Overview
Hollmig Substation is an operational electrical substation in Texas, United States, owned by the Lower Colorado River Authority. It operates at 138 kV, serving as a key node in the regional transmission grid.
Hollmig Substation is an operational electrical substation located in Texas, United States, owned and operated by the Lower Colorado River Authority (LCRA). The facility operates at a voltage of 138 kV, placing it within the high-voltage transmission tier that supports bulk power transfer across the region. As a substation, it plays a critical role in stepping down voltage for distribution or interconnecting transmission lines. The substation's 138 kV voltage level aligns with typical sub-transmission infrastructure in the United States, which is regulated under NERC reliability standards and FERC oversight for grid stability. LCRA, a nonprofit utility, manages this asset as part of its broader mission to provide reliable electricity to central Texas. The facility's operational status indicates it is actively contributing to the regional power network. Environmentally, the substation's location in rural Texas minimizes direct impact on urban populations, though its role in the grid supports the integration of renewable energy sources like wind and solar from the surrounding area. Its continued operation underscores its importance to local energy resilience and the LCRA's transmission infrastructure.
Environmental context
The substation is situated in a rural area of Texas, where the local environment is characterized by open grasslands and agricultural land. Its 138 kV voltage level indicates it is part of the sub-transmission network, which typically has lower visual and electromagnetic field impacts compared to higher-voltage lines. The facility's operation supports grid stability in a region prone to extreme weather events, such as heatwaves and winter storms, which can stress electrical infrastructure.
