Overview
Coryell County Substation is an operational electrical substation in Texas, USA, operated by Texas-New Mexico Power. It operates at 69 kV, supporting regional grid stability.
Coryell County Substation is an operational electrical substation located in Coryell County, Texas, United States. Owned and operated by Texas-New Mexico Power, this facility plays a role in the regional transmission and distribution network, serving local communities and industrial users. The substation operates at a voltage level of 69 kV, which is typical for sub-transmission and distribution substations in the United States. As part of the Texas Interconnection, the substation operates under the regulatory oversight of the Public Utility Commission of Texas (PUCT) and adheres to NERC reliability standards. The 69 kV voltage class is commonly used for distributing power from larger transmission lines to local distribution networks, making this substation a critical node for electricity delivery in the area. Texas-New Mexico Power, a subsidiary of PNM Resources, manages a portfolio of generation, transmission, and distribution assets across Texas and New Mexico. The substation's location in rural Coryell County supports agricultural, residential, and small commercial loads. Its operational status ensures continued reliability for the local grid, contributing to the overall stability of the Texas power system. The facility's age and specific equipment details are not publicly available, but its ongoing operation indicates compliance with current industry standards and maintenance practices.
Environmental context
The substation is situated in a rural area of central Texas, characterized by rolling hills and agricultural land. The local environment is subject to hot summers and occasional severe weather, including thunderstorms and tornadoes, which can impact grid infrastructure. The 69 kV voltage level and rural location suggest the substation serves a moderate load density, with potential environmental considerations related to land use and electromagnetic fields. Typical mitigation measures include vegetation management and adherence to NERC standards for physical and cyber security.
