Overview
Rosemore Substation is an operational 230 kV substation owned by the Modesto Irrigation District in California, United States. It plays a key role in regional grid stability and power distribution.
Rosemore Substation is an operational electrical substation located in California, United States, owned and operated by the Modesto Irrigation District. The facility operates at a voltage of 230 kV, classifying it as a high-voltage transmission substation critical for bulk power transfer and grid reliability. 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 transmission-level assets. As part of the Modesto Irrigation District's infrastructure, it supports the local electric grid serving agricultural, residential, and industrial customers in the Central Valley region. Environmentally, the substation's location in an agricultural and urbanizing area requires careful management of electromagnetic fields and vegetation clearance to minimize ecological impact. Its role in distributing power from generation sources to load centers contributes to the region's energy resilience and economic activity.
Environmental context
The substation is situated in California's Central Valley, a region with significant agricultural activity and urban development. Its 230 kV voltage level indicates a key role in long-distance power transmission, which can have land-use implications for transmission corridors. Vegetation management under power lines is necessary to prevent fire risks, especially in California's dry climate. The facility's proximity to populated areas requires adherence to safety and electromagnetic field guidelines.
