Shelton Substation - Bonneville Power Administration Substation in the United States

Shelton Substation is an operational electrical substation located in the United States, owned and operated by the Bonneville Power Administration (BPA). As part of BPA's high-voltage transmission network, it plays a key role in delivering power across the Pacific Northwest. The substation handles voltages of 230 kV and 115 kV, indicating its function in both bulk power transmission and sub-transmission to local distribution systems. The facility operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which set reliability standards and oversee interstate electricity markets. BPA, a federal power marketing administration, adheres to these standards to ensure grid stability. Shelton Substation supports the electrical infrastructure of the surrounding region, contributing to reliable power supply for residential, commercial, and industrial users. Its location in Washington state places it within a grid that integrates hydroelectric power from the Columbia River system, making it part of a clean energy backbone. The substation's operational status ensures continued service to the community and the broader Western Interconnection.

The substation is situated in a region with significant hydroelectric generation, which reduces reliance on fossil fuels. Its operation supports the integration of renewable energy sources like wind and solar, which are growing in the Pacific Northwest. The facility's voltage levels and grid role help maintain stability, minimizing environmental impacts from power disruptions.
