Fort Hill Substation - Operational 138 kV Substation in the United States

Fort Hill Substation is an operational electrical substation located in the United States, with coordinates 41.748053, -88.195469. It operates at a voltage of 138 kV, which classifies it as a high-voltage substation critical for regional power transmission and distribution. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), ensuring grid reliability and compliance with mandatory standards. As a 138 kV facility, it plays a key role in stepping down transmission voltages for local distribution or interconnecting generation sources. Fort Hill Substation contributes to the stability of the electrical grid in its region, supporting residential, commercial, and industrial loads. Its operational status ensures continued service to the community, and its location in the United States places it within one of the world's largest and most complex electrical infrastructure networks.

The substation is located in an urban or suburban area near Chicago, Illinois, where electrical infrastructure is dense and critical for supporting a large population and industrial base. The 138 kV voltage level indicates it is part of the sub-transmission network, which balances reliability and environmental footprint by minimizing land use while serving high demand. Local environmental considerations include electromagnetic field management and stormwater runoff control, typical for substations in developed regions.
