Overview
Miller Creek Substation is an operational electrical substation in Texas, United States, owned and operated by the Lower Colorado River Authority. It operates at a voltage of 138 kV, serving the regional grid.
Miller Creek Substation is an operational electrical substation located in Texas, United States. Owned and operated by the Lower Colorado River Authority (LCRA), this facility plays a role in the state's electrical infrastructure. The substation operates at a voltage of 138 kV, which is typical for sub-transmission and distribution-level assets in the region. As part of the LCRA's network, Miller Creek Substation falls under the regulatory oversight of the Federal Energy Regulatory Commission (FERC) and adheres to North American Electric Reliability Corporation (NERC) reliability standards. In Texas, substations like this are critical for integrating renewable energy sources and managing load growth in the rapidly expanding ERCOT market. Environmentally, the substation supports the local community by providing reliable electricity to residential, commercial, and industrial customers. Its location in central Texas places it within a region prone to extreme weather events, such as heatwaves and winter storms, which underscores the importance of robust infrastructure for grid resilience. The LCRA's focus on water and power management further highlights the substation's role in supporting both energy and water supply systems.
Environmental context
Located in central Texas, Miller Creek Substation operates in a region characterized by hot summers and occasional winter storms, which can stress electrical infrastructure. The substation's 138 kV voltage level indicates it serves as a distribution or sub-transmission asset, likely supporting urban and rural communities. Its proximity to the Colorado River basin may involve coordination with water management operations, as the LCRA manages both water and power resources in the area.
