What This Utility Data Tells You

Meriwether Lewis Electric Coop is a member-owned electric cooperative operating in Tennessee under EIA identifier 12330. It reports service to approximately 36,203 customer accounts and generated about $0.11 billion in annual electric revenue, with a service footprint spanning 37 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 Meriwether Lewis Electric Coop customer experienced 554.9 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. Excluding major weather events from that total, 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 2.21 for the same period, meaning customers statistically saw about 2 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 170.2 minutes, the gap between that figure and the headline 554.9 reveals how much weather, not day-to-day infrastructure, drove outages.

With 4 consecutive years of EIA data (2020–2023), Meriwether Lewis Electric Coop's reliability record can be judged on trend rather than one isolated year. SAIDI dropped from 910.8 to 554.9 minutes across that span, a direction regulators and prospective customers tend to watch closely.
