Overview
Morrison Substation is an operational electrical substation in Tennessee, United States, owned and operated by the Tennessee Valley Authority (TVA) at a voltage level of 161 kV.
Morrison 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 high-voltage transmission category, which is typical for TVA's extensive grid infrastructure. As part of the TVA system, Morrison Substation is subject to North American Electric Reliability Corporation (NERC) reliability standards and Federal Energy Regulatory Commission (FERC) regulation for transmission-level assets. The 161 kV voltage level indicates its role in bulk power transmission, connecting generation sources to distribution networks. TVA's substations are critical for maintaining grid stability across the Tennessee Valley region. The substation's location in rural Tennessee supports the local grid by stepping down transmission voltages for distribution to residential and industrial customers. Its operational status ensures continued reliability for the surrounding area. TVA's integrated resource planning and maintenance programs help mitigate risks associated with aging infrastructure and extreme weather events common in the region.
Environmental context
The substation is situated in a rural area of Tennessee, where the local environment includes mixed forest and agricultural land. The 161 kV voltage level and TVA's operational standards ensure minimal environmental footprint through proper maintenance and vegetation management. The substation's location away from urban centers reduces potential impacts on sensitive habitats, while its role in the grid supports regional energy reliability.
