Overview
Seward Junction Substation is an operational electrical substation in Texas, United States, owned and operated by Pedernales Electric Cooperative. It operates at 138 kV, serving the local grid.
Seward Junction Substation is an operational electrical substation located in Texas, United States. Owned and operated by Pedernales Electric Cooperative, it plays a key role in the regional power distribution network. The substation operates at a voltage of 138 kV, which is typical for sub-transmission and distribution-level infrastructure in the United States. As a substation under the jurisdiction of the United States, it operates within the regulatory framework established by the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These standards ensure grid reliability and security. The 138 kV voltage level places it in the medium-to-high voltage range, commonly used to distribute power from transmission systems to local distribution networks. The substation supports the electrical infrastructure of the surrounding community, contributing to grid stability and power delivery. Its location in Texas, a state with a large and diverse energy mix, underscores its importance in maintaining reliable electricity supply. The facility is part of Pedernales Electric Cooperative's network, which serves a wide area in central Texas.
Environmental context
The substation is situated in a region of Texas characterized by a mix of urban and rural areas. Its operation involves standard electrical infrastructure considerations such as electromagnetic fields and noise, which are managed through typical industry practices. The facility's location does not appear to be in an environmentally sensitive area, and its impact is limited to the immediate vicinity of the substation.
