What mid-pack Horry Electric Coop Inc filings show
Horry Electric Coop Inc is a member-owned electric cooperative operating in South Carolina under EIA identifier 8786. It reports service to approximately 94,537 customer accounts and generated about $0.17 billion in annual electric revenue, with a service footprint spanning 23 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 Horry Electric Coop Inc customer experienced 156.0 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. That keeps this utility below the typical 120–180 minute national benchmark, consistent with a well-hardened distribution system and fast restoration crews. Over the same period, SAIFI (outage events per customer) was 1.54, putting the typical customer at roughly 2 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 99.4 minutes, the gap between that figure and the headline 156.0 reveals how much weather, not day-to-day infrastructure, drove outages.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for Horry 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 116.7 to 156.0 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
Based on this utility's own EIA Form 861 reliability record -- baseline (major-event- excluded) outage duration, total outage duration, and outage frequency -- each benchmarked against every reporting utility nationwide. Not a measure of electricity rates or customer service, which this portal does not track.
