Dayton Power & Light Co

What This Utility Data Tells You

Dayton Power & Light Co is an investor-owned utility operating in Ohio under EIA identifier 4922. It reports service to approximately 213,300 customer accounts and generated about $0.43 billion in annual electric revenue, with a service footprint spanning 218 ZIP codes. Because it is investor-owned, the state public utility commission oversees its rate cases and reliability performance rather than a local board.

In 2023, the average Dayton Power & Light Co customer experienced 170.5 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 0.99, putting the typical customer at roughly 1 distinct interruption that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 96.2 minutes, and the spread against the headline 170.5 indicates how much weather, versus routine infrastructure, drove the outage total.

With 4 consecutive years of EIA data (2020–2023), Dayton Power & Light Co's reliability record can be judged on trend rather than one isolated year. SAIDI dropped from 174.3 to 170.5 minutes across that span, a direction regulators and prospective customers tend to watch closely.
