Entergy Louisiana strengthens the grid with completion of transmission upgrades in Metairie

02/10/2025

METAIRIE, La. – Entergy Louisiana has completed critical upgrades to its transmission infrastructure in Metairie as part of its resilience plan. The project marks the beginning of the transmission portion of the company’s resiliency program by replacing wooden transmission structures inside a major Jefferson Parish substation with single-pole steel structures rated for 150 mph wind speeds.

These enhancements are designed to improve the strength and resiliency of the transmission system, reducing the likelihood of service interruptions and aligning with Entergy’s broader efforts to modernize Louisiana’s electric grid.

“These infrastructure upgrades are a key part of our resilience strategy, ensuring we continue to provide reliable power to our customers,” said Phillip May, president and CEO of Entergy Louisiana. “By modernizing our grid and investing in stronger materials, we’re building a more robust electric system that will serve Louisiana communities for years to come.”

This project is one of many infrastructure improvements underway as part of Phase I of Entergy Louisiana’s recently approved resilience program. The company’s resilience plan focuses on reinforcing critical transmission and distribution structures across the state.

Over the next four years, Entergy Louisiana’s resilience plan will fortify electric infrastructure statewide, strengthening the power grid and safeguarding Louisiana’s economy. The initial phase includes 2,100 projects targeting 69,000 distribution and transmission structures. Upgrades include replacing electric equipment, such as poles, guy wires, anchors and power lines, to meet modern wind-loading standards.

Construction on the Metairie-based project began in January as crews installed the drill pier foundation followed by the installation of the new steel transmission poles. With these upgrades now complete, the transmission line is better equipped to support resilient electric service for customers in the Metairie area.

With this latest project completed, Entergy Louisiana remains focused on delivering long-term system enhancements that provide the best value to customers. Through strategic investments in grid resilience, the company is strengthening Louisiana’s electric infrastructure and ensuring continued reliability across its service territory.
