Monongahela Power Co

What This Utility Data Tells You

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.
