Overview
Cedar Hill Substation is an operational 138 kV electrical substation in Texas, owned and operated by the Lower Colorado River Authority. It plays a key role in regional grid stability.
Cedar Hill Substation is an operational electrical substation located in Texas, United States, owned and operated by the Lower Colorado River Authority (LCRA). Operating at 138 kV, it is classified as a medium-voltage substation, typical for distribution and sub-transmission networks that serve urban and industrial areas. The facility is part of the broader Texas Interconnection grid, which operates under the jurisdiction of the Electric Reliability Council of Texas (ERCOT). The substation's technical specifications indicate a voltage level of 138 kV, which is common for regional power distribution in the United States. As an LCRA asset, it supports the authority's mission to provide reliable electricity to central Texas. The facility is likely equipped with modern switchgear and protection systems, adhering to North American Electric Reliability Corporation (NERC) standards for grid reliability and security. Environmentally, the substation is situated in a region with a mix of urban and rural landscapes. Its operation contributes to the stability of the local grid, supporting residential, commercial, and industrial customers. The LCRA's focus on water and power management in the Colorado River basin adds a layer of environmental stewardship, ensuring that the substation's operations align with regional sustainability goals.
Environmental context
The substation is located in central Texas, an area characterized by hot summers and periodic drought conditions. Its 138 kV voltage level indicates a role in distributing power to local communities, potentially supporting water pumping and treatment facilities. The LCRA's integrated water and power management approach means the substation's reliability is critical for both energy and water security in the region.
