Overview
Smithton Substation is an operational electrical substation in the United States, operating at 138 kV. It plays a role in regional grid stability and power distribution.
Smithton Substation is an operational electrical substation located in the United States, with coordinates 40.1715, -79.7272. The facility operates at a voltage of 138 kV, placing it in the medium-to-high voltage range typical for sub-transmission and distribution substations. As part of the U.S. electrical infrastructure, it supports the reliable delivery of electricity to local communities and industries. 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. The 138 kV voltage level is common for regional transmission networks, connecting higher-voltage transmission lines to lower-voltage distribution systems. The facility's design likely includes switchgear, transformers, and protection systems compliant with IEEE and NERC standards. Smithton Substation contributes to the resilience of the local power grid, serving as a critical node for electricity distribution in the region. Its operational status ensures continued support for residential, commercial, and industrial customers. The substation's location in the United States underscores its role within one of the world's largest and most complex electrical grids, where reliability and security are paramount.
Environmental context
The substation is situated in a region with a temperate climate, where seasonal weather variations can impact grid operations. The 138 kV voltage level indicates a balance between transmission efficiency and local distribution needs. The facility's location in a rural or suburban area may reduce direct environmental impacts, but its role in grid stability is critical for supporting renewable energy integration and load balancing.
Frequently asked questions
Smithton Substation is located in the United States at coordinates 40.1715, -79.7272.
Smithton Substation operates at a voltage of 138 kV, which is typical for sub-transmission and distribution substations in the United States.
Smithton Substation operates under the regulatory oversight of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for the U.S. bulk power system.
A 138 kV substation serves as an intermediate node in the power grid, stepping down voltage from higher transmission lines (e.g., 230 kV or 345 kV) for distribution to local networks, or stepping up voltage from generation sources.
Substations in the United States must comply with NERC reliability standards, FERC regulations, and IEEE standards such as IEEE C37 for switchgear and IEEE 80 for grounding.
