What long-outage Excelsior Electric Member Corp filings show
Excelsior Electric Member Corp is a member-owned electric cooperative operating in Georgia under EIA identifier 5905. It reports service to approximately 25,288 customer accounts and generated about $0.06 billion in annual electric revenue, with a service footprint spanning 21 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 Excelsior Electric Member Corp customer experienced 922.0 minutes of power interruptions, a metric called SAIDI (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. Excluding major event days (hurricanes, ice storms), SAIDI drops to 205.6 minutes, the gap between that figure and the headline 922.0 reveals how much weather, not day-to-day infrastructure, drove outages.
With 4 consecutive years of EIA data (2020–2023), Excelsior Electric Member Corp's reliability record can be judged on trend rather than one isolated year. Over that span, SAIDI rose from 188.1 to 922.0 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.

Revenue per customer and outage minutes are independent figures: paying more does not guarantee fewer outages.
