Overview
Eagle Lake Substation is an operational electrical substation in Washington State, United States, owned and operated by the Bonneville Power Administration. It operates at 115 kV, serving the regional power grid.
Eagle Lake Substation is an operational electrical substation located in Washington State, United States. Owned and operated by the Bonneville Power Administration (BPA), it is part of the federal power marketing administration's extensive transmission network in the Pacific Northwest. The substation operates at a voltage of 115 kV, classifying it as a sub-transmission or distribution-level facility within the regional grid. As a BPA asset, Eagle Lake Substation falls under the regulatory oversight of the Federal Energy Regulatory Commission (FERC) and must comply with North American Electric Reliability Corporation (NERC) reliability standards. BPA's transmission system is a critical component of the Western Interconnection, serving federal hydroelectric projects and integrating renewable energy sources. The 115 kV voltage level is typical for regional distribution and interconnection of smaller generation facilities. The substation plays a role in maintaining grid stability and delivering electricity to local communities and industries in central Washington. Its location near agricultural areas and the Columbia River basin underscores its importance in supporting both rural and urban energy needs. The facility contributes to the resilience of the regional power system through BPA's robust maintenance and operational protocols.
Environmental context
The substation is situated in a semi-arid region of central Washington, characterized by agriculture and proximity to the Columbia River. Electrical infrastructure in this area must withstand seasonal temperature extremes and occasional wildfire risks. The 115 kV voltage level indicates a moderate scale facility, typically located in rural or suburban settings to support local distribution networks. BPA's operations emphasize environmental stewardship, including measures to protect avian species and minimize electromagnetic field impacts.
