What mid-pack Berkeley Electric Coop Inc filings show
Berkeley Electric Coop Inc is a member-owned electric cooperative operating in South Carolina under EIA identifier 1613. It reports service to approximately 124,282 customer accounts and generated about $0.43 billion in annual electric revenue, with a service footprint spanning 43 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 Berkeley Electric Coop Inc customer experienced 107.9 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). That keeps this utility below the typical 120–180 minute national benchmark, consistent with a well-hardened distribution system and fast restoration crews. Over the same period, SAIFI (outage events per customer) was 1.19, putting the typical customer at roughly 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 96.9 minutes; the difference from the headline 107.9 shows how much of the outage total came from weather rather than everyday grid issues.
With 4 consecutive years of EIA data (2020–2023), Berkeley Electric Coop Inc's reliability record can be judged on trend rather than one isolated year. SAIDI has improved from 316.0 to 107.9 minutes over that window, a meaningful direction for prospective customers and regulators watching capital investment outcomes.
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.
