Overview
Highway 42 Substation is an operational electrical substation in Mississippi, United States, operated by Mississippi Power. It operates at a voltage of 115 kV, serving as a key node in the regional transmission grid.
Highway 42 Substation is an operational electrical substation located in Mississippi, United States. Owned and operated by Mississippi Power, a subsidiary of Southern Company, this facility plays a role in the regional transmission network. The substation operates at a voltage of 115 kV, which is typical for sub-transmission and distribution-level infrastructure in the United States. As part of the U.S. electrical grid, Highway 42 Substation operates under the regulatory framework established by the Federal Energy Regulatory Commission (FERC) and the North American Electric Reliability Corporation (NERC). These bodies set reliability standards for the bulk power system, including substation automation and protection systems. The 115 kV voltage level places this substation in a medium-voltage category, often used to distribute power to industrial and large commercial customers. The substation's location in Mississippi supports the local grid stability and electricity distribution for the surrounding area. Its operational status ensures continued service to the community, contributing to the reliability of the regional power supply. Mississippi Power's oversight aligns with industry standards for maintenance and safety.
Environmental context
The substation is situated in a rural area of Mississippi, where the local environment includes mixed forest and agricultural land. Electrical infrastructure at this voltage level typically has a localized footprint, with minimal direct environmental impact beyond land use for the facility. The surrounding ecosystem may benefit from standard vegetation management practices that prevent interference with power lines.
