Lynches River Elec Coop, Inc is a member-owned electric cooperative operating in South Carolina under EIA identifier 11355. It reports service to approximately 22,179 customer accounts and generated about $0.06 billion in annual electric revenue, with a service footprint spanning 22 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 Lynches River Elec Coop, Inc customer experienced 332.9 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. Excluding major weather events from that total, that falls inside the typical 120–180 minute national benchmark, in line with what most U.S. distribution utilities report. SAIFI, the average number of outage events per customer, was 2.60 for the same period, so customers statistically faced roughly 3 distinct interruptions that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 149.8 minutes, and the spread against the headline 332.9 indicates how much weather, versus routine infrastructure, drove the outage total.
With 4 consecutive years of EIA data (2020–2023), Lynches River Elec Coop, Inc's reliability record can be judged on trend rather than one isolated year. SAIDI has improved from 360.0 to 332.9 minutes over that window, a meaningful direction for prospective customers and regulators watching capital investment outcomes.
