Wisconsin Electric Power Co

What This Utility Data Tells You

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.
