Overview
Porter Rockwell Substation is an operational 138 kV substation owned by Rocky Mountain Power in Utah, United States. It plays a key role in regional grid stability.
Porter Rockwell Substation is an electrical substation located in Utah, United States, owned and operated by Rocky Mountain Power. The facility operates at 138 kV, a common transmission voltage level that supports medium-scale power distribution across the region. As part of the Western Interconnection, this substation contributes to the reliability of the local electrical grid. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for bulk power systems. Rocky Mountain Power, a subsidiary of PacifiCorp, serves approximately 1.2 million customers across six western states, and this substation is integral to its transmission network in Utah. Environmentally, the substation is situated in a semi-arid region near the Wasatch Range. Its operation supports urban and suburban communities in Salt Lake County, ensuring stable electricity supply for residential, commercial, and industrial users. The facility's 138 kV voltage level indicates it serves as a critical node for local grid stability and load balancing.
Environmental context
The substation is located in a semi-arid climate zone near the Wasatch Front, an area with growing urban development. Its 138 kV voltage level suggests it is a key component for distributing power to nearby communities, supporting both residential and commercial loads. The facility's operation aligns with regional grid reliability requirements, and its location away from sensitive ecological areas minimizes direct environmental impact.
