Martin Road Substation - Operational 138 kV Substation in the United States

Martin Road Substation is an operational electrical substation located in the United States, with coordinates 43.740042, -88.431159. The facility operates at a voltage of 138 kV, placing it in the medium-to-high voltage range typical for sub-transmission and distribution substations. As a substation, it serves as a node in the electrical grid, stepping down voltage for local distribution or interconnecting transmission lines. The substation operates under the regulatory framework of the United States, which includes NERC reliability standards for grid stability and FERC oversight for transmission-level assets. The 138 kV voltage level is common for sub-transmission systems that supply industrial and large commercial customers, as well as feed distribution networks. The facility's location in the Midwest suggests it may be part of a regional grid managed by a balancing authority such as MISO. Martin Road Substation contributes to the electrical infrastructure by ensuring reliable power delivery to the surrounding area. Its operational status indicates ongoing grid support, and its voltage level suggests it is critical for local load centers. The substation's role in the broader grid network underscores its importance for maintaining system stability and meeting electricity demand in the region.

The substation is located in a region with a temperate climate, typical of the Midwest United States. Electrical infrastructure in this area must withstand seasonal weather variations, including winter storms and summer heat waves, which can affect grid reliability. The facility's urban or rural setting influences its environmental impact, with substations in populated areas requiring careful management of electromagnetic fields and noise. The 138 kV voltage level indicates moderate environmental considerations, such as right-of-way maintenance and vegetation management to prevent outages.
