What mid-pack City of Bay City - (MI) filings show
City of Bay City - (MI) is a municipally-owned utility operating in Michigan under EIA identifier 1366. It reports service to approximately 20,343 customer accounts and generated about $0.04 billion in annual electric revenue, with a service footprint spanning 4 ZIP codes. Being municipally owned, the utility answers to a local board or city council rather than a state commission, and carries a federal income tax exemption.
In 2023, the average City of Bay City - (MI) customer experienced 106.2 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). 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 0.60 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 59.3 minutes; the difference from the headline 106.2 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 City of Bay City - (MI), which lets you see whether reliability is trending up or down rather than judging from a single snapshot. Over that window, SAIDI moved from 164.3 down to 106.2 minutes, a trend worth noting for anyone weighing capital investment outcomes.
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.
