Overview
Orange Grove Substation is an operational electrical substation in Texas, United States, owned and operated by South Texas Electric Cooperative. It operates at 69 kV, serving the regional grid.
Orange Grove Substation is an operational electrical substation located in Texas, United States. Owned and operated by South Texas Electric Cooperative, it plays a role in the regional power distribution network. The facility operates at a voltage level of 69 kV, which is typical for sub-transmission and distribution substations in rural and suburban areas. 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 the Electric Reliability Council of Texas (ERCOT) interconnection, it adheres to specific regional grid requirements. The 69 kV voltage level indicates a medium-scale substation that steps down power from higher transmission voltages for local distribution. Orange Grove Substation supports the electrical infrastructure of the surrounding community in southern Texas. Its operational status ensures reliable power delivery to residential, commercial, and agricultural customers in the area. The facility's role in the grid contributes to the stability and resilience of the local power supply, particularly in a region prone to extreme weather events.
Environmental context
The substation is located in a rural area of southern Texas, characterized by a mix of agricultural land and small communities. The local environment is semi-arid with hot summers and mild winters. Substations at this voltage level typically have a small physical footprint and minimal direct environmental impact, though they are critical for integrating renewable energy sources like wind and solar, which are prevalent in the region.
Frequently asked questions
