Overview
Lewis Creek Substation is an operational electrical substation in Texas, United States, operated by Entergy. It operates at a voltage of 138 kV, serving as a key node in the regional transmission grid.
Lewis Creek Substation is an operational electrical substation located in Texas, United States. Owned and operated by Entergy, the facility is part of the broader transmission infrastructure that supports the region's power distribution needs. With a voltage level of 138 kV, it is classified as a high-voltage substation, playing a critical role in stepping down transmission voltages for local distribution. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for the bulk power system. Entergy, as the operator, complies with these standards to ensure grid stability and security. The 138 kV voltage level is typical for sub-transmission systems in the United States, connecting larger transmission lines to distribution networks. Located in Texas, a state with a diverse energy mix including natural gas, wind, and solar, Lewis Creek Substation supports the integration of renewable energy sources into the grid. Its operational status ensures reliable electricity supply to surrounding communities and industrial users, contributing to the overall resilience of the regional electrical infrastructure.
Environmental context
The substation is situated in a region characterized by a mix of forested areas and urban development. High-voltage substations like this one can have localized environmental impacts, such as electromagnetic fields and land use changes. However, modern substations are designed with mitigation measures to minimize ecological disruption. The facility's role in grid stability supports the integration of renewable energy, indirectly contributing to reduced greenhouse gas emissions.
