Tempest Substation: Electrical Substation in the United States

Tempest Substation is an operational electrical substation located in the United States, owned and operated by ITC. The facility handles primary voltage of 120 kV and secondary voltage of 13.2 kV, indicating its role in stepping down transmission-level power for distribution. As part of the U.S. electrical infrastructure, Tempest Substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These bodies enforce reliability standards and oversee interstate electricity transmission, ensuring grid stability and security. The substation's location in the Great Lakes region places it within a densely populated and industrially active area, supporting residential, commercial, and industrial loads. Its operation contributes to the reliability of the regional grid, particularly in the context of the Eastern Interconnection.

The substation is situated in an urbanized area of Michigan, near Lake St. Clair. The surrounding environment includes residential and commercial zones, with potential impacts from electromagnetic fields and stormwater runoff. Standard mitigation measures such as proper grounding and containment are typically employed to minimize environmental effects.
