Overview
Stegall Substation is an operational electrical substation in the United States, operated by the Western Area Power Administration. It operates at a voltage of 230 kV, indicating a high-voltage transmission-level facility.
Stegall Substation is a high-voltage electrical substation located in the United States, operated by the Western Area Power Administration (WAPA). The facility operates at 230 kV, placing it within the transmission-level infrastructure that is critical for bulk power transfer across regional grids. As part of WAPA's network, this substation supports the reliable delivery of federal hydropower to utilities and communities in the western United States. The substation's technical specifications include a voltage level of 230 kV, which is typical for major transmission substations that interconnect high-voltage lines. Such facilities are essential for stepping down power from extra-high-voltage lines or for switching and distributing electricity within the grid. The operational status is active, and the substation is likely equipped with modern switchgear and protection systems to ensure grid stability. From an environmental perspective, Stegall Substation plays a role in integrating renewable energy sources, such as wind and solar, into the grid. Its location in the western U.S. places it within a region with significant renewable energy development. The substation's operation under WAPA ensures compliance with NERC reliability standards and FERC regulations, contributing to the overall resilience and efficiency of the national electrical infrastructure.
Environmental context
The substation's location in the western United States places it within a region characterized by diverse geography, including plains and arid areas. The facility's high-voltage operation supports the integration of renewable energy sources like wind and solar, which are abundant in the region. The surrounding environment may experience seasonal temperature extremes, influencing grid demand and operational planning. The substation's design and maintenance consider local climate conditions to ensure reliable performance.
