What mid-pack Holston Electric Coop, Inc filings show

Holston Electric Coop, Inc is a member-owned electric cooperative operating in Tennessee under EIA identifier 8764. It reports service to approximately 32,167 customer accounts and generated about $0.08 billion in annual electric revenue, with a service footprint spanning 20 ZIP codes. Cooperative ownership means the utility is run for the benefit of the ratepayer-members who elect its board, rather than for shareholder returns, which can shift how rate and investment decisions get made.

In 2023, the average Holston Electric Coop, Inc customer experienced 235.4 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). That sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities. The SAIFI figure, which tracks average outage events per customer, came in at 3.07 for the same period, meaning customers statistically saw about 3 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 171.6 minutes, the gap between that figure and the headline 235.4 reveals how much weather, not day-to-day infrastructure, drove outages.

Holston Electric Coop, Inc has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. SAIDI has increased from 200.3 to 235.4 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
