Transmission Projects - Oakville to Alliance 230kV Transmission Line Project

Project Description

The Oakville-Alliance transmission project is the third part of a multi-million dollar program to enhance the reliability of service to Plaquemines Parish customers and meet the needs of a growing economy.

The overall program involves a series of projects to build a 230 kV transmission path between the Peters Road substation in Jefferson Parish and the Alliance substation. The first project involved expanding the Peters Road substation to supply the new 230 kV line. The second project involved rebuilding the Oakville substation to serve as a new 230/14kV distribution substation and constructing a new 230 kV transmission line between the Peters Road and Oakville substations.

The third project includes constructing a 10.5-mile 230 kV transmission line between the Oakville substation, which is off Walker Road in Belle Chasse, and the Alliance substation, located west of Louisiana Highway 23 near the BP-Alliance refinery. Surveying and engineering work is in progress, and permitting and right-of-way acquisition are underway. Line construction is expected to begin in mid-2017 and be complete by summer 2018. The third project also included work at the Alliance substation (expand and install a 230/115 kV autotransformer) and Oakville substation (expand and install a new line bay), which was completed in the 2012-13 timeframe.
