Kartchner Substation - Operational 115 kV Substation in the United States

Kartchner Substation is an operational electrical substation located in the United States, with coordinates 31.566093, -110.308966. The facility operates at a voltage of 115 kV, placing it within the medium-voltage range typical for distribution and sub-transmission networks. As a substation, it serves as a critical node for stepping down high-voltage electricity from transmission lines to lower voltages suitable for local distribution. The substation operates under the regulatory framework of the United States, which includes NERC reliability standards for grid stability and FERC oversight for interstate electricity transmission. The 115 kV voltage level is commonly used for sub-transmission systems that connect bulk power transmission to distribution networks. Facilities like Kartchner Substation are essential for maintaining voltage regulation and ensuring reliable power delivery to end users. Located in a region with varied geography, the substation supports the electrical infrastructure of its surrounding area. Its operational status indicates ongoing contribution to the local power grid. The facility's role in voltage transformation and grid interconnection underscores its importance in the broader electrical network, facilitating efficient and reliable electricity supply.

The substation's location in the southwestern United States places it in a region with high solar insolation and arid climate, which influences energy demand patterns and grid management. The 115 kV voltage level suggests it serves a mix of residential, commercial, and possibly industrial loads. Substations in such areas often integrate renewable energy sources like solar farms, requiring careful voltage regulation and grid stability measures.
