What This Utility Data Tells You

Delta Electric Power Assn is a member-owned electric cooperative operating in Mississippi under EIA identifier 22815. It reports service to approximately 28,902 customer accounts and generated about $0.07 billion in annual electric revenue, with a service footprint spanning 56 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 Delta Electric Power Assn customer experienced 1309.3 minutes of power interruptions — a metric called SAIDI (System Average Interruption Duration Index). That is substantially above the 120–180 minute national benchmark, indicating either storm-prone geography, aging infrastructure, or extended restoration windows. SAIFI — the average number of outage events per customer — was 17.38 for the same period, so customers statistically faced roughly 17 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 1069.3 minutes — the gap between that figure and the headline 1309.3 reveals how much weather, not day-to-day infrastructure, drove outages.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Delta Electric Power Assn, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has improved from 1597.9 to 1309.3 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, with service territory ZIPs sourced from OpenEI — you can cross-reference them with your own utility bill or use them when comparing providers before relocating.

A lower SAIDI indicates better reliability. The national average is roughly 120-180 minutes per year, so comparing Delta Electric Power Assn's SAIDI to that benchmark shows whether this utility is above or below average.

What is SAIDI without major event days?

SAIDI "without major event days" (SAIDI nMED) excludes outages caused by hurricanes, ice storms, and other catastrophic weather events. It better reflects day-to-day infrastructure reliability rather than vulnerability to extreme weather. Both standard SAIDI and SAIDI nMED are shown in the reliability trend table above.
