Transmission Projects - Oakville to Alliance 230kV Transmission Line Project
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.
