Ashley Substation: 138 kV Electrical Infrastructure in the United States

Ashley is an operational electrical substation located in the United States, with coordinates 38.332820, -89.190886. The facility operates at a voltage of 138 kV, classifying it as a high-voltage substation critical for transmission and distribution within the regional power grid. As part of the U.S. electrical infrastructure, it supports reliable electricity delivery to surrounding communities. 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 bulk power systems. At 138 kV, Ashley is typical of sub-transmission or transmission-level substations that step down voltage for local distribution or interconnect with other grid assets. The facility's location in a rural area of Illinois suggests it may serve agricultural or small urban loads. Environmentally, the substation's operation involves electromagnetic fields and potential impacts on local wildlife, though modern design minimizes these effects. Its role in grid stability is significant, as it helps balance supply and demand, integrate renewable energy sources, and maintain voltage levels within safe limits. The facility contributes to the resilience of the U.S. electrical grid, supporting economic activity and community services in the region.

The substation is located in a rural area of Illinois, where agricultural land and small communities dominate. Its 138 kV operation generates electromagnetic fields, but standard mitigation measures are in place. The facility's presence supports grid reliability and renewable energy integration, with minimal direct environmental footprint beyond land use and visual impact.
