Overview
Sinclair Hearne Substation is an operational electrical substation in Texas, United States, operated by Entergy. It operates at 69 kV, serving as a key node in the regional power grid.
Sinclair Hearne Substation is an operational electrical substation located in Texas, United States, and operated by Entergy. The facility operates at a voltage level of 69 kV, which classifies it as a medium-voltage substation typical for distribution and sub-transmission roles within the electrical infrastructure network. As part of the U.S. electrical grid, Sinclair Hearne Substation operates under the regulatory framework established by the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These bodies enforce reliability standards and ensure the stability of the bulk power system. The substation's equipment likely adheres to industry standards such as IEEE and ANSI, with modern switchgear and protection systems to maintain safe and reliable operation. The substation plays a critical role in local power distribution, stepping down voltage from transmission lines to serve residential, commercial, and industrial customers in the region. Its location in Texas, a state with a large and growing energy demand, underscores its importance in maintaining grid stability and supporting economic activity.
Environmental context
The substation is situated in a rural area of Texas, where the surrounding landscape is primarily agricultural. The facility's operation involves electromagnetic fields and potential oil leakage from transformers, which are managed through standard environmental safeguards. Its location away from dense urban centers reduces direct human exposure, but the substation's role in the grid means it supports energy-intensive activities that have broader environmental implications.
Frequently asked questions
