Little River Substation: 138 kV Substation in Florida, United States

Little River Substation is an operational electrical substation located in Florida, United States. Owned and operated by Florida Power & Light, it operates at a voltage of 138 kV, classifying it as a high-voltage transmission substation that supports the stability and reliability of the local power grid. The substation falls under the regulatory oversight of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for bulk power systems. As part of Florida Power & Light's extensive network, it is integrated into the state's growing energy infrastructure, serving urban and suburban areas in the Miami metropolitan region. This facility contributes to grid resilience by stepping down transmission voltages for distribution or interconnecting with other transmission lines. Its location in a densely populated area underscores its importance for meeting electricity demand and supporting economic activity. The substation's operational status ensures continued service to the community.

The substation is situated in an urbanized area of Miami-Dade County, where electrical infrastructure must withstand tropical weather conditions, including hurricanes and high humidity. The facility's design likely incorporates flood mitigation and corrosion-resistant materials. Its operation supports the integration of renewable energy sources, such as solar, into the grid, aligning with Florida's growing clean energy targets.
