Overview
Wallace Lake Substation is an operational electrical substation in Louisiana, United States, owned and operated by Southwestern Electric Power Company. It operates at a voltage of 138 kV, serving the regional grid.
Wallace Lake Substation is an electrical substation located in Louisiana, United States, and is owned and operated by Southwestern Electric Power Company (SWEPCO). The facility is operational and plays a role in the regional transmission network, operating at a voltage level of 138 kV, which is typical for sub-transmission and distribution substations in the United States. As part of SWEPCO's infrastructure, the substation is subject to regulatory oversight by the Federal Energy Regulatory Commission (FERC) and must comply with North American Electric Reliability Corporation (NERC) reliability standards. The 138 kV voltage level indicates that this substation likely serves as a step-down point from higher transmission voltages to distribution levels, supporting local load centers. The substation's location in Louisiana places it within the Southwest Power Pool (SPP) regional transmission organization, which coordinates grid reliability and wholesale electricity markets. The facility contributes to the stability and resilience of the local power grid, serving residential, commercial, and industrial customers in the area.
Environmental context
The substation is situated in a region characterized by a humid subtropical climate, with hot summers and mild winters. The area is prone to thunderstorms and hurricanes, which can pose risks to electrical infrastructure. The substation's design likely includes measures to withstand severe weather, such as elevated equipment and robust grounding systems. Its location near Wallace Lake may require attention to local hydrology and flood risk management.
