Overview
Dixonville Substation is an operational electrical substation in Oregon, United States, owned and operated by PacifiCorp. It operates at 230 kV, serving as a key node in the regional transmission grid.
Dixonville Substation is an operational electrical substation located in Oregon, United States. Owned and operated by PacifiCorp, the facility plays a critical role in the regional transmission network, handling high-voltage electricity at 230 kV. As part of the Western Interconnection, it supports the reliable delivery of power across the Pacific Northwest. 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 bulk power systems. At 230 kV, Dixonville Substation is classified as a high-voltage transmission asset, typical for interconnecting major generation sources and load centers. The facility's equipment likely includes circuit breakers, transformers, and switchgear compliant with IEEE and IEC standards. Environmentally, the substation is situated in a rural area of Douglas County, surrounded by forested terrain. Its operation supports grid stability for nearby communities and industrial users, while adhering to environmental regulations for electromagnetic fields and oil containment. The substation's age and maintenance status are not publicly detailed, but its continued operational status indicates ongoing utility investment in grid reliability.
Environmental context
Located in a rural forested region of Oregon, Dixonville Substation operates in an area with moderate wildfire risk, typical of Pacific Northwest transmission infrastructure. The 230 kV voltage level requires clearance corridors that may impact local vegetation, but standard utility practices include vegetation management to reduce fire hazards. The substation's electromagnetic fields are regulated by state and federal guidelines, and oil-filled equipment is subject to spill prevention protocols to protect nearby watersheds.
