Overview
Dobbyville Substation is an operational electrical substation in Texas, United States, operated by Pedernales Electric Cooperative. It operates at 138 kV, serving the local grid.
Dobbyville Substation is an operational electrical substation located in Texas, United States. It is owned and operated by Pedernales Electric Cooperative, a major electric utility in the region. The substation operates at a voltage of 138 kV, which is typical for sub-transmission and distribution-level infrastructure in the United States. The facility 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 a 138 kV substation, it plays a role in stepping down voltage from higher transmission lines to distribution levels for local communities. The infrastructure likely includes switchgear, transformers, and protection systems compliant with industry standards such as IEEE C37. Dobbyville Substation contributes to the reliability of the electric grid in central Texas, an area with growing population and energy demand. Its location in a rural setting underscores its importance for serving dispersed communities. The substation's operational status ensures continued support for residential, commercial, and agricultural customers in the Pedernales Electric Cooperative service territory.
Environmental context
The substation is located in a rural area of central Texas, characterized by a mix of grasslands and agricultural land. The 138 kV voltage level indicates it is a medium-voltage facility, typically associated with lower environmental footprint compared to high-voltage transmission lines. The site's rural location reduces potential impacts on dense urban populations, though it may still require vegetation management and wildlife protection measures. The surrounding ecosystem includes habitats for local species, and the substation's operation adheres to environmental regulations to minimize disruption.
