Walter Anderson Substation - TVA Electrical Substation in Tennessee, United States

Walter Anderson Substation is an operational electrical substation located in Tennessee, United States. It is owned and operated by the Tennessee Valley Authority (TVA), a federally owned electric utility corporation. The substation operates at a voltage of 161 kV, placing it in the medium-to-high voltage range typical for transmission and distribution substations in the US grid. As part of TVA's extensive network, this substation likely plays a role in stepping down high-voltage electricity from transmission lines for local distribution or interconnecting with other grid assets. TVA's system is regulated by the Federal Energy Regulatory Commission (FERC) and adheres to North American Electric Reliability Corporation (NERC) reliability standards, ensuring grid stability and security. The substation's location in Tennessee supports the region's energy needs, serving residential, commercial, and industrial customers. TVA's integrated resource planning and environmental stewardship initiatives contribute to the operational significance of facilities like Walter Anderson Substation in maintaining reliable electricity supply.

The substation is situated in a region with a mix of urban and rural areas, and its operation is subject to environmental regulations under the National Environmental Policy Act (NEPA). TVA conducts environmental reviews for new projects and upgrades, considering impacts on local ecosystems, water resources, and air quality. The substation's voltage level and grid criticality influence its environmental footprint, with higher voltage facilities typically requiring more extensive mitigation measures.
