Gibson Electric Members Corp

What This Utility Data Tells You

Gibson Electric Members Corp is a member-owned electric cooperative operating in Tennessee under EIA identifier 7174. It reports service to approximately 35,622 customer accounts and generated about $0.09 billion in annual electric revenue, with a service footprint spanning 41 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 2021, the average Gibson Electric Members Corp customer experienced 958.9 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. Excluding major weather events from that total, that lands within the usual 120–180 minute national benchmark band, roughly on par with typical U.S. distribution-utility performance. SAIFI, the average number of outage events per customer, was 3.56 for the same period, so customers statistically faced roughly 4 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 132.9 minutes; the difference from the headline 958.9 shows how much of the outage total came from weather rather than everyday grid issues.

The EIA dataset includes 2 years of continuous reporting (2020–2021) for Gibson Electric Members Corp, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has increased from 245.8 to 958.9 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
