Feb. 1, 1966, Lincoln Electric System was formed and a single utility began providing electric energy in and around Lincoln, Nebraska. In November 1970, Lincoln voters approved formation of a semi-autonomous administrative board of local citizens to oversee operations of the nonprofit, customer-owned utility. Today, LES services approximately 200 square miles within Lancaster County in Nebraska, comprising the cities of Lincoln, Prairie Home, Waverly, Walton, Cheney, and Emerald. See a map of the service area.
