Overview
North Ooltewah Substation is an operational electrical substation in Tennessee, United States, operating at 161 kV and serving the local grid.
North Ooltewah Substation is an operational electrical substation located in Tennessee, United States. It operates at a voltage of 161 kV, placing it in the medium-to-high voltage range typical for sub-transmission and distribution substations that support regional grid stability. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for the bulk power system. As a 161 kV facility, it likely plays a role in stepping down power from higher-voltage transmission lines to serve local distribution networks, a common configuration in the U.S. electrical infrastructure. Located in a suburban area near Ooltewah, Tennessee, the substation supports the growing residential and commercial demand in the region. Its operational status ensures continued reliability for the local community, contributing to the resilience of the broader Tennessee Valley Authority (TVA) grid, which serves the southeastern United States.
Environmental context
The substation is situated in a mixed urban-rural environment in southeastern Tennessee, an area with moderate population density and a mix of residential and agricultural land use. The 161 kV voltage level indicates it is a critical node for local power distribution, with potential environmental considerations including electromagnetic field management and stormwater runoff from the substation yard. The facility's design likely incorporates standard mitigation measures for noise and visual impact, common for substations in suburban settings.
Frequently asked questions
North Ooltewah Substation is located in Tennessee, United States, near the community of Ooltewah. Its approximate coordinates are 35.120943° N, -85.046835° W.
North Ooltewah Substation operates at a voltage of 161 kV, which is a common sub-transmission voltage level used for distributing power from high-voltage transmission lines to local distribution networks.
The operator of North Ooltewah Substation is not publicly listed, but it is likely owned and operated by a local utility such as the Tennessee Valley Authority (TVA) or a regional electric cooperative, consistent with typical substation ownership in the area.
Substations in the United States must comply with NERC reliability standards for grid stability and FERC regulations for interstate electricity transmission. Additionally, substations often follow IEEE and ANSI standards for equipment and safety.
A 161 kV substation typically serves as a sub-transmission node, stepping down voltage from higher transmission levels (e.g., 230 kV or 500 kV) to distribution levels (e.g., 69 kV or lower) for delivery to residential, commercial, and industrial customers.
