Point of Rocks Substation - 230 kV PacifiCorp Facility in Wyoming

Point of Rocks Substation is a high-voltage electrical substation located in Sweetwater County, Wyoming, United States. Operated by PacifiCorp, it operates at 230 kV, a standard transmission voltage level that supports bulk power transfer across the western U.S. grid. The facility is part of PacifiCorp's extensive network serving customers in six western states. As a 230 kV substation, Point of Rocks is classified as a high-voltage transmission asset, critical for long-distance electricity transport. It likely includes switchgear, transformers, and protection systems compliant with NERC reliability standards and FERC regulations. The substation's design may incorporate automation per IEC 61850 standards, typical for modern U.S. substations. The substation's location in rural Wyoming places it in a region with significant wind energy resources and mining operations. It supports grid stability for local communities and industrial loads, while also facilitating renewable energy integration. Its operational status ensures continued reliability for the surrounding area.

The substation is situated in a semi-arid region of Wyoming, characterized by sagebrush steppe and low precipitation. Its operation involves minimal direct environmental impact, though transmission lines may affect local wildlife and habitats. The facility's 230 kV voltage level indicates a role in long-distance power transfer, potentially connecting wind farms to load centers, which supports renewable energy goals.
