Lyssy Substation - 138 kV Electrical Substation in Texas, United States

Lyssy Substation is an operational electrical substation located in Texas, United States. Owned by South Texas Electric Cooperative, it plays a role in the regional transmission network. The facility operates at a voltage of 138 kV, which is typical for sub-transmission and distribution-level infrastructure in the United States. As a substation under the jurisdiction of the United States, it operates within the regulatory framework established by the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These standards ensure grid reliability and compliance with mandatory reliability standards. The 138 kV voltage level indicates that this substation likely serves as a critical node for distributing power to local communities or industrial customers. The substation is located in a rural area of south-central Texas, where the electrical infrastructure supports agricultural and residential loads. Its operation contributes to the stability of the local grid, and its ownership by a cooperative underscores its role in serving member-owners in the region. The facility's age and specific equipment details are not publicly available, but its operational status confirms ongoing grid connectivity.

The substation is situated in a rural area of Texas, where the local environment is characterized by semi-arid conditions and agricultural land use. Electrical infrastructure in such settings must be designed to withstand extreme weather events, including heatwaves and occasional winter storms, which can impact grid stability. The 138 kV voltage level suggests this facility is part of the sub-transmission network, balancing local load demands with regional power flows.
