Massachusetts Substation - High-Voltage Electrical Substation in the United States

Massachusetts Substation is an operational electrical substation located in the United States, with coordinates 47.588727, -122.335920. The facility operates at voltage levels of 230 kV and 115 kV, indicating its role in high-voltage transmission and sub-transmission networks. As a substation, it serves as a critical node for stepping down voltage and routing electricity within the regional grid. The substation operates under the regulatory framework of the United States, which includes NERC reliability standards and FERC oversight for transmission-level assets. The facility's voltage class places it in the medium-to-high range for substations, typical for urban or industrial supply. The location near Seattle suggests it supports a densely populated area with significant electricity demand. Environmentally, the substation's operation involves managing electromagnetic fields and ensuring minimal impact on surrounding land use. Its urban setting requires compliance with local noise and safety regulations. The facility contributes to grid resilience by providing voltage regulation and switching capabilities, essential for maintaining reliable power supply to homes and businesses.

The substation is located in an urbanized area near Seattle, Washington, where land use is dominated by residential and commercial development. Its operation involves managing electromagnetic fields and noise, with typical mitigation measures such as buffer zones and equipment enclosures. The facility's high voltage levels require careful siting to avoid interference with nearby infrastructure and to ensure public safety.
