Alliant Energy will be in the Grinnell area during the fall trimming trees around their high-voltage power lines. To help limit weather-related interruptions or outages, Alliant Energy regularly trims trees that are conflicting with power lines. They trim trees along primary transmission and distribution lines on a four- to five-year cycle and are granted permission to trim trees under franchise and easement agreements with the communities they serve.

Their crews, which include both Alliant Energy and contract workers, follow standards approved by the National Arbor Day Foundation to preserve the health of the trees.
