What short-outage City of Westerville - (OH) filings show

City of Westerville - (OH) is a municipally-owned utility operating in Ohio under EIA identifier 20477. It reports service to approximately 17,942 customer accounts and generated about $0.05 billion in annual electric revenue, with a service footprint spanning 6 ZIP codes. Municipal ownership means a local board or city council typically oversees this utility, and it is exempt from federal income tax.

In 2023, the average City of Westerville - (OH) customer experienced 44.6 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). Excluding major weather events from that total, that keeps this utility below the typical 120–180 minute national benchmark, consistent with a well-hardened distribution system and fast restoration crews. SAIFI, the average number of outage events per customer, was 0.52 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 17.5 minutes, and the spread against the headline 44.6 indicates how much weather, versus routine infrastructure, drove the outage total.

City of Westerville - (OH) has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. SAIDI dropped from 123.2 to 44.6 minutes across that span, a direction regulators and prospective customers tend to watch closely.
