DataCentres Ireland, now in its thirteenth year, is the country’s primary gathering for data center owners, operators, suppliers, and policymakers. Two days at the RDS in Dublin draw 100+ exhibitors and 2,000+ professionals across a free-to-attend exhibition and a multi-stream conference covering colocation, AI, power, cooling, sustainability, and regulatory frameworks.

Ireland matters out of proportion to its size. Dublin hosts one of Europe’s densest hyperscale clusters, and the country’s evolving stance on new-build connections — the interaction between EirGrid capacity, on-site generation, and grid injection — has become a reference case for how mature European markets handle data center load growth. What the Irish regulators decide tends to arrive elsewhere in Europe within a couple of years.

Attend if you operate in Ireland, supply the Irish market, finance European data-center assets, or want the clearest early read on how European grid-connection policy is heading. The conference’s Irish-operator panels are particularly direct about what’s working and what isn’t — much more useful than the rosier view of the same issues at larger continental shows.
