What long-outage Altamaha Electric Member Corp filings show
Altamaha Electric Member Corp is a member-owned electric cooperative operating in Georgia under EIA identifier 407. It reports service to approximately 21,672 customer accounts and generated about $0.06 billion in annual electric revenue, with a service footprint spanning 24 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 Altamaha Electric Member Corp customer experienced 424.7 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. 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 2.00 for the same period, so customers statistically faced roughly 2 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 299.6 minutes; the difference from the headline 424.7 shows how much of the outage total came from weather rather than everyday grid issues.
With 4 consecutive years of EIA data (2020–2023), Altamaha Electric Member Corp's reliability record can be judged on trend rather than one isolated year. Over that span, SAIDI rose from 149.6 to 424.7 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
Based on this utility's own EIA Form 861 reliability record -- baseline (major-event- excluded) outage duration, total outage duration, and outage frequency -- each benchmarked against every reporting utility nationwide. Not a measure of electricity rates or customer service, which this portal does not track.

Price vs. reliability
Where Altamaha Electric Member Corp sits on price vs. reliability
Among the 781 U.S. utilities large enough to report both revenue per customer and a recent outage record, Altamaha Electric Member Corp charges more per customer than 74% of them, and is more reliable (lower SAIDI) than 24% of them, placing it in the quadrant where it pays more but is LESS reliable, a premium price without a reliability payoff. Revenue per customer and outage minutes are independent figures: paying more does not guarantee fewer outages.
