Ireland just told its data center industry to stop freeloading off the national grid. The country’s new “Bring Your Own Power” policy requires incoming facilities to either generate their own electricity on-site or lock in contracts with renewable energy producers, a move that fundamentally reshapes how one of Europe’s biggest data center hubs operates.
Here’s the thing: data centers in Ireland now account for roughly 21% of the country’s total electricity consumption. The Commission for Regulation of Utilities (CRU) issued the decision paper codifying this policy in December 2025, with a compliance deadline of March 2026.
What the policy actually requires
The BYOP framework has teeth. New data centers must secure on-site generation or storage capacity that matches their import capacity from the grid.
But it goes further than just self-sufficiency. Facilities must source at least 80% of their electricity from renewable sources.
