H-frame structures will be replaced with stronger steel monopole structures which will require less maintenance, have a smaller footprint, and be more resilient against severe weather conditions.

The work will take place within existing Duke Energy easement areas.

*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.
