Tordillo Substation is an operational electrical substation located in Texas, United States, owned and operated by South Texas Electric Cooperative. The facility plays a key role in the regional power transmission and distribution network, stepping down high-voltage electricity for local distribution. The substation operates at voltage levels of 138 kV and 69 kV, which are typical for sub-transmission and distribution applications in the United States. As part of the South Texas Electric Cooperative's infrastructure, it supports the delivery of electricity to member cooperatives and rural communities. The facility adheres to North American Electric Reliability Corporation (NERC) reliability standards and is subject to Federal Energy Regulatory Commission (FERC) oversight for transmission-level assets. Located in a rural area of south-central Texas, the substation contributes to grid stability and energy access for the region. Its operational status ensures continued service to the cooperative's members, supporting agricultural, residential, and commercial loads. The facility's design and maintenance align with industry standards for substation automation and safety.
Environmental context
The substation is situated in a rural area of south-central Texas, characterized by agricultural land and scattered communities. The local environment is semi-arid with hot summers and mild winters, which influences equipment cooling and vegetation management around the site. The facility's voltage levels and rural location reduce its environmental footprint compared to urban substations, but it still requires careful maintenance to prevent wildfires and manage wildlife interactions.
