Europe has taken a significant step toward addressing the growing energy demands of artificial intelligence infrastructure by activating its first microgrid-connected data center near Dublin, Ireland.
The facility, located just outside the Irish capital, represents a new approach to powering large-scale computing operations. Instead of relying entirely on the national electricity grid, the data center operates through an independent or “islanded” microgrid, allowing it to generate and manage its own electricity supply.
The project is operated by AVK, a power supply solutions provider, in partnership with Pure Data Centre Group, a digital infrastructure developer. The two companies say the installation marks Europe’s first data center running on a live microgrid system.
The development comes as Europe seeks to capitalise on the global artificial intelligence boom while tackling long-standing challenges in electricity infrastructure.
The rapid expansion of AI and cloud computing is placing enormous pressure on energy systems worldwide. According to the European Commission, the European Union will require at least 1.2 trillion euros ($1.39 trillion) in investments by 2040 to modernise its electricity grid and meet rising demand.
In many cases, companies building data centers face long waiting periods to secure grid connections due to infrastructure bottlenecks that have persisted for decades.
As a result, some firms are increasingly exploring alternative energy solutions that allow them to operate independently from national grids.
Microgrids are localised energy networks capable of generating, storing and distributing electricity independently.
Unlike traditional energy systems that rely entirely on national grids, microgrids can function autonomously and maintain power supply even during grid disruptions.
Microgrids are already widely deployed in the United States, particularly in regions with high concentrations of data centers such as Texas and Virginia.
The rapid expansion of AI infrastructure in those areas has accelerated the adoption of off-grid or hybrid power solutions.
The Dublin facility represents a new model for powering large-scale digital infrastructure in Europe.
“As these data centers get bigger and we see AI workloads and that data becoming more of a feature in our day-to-day lives, that only puts more stress on the grid. So we have to drive to a different solution,” AVK CEO Ben Pritchard told a news agency.
The data center has a total capacity of about 110 megawatts, and the total projected investment in the site is about 1 billion euros ($1.2 billion).
It is designed to support both cloud computing services and artificial intelligence workloads, which require massive amounts of electricity for high-performance processing.
Ireland has been at the centre of Europe’s debate over the energy consumption of data centers.
The country is one of only two in Europe that have implemented a moratorium on new data center applications because of pressure on the national grid.
Data centers consumed 22% of Ireland’s electricity in 2024, highlighting the scale of the energy challenge.
Ireland’s national grid operator warned in late February that meeting electricity demand could be “challenging” as power usage patterns evolve.
In response to the AI boom, Irish authorities relaxed the moratorium last year but introduced strict new rules for data centers connecting to the grid.
New facilities must now:
Provide dispatchable power, meaning electricity that can be turned on or off depending on grid demand
Have energy storage capabilities
Source at least 80% of annual demand from renewable electricity generated in Ireland
These guidelines were issued by the country’s energy regulator Commission for Regulation of Utilities.
For companies waiting years for grid access, microgrids offer a practical alternative.
“The alternative in Ireland was to wait, literally wait for an unknown time to be able to get a grid connection, and still today you’re not able to get a grid connection. So creating a microgrid enabled us to move our project forward,” Pure DC President Dawn Childs told a news agency.
Childs said the system was designed both as an immediate workaround and a long-term infrastructure solution.
“If we have to stay as an islanded solution, we absolutely can ... However, to get the most sustainable solution and to provide services back into the grid in Dublin, in the most constrained area of Ireland, it would be our desire to get a grid connection.”
Currently, the data center is powered by natural gas engines with the capability to switch to Hydrotreated Vegetable Oil (HVO).
The facility has also conducted trials using biomethane as an alternative energy source.
If connected to the grid in the future, the site will be capable of providing up to 20 MW of battery storage and dispatchable electricity.
The global microgrid industry is expanding rapidly as companies seek reliable power solutions for critical infrastructure.
The market was valued at around $29 billion in 2025, and Europe’s microgrid market is expected to grow by nearly 10% per year due to aging grid infrastructure.
Technology companies and energy providers are increasingly investing in the sector.
Major industrial technology firms are actively working on microgrid solutions, including:
ABB
Siemens
Schneider Electric
Schneider Electric opened a microgrid testing laboratory in Massachusetts last year to evaluate the systems in real-world operating conditions.
Despite their potential benefits, microgrids face regulatory challenges in many regions.
“Making these assets grid participants in theory and in practice are very different questions,” said Diego Diaz Hernandez, partner at McKinsey & Company.
“Technically speaking, it’s very feasible to do so, and we’ve seen examples of that in the U.S. [where] grid operators are requiring 50 or even 100 hours of flexibility out of the entire year in order to ease the pressure on the grid. So they’re not asking for a lot, but actually having the regulation and policy in place to allow for that to happen is a big question.”
Microgrid adoption is still developing in Europe compared to the United States.
About 30% of U.S. data centers already use microgrid or other behind-the-meter power systems, such as gas turbines or fuel cells.
In Europe, the share was just 5–10% 18 months ago, but has already risen to about 20%.
According to AVK, a new type of investor is emerging in the sector.
“They’re infrastructure funds who are looking to build, own and operate microgrids and supply power to the data centers,” Pritchard said.
He expects this asset class to mature significantly over the next three to five years.
The launch of Europe’s first microgrid-connected data center marks an important milestone in the evolution of digital infrastructure. As artificial intelligence applications expand rapidly, the demand for reliable and scalable power sources is increasing across the world.
Microgrids offer a potential solution by allowing data centers to generate and manage their own electricity, reducing dependence on overstretched national grids. The Dublin project demonstrates how independent energy systems could support the next generation of AI and cloud computing facilities.
However, the long-term success of this model will depend on regulatory frameworks, sustainable energy sources and reliable technology deployment. If these challenges are addressed, microgrids could play a major role in powering the future of AI infrastructure while supporting global energy transition goals.
