Delta Electric Power Assn

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. 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 Delta Electric Power Assn customer experienced 1309.3 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). That runs well past the 120–180 minute national benchmark, which can reflect storm-exposed terrain, an aging grid, or slower restoration times. Over the same period, SAIFI (outage events per customer) was 17.38, putting the typical customer at roughly 17 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 1069.3 minutes; the difference from the headline 1309.3 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 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.
