Can Summer Storms Cause Power Surges?

It’s a question many homeowners ask when their lights flicker or electronics suddenly malfunction after a storm. The short answer is a resounding yes. Summer storms bring a unique set of electrical risks that can wreak havoc on your home’s power supply.

Lightning: The Big Bad Wolf of Power Surges

When you think of summer storms, lightning often comes to mind. This powerful natural phenomenon is a major cause of sudden and intense power surges. A direct lightning strike is devastating, but even strikes miles away can cause problems.

How Lightning Creates Surges

Lightning is an enormous electrical discharge. When it hits a power line, a utility pole, or even the ground near underground cables, it can send a massive surge of electricity racing through the electrical grid. This surge doesn’t just stop at the nearest transformer; it can travel for miles.

Your home is connected to this grid. So, when that excess electricity hits the lines feeding your house, it can force its way into your wiring. This sudden influx of power is a power surge. It’s like a tidal wave of electricity overwhelming your home’s normal flow.
