DOVER — After months of rumors, the mystery grocer coming to the corner of Glenwood and Central avenues has been identified as Aldi supermarket.

“It’s officially official,” said Jim Mitchell, vice president of Hampton-based Tropic Star Development, which owns the property. “We’re very excited.”

The building has yet to be constructed, but Mitchell said the property would be turned over to Aldi next week and crews will begin to build the new store. Mitchell anticipates the 22,000-square-foot grocery store will open in late spring 2019.

The Newburyport Five Cent Savings Bank branch opened last month in front of where Aldi will be located. A Chipolte Mexican Grill is set to open there next month, Mitchell said. Firehouse Subs and Sports Clips Haircuts also will open locations at the new development. Mitchell said a 2,556-square-foot unit remains available at the site.

Aldi, a German-based chain, announced a $3.4 billion expansion plan last year with a goal of having 2,500 stores by the end of 2022, making it the third-largest grocery store chain in the country behind Walmart and Kroger. In New Hampshire, there are Aldi stores in Manchester, Concord, Salem, Derry, Plaistow, Nashua and Keene.

The new grocer will open across the street from the current location of Shaw’s and Hannaford supermarkets. That's in keeping the chain's plan, according to what Aldi U.S. CEO Jason Hart told CNBC in August. "We are going where competitors are, we like to be close to the competition for convenience reasons for our customer. We like them to shop exclusively Aldi, but we recognize that consumers are going to more than one store," he said.

Aldi states 90 percent of its products are brands exclusive to the store, and customers must deposit a quarter, which is refundable, to use grocery carts. The chain says both of these strategies help keep prices lower for consumers.
