ComEd's Grand Prairie Gateway Project Is Complete

The Illinois Commerce Commission announced on Oct. 22, 2014 that it approved ComEd’s Grand Prairie Gateway Project, a new transmission line that extends for 60 miles across Ogle, DeKalb, Kane and DuPage Counties. This new line creates immediate customer savings by reducing grid congestion, increasing customers’ access to lower-cost generation, including wind power, and will reduce carbon emissions by 473,000 tons over 15 years. Construction began in June 2015 and the line was placed in service in the second quarter of 2017.
