Overview
Summerfield Substation is an operational electrical substation in the United States, operated by Sequachee Valley Electric Cooperative. It operates at a voltage of 46 kV, serving the local grid.
Summerfield Substation is an operational electrical substation located in the United States, managed by Sequachee Valley Electric Cooperative. The substation operates at a voltage level of 46 kV, classifying it as a medium-voltage distribution substation that plays a role in local power distribution. As a substation within the U.S. electrical grid, it operates under 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 46 kV voltage level is typical for sub-transmission or distribution substations that step down power from higher transmission voltages for local distribution. The substation's location in Tennessee places it within the service territory of Sequachee Valley Electric Cooperative, a member-owned utility serving rural and suburban areas. Its operational status indicates it is actively contributing to the regional electrical infrastructure, supporting residential, commercial, and industrial customers in the area.
Environmental context
The substation is situated in a rural area near the Cumberland Plateau, characterized by forested terrain and moderate climate. Its operation involves minimal direct environmental impact, primarily related to electromagnetic fields and potential vegetation management. The surrounding ecosystem includes mixed hardwood forests and wildlife habitats, but the substation's footprint is small relative to the landscape.
