Overview
Lewis Creek 230 kV Substation is an operational electrical substation in Texas, United States, operated by Entergy. It handles voltages of 230 kV and 138 kV, serving as a key node in the regional transmission grid.
Lewis Creek 230 kV Substation is an operational electrical substation located in Texas, United States. Owned and operated by Entergy, a major utility in the region, the substation handles transmission voltages of 230 kV and 138 kV, indicating its role in high-voltage power distribution and grid stability. 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 bulk power systems. As a 230 kV facility, it is classified as a transmission-level asset, critical for interconnecting generation sources with load centers. The presence of dual voltage levels (230 kV and 138 kV) suggests it serves as a step-down or switching station, facilitating power flow between different voltage tiers. Located in Texas, the substation supports the Electric Reliability Council of Texas (ERCOT) grid, which manages approximately 90% of the state's electric load. The facility's operational status and voltage capacity underscore its importance in maintaining grid reliability and meeting the energy demands of the surrounding region. Its location in a state with significant industrial and residential growth highlights its role in supporting economic activity and community services.
Environmental context
The substation is situated in a region characterized by a humid subtropical climate, with hot summers and mild winters. The surrounding area includes mixed forest and agricultural land, with proximity to the Sam Houston National Forest. The facility's high-voltage equipment is designed to withstand local weather extremes, including thunderstorms and occasional hurricanes. The substation's location in a rural-urban interface minimizes direct environmental impact while supporting grid connectivity for residential and industrial users.
