Sutherland Springs Substation: 138 kV Electrical Substation in Texas, United States

Sutherland Springs Substation is an operational electrical substation located in Sutherland Springs, Texas, United States. Owned by CPS Energy, a major municipal utility, the facility operates at 138 kV, a common transmission voltage level that supports regional power distribution and grid reliability. The substation's 138 kV voltage level places it within the high-voltage transmission network, which is critical for efficient long-distance power transfer. In the United States, such facilities are subject to NERC reliability standards and FERC regulation, ensuring grid stability and compliance with mandatory reliability requirements. CPS Energy, as the owner and operator, adheres to these frameworks to maintain safe and reliable operations. As part of the Texas Interconnection, Sutherland Springs Substation contributes to the resilience of the local and regional electrical infrastructure. Its location in a rural area underscores its role in connecting remote generation sources to load centers, supporting community energy needs and economic activity. The substation's operational status ensures continued service to the surrounding area.

The substation's 138 kV voltage level indicates its role in the transmission grid, which can have environmental implications related to land use and electromagnetic fields. Located in a rural area of Texas, the facility likely occupies a relatively small footprint, minimizing habitat disruption. Modern substations often incorporate SF6-free or low-emission technologies to reduce greenhouse gas impacts.
