Distribution Substation - 115 kV Electrical Substation in Washington, United States

Distribution Substation is an operational electrical substation located in Washington State, United States, and operated by Puget Sound Energy. The facility operates at a voltage of 115 kV, placing it within the medium-voltage distribution tier that serves local communities and industrial customers. As part of the broader Pacific Northwest grid, this substation plays a role in delivering reliable electricity to the region. 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 transmission and distribution assets. In the United States, substations like this one are critical nodes that step down high-voltage transmission power for local distribution, often incorporating automation standards such as IEC 61850 for efficient monitoring and control. Environmentally, the substation is situated in a region characterized by temperate rainforest climate and proximity to the Puget Sound. Its operation supports the integration of renewable energy sources, such as hydropower from the Columbia River system, into the local grid. The facility's role in maintaining voltage stability and power quality is essential for the surrounding urban and rural communities, contributing to the overall resilience of the electrical infrastructure in Washington State.

The substation is located in the Pacific Northwest, a region with abundant hydropower resources and a growing share of wind and solar generation. Its 115 kV voltage level indicates a distribution role, serving local load centers while supporting grid stability. The area's dense forest cover and proximity to the Puget Sound require careful siting to minimize ecological disruption, though specific environmental impacts are managed through standard utility practices.
