Mill Creek Substation: 138 kV Electrical Substation in the United States

Mill Creek Substation is an operational electrical substation located in the United States, specifically at coordinates 30.994276, -94.106046. Operated by JNEC, this facility is part of the country's extensive electrical infrastructure network, handling high-voltage transmission. The substation operates at a voltage of 138 kV, which is typical for sub-transmission or distribution-level assets in the US grid. As a substation, it plays a critical role in stepping down voltage from higher transmission lines to lower distribution levels, ensuring reliable electricity supply to surrounding areas. The facility is subject to NERC reliability standards and FERC regulations, which govern the operation and maintenance of such assets to maintain grid stability. Mill Creek Substation contributes to the resilience of the local electrical grid by facilitating power distribution and voltage regulation. Its location in a rural area of Texas underscores its importance in connecting remote generation sources to load centers. The substation's operational status indicates it is actively serving the community, supporting both residential and industrial electricity needs.

The substation is situated in a rural area of Texas, characterized by forested landscapes and proximity to the Sabine River. Its operation involves managing high-voltage equipment, which requires careful environmental planning to minimize impacts on local ecosystems. The facility's design likely incorporates measures to prevent oil leaks from transformers and to manage electromagnetic fields, aligning with standard environmental practices for electrical infrastructure in the US.
