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 your growing area. As part of this commitment, we are conducting major 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 will be conducted in phases through 2022 and will center 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
