Fairfield Electric Coop, Inc is a member-owned electric cooperative operating in South Carolina under EIA identifier 5929. It reports service to approximately 33,097 customer accounts and generated about $0.08 billion in annual electric revenue, with a service footprint spanning 39 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 Fairfield Electric Coop, Inc customer experienced 166.6 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. That lands within the usual 120–180 minute national benchmark band, roughly on par with typical U.S. distribution-utility performance. Over the same period, SAIFI (outage events per customer) was 2.31, putting the typical customer at roughly 2 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 142.6 minutes; the difference from the headline 166.6 shows how much of the outage total came from weather rather than everyday grid issues.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for Fairfield Electric Coop, Inc, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has increased from 158.6 to 166.6 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
