Hubbell Substation: Operational Electrical Infrastructure in the United States

Hubbell is an operational electrical substation located in the United States, with coordinates 39.211946, -85.078536. The facility operates at voltage levels of 138,000 V and 69,000 V, indicating its role in both transmission and sub-transmission networks. As a substation, it is a critical node for stepping down high-voltage electricity from transmission lines to lower voltages for local distribution. 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 the bulk power system. The facility's dual voltage levels suggest it may serve as a step-down transformer station, connecting high-voltage transmission lines to lower-voltage distribution networks. Such substations are common in the United States, where aging infrastructure is increasingly being upgraded to meet modern grid demands. Environmentally, the substation's location in a rural or suburban area of the Midwest likely supports agricultural or residential communities. Its operation contributes to grid resilience by ensuring stable voltage and frequency control. Its operational status indicates it is actively serving the local power grid, which is essential for economic activity and daily life in the region.

The substation is situated in a region with a temperate climate, typical of the Midwestern United States. Its voltage levels suggest it is part of the transmission grid, which can have environmental impacts through land use and electromagnetic fields. However, substations generally have a smaller footprint than power plants. The facility's role in grid stability helps integrate renewable energy sources, reducing reliance on fossil fuels.
