What long-outage Monongahela Power Co filings show
Monongahela Power Co is an investor-owned utility operating in West Virginia under EIA identifier 12796. It reports service to approximately 396,758 customer accounts and generated about $1.15 billion in annual electric revenue, with a service footprint spanning 394 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 Monongahela Power Co customer experienced 744.0 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). Excluding major weather events from that total, that is substantially above the 120–180 minute national benchmark, indicating either storm-prone geography, aging infrastructure, or extended restoration windows. The SAIFI figure, which tracks average outage events per customer, came in at 2.57 for the same period, meaning customers statistically saw about 3 distinct interruptions that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 357.2 minutes, and the spread against the headline 744.0 indicates how much weather, versus routine infrastructure, drove the outage total.
Monongahela Power Co has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. SAIDI has increased from 513.0 to 744.0 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
Based on this utility's own EIA Form 861 reliability record -- baseline (major-event- excluded) outage duration, total outage duration, and outage frequency -- each benchmarked against every reporting utility nationwide. Not a measure of electricity rates or customer service, which this portal does not track.

Price vs. reliability
Where Monongahela Power Co sits on price vs. reliability
Among the 781 U.S. utilities large enough to report both revenue per customer and a recent outage record, Monongahela Power Co charges more per customer than 70% of them, and is more reliable (lower SAIDI) than 12% of them, placing it in the quadrant where it pays more but is LESS reliable, a premium price without a reliability payoff. Revenue per customer and outage minutes are independent figures: paying more does not guarantee fewer outages.
