Overview
Center 345kV Switchyard is an operational substation in the United States, operating at 345kV and 230kV voltage levels, serving as a critical node in the regional transmission grid.
Center 345kV Switchyard is a high-voltage substation located in the United States, with coordinates near 47.076082, -101.199321. The facility operates at 345kV and 230kV, placing it in the large-scale category for electrical infrastructure, essential for long-distance power transmission and grid stability. As a substation in the United States, it operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) reliability standards and Federal Energy Regulatory Commission (FERC) oversight for transmission-level assets. The dual voltage levels indicate its role in stepping down power from extra-high-voltage transmission to sub-transmission or distribution networks, typical for interconnecting major power sources with load centers. The substation's location in a rural area of the central United States suggests it likely serves as a key interconnection point for regional power flows, supporting grid reliability and enabling the integration of diverse generation sources. Its operational status ensures continued contribution to the stability of the local and regional electrical grid.
Environmental context
The substation is situated in a rural area of North Dakota, characterized by open plains and agricultural land. The local environment is subject to extreme weather conditions, including cold winters and occasional severe storms, which can impact grid infrastructure. The facility's design and maintenance must account for these conditions to ensure reliable operation and minimize environmental risks such as oil spills from transformers or electromagnetic field effects.
