Center Hill Substation - Operational 115 kV Electrical Substation in the United States

Center Hill Substation is an operational electrical substation located in the United States, with coordinates 33.778685, -84.473987. The facility operates at a voltage of 115 kV, classifying it as a medium-voltage substation that serves as a critical node in the local power transmission network. As a substation operating under U.S. jurisdiction, Center Hill Substation is subject to NERC reliability standards and FERC regulations for transmission-level assets. The 115 kV voltage level is typical for sub-transmission or distribution substations that connect bulk power systems to local distribution networks. Such facilities often employ switchgear and transformers compliant with IEEE standards. The substation's location near Atlanta, Georgia, places it in a region with growing electricity demand driven by urban and industrial expansion. Its operational status ensures continued support for grid reliability and power delivery to surrounding communities, contributing to the resilience of the regional electrical infrastructure.

The substation is situated in an urbanized area of Georgia, where electrical infrastructure must balance reliability with environmental considerations such as electromagnetic field management and stormwater runoff from impervious surfaces. The 115 kV voltage level requires appropriate clearance and safety buffers, and the facility's design likely incorporates measures to minimize visual impact and noise from transformers.
