Stonegate Substation - 138 kV Electrical Substation in Texas, United States

Stonegate Substation is an operational electrical substation located in Texas, United States. Owned and operated by CPS Energy, a municipal utility serving the San Antonio area, this facility plays a key role in regional power distribution. The substation operates at a voltage of 138 kV, which is a common transmission-level voltage in the US, indicating its importance in stepping down power for local distribution. As part of the US electrical infrastructure, Stonegate Substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These bodies enforce reliability standards for transmission assets, ensuring grid stability. The substation likely employs modern switchgear and automation systems, though specific technical details are not publicly listed. The substation's location in Texas, a state with a large and growing population, underscores its role in supporting residential and commercial electricity demand. CPS Energy's ownership ties the facility to a broader network serving over 800,000 customers. The operational status and voltage level suggest it is a critical node in the local grid, contributing to reliable power supply in the region.

The substation is situated in a suburban area of Texas, where land use is a mix of residential and commercial developments. Electrical infrastructure like this typically has minimal direct environmental impact, but its operation supports energy distribution that can influence local air quality through power generation sources. The facility's voltage level and urban location highlight its role in grid stability, which is essential for integrating renewable energy sources and reducing transmission losses.
