Overview
Kerrville Legion Substation is an operational 138 kV substation in Kerrville, Texas, owned and operated by the Lower Colorado River Authority, serving the regional electrical grid.
Kerrville Legion Substation is a 138 kV electrical substation located in Kerrville, Texas, United States. It is owned and operated by the Lower Colorado River Authority (LCRA), a nonprofit public utility that provides electricity, water, and community services across Central Texas. The substation plays a key role in the transmission and distribution of power within the LCRA's service area. The substation operates at 138 kilovolts, a standard transmission voltage level in the United States, and is part of the broader ERCOT (Electric Reliability Council of Texas) grid. As a transmission-level asset, it is subject to NERC reliability standards and FERC regulation, ensuring grid stability and compliance with federal and state requirements. The facility's equipment includes modern switchgear and transformers typical of mid-voltage substations. Located in the Texas Hill Country, the substation supports the growing energy demands of Kerrville and surrounding communities. Its operation is critical for maintaining reliable power supply to residential, commercial, and industrial customers. The LCRA's integrated water and power management approach also ties the substation's role to regional environmental stewardship, including drought management and conservation efforts.
Environmental context
The substation is situated in the Texas Hill Country, a region characterized by limestone geology, oak-juniper woodlands, and the Guadalupe River watershed. The area's semi-arid climate and periodic drought conditions influence energy demand patterns, particularly for water pumping and air conditioning. The substation's location in a mixed urban-rural setting requires careful management of electromagnetic fields and vegetation clearance to minimize wildfire risk and habitat disruption. Its operation supports the integration of renewable energy sources, such as wind and solar, which are increasingly part of the ERCOT grid mix.
