Tesco Ireland has said it will spend around €50 million this year on store upgrades, maintenance, and new openings.
In Dublin, it said two new Tesco Express stores recently opened in Spencer Dock and South Lotts Road, with two further Tesco Express stores opening in Smithfield and Charlemont Square before the end of the year.
Tesco also opened its new 11,000 sq ft store at White Pines in Rathfarnham in February.
It said a similar size store will also open its doors at Adamstown in West Dublin later this year.
In addition, a major refurbishment and extension of Tesco’s Artane Castle store has been completed.
Separately, the retailer said a rebrand and redesign programme is getting underway with Tesco's recently acquired portfolio of nine stores across Galway city and county owned by the Joyce family, which was completed in June.
It said a refit programme of older stores is also continuing across the country.
Tesco Ireland now has 154 shops across the country and employs over 13,000 people.
"We anticipate these new store openings and with the addition of Joyce's supermarkets in Galway, we will bring our overall number of stores to 165 this year, which is really good news for our colleagues, customers and the communities in which we operate," said Natasha Adams, Tesco Ireland CEO.
"We are continuously expanding and maintaining our estates and we are adding new employment with every store opening," she added.
