* Timeline and project approvals are 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 over the entire distance of the project. These activities will occur in different locations at different times due to the size of the project and need to optimize the use of resources.

Frequently Asked Questions

  • The Osprey Energy Center is strategically located in Central Florida (i.e., Osceola, Orange, Lake, Sumter and Polk counties) where Duke Energy serves a growing population (i.e., estimated 733,000 customers). The project will enable Duke Energy to deliver additional energy generated at the Osprey Energy Center to our major growth areas in Central Florida and surrounding areas. In addition, the two new 230-kV transmission lines will help avoid line overloads on the existing Duke Energy transmission system by supplying an alternate path of energy flow to the surrounding areas. The new transmission infrastructure will also provide the opportunity for future economic development and growth in the region.

  • The new lines will be built on single concrete or steel poles, about 90 to 110 feet tall.

  • With a stronger smarter grid, this transmission improvement project will directly benefit electric customers in Central Florida with improved reliability. The project will add needed capacity to support increasing demand for electricity for growing communities in the region and will minimize the risk and duration of customer outages.

  • If an easement is needed on private property, a Duke Energy real estate representative will contact the landowner to discuss the easement acquisition process, the location of poles and wires, and potential compensation for an easement. Easement acquisitions will continue through early 2023.

  • Probably the most noticeable portion of construction is vegetation clearing and grading, which is the earliest step. The right of way must be clear during the construction process. Workers also may build access roads during this phase. Crews will then begin the process of pouring structure foundations and installing structures. Neighbors can expect large trucks with drilling equipment 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. Later, crews install ground rods to the structures. Power is typically not affected when the line is energized.

  • Following the installation of poles and wires, our crews work on the final project phase, which is restoration. This work may include leveling, seeding and laying straw on affected areas. Construction materials and debris will be removed, and the right of way will be restored as closely as possible to its original condition. Trees and vegetation removed before construction are not replaced. Periodic vegetation management is done to keep the easement free of incompatible vegetation.
