Hornsby Substation | 345 kV Electrical Substation in Texas, United States

Hornsby Substation is an operational electrical substation located in Texas, United States, owned and operated by the Lower Colorado River Authority (LCRA). The facility handles voltage levels of 345 kV and 24.9 kV, indicating its role in both high-voltage transmission and local distribution. As part of the LCRA's network, it supports the electric reliability needs of central Texas. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which set standards for grid stability and reliability. The 345 kV voltage level classifies it as a transmission-level asset, critical for long-distance power transfer and interconnection with other utilities. The 24.9 kV side suggests distribution to local customers or industrial loads. Environmentally, the substation is situated in an urbanizing area near Austin, Texas, where demand for electricity is growing. Its role in the LCRA system helps integrate renewable energy sources, such as wind and solar, into the grid. The facility's operational status ensures continued service to the community, supporting both residential and commercial needs.
