Overview
Charleston Park 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.
Charleston Park Substation is an operational electrical substation located in the United States. The facility operates at a voltage of 138 kV, which classifies it as a high-voltage substation typically used for subtransmission or distribution within the electrical grid. Substations of this voltage level are common in the US and serve as critical nodes for stepping down power from transmission lines to local distribution networks. 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 may be classified as a medium-voltage asset depending on its specific role in the grid. The facility's location in the southwestern United States places it within the Western Interconnection, one of the two major alternating current power grids in North America. Charleston Park Substation contributes to the electrical infrastructure serving the surrounding region, supporting residential, commercial, and industrial loads. Its operational status ensures continued reliability for local power distribution. The substation's design and equipment likely include circuit breakers, transformers, and switchgear compliant with IEEE and ANSI standards, ensuring safe and efficient operation within the broader grid network.
Environmental context
The substation is located in a desert region of the southwestern United States, characterized by arid climate and sparse vegetation. Electrical infrastructure in such environments must contend with high ambient temperatures, dust, and limited water resources for cooling. The facility's design likely incorporates measures for thermal management and dust mitigation to maintain operational reliability. The surrounding area is primarily undeveloped, with minimal impact on sensitive ecosystems, though the substation's presence supports energy delivery to urban centers and industrial facilities in the region.
Frequently asked questions
Charleston Park Substation is located in the United States, with approximate coordinates 36.2045 N, -116.1136 W, in the southwestern region of the country.
Charleston Park Substation operates at a voltage of 138 kV, which is a common subtransmission voltage level in the US electrical grid.
Electrical substations in the US are regulated by the North American Electric Reliability Corporation (NERC) under the oversight of the Federal Energy Regulatory Commission (FERC), which enforce reliability and security standards.
A 138 kV substation typically serves as a subtransmission or distribution substation, stepping down voltage from higher transmission levels (e.g., 230 kV or 500 kV) to lower distribution voltages for local delivery to customers.
Substation automation and equipment in the US often comply with IEEE standards, including IEEE C37 for switchgear and IEEE 1585 for communication networks, as well as NERC CIP standards for cybersecurity.
