This project is one of three projects to help strengthen the reliability of the transmission grid in the areas of Marion, Levy and Alachua counties. The existing H-frame structures will be replaced with steel structures that will require less maintenance, have a smaller footprint, and be more resilient to weather conditions.

The work will take place within existing Duke Energy easements.

The existing H-frame structures will be replaced with taller single-pole structures as shown above.
The voltage will remain the same.


  • Preconstruction work, including surveying, soil boring and staking

    Begins late 2022

  • Vegetation removal

    Summer 2023

  • Transmission line construction

    Begins late 2023

  • Project completion

    Summer 2024

*Timeline is subject to change based on permitting timelines, additional scope development, weather conditions or other uncontrollable events. Factors such as weather, availability of crews and equipment or unforeseen circumstances may impact the schedule. Many of the activities associated with the design, engineering, and construction of the transmission lines may overlap and do not necessarily happen in a sequential manner. These activities will occur in different locations at different times based on the size of the project and need to optimize the use of resources.

Frequently Asked Questions

  • The existing 8.8-mile line will be rebuilt within the Duke Energy easement between the Archer Substation at 12120 S.W. Archer Road and the Williston North Substation at 4991 Northeast Highway 41.

  • As Florida’s population grows, so do its energy needs. The transmission system in Florida is used by all utilities in the state and their customers. The rebuilt transmission line will help strengthen reliability to meet the growing demand and will help enhance the ability of Duke Energy and other utilities to provide reliable energy to homes, community facilities and businesses in the region.

  • Transmission lines are power lines that carry electricity from power plants to substations, which then deliver the energy to our communities and to other utilities within the state.

  • Current construction plans call for the rebuilt transmission line to be suspended on steel single-pole structures. The old H-frame structures will be removed. The average height of the new steel or concrete transmission poles is 160 feet, about 30 feet higher than the current structures.

  • Trees are part of the natural beauty of Florida, but trees and other vegetation are also one of the leading causes of power outages for utilities. Since the existing line is already in a Duke Energy easement, the corridor has been maintained to keep it free of incompatible vegetation. Our team will evaluate what vegetation clearing needs to be done to accommodate access and equipment for construction and to continue to operate the line reliably. We plan for the safe and unobstructed access to the easement for our construction crews, and for any future maintenance on the transmission line. Duke Energy representatives will be in direct contact with property owners in advance of vegetation removal.

  • Construction crews generally work weekdays during daylight hours and carry identification showing their affiliation with Duke Energy. The crews use a variety of vehicles and equipment to build concrete foundation and to place and erect poles and string wires. There may be temporary traffic lane/trail closings along the route. Neighbors can expect large equipment including cranes and excavators or a concrete mixer in the right of way. The concrete is poured at the bottom of a deep hole to form the foundation. The structure materials arrive in sections and may be assembled on the ground before being installed. The final construction activity is wire stringing. Trucks carrying large reels of conductor are typically used, with a winch to pull the conductor through. Linemen attach the wires to the structures. Following construction, the area will be restored as closely as possible to its original condition.

  • Preliminary preparations for the project began in 2021. Vegetation work is scheduled to begin in summer 2023 with the construction expected to start in late summer 2023 and conclude in summer 2024.
