Overview
Tazewell is an operational electrical substation in Illinois, United States, owned and operated by Ameren. It handles voltages of 345 kV, 138 kV, and 69 kV, serving as a key node in the regional transmission grid.
Tazewell is an electrical substation located in Illinois, United States, and is part of the Ameren transmission network. The facility is operational and handles multiple voltage levels including 345 kV, 138 kV, and 69 kV, indicating its role in both high-voltage transmission and sub-transmission distribution. As a substation operating under the jurisdiction of the United States, Tazewell is subject to NERC reliability standards and FERC regulation for transmission-level assets. The 345 kV voltage class is typical for bulk power transmission, connecting generation sources to major load centers. The inclusion of 138 kV and 69 kV suggests the substation also serves regional distribution networks. The substation's location in central Illinois places it within a region with a mix of urban and agricultural loads. Its role in the Ameren grid contributes to the stability and reliability of electricity supply for surrounding communities and industrial customers. The facility's operational status ensures continued support for the local electrical infrastructure.
Environmental context
The substation is situated in a rural area of central Illinois, characterized by agricultural land and scattered residential developments. The surrounding environment is relatively flat, with typical Midwestern climate patterns. The facility's operation involves electromagnetic fields and potential oil spill risks from transformers, but standard mitigation measures are in place. The substation's location away from densely populated areas reduces direct human exposure to these factors.
