Overview
Three Mile Knoll Substation is an operational electrical substation in the United States, handling voltages of 345 kV and 138 kV. It plays a key role in regional grid stability.
Three Mile Knoll Substation is an operational electrical substation located in the United States, with coordinates 42.710535, -111.596322. The facility operates at high voltage levels of 345 kV and 138 kV, indicating its importance in the transmission network for long-distance power transfer and grid interconnection. Operating under the regulatory framework of the United States, the substation adheres to NERC reliability standards and FERC regulations for transmission-level assets. The dual voltage levels suggest it serves as a step-down or interconnection point between bulk transmission and sub-transmission systems, typical for facilities supporting regional power distribution. The substation's location in a rural area of the western US underscores its role in connecting remote generation sources to load centers. Its operational status ensures continued reliability for the local grid, contributing to the stability of the broader electrical infrastructure in the region.
Environmental context
The substation is situated in a rural area of Idaho, characterized by open terrain and proximity to agricultural land. Its high-voltage equipment is designed to withstand local weather conditions, including snow and wind. The facility's operation supports the integration of renewable energy sources from the region, such as wind and solar, into the grid.
