Kenwood Transmission Line Upgrade

Kenwood Transmission Line Upgrade

Duke Energy is committed to providing customers with reliable, safe and increasingly clean energy. We’re improving our transmission infrastructure – the backbone of our state’s energy system – powering communities and helping to build the smarter, cleaner energy future that customers want. 

Pinellas County is experiencing rapid growth and increased energy use. To help meet the demand, Duke Energy plans to upgrade and rebuild an existing 3.3-mile transmission line in St. Petersburg from our 40th Street Substation to our 16th Street Substation. The existing line, which is located in road right of way, will be upgraded with stronger, steel poles close to their current locations. These new poles will require less maintenance and be more resilient to extreme weather. This will help to reduce outages and improve overall reliability.

This project is one of several projects in Pinellas County designed to help ensure continued reliability and meet the growing demand for electricity used by homes, businesses and the community.
