Overview
AEP Marion Substation is an operational electrical substation in the United States, owned and operated by American Electric Power. It operates at a voltage of 69 kV, serving the local grid.
AEP Marion Substation is an electrical substation located in the United States, owned and operated by American Electric Power (AEP). The facility is operational and plays a role in the regional power transmission and distribution network. As a substation, it steps down high-voltage electricity for local distribution or interconnects transmission lines. The substation operates at a voltage of 69 kV, which is a common sub-transmission voltage level in the United States. This voltage level typically serves industrial customers or feeds into lower-voltage distribution networks. The facility is part of AEP's extensive grid infrastructure, which spans multiple states and is regulated by the Federal Energy Regulatory Commission (FERC) for wholesale electricity markets and reliability standards set by the North American Electric Reliability Corporation (NERC). The substation's location in Indiana contributes to the reliability of the local power grid, supporting residential, commercial, and industrial electricity needs. As part of AEP's system, it helps maintain grid stability and facilitates the integration of generation resources. The facility's operational status ensures continued service to the surrounding community.
Environmental context
The substation is located in a rural area of Indiana, where the surrounding landscape is primarily agricultural. Electrical substations like this one have a localized environmental footprint, including electromagnetic fields and potential impacts on land use. The 69 kV voltage level indicates a sub-transmission facility, which typically has lower visual and ecological impacts compared to high-voltage transmission lines. The site's operation is subject to environmental regulations that manage stormwater runoff and equipment maintenance to minimize soil and water contamination.
Frequently asked questions
AEP Marion Substation is located in the United States, specifically in the state of Indiana, near the city of Marion. Its coordinates are approximately 40.56° N, -85.66° W.
AEP Marion Substation operates at a voltage of 69 kV (69,000 volts), which is a sub-transmission voltage level commonly used to distribute power to industrial areas or feed into lower-voltage distribution networks.
AEP Marion Substation is owned and operated by American Electric Power (AEP), one of the largest electric utilities in the United States, serving millions of customers across multiple states.
In the United States, substations are subject to reliability standards set by the North American Electric Reliability Corporation (NERC) and regulated by the Federal Energy Regulatory Commission (FERC) for wholesale electricity markets. Additionally, local and state regulations govern safety and environmental compliance.
A 69 kV substation typically serves as a sub-transmission facility that steps down higher transmission voltages (e.g., 138 kV or 230 kV) for distribution to industrial customers or further step-down to primary distribution voltages (e.g., 12 kV or 34.5 kV). It plays a critical role in maintaining grid reliability and delivering electricity to end users.
