In response to St. Petersburg’s significant growth, Duke Energy built a new transmission substation to support the retirement of the existing Bayboro facility. A power substation is a facility that's a key part of the national electricity grid, responsible for transmitting electricity reliably and securely at different voltages. Bayboro South GIS Substation is the first gas-insulated substation built in Florida by Duke Energy. Gas-insulation provides more power and allows the substation to occupy a significantly smaller footprint. Aesthetically, the new space appears to be a regular building from the outside, helping it to blend in with surrounding buildings. The covered and elevated enclosure provides additional protection against storms, hurricanes, dust and other environmental threats—all of these protections reducing maintenance, mitigating flood risks, and increasing reliability of service. This substation helps power critical infrastructure such as University of South Florida’s St. Petersburg campus, The Mahaffey Theater – Duke Energy Center for the Performing Arts, Albert Whitted Airport, Johns Hopkins All Children's Hospital, Orlando Health Bayfront Hospital, Duke Energy Operations, Tropicana Field and others. The construction of this substation required a convergence of STEAM principles. Its added capacity prepares us for the future growth of the Innovation District and surrounding areas.
