Construction has progressed at ComEd’s Itasca Substation expansion project, which is part of a long-range plan to meet an anticipated need for more power in the western O’Hare region. ComEd crews have braved cold temperatures and winter weather to keep the project on-schedule. The Itasca substation expansion project will begin supporting economic development growth in a variety of sectors in Cook and DuPage Counties starting June 1, 2018.
