Peapod and Stop & Shop announced the opening of a 10,000-square-foot facility in Long Island, marking the fifth facility in the region, a move that company officials say will boost home delivery of groceries by 10 percent in the New York area, according to a press release.

Peapod says it is the nation's largest online grocer, operating in 24 U.S. markets in the northeast, mid-Atlantic and midwestern states and offers delivery and pickup through a mobile app. The companies are both units of Ahold Delhaize Co. Stop & Shop has more than 400 stores in the U.S., located mainly in Massachusetts, Connecticut, New Jersey, New York and Rhode Island.  

The facility in East Northport is part of a renovation of the Stop & Shop supermarket there. Other Long island facilities are located in Medford, South Setauket, Riverhead and Farmingdale, N.Y. 

Last year the grocery chain added Alexa skill capabilities to its grocery delivery business in order to allow Amazon smart speaker owners to order using voice control technology.
