Overview
San Andres Substation is an operational electrical substation in Texas, United States, operated by Oncor. It operates at a voltage of 138 kV, serving as a key node in the regional transmission grid.
San Andres Substation is an operational electrical substation located in Texas, United States, and operated by Oncor. The facility operates at a voltage of 138 kV, placing it within the high-voltage transmission network that supports the Electric Reliability Council of Texas (ERCOT) grid. As a substation, it plays a critical role in stepping down transmission-level voltages for distribution or interconnecting generation sources. The substation is part of Oncor's extensive transmission and distribution system, which serves millions of customers across Texas. Operating under the regulatory oversight of the Public Utility Commission of Texas (PUCT) and in compliance with NERC reliability standards, the facility adheres to stringent grid stability and safety protocols. The 138 kV voltage level is typical for sub-transmission and transmission applications, facilitating efficient power transfer over moderate distances. San Andres Substation contributes to the reliability of the local electrical infrastructure by ensuring voltage regulation and power flow management. Its location in Texas, a state with growing energy demand and significant renewable energy integration, underscores its importance in maintaining grid balance. The substation supports both residential and industrial consumers, reinforcing the resilience of the regional power system.
Environmental context
The substation is situated in Texas, a region characterized by hot summers and variable weather patterns, including occasional severe storms. Electrical infrastructure in this area must be designed to withstand high temperatures and extreme weather events. The 138 kV voltage level indicates a balance between transmission efficiency and environmental footprint, as higher voltages reduce line losses but require larger clearances. The facility's operation aligns with grid modernization efforts to integrate renewable energy sources, such as wind and solar, which are prevalent in Texas.
