Overview
Coldwater Substation is an operational electrical substation in Tennessee, United States, owned and operated by the Tennessee Valley Authority (TVA) with a voltage level of 69 kV.
Coldwater Substation is an operational electrical substation located in Tennessee, United States. It is owned and operated by the Tennessee Valley Authority (TVA), a major federal utility that manages the electric power system across the Tennessee Valley region. The substation operates at a voltage of 69 kV, which is typical for sub-transmission and distribution-level infrastructure supporting local grid stability. As part of TVA's extensive network, Coldwater Substation adheres to North American Electric Reliability Corporation (NERC) reliability standards and Federal Energy Regulatory Commission (FERC) regulations. These frameworks ensure the substation's equipment, including switchgear and transformers, meets stringent performance and safety criteria. The 69 kV voltage level places it in a medium-voltage category, often serving as a link between higher-voltage transmission lines and lower-voltage distribution networks. The substation plays a critical role in delivering electricity to surrounding communities and industries in rural Tennessee. Its operational status contributes to the resilience of the regional grid, supporting TVA's mission to provide reliable and affordable power. The facility's location in a rural area underscores its importance in maintaining electrical service continuity for agricultural and residential customers.
Environmental context
The substation is situated in a rural area of Tennessee, where the local environment includes agricultural lands and forested regions. Electrical infrastructure like this substation is designed to minimize environmental impact through proper siting and equipment shielding. The 69 kV voltage level indicates moderate electromagnetic fields, which are managed within regulatory limits to protect nearby ecosystems and human health.
