In short: since December 2025, new data centers connecting in Ireland must provide dispatchable generation or storage, onsite or nearby, matching their maximum import capacity and participating in the wholesale market, and source at least 80% of annual demand from additional Irish renewable projects.
Generation: dispatchable onsite or proximate generation and/or storage matching import capacity
Renewables: at least 80% of annual demand from additional Irish renewables
Scope: applies to data center applications submitted after 12 December 2025
Context: data centers use more than a fifth of Ireland's electricity
FROM DE FACTO MORATORIUM TO CONDITIONAL ACCESS
After years of restricted connections around Dublin, the regulator chose conditions rather than a ban. The policy applies specifically to data centers, recognising their large, flat and fast-ramping demand, and scales obligations by import capacity. Smaller sites must provide autoproducer capacity, larger ones dispatchable generation or storage.
WHAT IT MEANS FOR DEVELOPERS
An Irish data center becomes in part an energy project: generation or storage, market participation and renewable procurement all come with the connection. That raises capex and complexity, but gives a clearer route to connection than the previous restrictions.
WHAT IT MEANS FOR LENDERS
Lenders need to assess the generation asset and renewable contracts alongside the data center itself, including fuel, market revenues and emissions exposure. See how Ireland compares with the UK, Germany and France and the grid data center hub.
FREQUENTLY ASKED QUESTIONS
What does Ireland require from new data centers connecting to the grid?
Dispatchable onsite or nearby generation and/or storage matching the site's maximum import capacity, participating in the wholesale market, plus at least 80% of annual demand from additional Irish renewable projects.
When did Ireland's new data centre connection policy start?
It was published by the CRU on 12 December 2025 and applies to data centre connection applications submitted after that date.
Is there still a moratorium on data centers in Dublin?
The regulator chose conditional access rather than a ban: connections are possible if the new requirements on generation and renewables are met.
