Overview
Modesto A. Maidique Substation is an operational 138 kV substation in Miami, Florida, owned and operated by Florida Power & Light. It plays a key role in the regional electrical grid.
Modesto A. Maidique Substation is a 138 kV electrical substation located in Miami, Florida, United States. Owned and operated by Florida Power & Light (FPL), it serves as a critical node in the local transmission network, stepping down high-voltage power for distribution to residential, commercial, and industrial customers in the Miami metropolitan area. Operating at 138 kV, this substation is classified as a high-voltage transmission facility, typical for urban substations that interconnect with the broader grid. As part of FPL's infrastructure, it adheres to North American Electric Reliability Corporation (NERC) reliability standards and Federal Energy Regulatory Commission (FERC) regulations, ensuring stable and secure power delivery. The substation likely employs modern switchgear and automation systems compliant with IEC 61850 standards for efficient grid management. Located in a densely populated urban area, the substation supports the electrical needs of a major city, including critical facilities such as hospitals, schools, and transportation systems. Its operational status contributes to grid resilience in a region prone to hurricanes, where reliable power infrastructure is essential for community safety and economic activity.
Environmental context
The substation is situated in a subtropical urban environment in Miami, where high temperatures and humidity necessitate robust cooling and insulation systems for electrical equipment. The area is vulnerable to hurricanes and tropical storms, requiring infrastructure designed to withstand extreme weather. The substation's location near residential and commercial zones means electromagnetic fields and noise are managed to meet local environmental standards.
