Caples Substation - Operational 115 kV Electrical Substation in the United States

Caples Substation is an operational electrical substation located in the United States, with coordinates 45.635169, -122.621965. Operating at a voltage of 115 kV, it is classified as a medium-voltage substation, typical for sub-transmission and distribution networks in North America. The facility is part of the broader electrical infrastructure that supports power delivery to industrial, commercial, and residential consumers. 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 115 kV facility, it likely incorporates standard substation automation and protection systems, such as those based on IEC 61850, to ensure safe and efficient operation. The location in the Pacific Northwest suggests it may be integrated with the region's hydroelectric and renewable energy resources. Caples Substation contributes to the reliability and resilience of the local power grid, facilitating voltage transformation and power routing. Its operational status indicates ongoing maintenance and compliance with industry standards. The substation's role in the electrical infrastructure supports economic activity and community services in the surrounding area, highlighting its importance to regional energy security.

The substation is situated in an urban or suburban area of the Pacific Northwest, a region characterized by a mix of residential, commercial, and industrial land uses. The local environment includes proximity to the Columbia River and its tributaries, which support hydroelectric generation and influence grid operations. The facility's design and operation must consider electromagnetic field management, oil containment for transformers, and noise mitigation to minimize impact on surrounding communities and ecosystems.
