Hillman Highway Substation is an operational electrical substation located in the United States, owned and operated by Appalachian Power Company. As a substation, it plays a critical role in the regional electrical grid by stepping down transmission voltages for local distribution. The substation operates at multiple voltage levels: 69 kV (transmission), 13.09 kV, and 12.47 kV (distribution). This configuration is typical for a medium-voltage substation that serves both industrial and residential loads. The facility is part of the Appalachian Power network, which is regulated by the Federal Energy Regulatory Commission (FERC) and adheres to North American Electric Reliability Corporation (NERC) reliability standards for grid stability. As part of the Appalachian Power grid, this substation supports electricity delivery to communities in the region. Its operational status ensures continued service to local customers, contributing to the reliability of the broader electrical infrastructure in the United States.
Environmental context
The substation is located in a region with a temperate climate, where seasonal weather variations can impact grid operations. Its voltage levels and urban-rural setting influence its environmental footprint, with typical considerations including electromagnetic field management and vegetation clearance for line safety. The facility operates under standard environmental regulations for electrical infrastructure.
