Osprey to Kathleen Transmission Line
The Osprey to Kathleen 230-kilovolt (kV) transmission line is one of two new transmission lines planned as part of the Polk County Reliability Enhancement Project. The new line will extend from the Osprey Energy Center approximately 26 miles northwest to the existing Kathleen Substation in Polk County. Vegetation removal and construction of the Osprey-Kathleen transmission line will begin spring 2023.
