Ninemile West Bank Transmission Project

Transmission line upgrades continue on the West Bank of Jefferson Parish. Crews have completed the Westwego and Harvey portions of the project and have started work to rebuild the line to the Barataria substation.

We will continue to update this page with important and timely project information. For questions or concerns, customers are encouraged to call the Power to Grow Louisiana hotline at 504-365-2973 or email

The West Bank of Jefferson Parish will be positioned for continued economic growth and enhanced weather readiness when Entergy Louisiana completes a three-phase technological upgrade to its electric power transmission system.

The project will enhance reliability, increase transmission capacity and help ensure the availability of affordable power now and into the future. The overall initiative consists of three separate projects.

The maps below outline the areas affected by the projects. The colored lines indicate the path along which the existing electric transmission lines will be upgraded.

What is the project's timeframe?

Preliminary work on the projects began in June 2017. Work affecting residents and businesses is scheduled to be complete by mid-2018.

Should I be concerned about safety issues?

Our top priority is to have a safe, accident-free environment. Entergy Louisiana has developed detailed on-site safety measures that have been tailored to meet the needs of the project, community and impacted areas.

When will the crews be working?

Crews will work primarily from dawn to dusk, approximately 10-12 hours per day.

How will my neighborhood be impacted?

When construction is taking place in your neighborhood, there will be revolving street closures, no parking zones, as well as pedestrian and bicycle restrictions.

Will my neighborhood lose power?

We have currently identified a few locations that will require brief service interruptions as a result of this project. For those affected customers, we will provide you with advance notice so that the appropriate accommodations can be arranged.

How long will crews be working on my block?

The duration of work on your block will vary depending on the distance between the existing poles in that section of the project. Entergy has developed a detailed communication plan to keep you informed before the crews reach your neighborhood. We will provide you with specific information to ensure you have the best information in a timely manner.

What about the trees and other vegetation?

Entergy Louisiana will work closely with local city and parish departments to ensure trees are trimmed in such a way to protect their health while still maintaining reliability -- something we already do as part of our annual proactive maintenance plan. As always, safety is our top priority. We will trim or remove trees that are too close to power lines to eliminate hazards, reduce outages and help ensure the safety of the public and crews.

How will I know if my street or block will be directly impacted?

If there is a large transmission pole located on your street, you will be impacted. Advance notification will be made through a variety of channels including local and social media and direct calls. Additionally, Entergy Louisiana customer service representatives will be providing information to residents and business owners to ensure that everyone is informed of the project construction work zones and timelines. Be on the lookout for Entergy Louisiana representatives in your neighborhood.
