Calarnus Substation - Operational 115 kV Substation in the United States

Calarnus Substation is an operational electrical substation located in the United States, with coordinates 42.249942, -99.980971. The facility operates at a voltage level of 115 kV, which classifies it as a medium-voltage substation typically used for subtransmission or distribution within the electrical grid. The substation operates under the regulatory framework of the United States, which includes NERC reliability standards for grid stability and FERC oversight for transmission-level assets. As a 115 kV facility, it likely serves as an interface between higher-voltage transmission lines and lower-voltage distribution networks, supporting local electricity delivery. This substation contributes to the reliability of the regional power grid by stepping down voltage for distribution to end-users. Its operational status ensures continued service to the surrounding area, supporting residential, commercial, and industrial electricity needs.

The substation is located in a rural area of the United States, where electrical infrastructure supports agricultural and small community loads. The 115 kV voltage level indicates it is part of the subtransmission network, which typically has lower environmental impact than high-voltage transmission lines. The facility's operation aligns with NERC standards to minimize risks to grid stability and local ecosystems.
