Overview
Kempner Substation is an operational electrical substation in Texas, United States, owned and operated by Brazos Electric. It operates at 138 kV, serving as a key node in the regional power grid.
Kempner Substation is an operational electrical substation located in Texas, United States. Owned and operated by Brazos Electric, the facility is a medium-voltage substation operating at 138 kV, which is typical for sub-transmission and distribution-level infrastructure in the region. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Electric Reliability Council of Texas (ERCOT), which sets reliability standards for the Texas Interconnection. As part of Brazos Electric's network, it supports the integration of generation resources and delivery of power to local distribution utilities. This facility plays a critical role in maintaining grid stability and reliability for the surrounding area. Its operational status and voltage level indicate it is an active component of the regional electrical infrastructure, contributing to the resilience of the Texas power grid.
Environmental context
The substation is located in a rural area of central Texas, where the local environment is characterized by grasslands and agricultural land. Electrical infrastructure in such settings typically has minimal direct environmental impact, though it supports the transmission of power from generation sources to load centers. The 138 kV voltage level is common for sub-transmission lines that connect to distribution networks, and the facility's design likely includes standard environmental mitigation measures such as oil containment for transformers.
Frequently asked questions
Kempner Substation is located in Texas, United States, near the city of Kempner in Lampasas County. Its approximate coordinates are 31.091341 N, -98.053976 W.
Kempner Substation operates at a voltage of 138 kV (138,000 volts), which is a common voltage level for sub-transmission and distribution substations in the United States.
Kempner Substation is owned and operated by Brazos Electric, a generation and transmission cooperative serving member utilities in Texas.
As part of the Texas Interconnection, Kempner Substation must comply with reliability standards set by the North American Electric Reliability Corporation (NERC) and the Electric Reliability Council of Texas (ERCOT). These standards cover grid stability, maintenance, and cybersecurity.
A 138 kV substation typically serves as a sub-transmission node, stepping down voltage from higher transmission levels (e.g., 345 kV) to distribution levels (e.g., 69 kV or lower). It helps route power to local distribution networks and industrial customers.
