Overview
National Substation is an operational electrical substation in the United States, owned and operated by American Transmission Company. It operates at a voltage of 138 kV, serving grid stability in the region.
National Substation is an operational electrical substation located in the United States, owned and operated by American Transmission Company. The facility plays a key role in the regional power grid, with a voltage level of 138 kV, classifying it as a medium-voltage substation typical for distribution and sub-transmission networks. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), ensuring compliance with reliability standards for transmission-level assets. As part of the American Transmission Company's network, it supports the integration of generation sources and load centers in the Midwest region. Environmental and operational significance includes its contribution to grid stability and power delivery in the area. The substation's location in a rural setting minimizes direct environmental impact, while its role in the transmission system supports renewable energy integration and reliable electricity supply to communities.
Environmental context
The substation is situated in a rural area of the Upper Peninsula of Michigan, characterized by forests and low population density. Its operation involves minimal land use change, and the 138 kV voltage level indicates moderate electromagnetic field emissions. The facility's design and maintenance follow NERC standards to mitigate environmental risks such as oil spills from transformers.
