In 2025, Ireland's data centers consumed 23% of the nation's total electricity, nearly matching the total usage of all residential homes combined.Summary
Data center electricity consumption in Ireland reached 23% of the national total in 2025, a significant rise from previous years. Despite government regulations and grid restrictions intended to curb this demand, consumption surged by 10% in a single year, driven largely by the global AI boom and the operations of major hyperscalers like Microsoft, AWS, Google, and Meta. Consequently, Ireland has implemented a new Large Energy Users Connection Policy requiring developers to provide on-site power generation and source renewable energy to manage future growth.
