Sidney Term Substation - 138 kV Electrical Infrastructure in the United States

Sidney Term is an operational electrical substation located in the United States, with coordinates 43.124846, -87.944480. As a substation, it is a critical node in the electrical infrastructure, facilitating voltage transformation and power distribution. The facility operates at 138 kV, a common transmission voltage level in the US, indicating its role in the high-voltage grid. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for transmission assets. In the United States, substations like Sidney Term are essential for maintaining grid stability and ensuring the efficient transfer of electricity from generation sources to load centers. The 138 kV voltage level suggests it serves as a sub-transmission or distribution substation, likely supplying power to local utilities or industrial customers. Environmentally, the substation's location in an urban or suburban area (near Milwaukee, Wisconsin) means it supports dense population and economic activity. Its operational status ensures reliable electricity supply, reducing the risk of outages that could impact communities and businesses. The facility's age and specific equipment are not detailed, but typical substations of this voltage class are designed for long-term service with regular maintenance to mitigate environmental risks such as oil leaks from transformers.

The substation is located in a region with a temperate climate, where seasonal weather variations can affect grid operations. Its urban setting implies proximity to residential and commercial areas, necessitating careful management of electromagnetic fields and noise. The 138 kV voltage level is typical for sub-transmission, balancing efficiency and safety. The facility's operational status indicates it is actively managed to prevent environmental incidents, such as transformer oil spills, which are regulated under US environmental laws.
