Owned by the City of Homestead, it serves as a key node in the local electrical infrastructure, stepping down transmission-level voltage for distribution to residential and commercial customers. The substation operates at 138 kV, a common voltage level for sub-transmission and distribution substations in the United States. As part of the U.S. grid, it falls under the regulatory oversight of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), ensuring compliance with reliability standards. The facility is situated in a suburban area of Miami-Dade County, reflecting typical infrastructure for growing urban regions. McMinn Substation plays a critical role in maintaining grid reliability for Homestead and surrounding areas. Its operation supports the local economy and community services, particularly during peak demand periods. Its continued operational status indicates ongoing maintenance and integration into the regional power network.

The substation is located in a subtropical climate zone, where high temperatures and humidity can affect equipment performance and longevity. The area is prone to hurricanes, requiring robust infrastructure design to withstand extreme weather events. The substation's urban setting means it must manage potential electromagnetic field impacts and visual integration with the community, while supporting the growing energy demands of the region.
