AES Ohio is proposing upgrades to the local power grid, known as the Marysville Area Improvement Project (the "Project"). The Project includes constructing a new, approximately 5-mile, 138kV transmission line that would run from AES's existing Darby Substation in Marysville to a new 138kV Substation, called Meadow. The existing Darby Substation would also be expanded. This new transmission line would interconnect with the First Energy transmission line. A map showing the project area and several potential route options for the new transmission line is shown below.
Why is this project needed?
AES Ohio is dedicated to serving the load growth near the Darby Substation in the Marysville area. Customer load requests necessitate a significant increase in transmission support by 2028. These network enhancements are designed to serve the new load and provide increased capacity, flexibility, and redundancy for Union County and its communities.
