Europe’s First Microgrid-Powered Data Centre Launches in Dublin

Dublin, Ireland – A recent data centre in west Dublin is now operational, marking a significant milestone as the first in Europe to run entirely off-site, independent of the national electricity grid. The facility, operated by Pure Data Centres Group, utilizes a 110 MW on-site microgrid developed in partnership with AVK, a leading provider of power solutions for data centres and AI infrastructure. Pure DC and AVK announced the launch on March 11, 2026.

Addressing Ireland’s Data Centre Energy Demand

Ireland has seen a dramatic increase in electricity consumption from data centres, rising from 5% in 2015 to 22% in 2024. According to RTÉ, this trend is projected to reach nearly a third of the nation’s total electricity demand by 2030. The new microgrid aims to alleviate pressure on the national grid and provide a resilient power source for data centre operations, particularly during initial development phases before full grid connection is established.

How the Microgrid Works

The microgrid currently relies on natural gas for fuel, but is designed to accommodate more sustainable alternatives such as biomethane and hydrotreated vegetable oil (HVO). As stated by Pure Data Centre’s Executive Chairman and interim CEO, Gary Wojtaszek, the system is “self-generated” and relies on its own power generation and fuel. The 110 MW capacity is equivalent to powering approximately 100,000 homes.

A Blueprint for European Expansion

AVK CEO Ben Pritchard highlighted that while microgrids are common in the US, this Dublin facility represents the first such deployment in Europe. The companies envision replicating this model across Europe, with Germany, the Netherlands, and the UK identified as key target markets. The project demonstrates how on-site energy infrastructure can complement national energy planning frameworks, particularly in regions undergoing phased grid reinforcement and renewable energy development.

Concerns and Future Plans

Despite the innovative approach, the reliance on natural gas has drawn criticism from environmental groups. Friends of the Earth Ireland CEO, Deirdre Duffy, expressed concerns about “fossil fuel lock-in” and the potential for increased energy costs and security risks due to geopolitical factors.

The Irish government recently published a Large Energy Action Plan and lifted a moratorium on new data centre connections, allowing construction where at least 80% of annual energy demand is met through new renewable sources.

Key Takeaways

• Europe’s first microgrid-powered data centre is now operational in Dublin, Ireland.
• The facility, operated by Pure Data Centres Group and developed with AVK, has a capacity of 110 MW.
• The microgrid currently uses natural gas but is designed to integrate sustainable fuel sources.
• The project aims to address Ireland’s growing data centre energy demand and provide a resilient power supply.
• Environmental concerns remain regarding the reliance on fossil fuels.
