The rapid expansion of artificial intelligence is creating an enormous demand for computing power—and electricity. A new data center project near Dublin has demonstrated a novel solution by running on its own private microgrid, rather than relying entirely on the national power network. The facility was developed by AVK in partnership with Pure Data Centres Group, marking one of the first examples in Europe of a large AI-focused data center operating with its own localized energy system.
The project highlights a growing challenge facing the AI industry: energy supply. Training and running large AI models requires massive computing infrastructure, and many countries’ electricity grids are struggling to keep up with the sudden surge in demand. In Ireland, for example, data centers already consumed about 22% of the country’s electricity in 2024, putting significant pressure on the national grid and slowing approvals for new facilities.
To overcome these limitations, the Dublin facility uses a microgrid—a localized energy system that can generate and distribute electricity independently of the main grid. The site currently has a capacity of around 110 megawatts, powered mainly by natural-gas engines that can also run on cleaner fuels such as hydrotreated vegetable oil. The system could later integrate renewable energy and battery storage, and potentially supply energy back to the grid if connected in the future.
Experts say this model may become increasingly common as the global AI race accelerates. Instead of waiting years for grid upgrades, companies may build self-sufficient power infrastructure to support data-center growth. While microgrids could help solve energy bottlenecks, they also raise questions about sustainability, regulation, and how to balance massive AI energy needs with climate and electricity-supply goals.
