What short-outage Wyandotte Municipal Serv Comm filings show

Wyandotte Municipal Serv Comm is a municipally-owned utility operating in Michigan under EIA identifier 21048. It reports service to approximately 12,775 customer accounts and generated about $0.03 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 Wyandotte Municipal Serv Comm customer experienced 12.4 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. That places this utility well below the 120–180 minute national benchmark, signaling strong grid hardening and fast restoration practices. SAIFI, the average number of outage events per customer, was 0.08 for the same period, so customers statistically faced roughly 0 distinct interruptions that year.

With 4 consecutive years of EIA data (2020–2023), Wyandotte Municipal Serv Comm's reliability record can be judged on trend rather than one isolated year. SAIDI has improved from 75.1 to 12.4 minutes over that window, a meaningful direction for prospective customers and regulators watching capital investment outcomes. Note: this figure is unusually low compared to typical U.S. utility performance and may reflect an incomplete EIA filing for this year rather than a genuine reliability improvement -- treat with caution and cross-check against Wyandotte Municipal Serv Comm's other reported years.
