Castleberry Substation - Alabama Electrical Substation Operated by PowerSouth Energy Cooperative

Castleberry Substation is an electrical substation located in Alabama, United States, owned and operated by PowerSouth Energy Cooperative. The facility is operational and plays a role in the regional transmission network, stepping down voltage for distribution to local communities. The substation operates at 115 kV, a common voltage level for subtransmission systems in the United States. As part of the PowerSouth Energy Cooperative network, it is subject to NERC reliability standards and FERC regulations for transmission-level assets. The facility likely includes switchgear, transformers, and protection systems compliant with industry standards. This substation supports grid stability in the region by facilitating power flow from generation sources to end users. Its location in rural Alabama underscores its importance in serving cooperative members and maintaining reliable electricity supply. The facility's age and specific equipment details are not disclosed, but its operational status indicates ongoing maintenance and compliance with regulatory requirements.

The substation is situated in a rural area of Alabama, where the local environment includes mixed forest and agricultural land. Electrical infrastructure in such settings typically requires vegetation management to prevent outages and minimize fire risk. The 115 kV voltage level indicates moderate environmental footprint, with potential electromagnetic field considerations near residential areas. PowerSouth Energy Cooperative likely follows environmental best practices for substation operations.
