Harvalum Substation - 230 kV Electrical Substation in the United States

Harvalum Substation is an operational electrical substation located in the United States, with coordinates 45.728807, -120.705723. The facility operates at a voltage level of 230 kV, classifying it as a high-voltage substation critical for long-distance power transmission and grid interconnection. As a 230 kV substation, Harvalum operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and is subject to Federal Energy Regulatory Commission (FERC) oversight for reliability standards. Such substations typically serve as nodes in the bulk power system, facilitating voltage transformation and power distribution to regional networks. The substation's location in a rural area of the United States suggests it likely supports agricultural or small community loads, contributing to local energy resilience. Its operational status ensures continued integration of generation sources and maintenance of grid stability in the region.

The substation is situated in a rural area of Washington state, characterized by semi-arid climate and agricultural land use. High-voltage substations like Harvalum are typically designed with minimal environmental footprint, though they require cleared rights-of-way that can affect local habitats. The facility's operation supports efficient power transmission, reducing line losses and supporting renewable energy integration in the region.
