Duke Energy plans new 230-kV substation, two 230-kV lines in Florida

Duke Energy (NYSE:DUK) on May 4 said that in light of increasing electricity demand, as well as the need to improve reliability and ensure a resilient system during storms, the company plans to build a new transmission substation at the Osprey Energy Center site in Polk County, Fla., and two new 230-kV transmission lines.

Florida’s energy demand is expected to grow by an estimated 10% in the next decade, the company noted. Once built, the new infrastructure will improve reliability for customers served by Duke Energy and other area utilities, including Lakeland Electric and Tampa Electric Company, Duke Energy said.

A company spokesperson on May 11 told TransmissionHub that the new 230-kV switching substation will be named the Osprey substation.

The new Kathleen 230-kV transmission line will extend from the Osprey Energy Center about 30 miles west to the existing Kathleen substation, while the new Haines City 230-kV transmission line will extend from the Osprey Energy Center about 24 miles east to the existing Haines City East substation, Duke Energy said in its statement.

The company spokesperson confirmed that informational meetings designed for the public to learn more about the project and to share comments were held on May 8 and May 10.

The company noted in its statement that it is in the beginning stages of selecting routes for the lines, and that at this time, only preliminary routes have been identified in order to seek input from the public. Another informational meeting will be held on May 15 in Winter Haven, Fla., the company said.

The cost of the transmission lines and planned substation will ultimately depend on the specific route, engineering and construction, the spokesperson said.

Once a preferred route is chosen, the route will be evaluated to determine which applicable state and federal permits will be required, the spokesperson said, adding that all local, state and federal requirements will be met. The project may require right of way use permits, as well as permits related to erosion and sediment control/storm water quality, and protected species and wetlands, if determined applicable, the spokesperson said. Final design, specific pole locations, and the time of construction will be required to make those determinations, she said.

Construction on the project is scheduled to begin in 2021, the company said in its statement, adding that the project is expected to be in service in 2024.
