What This Utility Data Tells You
Fort Loudoun Electric Coop is a member-owned electric cooperative operating in Tennessee under EIA identifier 6608. It reports service to approximately 35,523 customer accounts and generated about $0.08 billion in annual electric revenue, with a service footprint spanning 17 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 Fort Loudoun Electric Coop customer experienced 721.6 minutes of power interruptions, the industry-standard SAIDI metric (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. The SAIFI figure, which tracks average outage events per customer, came in at 3.91 for the same period, meaning customers statistically saw about 4 distinct interruptions that year.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for Fort Loudoun Electric Coop, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI climbed from 464.4 to 721.6 minutes over that window, a shift that can point to worsening weather exposure or delayed grid modernization.
