Entergy (NYSE:ETR) on Sept. 25 said that Entergy Louisiana has completed the Lake Charles Transmission Project, which included building two new substations and expanding two others, as well as adding about 25 miles of high-voltage transmission lines – 500-kV and 230-kV lines – to move power more efficiently into the fast-growing region.
Entergy Louisiana spokesperson Lee Sabatini on Sept. 27 told TransmissionHub that the project’s estimated total cost was about $187m, and that the project was completed and energized in August.
Sabatini noted that the new stations are the 500-kV Rhodes switching station and the 500/230-kV Patton substation, while the expanded substations are the 230-kV Carlyss substation and the 230-kV Solac substation. The new transmission lines are the Rhodes to Patton 500-kV Transmission Line, the Patton to Carlyss 230-kV Transmission Line, and the Carlyss to Solac 230-kV Transmission Line.
The company said that the project is one of three recent resiliency projects for Entergy Louisiana completed to date this year, with the two other projects being:
- The Oakville-Alliance transmission project, which included rebuilding and expanding the Oakville substation to build a 230-kV transmission path between one of Entergy Louisiana’s substations in Jefferson Parish and a substation in Plaquemines Parish. Sabatini noted that the project was completed and energized in March
- Entergy Louisiana’s portion of the Terrebonne to Bayou Vista transmission project, which is a collaborative effort between Entergy Louisiana and Cleco Power, LLC to improve reliability in southeast Louisiana. Entergy Louisiana completed its 24-mile section of the 36-mile line in May, while Cleco is working to complete its section
“The Lake Charles Transmission Project, one part of a multi-phased resiliency project, is essential to meeting today’s power demands and keep pace with Louisiana’s economic growth,” Phillip May, president and CEO of Entergy Louisiana, said in the statement, in part. “Our investments will enhance reliability, improve efficiency across the state and expand our load serving capability throughout South West Louisiana.”
Entergy said that Entergy Louisiana is more than halfway through its plans to invest about $465m in transmission expansion and upgrade projects this year to strengthen and enhance the reliability of its energy grid. Upgrades include structures and rebuilt lines that are designed to withstand a category four hurricane, the company noted.
