Herty North Switching Station - Oncor 138 kV Substation in Texas, USA

Herty North Switching Station is a substation located in Texas, United States, owned and operated by Oncor, a major transmission and distribution utility. The facility is operational and operates at a voltage of 138 kV, which is typical for sub-transmission and distribution-level infrastructure in the region. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for the bulk power system. Oncor, as the owner and operator, adheres to these standards to ensure grid stability and safety. The 138 kV voltage level places this facility in the medium-voltage range, commonly used for distributing power from transmission systems to local distribution networks. As part of Oncor's extensive network in Texas, Herty North Switching Station plays a critical role in maintaining reliable electricity supply to the surrounding area. Its location in East Texas supports the region's energy needs, including residential, commercial, and industrial consumers. The substation's operational status ensures continued grid connectivity and power flow management.

The substation is located in a rural area of East Texas, characterized by pine forests and a humid subtropical climate. The facility's 138 kV voltage level indicates it serves as a distribution hub, likely connecting to lower-voltage lines for local delivery. The surrounding environment includes mixed land use, with forestry and agriculture being prominent. Substations of this type typically have a small physical footprint and are designed to minimize visual and ecological impact, with vegetation management practices to maintain clearance and prevent outages.
