Overview
BPA Trego Substation is an operational electrical substation in the United States, operated by the Bonneville Power Administration. It operates at 115 kV, supporting regional grid stability.
BPA Trego Substation is an operational electrical substation located in the United States, managed by the Bonneville Power Administration (BPA). As a 115 kV substation, it plays a role in the transmission network, facilitating voltage transformation and power distribution within the region. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which set reliability standards for the bulk power system. BPA, a federal power marketing administration, ensures compliance with these standards to maintain grid stability and security. Situated in a rural area near Trego, Montana, the substation contributes to the local electrical infrastructure by connecting renewable energy sources and supporting load centers. Its operation is integral to the reliability of the Pacific Northwest power grid, serving communities and industries in the region.
Environmental context
The substation is located in a rural, forested area of northwestern Montana, near the Kootenai National Forest. The surrounding environment is characterized by mountainous terrain and diverse wildlife habitats. Electrical infrastructure in such areas must consider wildfire risk and vegetation management to ensure safe operation. The 115 kV voltage level indicates a sub-transmission role, balancing local distribution needs with regional grid connectivity.
Frequently asked questions
