Overview
Union Valley Substation is an operational electrical substation in California, United States, operating at 230 kV. It plays a key role in regional grid stability and power distribution.
Union Valley Substation is an operational electrical substation located in California, United States. The facility operates at a voltage of 230 kV, classifying it as a high-voltage substation critical for transmission-level power distribution. Its location in the Sierra Nevada region supports the grid infrastructure serving both urban and rural areas. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), ensuring compliance with reliability standards for bulk power systems. As a 230 kV facility, it is typical of medium-to-high voltage substations that form the backbone of the US electrical grid, facilitating long-distance power transmission and interconnection. Environmentally, the substation's location in a forested mountainous area requires careful management of vegetation and wildlife interactions. Its role in the grid helps integrate renewable energy sources from the region, such as hydroelectric and solar power, contributing to California's clean energy goals. The facility's operational status ensures continued reliability for local communities and industries.
Environmental context
Located in the Sierra Nevada region of California, the substation operates in a forested, mountainous environment. The area experiences seasonal wildfire risks, requiring vegetation management and fire prevention measures. The substation's high-voltage infrastructure supports the integration of renewable energy from nearby hydroelectric and solar facilities, aligning with California's renewable portfolio standards. Its rural location minimizes direct urban environmental impacts but necessitates careful siting to avoid sensitive habitats.
