St. Petersburg Area Grid Improvements

51st Street Substation Optimization

Duke Energy is working hard in your community to improve reliability, reduce outages, strengthen the power grid against severe weather and prepare our system to serve a growing area. As part of this commitment, we are conducting multiyear grid improvement projects in the St. Petersburg and Gulfport areas. 

About the Project

We’re upgrading our electric infrastructure in St. Petersburg, including improvements in Gulfport and surrounding areas. Work began in 2022 and will continue in phases through 2023, centering around these primary work objectives:
  • Strengthen the power grid to avoid power outages: Upgrading power lines, poles and essential equipment
  • Improve reliability and reduce outage time: Installing smart, self-healing technology that automatically detects power outages and quickly reroutes power to restore service faster
  • Expanding capacity and preparing the area for sustainable growth: Completing substation improvements, new underground and overhead power lines to provide more capacity to the area
