Cusick Substation - 230 kV Substation in Washington, United States

Cusick Substation is a 230 kV electrical substation located in Washington, United States. Owned and operated by Bonneville Power Administration (BPA), it plays a role in the high-voltage transmission network that delivers electricity across the Pacific Northwest. The substation is part of BPA's extensive infrastructure, which includes over 15,000 circuit miles of transmission lines. As a 230 kV facility, Cusick Substation operates at a voltage level typical for sub-transmission and transmission applications, connecting regional power sources to distribution networks. The substation is subject to North American Electric Reliability Corporation (NERC) reliability standards and Federal Energy Regulatory Commission (FERC) regulations, ensuring grid stability and compliance with mandatory reliability requirements. BPA, a federal power marketing administration, oversees its operation within the larger Western Interconnection. The substation's location in rural northeastern Washington supports the local grid and contributes to the resilience of the regional electrical infrastructure. Its operational status and integration with BPA's network underscore its importance in maintaining reliable power supply to communities and industries in the area.

Located in a rural area of northeastern Washington, Cusick Substation operates in a region characterized by forested terrain and a continental climate. The substation's 230 kV voltage level indicates its role in long-distance power transmission, which can have environmental considerations such as land use for transmission corridors and potential impacts on local wildlife. The facility's operation under BPA includes adherence to environmental regulations and mitigation practices common to high-voltage infrastructure in the United States.
