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

Colville Substation is an operational electrical substation located in Washington, United States. Owned and operated by the Bonneville Power Administration (BPA), it plays a key role in the regional transmission network. The substation operates at a voltage of 115 kV, classifying it as a medium-voltage facility within the broader electrical infrastructure. As part of BPA's system, Colville Substation is subject to North American Electric Reliability Corporation (NERC) reliability standards and Federal Energy Regulatory Commission (FERC) regulation. These frameworks ensure grid stability and compliance with mandatory reliability requirements. The substation's 115 kV voltage level is typical for sub-transmission and distribution support in rural and semi-urban areas. The substation contributes to the electrical supply for the Colville area and surrounding communities. Its operational status and connection to BPA's extensive network underscore its importance in maintaining reliable power delivery. The facility's location in northeastern Washington supports local industrial and residential electricity needs.

Located in a rural area of northeastern Washington, the substation's environmental context is shaped by its proximity to forested lands and the Columbia River basin. Electrical infrastructure like Colville Substation must consider wildfire risk, vegetation management, and wildlife protection. The 115 kV voltage level indicates a moderate footprint, with typical environmental considerations including electromagnetic field management and habitat conservation.
