What long-outage Consumers Energy Co - (MI) filings show
Consumers Energy Co - (MI) is an investor-owned utility operating in Michigan under EIA identifier 4254. It reports service to approximately 1,884,290 customer accounts and generated about $4.67 billion in annual electric revenue, with a service footprint spanning 500 ZIP codes. Investor ownership puts this utility under the regulatory authority of the state public utility commission, which reviews its rate requests and reliability record.
In 2023, the average Consumers Energy Co - (MI) customer experienced 913.0 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). Excluding major weather events from that total, that falls inside the typical 120–180 minute national benchmark, in line with what most U.S. distribution utilities report. The SAIFI figure, which tracks average outage events per customer, came in at 1.37 for the same period, meaning customers statistically saw about 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 176.4 minutes; the difference from the headline 913.0 shows how much of the outage total came from weather rather than everyday grid issues.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for Consumers Energy Co - (MI), which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI climbed from 510.3 to 913.0 minutes over that window, a shift that can point to 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.
