Overview
Calera Substation is an operational electrical substation in Alabama, United States, owned and operated by Alabama Power. It handles voltages of 115 kV and 46 kV, serving the local grid.
Calera Substation is an electrical substation located in Alabama, United States, owned and operated by Alabama Power, a subsidiary of Southern Company. The facility is operational and plays a role in the regional transmission and distribution network, handling voltages of 115 kV and 46 kV, which are typical for sub-transmission and distribution levels. As part of the U.S. electrical infrastructure, Calera Substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) reliability standards and the Federal Energy Regulatory Commission (FERC) for interstate transmission. The substation's voltage levels indicate it serves as a distribution substation, stepping down power from higher transmission voltages to supply local industrial, commercial, and residential customers in the Calera area. The substation's location in central Alabama places it within the service territory of Alabama Power, which provides electricity to over 1.4 million customers. The facility contributes to grid stability and reliability in the region, supporting the growing energy demands of the community and surrounding areas. Its operational status ensures continued power delivery to end-users.
Environmental context
The substation is situated in a region with a humid subtropical climate, which can affect equipment performance and maintenance needs. The surrounding area includes a mix of urban and rural land uses, with potential environmental considerations such as stormwater runoff and electromagnetic field management. The facility's design likely incorporates standard environmental safeguards for oil containment and noise reduction to minimize local impact.
