Leona Substation - Operational Substation in Texas, United States

Leona Substation is an operational electrical substation located in Texas, United States, owned and operated by South Texas Electric Cooperative. The facility operates at a voltage of 69 kV, placing it in the medium-voltage range typical for distribution-level substations serving rural and suburban areas. As a substation in the United States, Leona Substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC) for reliability standards. The facility's voltage level and role in the local grid are consistent with typical distribution substations that step down transmission voltages for local distribution. The substation plays a key role in the electrical infrastructure of the region, supporting the South Texas Electric Cooperative's mission to provide reliable power to its member-owners. Its location in Texas, a state with a large and growing energy demand, underscores its importance in maintaining grid stability and serving the local community.

The substation is located in a rural area of Texas, where electrical infrastructure is critical for supporting agricultural and residential loads. The 69 kV voltage level indicates a distribution role, with potential environmental considerations including land use for transmission corridors and electromagnetic field management. Typical substations in this region are subject to NERC reliability standards to ensure safe operation.
