Overview
Elmendorf Substation is an operational electrical substation in Texas, United States, owned and operated by CPS Energy. It operates at 138 kV, serving the local grid.
Elmendorf Substation is an operational electrical substation located in Texas, United States. Owned and operated by CPS Energy, the facility plays a role in the regional power distribution network. 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 U.S. electrical grid, Elmendorf Substation operates under the regulatory framework established by the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These bodies enforce reliability standards for transmission and distribution assets. The substation likely includes switchgear and transformers to step down voltage for local distribution, adhering to standards such as IEEE C37 for substation equipment. The substation's location in Texas places it within the Electric Reliability Council of Texas (ERCOT) interconnection, which manages the state's power grid. CPS Energy, the owner and operator, is a municipal utility serving San Antonio and surrounding areas. The facility contributes to grid stability and supports residential, commercial, and industrial customers in the region.
Environmental context
The substation is situated in a region with a semi-arid climate, where extreme heat events can increase electricity demand for cooling. Its urban-proximate location near San Antonio means it supports a dense population center. The 138 kV voltage level indicates it is a critical node for distributing power from transmission lines to local feeders, and its age and equipment condition are typical for a facility of its type in the area.
