European AI cloud company Nebius has signed an agreement with Greenergy Data Centers to install 22MW of capacity at a data center in Hüüru, to the west of Estonia’s capital city, Tallinn.
Key facts
- Nebius founder and CEO, Arkady Volozh, briefly referenced the deployment in his letter to shareholders, published alongside the neocloud’s Q2 2026 results
- The UK expansion refers to the 22MW capacity agreement Nebius signed with Kao Data in June 2026, set to be deployed at the latter’s Harlow campus, and a deal announced this week to lease capacity
- Nebius has a data center presence across the US, the Middle East, and Europe
- In a post on Nebius’ LinkedIn page today (August 13), the company announced it was building a second data center in Mäntsälä, in the south of Finland
Summary
The first phase of capacity is expected to be operational later this year, and will be the largest deployment in the Baltics when all 22MW is made available. Following Russia’s invasion of Ukraine, Nebius rose from the ashes of Yandex and is now positioning itself as a major player in the AI cloud space. "Nebius' Tallinn AI factory, which is being developed in partnership with Greenergy Data Centers, will provide state-of-the-art infrastructure to support Estonia's growing innovation ecosystem and help accelerate the development and adoption of artificial intelligence," said Nebius’ head of communications, Tom Blackwell, adding that Estonia was a natural choice for the company due to its engineering talent, digital economy, and start-up culture.
