Marianna Substation is an operational electrical substation located in Marianna, Florida, United States. Owned and operated by Florida Power & Light, a major utility in the region, the substation plays a key role in the local electrical infrastructure. With voltage levels of 115 kV and 12 kV, it is classified as a medium-voltage substation, typical for distribution and sub-transmission networks. The substation operates under the regulatory framework of the United States, which includes NERC reliability standards for grid stability and FERC oversight for interstate transmission. Florida Power & Light, as the operator, adheres to these standards to ensure reliable power delivery. The facility's dual voltage levels indicate its function in stepping down power from transmission to distribution levels, serving both industrial and residential customers in the Marianna area. Environmental considerations for substations like Marianna include electromagnetic field management and oil containment for transformers. Located in the Florida Panhandle, the substation supports the region's energy needs, contributing to grid resilience in an area prone to hurricanes. Its operational status ensures continued service to the community, aligning with FPL's commitment to reliable electricity.
Environmental context
The Marianna Substation is situated in the Florida Panhandle, a region with a humid subtropical climate and vulnerability to hurricanes.
