Angel Mounds Transmission Substation - 138 kV Substation in the United States

Angel Mounds Transmission Substation is a high-voltage electrical substation located in the United States, owned and operated by CenterPoint Energy. The facility operates at a voltage of 138 kV, classifying it as a transmission-level asset within the North American power grid. As a substation, it plays a critical role in stepping down voltage for distribution or interconnecting transmission lines. 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 bulk power systems. CenterPoint Energy, a major utility in the region, ensures compliance with these standards to maintain grid stability. The 138 kV voltage level is typical for sub-transmission or transmission applications, supporting the delivery of electricity from generation sources to load centers. Located in the United States, the substation contributes to the reliability of the local electrical infrastructure. Its operational status ensures continued service to the surrounding community, supporting residential, commercial, and industrial customers. The facility's integration into the wider grid underscores its importance in maintaining a stable and resilient power supply.

The substation is situated in a region with a temperate climate, where seasonal variations can impact grid demand. Its location near the Ohio River may influence environmental considerations such as flood risk and vegetation management. The facility's voltage level and role in the transmission network mean it is designed to minimize electromagnetic field exposure and comply with environmental regulations.
