It reports service to approximately 240,818 customer accounts and generated about $0.47 billion in annual electric revenue, with a service footprint spanning 91 ZIP codes.

In 2023, the average Sumter Electric Coop, Inc customer experienced 71.4 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). That places this utility well below the 120–180 minute national benchmark, signaling strong grid hardening and fast restoration practices. The SAIFI figure, which tracks average outage events per customer, came in at 1.03 for the same period, meaning customers statistically saw about 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 68.2 minutes, the gap between that figure and the headline 71.4 reveals how much weather, not day-to-day infrastructure, drove outages.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Sumter Electric Coop, Inc, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has improved from 78.8 to 71.4 minutes over that window, a meaningful direction for prospective customers and regulators watching capital investment outcomes.
