As Barry moved ashore the Louisiana coast on July 13, Entergy and Cleco, the two major electricity companies in southern Louisiana, reported the loss of power to over 114,000 customers. Power lines knocked down by fallen trees in the Metairie area cut power to 5,140 electricity customers in the New Orleans metropolitan area. The most widespread power outages occurred where wind speeds were highest in Lafourche Parish and Terrebonne Parish, as well as eastern Baton Rouge; over 39,000 lost power in these areas. All electricity customers in Grand Isle lost power, and a total of 4,300 customers were affected by power outages as Barry's initial rainbands swept across coastal Louisiana.
