Portland Switch Substation - 115 kV Electrical Substation in the United States

Portland Switch Substation is an operational electrical substation located in the United States, owned and operated by PowerSouth Energy Cooperative. The facility operates at a voltage of 115 kV, placing it in the medium-voltage range typical for distribution and sub-transmission substations. As part of PowerSouth's network, it plays a role in delivering electricity to customers in the region. The substation's technical specifications indicate a voltage level of 115 kV, which is common for substations that step down power from higher transmission voltages for local distribution. In the United States, such facilities are subject to NERC reliability standards and FERC regulations, ensuring grid stability and compliance with federal oversight. The substation's equipment likely includes switchgear, transformers, and protection systems designed to maintain safe and reliable operation. Operationally, Portland Switch Substation contributes to the electrical infrastructure serving the surrounding area. Its location in the United States places it within a well-regulated grid environment, where reliability and safety are prioritized. The substation supports PowerSouth Energy Cooperative's mission to provide dependable power to its member-owners, and its continued operation is essential for local energy distribution.

The substation is located in a region with a temperate climate, which influences equipment design and maintenance schedules. Its voltage level and role in the grid mean it has a moderate environmental footprint, primarily related to land use and electromagnetic fields. The facility is situated in an area that may experience seasonal weather variations, requiring robust infrastructure to ensure continuous operation.
