Ely Substation - 138 kV Electrical Substation in Florida, United States

Ely Substation is an operational electrical substation located in the United States, owned and operated by Florida Power & Light. The facility operates at a voltage of 138 kV, classifying it as a medium-voltage substation within the transmission and distribution network. It plays a key role in stepping down power for local distribution or interconnecting regional grid segments. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for the bulk power system. Florida Power & Light, a major investor-owned utility, manages a large portfolio of generation, transmission, and distribution assets across Florida. The 138 kV voltage level is typical for subtransmission systems that feed distribution substations or large industrial customers. As part of the Florida grid, Ely Substation contributes to the reliability of electricity supply in the region. Its location in a densely populated area of southeastern Florida underscores its importance in maintaining grid stability and meeting the energy demands of residential, commercial, and industrial users. The substation's operational status ensures continued support for the local power infrastructure.

The substation is located in a subtropical coastal environment in southeastern Florida, where high humidity and salt-laden air can accelerate corrosion of electrical equipment. The region is also prone to hurricanes and severe storms, which pose risks to overhead transmission lines and substation infrastructure. These environmental factors necessitate robust design and maintenance practices to ensure grid reliability.
