Overview
Laprairie is an operational electrical substation in the United States, operating at 138 kV. It plays a role in regional grid stability and power distribution.
Laprairie is an operational electrical substation located in the United States, with coordinates 42.605125, -88.962914. The facility operates at a voltage level of 138 kV, classifying it as a high-voltage substation that supports transmission and distribution networks. This voltage level is typical for sub-transmission systems that connect bulk power sources to local distribution grids. 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 138 kV facility, it is subject to NERC's Critical Infrastructure Protection (CIP) standards and must comply with reliability requirements for voltage regulation and grid stability. The substation likely employs modern switchgear and automation systems in line with industry practices. Laprairie substation serves as a key node in the local electrical infrastructure, facilitating the reliable delivery of electricity to surrounding communities and industries. Its operational status ensures continued support for grid resilience and energy supply. The facility's location in the United States places it within one of the world's largest interconnected power systems, where substations like Laprairie are essential for maintaining system balance and preventing outages.
Environmental context
The substation is situated in a region with a temperate climate, where seasonal temperature variations can affect electrical demand and grid operations. The facility's 138 kV voltage level indicates it is part of the sub-transmission network, which typically has lower environmental impact than extra-high-voltage lines but still requires careful siting to minimize land use and visual effects. Urban or rural location influences the ecological context; without specific data, the substation likely adheres to standard environmental mitigation practices for electromagnetic fields and stormwater management.
Frequently asked questions
