Bothell Substation: Operational Electrical Substation in the United States

Bothell Substation is an operational electrical substation located in the United States, serving as a key node in the regional power grid. The facility operates at voltage levels of 230 kV and 115 kV, indicating its role in both high-voltage transmission and sub-transmission networks. This scale places it within the medium to large category for substations, typical of facilities that interconnect major power lines and distribute electricity to local grids. The substation operates under the regulatory framework of the United States, which includes NERC reliability standards and FERC oversight for transmission-level assets. The facility's dual voltage levels suggest it likely contains transformers to step down power from 230 kV to 115 kV, a common configuration for connecting bulk transmission to distribution systems. Such substations are critical for maintaining grid reliability and are often equipped with modern automation systems compliant with ISO/IEC 61850 standards. Located in the Pacific Northwest, Bothell Substation supports the electrical infrastructure of a region known for its hydroelectric power generation and growing urban demand. The facility's operational status ensures continued service to residential, commercial, and industrial customers in the area. Its role in voltage regulation and power flow management contributes to the overall stability and resilience of the regional grid.

The substation's location in Bothell, Washington, places it within a temperate rainforest climate with high precipitation, which can affect equipment maintenance and insulation requirements. The surrounding urban and suburban development increases demand for reliable power, while proximity to natural areas necessitates careful management of electromagnetic fields and stormwater runoff. The facility's voltage levels indicate its importance in integrating renewable energy sources common in the Pacific Northwest, such as hydroelectric and wind power.
