Ireland’s Central Statistics Office (CSO) reports that data centres account for a growing share of electricity use. In 2025, data centres consume 23% of total metered electricity consumption, up from 22% in 2024. The CSO data also show a long-term increase: data centres used just 5% of metered electricity consumption in 2015, indicating a steady rise over the past decade. A separate report citing the CSO figures states that data-centre electricity consumption is up by 10%, aligning with the higher share recorded in 2025. Together, the sources indicate both an increase in the proportion of electricity demand attributable to data centres and growth in overall usage from the prior period. The reporting focuses on metered electricity consumption and the change in data centres’ share of that total, rather than on broader electricity generation or consumption trends. No additional breakdown by region, customer type, or energy source is provided in the cited summaries.
