Powell Valley Electric Coop is a member-owned electric cooperative operating in Tennessee under EIA identifier 15293. It reports service to approximately 26,135 customer accounts and generated about $0.05 billion in annual electric revenue, with a service footprint spanning 31 ZIP codes. As a cooperative, its governance is accountable to its ratepayer-members rather than shareholders, which often shapes rate-setting and reinvestment priorities.
In 2023, the average Powell Valley Electric Coop customer experienced 390.2 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). That runs well past the 120–180 minute national benchmark, which can reflect storm-exposed terrain, an aging grid, or slower restoration times. The SAIFI figure, which tracks average outage events per customer, came in at 5.21 for the same period, meaning customers statistically saw about 5 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 316.7 minutes, the gap between that figure and the headline 390.2 reveals how much weather, not day-to-day infrastructure, drove outages.
Powell Valley Electric Coop has 3 years of continuous EIA reporting on file (2021–2023), enough to read a real trend rather than a single-year snapshot. SAIDI has increased from 229.2 to 390.2 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
