Central Electric Power Assn - (MS) is a member-owned electric cooperative operating in Mississippi under EIA identifier 2849. It reports service to approximately 38,637 customer accounts and generated about $0.10 billion in annual electric revenue, with a service footprint spanning 35 ZIP codes. Cooperative ownership means the utility is run for the benefit of the ratepayer-members who elect its board, rather than for shareholder returns, which can shift how rate and investment decisions get made.
In 2023, the average Central Electric Power Assn - (MS) customer experienced 895.3 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). Excluding major weather events from that total, that lands within the usual 120–180 minute national benchmark band, roughly on par with typical U.S. distribution-utility performance. SAIFI, the average number of outage events per customer, was 5.53 for the same period, so customers statistically faced roughly 6 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 263.6 minutes; the difference from the headline 895.3 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 Central Electric Power Assn - (MS), which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has increased from 572.6 to 895.3 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
