What long-outage Wisconsin Electric Power Co filings show
Wisconsin Electric Power Co is an investor-owned utility operating in Wisconsin under EIA identifier 20847. It reports service to approximately 1,159,300 customer accounts and generated about $3.29 billion in annual electric revenue, with a service footprint spanning 262 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 Wisconsin Electric Power Co customer experienced 272.0 minutes of power interruptions, a measure known as SAIDI, or 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 1.04 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 85.0 minutes; the difference from the headline 272.0 shows how much of the outage total came from weather rather than everyday grid issues.
Wisconsin Electric 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. Over that span, SAIDI rose from 140.0 to 272.0 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
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 Wisconsin Electric 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, Wisconsin Electric Power Co charges more per customer than 67% of them, and is more reliable (lower SAIDI) than 35% 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.
Revenue per customer: $2,835/year · Latest SAIDI: 272.0 minutes/year.
