Overview
Terminal substation is an operational electrical substation in the United States, handling voltages of 345 kV, 138 kV, and 46 kV. It plays a key role in regional grid stability.
Terminal substation is an operational electrical substation located in the United States, with coordinates 40.757568, -112.006626. It operates at multiple voltage levels including 345 kV, 138 kV, and 46 kV, indicating its role in both high-voltage transmission and sub-transmission. The facility is part of the broader North American power grid, which is regulated by NERC reliability standards and FERC oversight. The substation's voltage levels suggest it serves as a critical node for power distribution, likely connecting long-distance transmission lines to local distribution networks. In the U.S., substations of this scale are typically equipped with advanced automation systems, often adhering to IEC 61850 standards for communication and control. The facility's location in the western United States places it within the Western Interconnection, one of the major synchronized grids in North America. Operationally, Terminal substation contributes to grid reliability by enabling voltage transformation and power routing. Its presence supports the surrounding community's electrical infrastructure, ensuring stable electricity supply for residential, commercial, and industrial users. The substation's age and specific technology are not detailed, but its operational status confirms its ongoing importance to the regional power system.
Environmental context
The substation is situated in an area with a semi-arid climate, typical of the western United States. Its operation involves high-voltage equipment that requires careful management of electromagnetic fields and potential oil leaks from transformers. The facility's location near urban or natural areas may necessitate adherence to environmental regulations regarding noise, visual impact, and wildlife protection. Proper maintenance and modern technology help mitigate environmental risks.
Frequently asked questions
Terminal substation is located in the United States at coordinates 40.757568, -112.006626. It operates within the Western Interconnection grid.
Terminal substation handles multiple voltage levels: 345 kV (high-voltage transmission), 138 kV (sub-transmission), and 46 kV (distribution). This range indicates its role in stepping down power from long-distance lines to local networks.
Terminal substation is currently operational, meaning it is actively used for voltage transformation and power distribution within the electrical grid.
US substations are subject to NERC reliability standards for grid stability and FERC regulation for interstate transmission. Additionally, IEC 61850 standards for substation automation are commonly adopted for communication and control systems.
By transforming high-voltage transmission power to lower voltages for distribution, Terminal substation ensures stable electricity supply to end-users. Its multiple voltage levels allow it to serve as a critical node for power routing and grid balancing.
