Electron Heights Substation - 115 kV Substation in Washington, United States

Electron Heights Substation is an operational electrical substation located in Washington, United States, owned and operated by Puget Sound Energy. The facility operates at a voltage of 115 kV, classifying it as a medium-voltage substation that plays a role in local power distribution and transmission. As part of the US electrical infrastructure, this substation adheres to NERC reliability standards and FERC regulations for grid stability. The 115 kV voltage level is typical for sub-transmission or distribution substations, connecting higher-voltage transmission lines to lower-voltage distribution networks. Puget Sound Energy, a major utility in the Pacific Northwest, manages this asset within its regional grid. The substation's location in Washington state places it within a region with diverse energy sources, including hydroelectric power from the Columbia River system. Its operational status ensures continued support for local electricity demand, contributing to the resilience of the surrounding community's power supply.

The substation is situated in a region with significant hydroelectric generation, which influences grid operations and environmental considerations. Its urban-rural interface location may affect land use and wildlife corridors, though specific impacts depend on local siting practices. The 115 kV voltage level indicates moderate electromagnetic field exposure, managed through standard utility practices.
