City of Dover - (OH) is a municipally-owned utility operating in Ohio under EIA identifier 5336. It reports service to approximately 6,868 customer accounts and generated about $0.03 billion in annual electric revenue, with a service footprint spanning 2 ZIP codes. Being municipally owned, the utility answers to a local board or city council rather than a state commission, and carries a federal income tax exemption.
In 2023, the average City of Dover - (OH) customer experienced 18.4 minutes of power interruptions, a metric called SAIDI (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 0.20 for the same period, meaning customers statistically saw about 0 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 16.0 minutes; the difference from the headline 18.4 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 City of Dover - (OH), which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has improved from 48.9 to 18.4 minutes over that window, a meaningful direction for prospective customers and regulators watching capital investment outcomes.
