Overview
Blewett Substation is an operational electrical substation in Texas, United States, owned and operated by the Lower Colorado River Authority. It operates at 138 kV, serving as a key node in the regional transmission grid.
Blewett 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, classifying it as a medium-voltage substation within the transmission network. As part of the LCRA's infrastructure, it supports the reliable delivery of electricity across central Texas. The substation's technical specifications indicate a 138 kV voltage level, which is typical for sub-transmission and distribution substations that connect bulk power systems to local distribution networks. In the United States, such facilities operate under the regulatory oversight of the Federal Energy Regulatory Commission (FERC) for wholesale electricity markets and must comply with North American Electric Reliability Corporation (NERC) reliability standards to ensure grid stability. The LCRA, as a nonprofit utility, manages this asset as part of its broader mission to provide water and power services. Environmentally, the substation is situated in a region characterized by the Texas Hill Country, where grid infrastructure must be resilient to weather extremes such as heatwaves and occasional winter storms. The facility plays a critical role in maintaining voltage stability and power quality for surrounding communities, contributing to the overall reliability of the Texas Interconnection grid. Its operational status ensures continued support for local residential, commercial, and industrial electricity needs.
Environmental context
The substation is located in the Texas Hill Country, a region with hot summers and variable weather patterns. As a 138 kV facility, it is part of the transmission infrastructure that must withstand high temperatures and occasional winter storms, which can stress grid components. The surrounding area includes rural and suburban development, requiring the substation to balance reliability with environmental considerations such as land use and wildlife corridors.
