Overview
Jeanetta Substation is an operational electrical substation in Houston, Texas, owned and operated by CenterPoint Energy. It handles voltages of 345 kV, 138 kV, and 12.5 kV, serving the regional grid.
Jeanetta Substation is a key electrical infrastructure facility located in Houston, Texas, United States. Owned and operated by CenterPoint Energy, the substation plays a critical role in the regional power distribution network, stepping down high transmission voltages to lower distribution levels for residential and commercial customers. The substation operates with multiple voltage levels: 345 kV for high-voltage transmission, 138 kV for sub-transmission, and 12.5 kV for local distribution. This configuration is typical for major substations in the US, where NERC reliability standards and FERC regulations govern grid stability and interconnection requirements. CenterPoint Energy, a major utility in the region, manages the facility as part of its extensive transmission and distribution system serving the Houston metropolitan area. As part of the Texas Interconnection, Jeanetta Substation contributes to the reliability of the ERCOT grid, which operates independently from the Eastern and Western interconnections. The substation's urban location in Houston underscores its importance in supporting the city's high electricity demand, particularly during peak summer months. Its operational status ensures continued service to the surrounding community, facilitating economic activity and daily life.
