Michigan’s power outages aren’t evenly spread across the year — they cluster heavily around severe summer storms and the ice and wind events of winter. That means there’s usually a predictable window before your generator is most likely to actually be needed, and that window is exactly when it’s most useful to confirm it’s ready — not after the sky’s already turned green or the forecast already shows an ice storm arriving.
A generator that performed fine during last year's outage can still be in worse shape today. Batteries degrade gradually, not all at once. A transfer switch can wear a little more with each use. An exercise cycle completing successfully month after month doesn't guarantee the unit would carry a full real-world load the next time it's actually tested by an outage. Storm readiness isn't a one-time achievement — it's a condition that has to be reconfirmed before each season that's likely to test it.
The most effective time to confirm readiness is shortly before Michigan’s two highest-risk windows: early summer, ahead of peak storm season, and early fall, ahead of winter ice and wind events. See our [Seasonal Maintenance Schedule] for the full year-round breakdown — but if you only do this once a year, timing it just before summer storm season gives you the most protection when you’re statistically most likely to need it.
It varies considerably — some severe summer storms develop with only a few hours’ notice, while winter events are often forecast several days out. This is part of why proactive, seasonal readiness matters more than trying to check right before a specific storm.
Not necessarily. A self-test confirms the unit starts under light conditions; it doesn’t confirm the battery would hold up under full starting demand or that the transfer switch and fuel supply would perform under a real, sustained load.
We prioritize storm-preparedness requests as availability allows, but the more advance notice you can give, the more likely we can get to you before the weather arrives. This is part of why checking in early summer and early fall, rather than storm-by-storm, is the more reliable approach.
