Coast Electric Power Assn - (MS)

What This Utility Data Tells You

Coast Electric Power Assn - (MS) is a member-owned electric cooperative operating in Mississippi under EIA identifier 3841. It reports service to approximately 88,942 customer accounts and generated about $0.23 billion in annual electric revenue, with a service footprint spanning 27 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 Coast Electric Power Assn - (MS) customer experienced 107.6 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. That falls inside the typical 120–180 minute national benchmark, in line with what most U.S. distribution utilities report. Over the same period, SAIFI (outage events per customer) was 1.51, putting the typical customer at roughly 2 distinct interruptions that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 100.6 minutes, and the spread against the headline 107.6 indicates how much weather, versus routine infrastructure, drove the outage total.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Coast Electric Power Assn - (MS), which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI dropped from 4385.1 to 107.6 minutes across that span, a direction regulators and prospective customers tend to watch closely. Note: this figure is unusually low compared to typical U.S. utility performance and may reflect an incomplete EIA filing for this year rather than a genuine reliability improvement -- treat with caution and cross-check against Coast Electric Power Assn - (MS)'s other reported years.
