Marlboro Electric Coop, Inc

What This Utility Data Tells You

Marlboro Electric Coop, Inc is a member-owned electric cooperative operating in South Carolina under EIA identifier 11693. Customer count is not reported in the current EIA filing. As a cooperative, its governance is accountable to its ratepayer-members rather than shareholders, which often shapes rate-setting and reinvestment priorities.

In 2022, the average Marlboro Electric Coop, Inc customer experienced 220.5 minutes of power interruptions — a metric called SAIDI (System Average Interruption Duration Index). That sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities. SAIFI — the average number of outage events per customer — was 1.10 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 44.2 minutes — the gap between that figure and the headline 220.5 reveals how much weather, not day-to-day infrastructure, drove outages.

The EIA dataset includes 3 years of continuous reporting (2020–2022) for Marlboro 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 956.0 to 220.5 minutes over that window — a meaningful direction for prospective customers and regulators watching capital investment outcomes. All figures on this page come directly from EIA Form 861, the federal annual electric power industry survey — you can cross-reference them with your own utility bill or use them when comparing providers before relocating.
