Tri-County Electric Coop, Inc (SC)

What This Utility Data Tells You

Tri-County Electric Coop, Inc (SC) is a member-owned electric cooperative operating in South Carolina under EIA identifier 14175. It reports service to approximately 18,377 customer accounts and generated about $0.05 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 Tri-County Electric Coop, Inc (SC) customer experienced 427.4 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. Over the same period, SAIFI (outage events per customer) was 3.75, putting the typical customer at roughly 4 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 196.9 minutes, the gap between that figure and the headline 427.4 reveals how much weather, not day-to-day infrastructure, drove outages.

Tri-County Electric Coop, Inc (SC) 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 244.8 to 427.4 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
