Overview
West Vaco Substation, operated by PacifiCorp in the United States, is a 230 kV electrical substation serving the regional grid. It plays a key role in transmitting power across the western U.S.
West Vaco Substation is an operational electrical substation located in the United States, managed by PacifiCorp, a major utility serving the western U.S. The facility operates at 230 kV, a standard transmission voltage level that supports bulk power transfer across long distances. As part of PacifiCorp's network, it contributes to grid reliability for residential, commercial, and industrial customers in the region. The substation's technical specifications indicate a voltage level of 230 kV, which is typical for high-voltage transmission infrastructure in the United States. Such facilities are critical for interconnecting generation sources with load centers and are subject to NERC reliability standards to ensure stable grid operation. PacifiCorp, as the owner and operator, adheres to FERC regulations for transmission assets, including maintenance and cybersecurity requirements. Environmentally, the substation's location in a rural area of Wyoming minimizes direct impact on urban populations, though transmission lines may traverse natural habitats. The facility supports the integration of renewable energy sources, such as wind and solar, by providing grid connectivity. Its operational status ensures continued service to the regional power system, enhancing energy security and economic activity in the surrounding communities.
Environmental context
The substation is situated in a semi-arid region of Wyoming, characterized by sagebrush steppe and low population density. Its 230 kV infrastructure supports long-distance power transmission, which can affect local wildlife through corridor fragmentation. However, the facility's rural location reduces exposure to sensitive ecosystems compared to urban substations. The grid connection enables renewable energy integration, contributing to regional decarbonization goals.
