Cedarville Junction Substation - Operational 115/69 kV Substation in California, USA

Cedarville Junction Substation is an operational electrical substation located in California, United States. The facility operates at voltage levels of 115 kV and 69 kV, placing it in the medium-to-high voltage range typical for distribution and sub-transmission networks. As a substation, it serves as a critical node for stepping down transmission voltages for local distribution or interconnecting different parts of the grid. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for bulk power systems. In California, the facility also falls under the jurisdiction of the California Independent System Operator (CAISO) for grid management. The dual voltage configuration suggests it may serve both transmission and distribution functions, common in rural or semi-urban areas. Located in a rural area of Modoc County, the substation likely supports agricultural and residential loads, as well as potential renewable energy integration from nearby solar or wind projects. Its role in maintaining voltage stability and power quality is essential for the local community. The facility's operational status ensures continued reliability for the surrounding electrical infrastructure.

The substation is situated in a rural, semi-arid region of northeastern California, characterized by sagebrush steppe and agricultural land. The local environment is sensitive to electromagnetic fields and habitat fragmentation, though substations typically have a small footprint. The facility's voltage levels and location suggest it may support integration of distributed energy resources, which can reduce transmission losses and environmental impact compared to long-distance power delivery.
