Overview
North Main Substation is an operational electrical substation in the United States, operating at 138 kV. It plays a key role in regional grid stability and power distribution.
North Main Substation is an operational electrical substation located in the United States, with coordinates 32.762065, -97.335733. The facility operates at a voltage of 138 kV, classifying it as a high-voltage substation critical for transmission and distribution networks. As part of the U.S. electrical infrastructure, it supports grid reliability and power delivery to surrounding areas. 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 transmission-level assets. The 138 kV voltage level is typical for subtransmission systems, connecting bulk power sources to distribution networks. The facility's location in an urban area suggests it serves a dense load center, requiring robust automation and protection systems compliant with ISO/IEC 61850 standards. Environmentally, the substation's urban setting minimizes land-use impacts but requires careful management of electromagnetic fields and noise. Its role in grid stability is significant, as it likely interconnects with other substations and power plants to ensure reliable electricity supply. The facility's operational status and voltage level indicate it is a medium-to-large scale asset within the U.S. electrical grid.
Environmental context
The substation is located in an urban area, which reduces direct ecological disruption but necessitates compliance with local noise and electromagnetic field regulations. Its 138 kV operation contributes to grid efficiency, potentially reducing transmission losses compared to lower voltage lines. The facility's presence supports electrification and renewable energy integration, aligning with broader environmental goals of reducing carbon emissions through reliable power delivery.
Frequently asked questions
North Main Substation is located in the United States at coordinates 32.762065, -97.335733, likely in an urban area of Texas based on the coordinates.
North Main Substation operates at 138 kV, a common subtransmission voltage level used to connect bulk power sources to distribution networks.
A 138 kV substation steps down high-voltage transmission power for distribution to industrial, commercial, and residential customers, ensuring grid stability and reliable electricity supply.
As a U.S. electrical substation, it must comply with NERC reliability standards and FERC regulations for transmission assets, as well as ISO/IEC 61850 for substation automation.
By operating at 138 kV, it helps balance load and supply, supports voltage regulation, and provides redundancy in the transmission network, reducing the risk of outages.
