Valleyway Substation - 115 kV Electrical Substation in Spokane Valley, Washington

Valleyway Substation is an operational electrical substation located in Spokane Valley, Washington, United States. Owned and operated by Vera Water & Power, this facility plays a key role in the regional electrical infrastructure by stepping down transmission voltages for local distribution. The substation operates at a voltage of 115 kV, which is typical for sub-transmission and distribution substations in the United States. As part of the U.S. electrical grid, Valleyway Substation operates under the regulatory framework established by the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These standards ensure grid reliability and security, including compliance with NERC's Critical Infrastructure Protection (CIP) standards. The substation likely employs standard automation and protection systems, such as those based on IEC 61850, to monitor and control power flow. The substation's location in Spokane Valley places it within a growing urban area, supporting residential, commercial, and industrial customers. Its operation contributes to grid stability and reliability in the region, particularly during peak demand periods. Vera Water & Power, a public utility, manages the facility to ensure consistent power delivery to its service area.

The substation is situated in Spokane Valley, a region with a semi-arid climate and seasonal temperature extremes. The facility's design and operation consider local environmental conditions, including wildfire risk and snow loads. As an electrical substation, its environmental impact is primarily related to electromagnetic fields and potential oil leaks from transformers, which are managed through standard containment and monitoring practices.
