Estonia is to get its first large-scale artificial intelligence computing centre later this year after Nebius, the Nasdaq-listed cloud company, agreed to install 22 megawatts of capacity at a data centre near Tallinn.
The installation at Greenergy Data Centers in Hüüru, Harju County, will be Nebius’s first AI infrastructure deployment in the Baltic states. The companies say it will be the region’s largest AI factory when its first 22MW phase begins operating before the end of 2026.
Despite the industrial label, an AI factory does not manufacture physical products. It is a data centre built around clusters of powerful processors, high-speed networks and cooling systems that provide the computing capacity needed to train and run artificial intelligence models.
The project forms part of a €50 million expansion of the Hüüru data centre. MCF Group Estonia, the company behind Greenergy, appointed the Finnish company Caverion as the main contractor last month. The work will add 22MW of IT power and cooling, increasing the campus’s total capacity to 31.5MW. It is expected to be completed in the autumn.
Estonia sets its sights on becoming an AI hub
Nebius will become the first international AI cloud company to deploy its infrastructure at Greenergy. Its computing capacity will be offered to researchers, start-ups and larger companies developing and operating AI systems.
Tom Blackwell, Nebius’s chief communications officer, said Estonia was a “natural choice” because of its engineering talent, digital economy and start-up culture.
He said the company intended to work with the Estonian government, universities and industry to improve AI skills and make advanced computing infrastructure more widely available.
Kert Evert, the chief executive of Greenergy Data Centers, said securing Nebius as a customer showed that Estonia could compete for large international technology investments.
“Their decision to choose Greenergy is a strong recognition of our team’s work,” he said. “This is a start.”
Martin Salo, a co-founder of Tensor Estate, which recently became a shareholder in Greenergy, described the installation as the first phase of a broader development intended to establish Estonia as a centre for international AI infrastructure.
Finland, Sweden and Norway have so far attracted most of northern Europe’s biggest AI data centres, helped by relatively inexpensive electricity, a growing supply of renewable energy and a cold climate that reduces cooling costs. The Hüüru project brings Estonia into a market dominated until now by its Nordic neighbours.
Nebius accelerates its European expansion
Nebius already operates a 75MW facility at Mäntsälä in Finland and is building much larger AI factories in Lappeenranta, Finland, and Béthune, France. It also has deployments in Britain, Spain and Iceland.
The Amsterdam-based company emerged from the former Dutch parent of Yandex in 2024 after it sold its Russian businesses and severed its ties with the country. Its customers include Microsoft and Meta.
Nebius reported second-quarter revenue of $582.3 million on Wednesday, an increase of 454 per cent from a year earlier, although it recorded a net loss of $190.4 million from continuing operations.
The announcement did not disclose the value of Nebius’s contract, the number or type of processors to be installed or how many permanent jobs the project is expected to create.
