The investment is expected to create 400 jobs
Discount retail giant Aldi is to open 20 new stores nationwide over the next three years.
The €100 million investment looks set to create 400 new jobs.
Aldi has 11.3% of Ireland's intensely competitive grocery market, according to the latest figures from researchers Kantar Worldpanel. It's the fifth largest supermarket - 0.1 percentage points behind rival Lidl.
"Our business model is pretty simple", head of Aldi's Irish operations Giles Hurley told The Sunday Independent.
The stores will be opened in Trim in Co Meath, Leixlip in Co Kildare and Ennistymon in Co Clare. It is currently looking to secure planning for outlets in Dunshaughlin in Co Meath and Graiguenamanagh, Co Kilkenny.
Aldi currently employs an estimated 3,200 people in the Republic of Ireland.
"There is, I would say a big opportunity in the big metropolitan areas of Dublin, Limerick, Galway, Cork where we feel there's lots of customers who can't easily access one of our stores," Mr Hurley added.
