Nancy Thompson was excited.

“Washington Electric called me last week and told me they would be here, and here they are,” she says. “I think it’s kind of exciting. They came through and cut the trees without cutting the wire. I’ve never seen anything like it.”

About 50% of all power outages are caused by vegetation. That figure varies widely depending on the landscape through which power lines run, and it reaches two-thirds for some Ohio co-ops. Many outages occur during storms when limbs or entire trees fall across electric lines, but others arise less dramatically when branches grow into lines.

In early March, a spring storm ravaged much of the region served by Logan County Electric Cooperative in Bellefontaine.

“System reliability and safety are extremely important,” says Scott Roach, director of engineering services at LCEC. “With every new project, every work plan, it’s always with that in mind.”

Foliage foibles

One of the most significant factors affecting that reliability is the presence of trees. Of course, properly placed trees not only are beautiful to look at, but they also provide tangible benefits: increasing property values, reducing the cost to heat and cool a home, providing privacy, and even cutting stormwater runoff.
