Jacks Creek Substation: Operational Substation in Tennessee, United States

Jacks Creek Substation is an operational electrical substation located in Tennessee, United States. Owned by Southwest Tennessee Electric Membership Corporation, the facility serves as a key node in the local power distribution network, stepping down transmission-level voltage for distribution to residential and commercial customers. The substation operates at dual voltage levels of 161,000 volts (161 kV) for transmission and 12,470 volts (12.47 kV) for distribution, a common configuration for substations serving rural and suburban areas. As part of the U.S. electrical infrastructure, it adheres to NERC reliability standards and FERC regulations for grid stability and safety. The facility's location in rural Tennessee reflects the typical scale of substations operated by electric membership cooperatives. This substation plays a critical role in ensuring reliable electricity supply to the surrounding community. By transforming high-voltage power from transmission lines to lower voltages suitable for local distribution, it supports economic activity and daily life in the region. Its operation under Southwest Tennessee Electric Membership Corporation underscores the cooperative model prevalent in rural electrification across the United States.

The substation is situated in a rural area of Tennessee, characterized by mixed forest and agricultural land. Its operation involves electromagnetic fields and potential oil leakage from transformers, which are managed through standard environmental safeguards. The site's location away from dense urban centers reduces direct population exposure, but proximity to natural habitats requires adherence to environmental regulations to minimize ecological impact.
