastructure, drove the outage total.
With 4 consecutive years of EIA data (2020–2023), Weakley County Mun Elec Sys's reliability record can be judged on trend rather than one isolated year. SAIDI has increased from 161.0 to 354.4 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
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.
