Brooksville West – Mondon Hill – Bushnell East

Brooksville West – Mondon Hill – Bushnell East Transmission and Substation Project

Project Overview

To help meet the anticipated growth in Hernando and Sumter counties in Florida, Duke Energy is constructing a new transmission circuit, extending existing transmission lines and upgrading other existing transmission lines. We also plan to construct a new Mondon Hill Substation. 


Project Details

Mondon Hill Substation

Build a new 230/115-kilovolt (kV) Mondon Hill Substation at Mondon Hill Road and Old Jasmine Drive in South Brooksville, Fla.

Transmission Line Projects

Bushnell East to Mondon Hill

Add a new 230-kV circuit by:

  • Upgrading the existing 69-kV double-circuit transmission lines and adding a new 230-kV line on collocated triple-circuit structures for approximately 2 miles within the utility existing easement area coming out of the Bushnell East Substation heading west. 
  • Upgrading the existing 69-kV single-circuit transmission line and adding a 230-kV line on collocated double-circuit structures for approximately 17.5 miles within the existing easement area.

Brooksville to Mondon Hill

Add a new 230-kV circuit by:

  • Upgrading the existing transmission lines with a 230-kV/115-kV/69-kV triple-circuit pole line and 115-kV/115-kV/69-kV/69-kV quad-circuit pole for 1.4 miles within the existing easement area.

Brooksville West to Brooksville

  • Reconfigure the existing Brooksville West to Brooksville 115-kV double-circuit transmission line to bypass the Brooksville Substation and end at Mondon Hill Substation.
  • Upgrade one of the existing 115-kV transmission lines to a 230-kV line from the Brooksville West line to the Brooksville Substation.
