Construction began on March 1 on an Entergy Louisiana 230-kV line

Construction began on March 1, as planned, on the SELA Project Phase 3, Oakville-Alliance 230-kV Transmission Line in Louisiana, an Entergy (NYSE:ETR) spokesperson told TransmissionHub on March 2.

According to Entergy, the $60m project will improve service reliability for Plaquemines Parish residents, and help meet the power needs of the area’s growing economy.

Entergy’s Entergy Louisiana is building the 10.5-mile line between the Oakville substation, off Walker Road in Belle Chasse, and the Alliance substation, just west of Louisiana Highway 23, near the Phillips 66 refinery, Entergy added in its Feb. 23 statement.

About nine miles of the new line will be built along Louisiana Highway 23, and as the project progresses, it will require the periodic closing of the outer southbound lane of the highway, the company said. Entergy Louisiana will coordinate with the Plaquemines Parish Sheriff’s Office and the Louisiana Department of Transportation and Development to limit the project’s impact on traffic along Highway 23, the company said.

Work on the project is being coordinated with the replacement of more than three miles of parish water line along Highway 23, the company said, noting that several sections of the water line are being replaced with new piping closer to the highway shoulder to allow for the construction of the new transmission line. Entergy Louisiana is paying for the work, which should be complete by July, as part of the transmission project, Entergy added.

Depending upon weather and other variables, the project should be complete between mid-December and mid-February 2018, the company said.

The project is the third one of a program to enhance service reliability to Plaquemines Parish customers and help meet the needs of the parish’s growing business sector, the company said.

The first project involved expanding the Peters Road substation to supply the new 230-kV line, and the second project included rebuilding and expanding the Oakville substation, as well as building the new 6.4-mile, 230-kV Peters Road-Oakville transmission line between the Peters Road and Oakville substations.

The Peters Road-Oakville line was placed in service on Sept. 1, 2012, the spokesperson said. Work on both the Peters Road and Oakville substations was completed in the 2012-2013 timeframe, he said.

The latest project included improvements to the Alliance and Oakville substations completed about four years ago, Entergy said.
