Clay Substation Project

DP&L has applied to build a new substation in Highland County.

Skip To Side Navigation

The project involves tapping the existing 345 kilovolt (kV) transmission line from the Stuart Substation to the Clinton Substation and building a new greenfield 345 kV substation for the purpose of interconnecting a new solar generator to the Dayton Power and Light transmission system. A "tap" is the process of connecting a new substation by running a new transmission line from the substation to an existing transmission line.
