What This Utility Data Tells You
Aiken Electric Coop Inc is a member-owned electric cooperative operating in South Carolina under EIA identifier 162. It reports service to approximately 51,929 customer accounts and generated about $0.13 billion in annual electric revenue, with a service footprint spanning 50 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 Aiken Electric Coop Inc customer experienced 152.7 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. That sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 113.1 minutes; the difference from the headline 152.7 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 Aiken Electric Coop Inc, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. Over that window, SAIDI moved from 203.7 down to 152.7 minutes, a trend worth noting for anyone weighing capital investment outcomes.
