What mid-pack Choptank Electric Cooperative, Inc filings show
Choptank Electric Cooperative, Inc is a member-owned electric cooperative operating in Maryland under EIA identifier 3503. It reports service to approximately 56,543 customer accounts and generated about $0.16 billion in annual electric revenue, with a service footprint spanning 76 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 Choptank Electric Cooperative, Inc customer experienced 111.2 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. SAIFI, the average number of outage events per customer, was 1.25 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 111.2 minutes; the difference from the headline 111.2 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 Choptank Electric Cooperative, Inc, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has improved from 225.6 to 111.2 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.
