ICC Approves ComEd's Grand Prairie Gateway Project

The Illinois Commerce Commission announced Oct. 22 that it has approved ComEd’s Grand Prairie Gateway Project, a new transmission line that will extend for 60 miles across Ogle, Dekalb, Kane and DuPage Counties. The new line will create 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 is scheduled to begin in the second quarter of next year and the line is expected to be in service in 2017.

High voltage electricity is moved across the electric grid by transmission lines. Just like highways that don’t have enough lanes, transmission lines with insufficient capacity become congested, reducing efficiencies and increasing  costs of delivering power. PJM Interconnection, the independent regional transmission grid operator and planner for the ComEd service territory, has approved the Grand Prairie Gateway Project as the best solution for addressing current system congestion and ensuring the continued efficient flow of electricity across northern Illinois.
