Overview
Sweptwing Substation is an operational electrical substation located in the United States, serving the local grid with voltage transformation and distribution functions.
Sweptwing Substation is an operational electrical substation located in the United States, specifically at coordinates 47.423548, -122.298177, which places it in the Pacific Northwest region. As a substation, it plays a critical role in the electrical infrastructure by stepping down high-voltage transmission power to lower voltages for distribution to residential, commercial, and industrial customers. The facility is part of the broader interconnected grid that ensures reliable electricity supply. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which set standards for grid reliability and security. Substations of this type typically handle voltages ranging from 69 kV to 345 kV, depending on their role in the transmission and distribution network. The facility's location in a suburban area near Seattle suggests it supports a mix of urban and industrial loads. Sweptwing Substation contributes to the stability and resilience of the local electrical grid, particularly in a region with growing energy demands and increasing integration of renewable energy sources. Its operational status ensures continued service to the community, and its design likely incorporates modern automation and protection systems in line with industry standards such as ISO/IEC 61850 for substation automation.
Environmental context
The substation is located in a temperate coastal region with mild, wet winters and dry summers. Its urban-suburban setting means it is subject to typical environmental considerations such as stormwater management and electromagnetic field (EMF) mitigation. The facility's design likely includes measures to minimize visual impact and noise, and it operates within regulatory limits for EMF exposure. The surrounding area is characterized by mixed residential and commercial development, with proximity to Puget Sound, which may require additional environmental protections for water quality.
