Irish planning body overturns permission for €1.5bn Mayo data centre

An Coimisiún Pleanála has overturned planning permission for a €1.5bn data centre in north Mayo, a decision the County Council's Chief Executive called 'very disappointing'. The project, opposed by author Sally Rooney, was set to be a major infrastructure investment in the region; the reversal introduces uncertainty over Ireland's data centre development pipeline and its energy grid implications.
