Entergy New Orleans crews have finished the first phase of upgrades to the city’s electric power transmission system in the Audubon Park, upper Magazine Street and Annunciation Street neighborhoods and will soon begin work in Carrollton and Hollygrove, the utility said Monday.

Entergy plans to begin the next phase of the project Oct. 5 and finish by March 2016.

The utility has scheduled three community meetings to discuss the work. The meetings are slated to run from 6 p.m. to 7:30 p.m. on Sept. 22 at Central St. Matthew United Church of Christ, 1333 S. Carrollton Ave.; Sept. 23 at Total Community Action, 1416 S. Jefferson Davis Parkway; and Sept. 24 at the Xavier University Convocation Center Annex, Room 111, 7800 Washington Ave.

Utility crews will use large equipment in those neighborhoods, and traffic in some areas may be blocked for several hours along various transmission poles. The upgrades are part of a $30 million capital investment as Entergy prepares to retire its aging Michoud power plant by next year. The facility has been in service since the 1960s.

Residents and customers in the affected areas will receive information about the transmission line replacement procedure and how it will affect them.

The Power to Grow NOLA website will provide details. Customers may voice specific questions and concerns through a hot line at (504) 670-3624 or by emailing powertogrownola@entergy.com.
