Europe’s first data center powered by a microgrid has started operating in Ireland. This marks a new way to support artificial intelligence infrastructure as electricity use from AI computing keeps rising.
AVK, a Danish energy company, and Pure Data Centres, a global developer, partnered to launch the facility. The project aims to ease the pressure AI puts on national power grids and help new data centers open more quickly.
AI systems need a lot of computing power, so data centers are now among the fastest-growing users of electricity worldwide. The new Irish facility uses a microgrid, so it can make and manage its own electricity instead of depending only on the public grid.
Ireland’s grid constraints drive innovation
Ireland is now a key location for European data centers, as many global tech companies run their cloud services there. But limits on energy supply have started to slow down new projects.
TechBuzz reported that Ireland’s grid operator EirGrid introduced restrictions on new data center connections in the Dublin region in 2021 due to concerns about electricity demand exceeding supply.
Because of these limits, tech companies and developers are looking for new ways to power large computing sites. Microgrid systems, which use several power sources and can run on their own, are now being considered as a solution.
The new Irish data center is one of the first in Europe to try this approach on a large scale for AI infrastructure.
A €1 billion investment to support AI growth
This project is a big investment in new computing infrastructure. According to CNBC, about €1 billion (or $1.2 billion) has been invested, and the facility is built to handle large AI workloads.
The site has about 110 megawatts of capacity, which is enough to support the powerful computing clusters needed to train advanced AI models.
Ben Pritchard, CEO of AVK, said that as AI computing grows, new ways to supply power are needed. He told reporters the industry must find “different solutions” since traditional power networks cannot always meet the huge demand from today’s data centers.
AI computing driving massive power consumption
As AI technology grows quickly, electricity use in data centers is rising sharply.
One AI training cluster can use 10 to 20 megawatts of electricity, which is about as much as a small town uses.
TechBuzz also said that new traditional data centers can be delayed for three to five years while waiting for grid upgrades or new connections. In comparison, privately powered centers with microgrids could be up and running in 18 to 24 months, depending on permits and construction.
Because of these faster timelines, microgrid systems are becoming more appealing to companies trying to build AI infrastructure quickly.
Private power systems combine multiple energy sources
The Irish microgrid-powered facility uses a combination of distributed energy technologies to generate electricity independently.
The system combines solar power, natural gas, and battery storage. This lets operators balance different energy sources and keep a steady power supply for the computers.
AVK supplies the control systems that switch between these energy sources. These controls help keep operations stable, even if workloads change or renewable energy levels go up and down.
The ability to maintain uninterrupted power is especially critical for AI training operations, which can run for weeks and rely on thousands of GPUs working simultaneously.
Data center demand reshaping infrastructure economics
As more people use artificial intelligence, the demand for computing infrastructure is rising quickly across Europe.
European data center vacancy rates dropped to around 1.2% in late 2025, while prices for capacity increased by 34% year over year in major markets such as Dublin, Frankfurt, and Amsterdam.
The scarcity of available capacity is pushing developers to invest in new infrastructure models that bypass traditional bottlenecks.
However, building microgrid-powered facilities can be significantly more expensive. Such data centers may cost 25% to 40% more to construct because they include private power generation systems.
Even though they cost more, companies might still choose this model because it lets them open centers faster and rely less on crowded public power grids.
Potential blueprint for Europe’s AI infrastructure
The Irish project could be the start of a bigger change in how data centers are built across Europe.
The European Union’s revised Energy Efficiency Directive, which came into force in January 2026, encourages the use of renewable energy and decentralized energy systems such as microgrids.
By building power generation into the data center itself, developers might be able to add more computing capacity without waiting for big grid upgrades.
As artificial intelligence continues to drive unprecedented demand for computing power, the success of Ireland’s microgrid-connected facility could influence how future AI data centers are built across Europe.
