Overview
Onalaska Substation is an operational electrical substation in Texas, United States, owned and operated by Sam Houston Electric Cooperative. It operates at a voltage of 138 kV, serving the local grid.
Onalaska Substation is an operational electrical substation located in Texas, United States. Owned and operated by Sam Houston Electric Cooperative, the facility plays a key role in the regional power distribution network. With a voltage level of 138 kV, it is classified as a medium-voltage substation, typical for rural cooperative systems in the United States. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which set reliability standards for the bulk power system. As part of a cooperative, it adheres to standards for grid stability and safety. The 138 kV voltage level is common for subtransmission systems, connecting higher-voltage transmission lines to local distribution networks. Environmentally, the substation is situated in a rural area of Texas, where it supports agricultural and residential communities. Its role in the grid ensures reliable electricity supply, contributing to the region's economic activities. The facility's age and specific equipment are not detailed, but typical substations of this type are designed for long-term operation with regular maintenance.
Environmental context
The substation is located in a rural area of Texas, characterized by agricultural land and scattered residential developments. The 138 kV voltage level indicates it serves as a subtransmission node, connecting the bulk power system to local distribution networks. Its operation supports the region's energy needs without significant direct environmental impact, though typical considerations include electromagnetic fields and land use for infrastructure.
