Overview
40th Street Substation DUKE is an operational electrical substation in St. Petersburg, Florida, owned and operated by Duke Energy. It operates at 115 kV, serving the local grid.
40th Street Substation DUKE is an electrical substation located in St. Petersburg, Florida, United States. Owned and operated by Duke Energy, the facility is currently operational and plays a role in the regional power distribution network. The substation operates at a voltage of 115 kV, which is typical for sub-transmission or distribution-level infrastructure in the United States. As part of Duke Energy's grid, the substation is subject to North American Electric Reliability Corporation (NERC) reliability standards and Federal Energy Regulatory Commission (FERC) regulations for transmission-level assets. The 115 kV voltage class indicates it likely serves as a distribution substation, stepping down power from higher transmission voltages for local delivery. In Florida, such substations are critical for maintaining grid stability in urban and suburban areas. The substation's location in St. Petersburg, a coastal city in the Tampa Bay area, places it in a region with growing electricity demand due to population and economic activity. Its operational status ensures continued service to residential, commercial, and industrial customers. The facility contributes to the reliability of the local electrical infrastructure, supporting the broader grid's resilience.
Environmental context
The substation is situated in an urban area of St. Petersburg, Florida, a coastal city with a subtropical climate. The local environment is characterized by high humidity, frequent thunderstorms, and the risk of hurricanes, which can impact electrical infrastructure. The 115 kV voltage level and urban location mean the substation is critical for grid stability, especially during extreme weather events. Duke Energy likely employs robust design and maintenance practices to mitigate environmental risks.
