Overview
Westheimer Substation, operated by CenterPoint Energy in Houston, Texas, is a key electrical infrastructure node with voltage levels of 138 kV, 34.5 kV, and 12.5 kV, supporting grid stability in the region.
Westheimer Substation is an operational electrical substation located in Houston, Texas, United States. Owned and operated by CenterPoint Energy, it plays a critical role in the regional power distribution network, serving the greater Houston metropolitan area. The facility is part of the larger transmission and distribution grid that ensures reliable electricity supply to residential, commercial, and industrial customers. The substation operates at multiple voltage levels: 138 kV for high-voltage transmission, and 34.5 kV and 12.5 kV for sub-transmission and distribution. This configuration allows it to step down power from the bulk transmission system to local distribution networks. As part of the US electrical infrastructure, it adheres to NERC reliability standards and FERC regulations, ensuring grid stability and security. The facility's urban location in Houston underscores its importance in meeting the high electricity demand of a major city. Westheimer Substation contributes to the resilience of the Texas Interconnection, which operates independently from the Eastern and Western Interconnections. Its strategic location supports the integration of distributed energy resources and helps maintain voltage stability in a region prone to extreme weather events. The substation's role in the CenterPoint Energy network is vital for the economic activity and daily life of millions of residents in the Houston area.
Environmental context
