After a Twin Cities Storm: What to Check Electrically First

Published October 31, 2026 · Intech Corporation · Twin Cities, MN

After a storm knocks your power out, the safe moves are simple: stay away from any line on the ground no matter how harmless it looks, let the breakers reset on their own once utility power is stable, and walk the outside of your house looking for obvious damage before you assume everything's fine. The dangerous stuff — a cracked weatherhead, a scorched meter base, a panel that took water — isn't something to poke at yourself. That's a call to Intech or, if a line is actually down, a call toand Xcel Energy first.

Minnesota doesn't usually get October tornado watches, but that's exactly what happened on October 28, when a slight risk of severe weather turned into large hail, damaging winds, and isolated tornado chances stretching from the Twin Cities metro into east-central Minnesota and northwest Wisconsin. Some spots saw hail up to three inches across in central Minnesota, and gusts in themph range weren't unusual in the warned areas. The last time the state saw an October tornado outbreak at all was 2021, when nine touched down in a single month, so this kind of late-season severe weather is rare but not unheard of.

Rare or not, storms like this are exactly when we get the call volume that tells us where the weak points are in Twin Cities electrical systems. A straight-line wind event does three things to a house: it rips tree limbs into service drops, it drives rain sideways into places that are normally dry, and it forces the utility grid to switch and reroute power in ways that can send a rough jolt through your system when it comes back on. None of that is exotic. It's just physics meeting an aging service mast or a panel that was already marginal before the wind ever picked up.

Downed Lines: The One Absolute Rule

If you see a line on the ground, in a tree, or draped over a fence after a storm, treat it as energized every single time, even if it's not sparking and even if the power in your house is already out. A downed conductor can still carry lethal voltage, and ground conditions after heavy rain make it worse, not better, because wet soil conducts. Keep kids and pets well back, don't drive over a line, and don't try to move it with a broom handle or anything else — that's a myth that gets people killed.

Calland report it, then call Xcel Energy or your local utility so they can de-energize and respond. This isn't something Intech or any electrical contractor handles directly — downed service conductors and damaged utility equipment on the pole side belong to the utility. We come in on the house side, once the line is confirmed safe and power is restored to the neighborhood.

Why the Power Coming Back On Can Be Its Own Problem

A lot of the damage we see after storms doesn't happen during the storm itself. It happens during restoration, when the utility re-energizes a circuit that's been de-energized and re-energized multiple times, sometimes with voltage swings while crews are isolating damage and switching between feeders. That's rough on anything plugged in, and it's rougher on electronics, furnace control boards, and garage door openers than most people expect.

If you noticed lights flickering or dimming in waves as power came back rather than snapping on clean, that's worth paying attention to. A whole-home surge protective device at the panel is built for exactly this scenario, and Minnesota's adopted code now requires one on new panel installs, which tells you something about how seriously the industry takes storm-driven surges. If you don't have one and you just rode out a rough restoration, it's a reasonable time to ask about adding it.

The Visual Walk-Around You Can Safely Do

Once the storm's past and utility power is confirmed stable, a slow walk around the outside of the house tells you a lot without opening anything up. You're looking for things that are obviously wrong, not diagnosing anything yourself.

• The weatherhead and service mast where the utility line attaches to your house — look for it pulled loose, bent, or leaning away from the wall.
• The meter base — any scorch marks, melted plastic, or a meter that's visibly crooked or hanging.
• Tree limbs resting on the service drop or on the mast itself, even if nothing looks damaged yet.
• Outdoor outlets, light fixtures, or a generator inlet that took standing water during the storm.
• A breaker in the panel that's tripped and won't reset, or one that resets once and trips again immediately.

One Reset Is Fine. A Pattern Isn't.

It's perfectly safe to reset a tripped breaker or a tripped GFCI outlet once, the normal way, and see if it holds. Storms trip breakers for boring reasons all the time, a brief surge, a motor restarting hard, nothing wrong at all. But if a breaker won't hold a reset, if it trips again within seconds, or if you smell anything burning or hot-plastic around the panel, stop resetting it and call us instead. That pattern usually means a fault somewhere downstream, and repeatedly forcing a breaker closed on an active fault is how panels get damaged and how fires start.

Basements and Backup Power After a Storm Like This

The same storm system that brings down a line is often the one dumping enough rain to flood a basement right when the sump pump needs power the most. If this storm had you watching your sump pit nervously during an outage, it's worth reading up on battery backup options for sump pumps before the next one rolls through. And if you're already running a generator during outages, make sure it's connected through a proper transfer switch or interlock kit rather than a cheater cord into an outlet. Backfeeding a generator the wrong way can send power down the line toward the exact utility crews working to restore your neighborhood, which is the last thing you want during storm cleanup.

When It's the Utility's Job vs. Ours

A fast way to sort this out: anything from the meter out to the pole, including the drop line and the transformer, belongs to the utility. Anything from the meter into your house, the panel, the wiring, the devices, is yours, and that's our territory. If you're not sure which side a problem is on, that's a normal question and not a dumb one. Call us and describe what you're seeing; if it turns out to be a utility-side issue we'll tell you straight and point you to Xcel instead of running up a bill for something we can't fix.
