Evergreen Substation - 115 kV Substation in Vancouver, Washington

Evergreen Substation is an operational electrical substation located in Vancouver, Washington, United States. Owned and operated by Clark Public Utilities, the facility plays a key role in the local power distribution network. As a 115 kV substation, it is classified as a medium-voltage asset within the broader electrical infrastructure. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which set reliability standards for transmission and distribution assets. The 115 kV voltage level is typical for sub-transmission systems that connect bulk power sources to distribution networks, serving urban and suburban areas in the Pacific Northwest. As part of Clark Public Utilities' grid, Evergreen Substation contributes to reliable electricity delivery for residential, commercial, and industrial customers in the Vancouver area. Its operational status ensures continued support for local energy needs, with the utility's focus on maintaining infrastructure resilience and compliance with NERC standards.

The substation is located in an urbanized area of Vancouver, Washington, within the Columbia River Gorge region. The local environment is characterized by temperate climate and proximity to the Columbia River, which influences energy demand patterns. Electrical infrastructure in this area must consider wildfire risk mitigation and vegetation management, common concerns for utilities in the Pacific Northwest.
