Allerton Substation | We Energies | 138 kV Electrical Infrastructure in the United States

Allerton is a substation located in the United States, owned and operated by We Energies. The facility operates at a voltage of 138 kV, placing it within the typical range for sub-transmission and distribution substations that serve local industrial and residential loads. As part of the U.S. electrical infrastructure, Allerton operates under the regulatory oversight of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC) for reliability standards. The 138 kV voltage level is common for regional power distribution, connecting higher-voltage transmission lines to lower-voltage distribution networks. The substation plays a role in maintaining grid reliability for the surrounding area, supporting the delivery of electricity from generation sources to end users. Its operational status ensures continued service within the We Energies network, which serves parts of Wisconsin and Michigan.

The substation is located in an urban or suburban setting near Milwaukee, Wisconsin, where electrical infrastructure is critical for supporting residential and commercial demand. The 138 kV voltage level indicates a medium-scale facility that contributes to grid stability in a region with seasonal temperature extremes, which can affect load patterns and infrastructure stress.
