Overview
Colonial Substation is an operational electrical substation in the United States, operating at 115 kV. It plays a role in regional grid stability and power distribution.
Colonial Substation is an operational electrical substation located in the United States, with coordinates 33.856403, -84.630128. The facility operates at a voltage of 115 kV, placing it in the medium-voltage range typical for distribution and sub-transmission networks. As a substation, it serves as a critical node for stepping down voltage and routing electricity to local grids. The substation operates under the regulatory framework of the United States, which includes NERC reliability standards for bulk power system and FERC oversight for interstate transmission. The 115 kV voltage level is common for regional transmission and distribution, and the facility likely includes switchgear, transformers, and protection systems compliant with IEEE standards. Its location near Atlanta, Georgia, suggests it supports a growing urban and suburban area with significant electricity demand. Environmentally, the substation's operation involves electromagnetic fields and potential oil containment from transformers, but modern designs include mitigation measures. The facility contributes to grid resilience by providing voltage regulation and load balancing. Its operational status ensures continued service to the surrounding community, supporting residential, commercial, and industrial users.
Environmental context
The substation is located in a region with a humid subtropical climate, which can affect equipment performance and maintenance schedules. The 115 kV voltage level indicates moderate electromagnetic field exposure, but standard setbacks and shielding are typically employed. The facility's urban-proximate location may require noise mitigation and visual screening to minimize community impact.
Frequently asked questions
