Overview
Greensburg Substation is an operational electrical substation in Kentucky, United States, owned and operated by East Kentucky Power Cooperative, Inc. It operates at 161 kV, serving the regional grid.
Greensburg Substation is an operational electrical substation located in Kentucky, United States. Owned and operated by East Kentucky Power Cooperative, Inc., it plays a key role in the regional transmission network. The substation operates at a voltage of 161 kV, which is typical for sub-transmission and distribution-level infrastructure in the United States. As part of the U.S. electrical grid, Greensburg Substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These bodies enforce reliability standards for bulk power systems, ensuring stable and secure electricity delivery. The substation likely employs standard automation and protection systems, such as those based on IEC 61850, to manage power flow and maintain grid stability. The substation serves the local community and industrial base in the Greensburg area, contributing to the reliability of electricity supply for residential, commercial, and agricultural users. Its location in rural Kentucky underscores its importance in connecting distributed generation and load centers to the broader grid. The facility's operational status and ownership by a cooperative highlight its role in member-owned, community-focused power distribution.
Environmental context
The substation is situated in a rural area of Kentucky, where the landscape is characterized by rolling hills and agricultural land. The local environment is influenced by temperate climate conditions, with seasonal variations affecting electricity demand. The substation's 161 kV voltage level indicates it is part of the sub-transmission system, which typically has lower environmental impact than high-voltage transmission lines. However, its operation involves electromagnetic fields and potential impacts on local wildlife, mitigated through standard siting and maintenance practices.
