Electricity in.
Intelligence out.
AI lives in big buildings full of computers, plugged into the power grid. Estonia is turning one of them, at Hüüru near Tallinn, into a factory that makes intelligence.
What it is
A bakery turns flour into bread. This turns electricity into answers.
Power in, answers out, all day and all night. A cabinet of AI computers draws about ten times an ordinary one, and almost every watt comes back out as heat.[10][12]
A normal data centre is a library. An AI factory is a foundry.
Why it matters
Right now, almost none of this happens in Europe.
Nearly every AI tool Europeans use runs on machines owned somewhere else. Fine for everyday things. Not fine for a hospital, a bank or a ministry, which often may not send its records abroad at all.
The European Commission has said this out loud: too little computing capacity is holding the continent's own economy back. So it has started paying for buildings, not just for software.[14]
Whose courts you end up in when something goes wrong.
Why Estonia
Cold air, cheap clean power, and engineers who are already here.
The climate does the cooling
Cooling is the largest running cost after electricity. A cold country gets much of it free.[1]
Power is cheaper and cleaner
Electricity costs less than in the large western European markets, and most of it is now renewable.[1][18]
Building here costs less
Construction runs well below the Nordics, Frankfurt, London, Amsterdam, Paris and Dublin, at the same European standards.[1]
Inside the EU and NATO
One legal system, one currency, the NATO cyber defence centre and an EU border systems agency.[1]
The grid changed sides
In February 2025 the Baltics left the Russian-controlled power system for the Continental European grid, without blackouts.[19]
The skills already exist
Twenty years of a digital state and a software industry. The engineers who would run this are here.[20]
What Estonia gets out of it
Estonia already sells electricity. This sells what the electricity makes.
Run the same power through a building like this and it leaves as a service Europe pays much more for. The interesting part is not the technology. It is where the money ends up.
The same power, worth more
A kilowatt sold as computing time is worth far more than a kilowatt sold as electricity, and the difference is taxed here.
Jobs people actually want
Estonia's technology sector is 8% of the economy and pays about 1.8 times the average wage.[20]
Estonian keeps working
Big models handle Estonian by translating rather than understanding it. Researchers here train their own, and those models need somewhere to run.[13]
Nobody has published a figure for what this project adds to Estonian GDP, and we are not going to invent one. The numbers above describe the technology sector, not this one building.
What it is used for
Nobody buys computing power. They buy what it does.
Hospitals
Reading scans and spotting things early. Patient records are exactly the data that may not leave the country.[7]
Weather
Forecasts for farmers, shipping, storm warnings and energy planning. The EU lists this among the biggest wins.[15]
Factories
Spotting a faulty part on the line, and knowing a machine will fail before it does.[15]
Banks
Catching fraud while a payment is happening, under rules about where the data may sit.[7]
Government
Translation, documents and citizen services, on systems the state can audit itself.[7]
Smaller companies
Buying a room full of AI chips is out of reach. Renting a slice of someone else's is not.[7]
Services
Three ways in.
The building provides room, power, cooling and connection. You bring your own machines. The only difference is how much of the building is yours.[3]
- Space in a shared data hall
- Renewable-backed power and cooling
- Choose your own network providers
- Audited to the European standard
- A private room rather than shared space
- Being rebuilt for AI density
- Close to the Nordic network backbone
- Support and partner programmes
- Isolated and separately audited
- Everything stays inside EU jurisdiction
- Help with public sector compliance
- Site visit and full documentation
Colocation and dedicated rooms are the two lines the operator publishes.[3] Sovereign is not a named tier of theirs: it is what a dedicated room built to EU jurisdiction and public-sector audit requirements would look like. Pricing is not public either way, so confirm anything commercial with them directly.
The building
This building already exists.
The largest data centre in the Baltics, twenty minutes west of Tallinn, is now being rebuilt inside so AI computers can move in. Most of the money is being spent within the existing walls.[2][4]
Capacity opens
in late 2026.
The waitlist opens in the fourth quarter of 2026. Places go in the order they arrive.
