What long-outage Southside Electric Coop, Inc filings show
Southside Electric Coop, Inc is a member-owned electric cooperative operating in Virginia under EIA identifier 21244. It reports service to approximately 58,834 customer accounts and generated about $0.13 billion in annual electric revenue, with a service footprint spanning 84 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 Southside Electric Coop, Inc customer experienced 271.5 minutes of power interruptions, the industry-standard SAIDI metric (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. The SAIFI figure, which tracks average outage events per customer, came in at 2.44 for the same period, meaning customers statistically saw about 2 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 271.5 minutes, the gap between that figure and the headline 271.5 reveals how much weather, not day-to-day infrastructure, drove outages.
With 4 consecutive years of EIA data (2020–2023), Southside Electric Coop, Inc's reliability record can be judged on trend rather than one isolated year. SAIDI dropped from 354.0 to 271.5 minutes across that span, a direction regulators and prospective customers tend to watch closely.
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.
