Overview
North Substation is an operational electrical substation in the United States, serving the grid with a voltage level of 115 kV. It plays a key role in regional power distribution and grid stability.
North Substation is an operational electrical substation located in the United States, with coordinates 47.684076, -122.319398. It operates at a voltage of 115 kV, classifying it as a medium-voltage substation typical of distribution-level infrastructure. The facility is part of the broader North American power grid, which is regulated by NERC reliability standards and FERC oversight for transmission-level assets. The substation's technical specifications include a voltage of 115 kV, which is common for sub-transmission and distribution networks that connect bulk power systems to local utilities. In the United States, substations like North Substation are critical for stepping down voltage from high-voltage transmission lines to lower levels suitable for industrial, commercial, and residential use. The facility likely employs standard switchgear and automation systems compliant with ISO/IEC 61850 for substation automation. Operationally, North Substation contributes to grid stability and reliability in its region. Its location in an urban or suburban area (based on coordinates near Seattle) suggests it serves a significant population center. The substation's age and specific equipment are not detailed, but its operational status indicates ongoing maintenance and compliance with regulatory frameworks. The facility's role in the electrical infrastructure supports local economic activity and community services.
Environmental context
The substation is located in a region with a temperate maritime climate, which can affect equipment performance and maintenance schedules. Urban proximity means the facility must manage electromagnetic field (EMF) considerations and visual impact, though modern substations are often designed with mitigation measures. The 115 kV voltage level indicates a balance between transmission efficiency and local distribution needs, with typical environmental considerations including oil containment for transformers and noise reduction from cooling fans.
Frequently asked questions
North Substation is located in the United States at coordinates 47.684076, -122.319398, near the Seattle metropolitan area.
North Substation operates at a voltage of 115 kV, which is typical for sub-transmission and distribution substations in the United States.
North Substation is currently operational, indicating it is actively serving the electrical grid.
Substations in the United States must comply with NERC reliability standards for grid stability and FERC regulations for transmission-level assets. Additionally, ISO/IEC 61850 standards are often used for substation automation.
A 115 kV substation typically steps down voltage from high-voltage transmission lines (e.g., 230 kV or higher) to distribution levels (e.g., 12 kV or 34.5 kV) for local delivery to industrial, commercial, and residential customers.
