What mid-pack City of Sturgis - (MI) filings show

City of Sturgis - (MI) is a municipally-owned utility operating in Michigan under EIA identifier 18252. It reports service to approximately 7,121 customer accounts and generated about $0.03 billion in annual electric revenue, with a service footprint spanning 1 ZIP code. 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 Sturgis - (MI) customer experienced 150.9 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). Excluding major weather events from that total, that places this utility well below the 120–180 minute national benchmark, signaling strong grid hardening and fast restoration practices. The SAIFI figure, which tracks average outage events per customer, came in at 1.07 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 15.4 minutes; the difference from the headline 150.9 shows how much of the outage total came from weather rather than everyday grid issues.

The EIA dataset includes 2 years of continuous reporting (2022–2023) for City of Sturgis - (MI), which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has improved from 163.0 to 150.9 minutes over that window, a meaningful direction for prospective customers and regulators watching capital investment outcomes.
