Entergy to upgrade Derbigny substation

2022-9-15 Entergy

Entergy New Orleans has announced infrastructure upgrades at its Derbigny substation to help deliver reliable energy to more than 9,000 customers in the Central Business District of New Orleans.

While the company continues to identify and implement reliability projects across the Entergy New Orleans electric system, several specific upgrades have been made to the 300 MW Derbigny substation. Among these upgrades are new laser installations to deter birds, upgraded fencing to prevent further animal intrusions, additional passive animal mitigation, and multiple breaker replacements.

A new protection clearing scheme that identifies, reacts, and responds more rapidly if there is a fault or failure in the substation will also be completed by the end of the year. The operational flexibility and reliability of the substation greatly depends upon the protection scheme. The new upgrades will help mitigate the risk of outages and shorten power restoration times in the area.

“We continue to take a holistic view of how we plan infrastructure upgrades that will benefit the largest number of customers,” said Deanna Rodriguez, President and CEO of Entergy New Orleans. “This project is a perfect example of investing in a specific part of the grid with a high economic impact to the entire city.”

The substation contains three transformers for redundancy and is currently undergoing work on sectionalization, which will further isolate faults, protect equipment and minimize outage durations.

The Derbigny substation upgrades are among a number of investments in the grid across Orleans Parish including the Avenue C substation transformer replacement, the underground transformer replacement project in the Central Business District and French Quarter, and the New Orleans Power Station – which provides 128 MW of needed local generation and played a vital role in New Orleans’ recovery from Hurricane Ida.
