Wheeling Power Co is an investor-owned utility operating in West Virginia under EIA identifier 20521. It reports service to approximately 41,400 customer accounts and generated about $0.38 billion in annual electric revenue, with a service footprint spanning 17 ZIP codes. As an investor-owned utility, it operates under state public utility commission oversight that reviews rate cases and reliability performance.
In 2023, the average Wheeling Power Co customer experienced 777.3 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). That exceeds the 120–180 minute national benchmark by a wide margin, a pattern often tied to severe weather exposure, older infrastructure, or longer repair windows. The SAIFI figure, which tracks average outage events per customer, came in at 2.25 for the same period, meaning customers statistically saw about 2 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 593.8 minutes, the gap between that figure and the headline 777.3 reveals how much weather, not day-to-day infrastructure, drove outages.
With 4 consecutive years of EIA data (2020–2023), Wheeling Power Co's reliability record can be judged on trend rather than one isolated year. Over that window, SAIDI moved from 841.6 down to 777.3 minutes, a trend worth noting for anyone weighing capital investment outcomes.
