Black River Electric Coop, Inc - (SC)

What This Utility Data Tells You

Black River Electric Coop, Inc - (SC) is a member-owned electric cooperative operating in South Carolina under EIA identifier 1763. It reports service to approximately 34,508 customer accounts and generated about $0.08 billion in annual electric revenue, with a service footprint spanning 40 ZIP codes. Being member-owned, this cooperative answers to its ratepayers rather than outside shareholders, a structure that tends to influence how rate cases and capital spending get decided.

In 2023, the average Black River Electric Coop, Inc - (SC) customer experienced 126.0 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). 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 1.18 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 115.0 minutes, the gap between that figure and the headline 126.0 reveals how much weather, not day-to-day infrastructure, drove outages.

Black River 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 climbed from 101.7 to 126.0 minutes over that window, a shift that can point to worsening weather exposure or delayed grid modernization.
