Overview
Brownlee Substation is an operational 230 kV substation owned by Idaho Power in the United States. It plays a key role in regional grid stability and power transmission.
Brownlee Substation is a high-voltage electrical substation located in the United States, owned and operated by Idaho Power. Operating at 230 kV, it is a critical node in the regional transmission network, facilitating the efficient transfer of electricity from generation sources to distribution systems. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), ensuring compliance with reliability standards for bulk power systems. As a 230 kV facility, it falls within the typical voltage range for transmission-level substations, supporting long-distance power delivery and grid interconnection. Brownlee Substation is strategically positioned to support the electrical infrastructure of the Pacific Northwest, contributing to grid resilience and energy reliability for surrounding communities. Its operation by Idaho Power underscores its importance in the regional power supply chain, serving both urban and rural load centers.
Environmental context
The substation is located in a rural area of the Pacific Northwest, where the local environment is characterized by mountainous terrain and proximity to the Snake River. High-voltage substations like Brownlee can have localized environmental impacts, including electromagnetic fields and land use for transmission corridors. The facility's age and technology level are typical for the region, with modern switchgear and automation likely in place to minimize environmental footprint.
