McGill Substation - 115 kV Electrical Substation in the United States

McGill Substation is an operational electrical substation located in the United States, owned and operated by Portland General Electric. The facility operates at a voltage of 115 kV, classifying it as a medium-voltage substation within the transmission and distribution network. It plays a key role in the local electrical infrastructure, serving the Portland metropolitan area. As a substation operating under the jurisdiction of the United States, it adheres to NERC reliability standards and FERC regulations for transmission-level assets. The 115 kV voltage level is typical for sub-transmission or distribution substations, which are critical for stepping down power from higher voltage transmission lines to lower voltages for local distribution. Portland General Electric, the owner and operator, is a major utility in the Pacific Northwest, serving over 800,000 customers. The substation's location in an urban area near Portland, Oregon, underscores its importance in maintaining grid reliability for residential, commercial, and industrial customers. Its operational status ensures continued support for the regional power grid, contributing to the stability and resilience of the electrical infrastructure in the region.

The substation is situated in an urban environment in the Pacific Northwest, a region known for its temperate climate and significant hydroelectric power generation. The facility's operation supports the integration of renewable energy sources, such as hydropower and wind, into the grid. Its urban location means it is subject to local land use regulations and may have measures in place to mitigate visual and noise impacts on surrounding communities.
