South Grandview Substation: 161 kV Electrical Substation in the United States

South Grandview Substation is an operational electrical substation located in the United States, owned and operated by Alliant Energy. The facility operates at a voltage of 161 kV, placing it in the medium-to-high voltage range typical for sub-transmission and distribution substations. As part of Alliant Energy's network, it plays a role in delivering electricity to customers in the region. The substation's technical specifications indicate a voltage level of 161 kV, which is common for substations that step down power from high-voltage transmission lines to lower voltages for local distribution. In the United States, such facilities are subject to reliability standards set by the North American Electric Reliability Corporation (NERC) and are regulated by the Federal Energy Regulatory Commission (FERC) for interstate aspects. Alliant Energy, as a utility, must comply with these frameworks to ensure grid stability and safety. Operationally, South Grandview Substation contributes to the electrical infrastructure's resilience and capacity in its area. Its location near coordinates 42.47727, -90.666004 suggests it serves a region that may include both urban and rural loads. The substation's role in voltage regulation and power distribution is critical for maintaining reliable electricity supply to homes, businesses, and industries, supporting economic activity and community well-being.

The substation's location in the United States places it within a regulatory environment that emphasizes grid reliability and environmental compliance. While substations themselves have a relatively small environmental footprint, their operation is tied to the broader electrical grid, which can impact land use and wildlife. The 161 kV voltage level indicates it is part of the sub-transmission network, often located in areas that balance access to load centers with environmental considerations. Alliant Energy's operations are subject to state and federal environmental regulations, including those related to electromagnetic fields and equipment maintenance.
