Delaware Electric Cooperative is a member-owned electric cooperative operating in Delaware under EIA identifier 5070. It reports service to approximately 116,535 customer accounts and generated about $0.23 billion in annual electric revenue, with a service footprint spanning 36 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 Delaware Electric Cooperative customer experienced 83.1 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. That places this utility well below the 120–180 minute national benchmark, signaling strong grid hardening and fast restoration practices. The SAIFI figure, which tracks average outage events per customer, came in at 1.29 for the same period, meaning customers statistically saw about 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 68.1 minutes; the difference from the headline 83.1 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 Delaware Electric Cooperative, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has improved from 292.1 to 83.1 minutes over that window, a meaningful direction for prospective customers and regulators watching capital investment outcomes.
