Overview
Weakley Substation is an operational electrical substation in Tennessee, United States, owned and operated by the Tennessee Valley Authority. It operates at a voltage of 161 kV, supporting regional grid stability.
Weakley Substation is an operational electrical substation located in Tennessee, United States. Owned and operated by the Tennessee Valley Authority (TVA), it is a key node in the regional transmission network. The substation operates at a voltage of 161 kV, which is typical for sub-transmission and distribution-level infrastructure in the United States. As part of the TVA system, Weakley Substation adheres to North American Electric Reliability Corporation (NERC) reliability standards and is subject to Federal Energy Regulatory Commission (FERC) regulation for transmission-level assets. The substation likely employs modern automation and protection systems, including those based on the IEC 61850 standard, to ensure reliable operation and integration with the wider grid. The substation plays a critical role in delivering electricity to local communities and industries in the Weakley County area. Its operation supports grid stability and resilience, particularly in a region that experiences diverse weather conditions. The TVA's integrated resource planning ensures that substations like Weakley are maintained to meet growing demand and evolving regulatory requirements.
Environmental context
The substation is located in a rural area of Tennessee, where the surrounding landscape includes agricultural land and small communities. The 161 kV voltage level indicates it serves as a distribution hub, connecting local loads to the transmission grid. Environmental considerations for such infrastructure include minimizing electromagnetic field impacts and ensuring proper stormwater management to protect local waterways.
