Overview
Speedway Substation is an operational electrical substation owned by Entergy in the United States. It operates at 138 kV, serving grid stability and power distribution needs.
Speedway Substation is an operational electrical substation located in the United States, owned and operated by Entergy. The facility operates at a voltage of 138 kV, classifying it as a medium-voltage substation typical for regional power distribution and grid interconnection. As part of the Entergy system, this substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These standards ensure reliability and security for the bulk power system. The 138 kV voltage level is common for subtransmission networks, connecting high-voltage transmission lines to lower-voltage distribution systems. The substation plays a critical role in maintaining grid stability and delivering electricity to surrounding communities. Its operational status and location within Entergy's service territory support the regional power infrastructure, contributing to reliable energy supply for residential, commercial, and industrial customers.
Environmental context
The substation is located in a region with a humid subtropical climate, which can affect equipment performance and maintenance schedules. Its rural setting reduces immediate environmental impact compared to urban substations, but the facility must manage vegetation and wildlife interactions to prevent outages. The 138 kV voltage level indicates moderate electromagnetic field exposure, which is managed through standard siting and shielding practices.
