Overview
Duffield Substation is an operational electrical substation in Michigan, United States, owned and operated by Consumers Energy. It handles voltages of 138 kV and 14.4 kV, serving the local grid.
Duffield Substation is an operational electrical substation located in Michigan, United States. Owned and operated by Consumers Energy, the facility plays a key role in the regional power distribution network. The substation is part of the larger electrical infrastructure that supports residential, commercial, and industrial customers in the area. The substation operates at voltage levels of 138,000 volts (138 kV) and 14,400 volts (14.4 kV), indicating its role in both transmission and distribution. The 138 kV level connects to the high-voltage transmission grid, while the 14.4 kV level serves local distribution. As a substation in the United States, it operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and is subject to Federal Energy Regulatory Commission (FERC) oversight for reliability standards. Duffield Substation contributes to grid stability and reliability in its region. Its location in Michigan places it within the footprint of the Midcontinent Independent System Operator (MISO), which manages the regional transmission grid. The substation's operational status ensures continued power delivery to the surrounding community, supporting local economic activity and daily life.
Environmental context
The substation is situated in a region with a temperate climate, where seasonal weather patterns can impact grid operations. Its location in Michigan, near the Great Lakes, may require infrastructure designed to withstand snow, ice, and temperature extremes. The facility's voltage levels and role in the grid influence its environmental footprint, with higher voltage equipment typically requiring more robust insulation and safety measures. Urban or rural siting affects land use and potential electromagnetic field considerations.
