Overview
Pembrook Substation is an operational electrical substation in Texas, United States, owned and operated by Sharyland Utilities. It operates at a voltage of 138 kV, serving as a key node in the regional transmission grid.
Pembrook Substation is an operational electrical substation located in Texas, United States, owned and operated by Sharyland Utilities. The facility operates at a voltage of 138 kV, which classifies it as a medium-voltage substation within the transmission network, supporting regional power distribution and grid stability. The substation's technical specifications indicate a voltage level of 138 kV, typical for sub-transmission or distribution substations that step down power from high-voltage transmission lines to lower voltages for local distribution. As part of the U.S. electrical infrastructure, it operates under the regulatory oversight of the Federal Energy Regulatory Commission (FERC) and adheres to North American Electric Reliability Corporation (NERC) reliability standards to ensure grid security and operational integrity. Located in a rural area of Texas, Pembrook Substation plays a critical role in delivering electricity to surrounding communities and industrial users. Its operation by Sharyland Utilities, a transmission and distribution utility, underscores its importance in maintaining reliable power supply in the region. The substation's integration into the broader ERCOT grid highlights its contribution to the state's energy resilience.
Environmental context
The substation is situated in a semi-arid region of West Texas, characterized by low rainfall and sparse vegetation. Electrical infrastructure in such environments must account for temperature extremes and dust, which can affect equipment performance. The facility's voltage level and rural location suggest it supports agricultural and residential loads, with minimal direct environmental impact beyond land use and electromagnetic fields.
