Overview
Poseyville Substation is an operational electrical substation in Indiana, United States, owned and operated by Hoosier Energy. It operates at 69 kV, serving as a key node in the regional power grid.
Poseyville Substation is an operational electrical substation located in Indiana, United States. Owned and operated by Hoosier Energy, it functions as a critical component of the regional electrical infrastructure, stepping down transmission voltage for local distribution. The substation operates at a voltage of 69 kV, which is typical for sub-transmission or distribution-level facilities. Hoosier Energy is a generation and transmission cooperative serving member cooperatives in Indiana and Illinois. The facility adheres to North American Electric Reliability Corporation (NERC) reliability standards and is subject to Federal Energy Regulatory Commission (FERC) regulation for transmission-level assets. As part of the Hoosier Energy network, Poseyville Substation supports grid stability and electricity delivery to rural and suburban communities. Its location in southwestern Indiana places it within a region with a mix of agricultural and industrial load, contributing to the reliability of the local power supply.
Environmental context
The substation is situated in a rural area of southwestern Indiana, where the surrounding landscape is primarily agricultural. Electrical infrastructure in such settings typically requires careful siting to minimize impacts on farmland and natural habitats. The 69 kV voltage level indicates a sub-transmission role, with lower electromagnetic field exposure compared to higher-voltage lines. Standard mitigation measures include vegetation management and adherence to environmental regulations during construction and operation.
