How much data center capacity Ireland has installed, how it compares with the rest of Europe, and what our trackers show about its sites, operators, deals and rules.
Ireland data center capacity at a glance
Ireland had about 1.4 GW of installed data center capacity (IT load) at the end of 2025, by our estimate. That is about 9% of the capacity in Europe and puts Ireland at number 11 of the 26 countries in our global model. Our Data Center Tracker holds 3 sites in Ireland run by 3 operators: 3 operational, 0 under construction and 0 planned. Our trackers also hold 0 verified deals and 8 government measures in force for the country.
Installed capacity is IT load, the power available to servers, storage and network. The country figure comes from the same model as the global and regional totals and is benchmarked against dated public figures. Site figures below are what each source states, often a campus’s full build-out, so they are not the same measure.
