Overview
Santa Anna Substation is an operational electrical substation in Texas, United States, owned and operated by the Lower Colorado River Authority. It operates at a voltage of 138 kV.
Santa Anna Substation is an operational electrical substation located in Texas, United States. Owned and operated by the Lower Colorado River Authority, this facility plays a key role in the regional power grid. The substation operates at a voltage of 138 kV, which is typical for sub-transmission and distribution-level infrastructure in the United States. As part of the Lower Colorado River Authority's network, the substation is subject to regulatory oversight by the Federal Energy Regulatory Commission (FERC) and must comply with North American Electric Reliability Corporation (NERC) reliability standards. These standards ensure grid stability and security, particularly for facilities that interconnect with the broader transmission system. The 138 kV voltage level indicates this substation likely serves as a distribution hub for local communities and industrial customers. The Santa Anna Substation is situated in a rural area of central Texas, where it supports the electrical needs of the surrounding region. Its operational status and compliance with NERC standards contribute to the reliability of the local grid. The substation's role in stepping down voltage from higher transmission lines to distribution levels is critical for delivering electricity to end-users.
Environmental context
The substation is located in a rural area of central Texas, characterized by a semi-arid climate with hot summers and mild winters. The surrounding landscape includes agricultural land and grasslands. Electrical infrastructure in such areas must be designed to withstand extreme weather events, including heatwaves and occasional severe storms. The substation's operation is subject to environmental regulations that manage potential impacts such as electromagnetic fields and stormwater runoff.
