Millcreek 138kV Extension Project

DP&L has applied to extend an existing transmission line to serve an expansion of the Millcreek 138/12kV substation.

Skip To Side Navigation

DP&L plans to extend the 138kV transmission line currently connecting the Sidney Substation to the Eldean Substation in order to serve an expansion of the Millcreek 138/12kV Substation. The Millcreek Substation, located in Sidney, Ohio, is currently connected to the existing Sidney-Eldean 138kV line. However, DP&L plans to build a new transmission extension to loop in and out of the Millcreek Substation. The 138kV extension will be 0.2 miles (or less) built on its own poles and the lines will be located in Sidney, Shelby County, Ohio. The line extension will mostly share the same right-of-way as the existing 138kV Millcreek tap. The project will help to provide more reliable service to this area.
