Overview
Big Bay Substation is an operational electrical substation in Michigan, United States, owned and operated by American Transmission Company. It operates at 138 kV, serving the regional power grid.
Big Bay Substation is an operational electrical substation located in Michigan, United States. Owned and operated by American Transmission Company, the facility plays a role in the regional transmission network, stepping down voltage for local distribution. The substation operates at 138 kV, a common voltage level for subtransmission systems in North America. As part of the U.S. electrical infrastructure, Big Bay Substation operates under the regulatory framework established by the Federal Energy Regulatory Commission (FERC) and adheres to reliability standards set by the North American Electric Reliability Corporation (NERC). The facility's voltage level and ownership by a transmission company indicate its importance in maintaining grid stability and power flow in the region. The substation's location in Michigan's Upper Peninsula places it in a region with a mix of industrial, residential, and natural landscapes. Its role in the grid supports local communities and industries, contributing to the reliable delivery of electricity. The facility's operational status and integration into the broader transmission network underscore its significance in the regional electrical infrastructure.
Environmental context
The Big Bay Substation is situated in Michigan's Upper Peninsula, an area characterized by forests, lakes, and a relatively low population density. The substation's operation at 138 kV is typical for subtransmission facilities that connect to local distribution networks. The environmental context includes potential impacts on local wildlife and habitats, though modern substations are designed with mitigation measures such as oil containment and noise reduction. The facility's location away from dense urban centers reduces some environmental pressures but requires careful management of stormwater runoff and vegetation clearance.
Frequently asked questions
Big Bay Substation is located in Michigan, United States, near the community of Big Bay in the Upper Peninsula. Its coordinates are approximately 46.58° N, -87.42° W.
Big Bay Substation operates at 138 kV (kilovolts), which is a common voltage level for subtransmission systems in the United States, connecting high-voltage transmission lines to local distribution networks.
Big Bay Substation is owned and operated by American Transmission Company (ATC), a major transmission utility in the Midwest that manages high-voltage electric transmission lines and substations.
Substations in the United States, including Big Bay, must comply with reliability standards set by the North American Electric Reliability Corporation (NERC) and are regulated by the Federal Energy Regulatory Commission (FERC) for transmission-level assets.
A 138 kV substation serves as an intermediate point in the electrical grid, stepping down voltage from higher transmission levels (e.g., 345 kV) to lower distribution levels (e.g., 69 kV or 34.5 kV) for delivery to local utilities and end users.
