Overview
Silver City Substation is an operational electrical substation in Texas, United States, owned and operated by Brazos Electric. It operates at 69 kV, serving as a key node in the regional power grid.
Silver City Substation is an operational electrical substation located in Texas, United States, owned and operated by Brazos Electric. The facility operates at a voltage of 69 kV, classifying it as a medium-voltage substation that plays a role in distributing electricity within the local grid. As part of the Brazos Electric cooperative network, it supports the delivery of power to member utilities and their customers. The substation falls under the regulatory oversight of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for the bulk power system. In Texas, the Electric Reliability Council of Texas (ERCOT) manages the grid, and substations like Silver City must comply with NERC's Critical Infrastructure Protection (CIP) standards to ensure cybersecurity and physical security. The 69 kV voltage level is typical for sub-transmission and distribution substations, often serving as a link between higher-voltage transmission lines and lower-voltage distribution networks. Operationally, Silver City Substation contributes to the stability and reliability of the regional power supply. Its location in central Texas places it within a region experiencing growing energy demand due to population and industrial expansion. The substation's role in voltage regulation and power distribution is critical for maintaining grid resilience, especially during peak load periods or extreme weather events common in the area.
Environmental context
The substation is situated in a rural area of central Texas, characterized by agricultural land and scattered communities. The local environment is subject to hot summers and occasional severe storms, which can impact grid reliability. Substations like Silver City are designed with weather-resistant equipment and may include vegetation management practices to reduce wildfire risk. The facility's operation involves minimal direct environmental impact, though its role in power distribution supports the broader energy system.
Frequently asked questions
Silver City Substation is located in Texas, United States, near coordinates 30.916885, -96.927593. It is operated by Brazos Electric.
Silver City Substation operates at 69 kV (69,000 volts), which is a medium-voltage level commonly used for sub-transmission and distribution in the US power grid.
Silver City Substation is owned and operated by Brazos Electric, a generation and transmission cooperative serving member utilities in Texas.
Substations in the US must comply with NERC reliability standards and FERC regulations. In Texas, they also follow ERCOT grid requirements, including NERC CIP standards for security.
A 69 kV substation typically steps down voltage from higher transmission lines (e.g., 138 kV or 230 kV) to distribution levels, or interconnects sub-transmission networks. It helps regulate voltage and ensure reliable power delivery to local communities.
