Overview
Coahoma Substation is an operational electrical substation in Texas, United States, owned and operated by Oncor. It handles voltages of 69 kV, 24.94 kV, and 12.47 kV, serving the local grid.
Coahoma Substation is an operational electrical substation located in Texas, United States. Owned and operated by Oncor, a major transmission and distribution utility in the state, the facility plays a key role in the regional electrical infrastructure. The substation handles multiple voltage levels, including 69 kV, 24.94 kV, and 12.47 kV, indicating its function in stepping down transmission-level power for distribution. As part of the US electrical grid, Coahoma Substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). Oncor, as a transmission service provider, must comply with NERC reliability standards to ensure grid stability. The substation's voltage levels suggest it serves both sub-transmission and distribution functions, typical for facilities in rural or semi-urban areas of Texas. The substation's location in Texas places it within the Electric Reliability Council of Texas (ERCOT) interconnection, which manages the state's power grid. Coahoma Substation contributes to the reliability of local electricity supply, supporting residential, commercial, and industrial customers in the region. Its operational status and integration with Oncor's network underscore its importance in maintaining grid stability and meeting energy demands.
Environmental context
Coahoma Substation is situated in a semi-arid region of Texas, characterized by low rainfall and high temperatures. The facility's electrical infrastructure is designed to withstand local climate conditions, including heat and occasional dust storms. As a substation, its environmental impact is primarily related to land use and electromagnetic fields, which are managed through standard siting and operational practices. The surrounding area is sparsely populated, reducing potential conflicts with sensitive ecosystems.
