Investing.com -- Ireland’s data center sector faces a turning point as surging electricity demand collides with limited grid capacity, pushing operators toward distributed power that could ease constraints but risks deepening fossil fuel dependence. In 2024, data centers consumed 6,969 gigawatt hours of electricity, 22% of Ireland’s total metered use, up from 5% in 2015. Their demand grew 10% year on year, compared with 3% among other users. EirGrid projects usage could rise to 31% by 2030, while peak demand, which topped 6,024 megawatts for the first time in January 2025, is forecast to surpass 7,000 MW by 2034. Overall electricity consumption is expected to grow 45% between 2023 and 2034, driven largely by artificial intelligence and cloud workloads. The strain has slowed development. Bitpower warned in October 2024 that €8–10 billion in projects are at risk due to grid limits and planning delays. Hyperscalers including Microsoft, Amazon and Equinix have shifted GPU-heavy workloads to the Nordics, citing abundant renewable power and fewer bottlenecks. Amazon canceled a €300 million plan for an AI facility in Dublin in July 2025, while Eaton reported an 80% fall in Irish data center revenue in four years. To keep building, operators are turning to on-site and private infrastructure. More than €6.5 billion in stalled projects moved forward after the government approved private wires in July 2025, allowing direct links to renewables, batteries or gas. 3rd party Ad.

Microsoft has nearly 1 gigawatt of renewable agreements in Ireland and has reprogrammed backup batteries in Dublin to supply the grid during peaks. Amazon is using waste heat from a Tallaght site for district heating. But many projects lean on fossil fuels. Digital Realty is investing €100 million in a 9 MW gas plant for its Dublin campus after being denied grid access. Friends of the Earth Ireland reported dozens of data centers pursuing gas connections to bypass grid delays. The International Energy Agency projects fossil fuels will provide more than 50% of global data center power through 2030, even as renewables expand. Regulators have stepped in. A February 2025 framework from the Commission for Regulation of Utilities requires new centers to match their maximum import capacity with dispatchable on-site or nearby generation or storage, and to participate in the electricity market by 2026. Annual reporting on renewable use and emissions will be mandatory, and new Dublin connections will face tougher standards. The government’s April 2025 enterprise strategy reaffirmed the sector’s role but warned that islanded fossil fuel-powered facilities are not aligned with policy. Challenges persist. Land shortages constrain solar and storage, backup systems are built for resilience rather than grid support, and high costs make industrial turbines unattractive. Analysts warn gas is likely to remain the default stopgap, shifting reliability pressure from the grid to the gas system. Ireland’s tensions reflect a broader European trend. Ember projects data centers in less congested regions such as the Nordics and Southern Europe will grow nearly twice as fast as core hubs like Dublin, Frankfurt and Amsterdam by 2030. 3rd party Ad.

Whether distributed power proves a breakthrough or bottleneck will depend on how quickly renewable-backed models can scale. For now, it is buying time but leaving Ireland’s climate goals in question. Most investors will find it hard to answer that question with total confidence.
