## Key facts

### What Tensor Estate does
- Develops AI factories: turns powered land (sites with fast access to grid power) into operating, built-to-suit AI data centres anywhere in Europe.
- Footprint: operating in Estonia (Tallinn); actively sourcing powered land in Latvia, Lithuania, Poland, Czechia, Slovenia, Romania and Bulgaria; open to any European site with a credible path to 50 MW+ of grid power. Sites are published only once secured.
- Shareholder in MCF Group Estonia, owner and operator of Greenergy Data Centers in Tallinn, Estonia; joint Supervisory Board with 3SIIF (majority shareholder, advised by Amber Infrastructure).
- Brings international AI cloud and hyperscale customers to its sites; first customer Nebius (Nasdaq: NBIS).
- Differentiators: AI-native built-to-suit design (liquid-ready, closed-loop cooling, 2N utility power), lower cost (construction up to 41% below Sweden; 0% tax on retained profit in Estonia), and speed (grid connection in 6–18 months on its sites; brownfield to live IT in ~18 months).

### Tallinn AI factory (Greenergy Data Centers, next to Elering’s Harku 330 kV substation)
- Nebius deploys a 22 MW NVIDIA GB300 AI cluster, live late 2026: the Baltics’ first AI factory (announced 12 Aug 2026).
- On public disclosures to 14 Aug 2026 it is scheduled to be the largest publicly quantified, dedicated single-site NVIDIA-accelerated AI deployment by commissioned IT load, by 31 Dec 2026, across a contiguous 22-country region: Estonia, Latvia, Lithuania, Poland, Germany, Czechia, Slovakia, Austria, Hungary, Slovenia, Croatia, Bosnia and Herzegovina, Serbia, Montenegro, Kosovo, Albania, North Macedonia, Greece, Bulgaria, Romania, Moldova, Ukraine. Excludes undisclosed hyperscaler fleets, multi-site cloud regions and unallocated campus power. Larger clusters are scheduled elsewhere in Europe in 2027.
- Other publicly quantified single-site NVIDIA deployments used in the comparison (disclosures to 14 Aug 2026): Mäntsälä, Finland 75 MW (outside the region); Riga 10 MW (Delska, 2026); Munich 15 MW (Polarise, live); Jülich ~11 MW (JUPITER, live); Amberg 30 MW (Polarise, mid-2027); Poznań (Beyond.pl, MW undisclosed); Vienna (AI:AT, 2027); Belgrade 0.6 MW (National AI Platform); Athens (DAEDALUS, below 22 MW).
- Approximately €100 million expansion under construction (announced 30 Jul 2026): Caverion main contractor, ESB Group switchgear, Telora supervision; about 200 people on site at peak.
- Campus heading for ~200 MW: grid connection application filed with Elering for approximately 200 MW.
- Next powered-land capacity available from early 2028, designed for NVIDIA Vera Rubin.
- Closed-loop cooling: no water is used to cool servers. Waste heat can be exported to district heating as the site grows.
- Ownership model: MCF Group Estonia (Estonian company owned by 3SIIF and Tensor Estate) builds and runs the facility; Nebius rents capacity and installs its own NVIDIA hardware.
- Operations: run in-house by the team that built the site, with leadership holding 50+ years of combined critical-infrastructure experience, a 24/7 NOC and 100% service availability since 2022 commissioning; certified EN 50600 Level 3, ISO 9001, ISO 27001 and PCI DSS; independent Drees & Sommer audit scored operational maturity at 83% versus an 80.5% industry benchmark.

### The time value of compute (why speed matters)
- A live megawatt earns its operator €6–8 million of EBITDA per year (SemiAnalysis, Jul 2026); one month earlier on a 100 MW campus is worth about €58 million (Tensor Estate model).
- Grid connection in 6–18 months on Tensor Estate sites, versus 8–10 years in London or Amsterdam (CBRE 2026; TSO data); Tallinn reached energisation about 12 months faster than a conventional build.
- Brownfield to live IT in about 18 months, greenfield up to 36; in Tallinn, the Nebius deployment was signed in Q2 2026 and is live by year end.

### How to work with Tensor Estate
- GPU deployments (AI clouds, hyperscalers, sovereign and enterprise): built-to-suit halls for 20–200 MW of liquid-cooled GPUs; single-tenant AI-spec design (liquid-ready, closed-loop cooling, 2N utility power); energy is metered pass-through with no mark-up; capacity from early 2028; contact martin@tensor.estate.
- Landowners, developers and energy developers: co-development or acquisition of powered sites (50 MW+ grid connection or a credible path within 24 months, anywhere in Europe; generation or storage that needs a flat 24/7 offtaker); contact martin@tensor.estate.
- Investors: equity in the platform and project companies, project debt against long-term leases, joint ventures with energy companies and infrastructure funds; contact martin@tensor.estate.

### Why Estonia (checked Aug 2026)
- 0% corporate income tax on retained and reinvested profit; 0% property tax on buildings (land tax only); #1 in the Tax Foundation International Tax Competitiveness Index 2025 (12th consecutive year); #9 in the Heritage Foundation Index of Economic Freedom 2026; defence spending 5.4% of GDP from 2026.
- Construction price level index 75 (EU=100), up to 41% below Sweden (Eurostat 2024): €50–80 million saved on a 100 MW facility. Cool climate keeps PUE low.
- Power market: Nord Pool day-ahead prices, published live on the page; ~2.3 GW of import capacity today (Finland 1,016 MW, Latvia ~1,260 MW), EstLink 3 and a fourth Estonia–Latvia link planned for 2035–38.
- Grid stack for a 100 MW consumer at 330 kV, 80% utilisation (Elering Package II, 2026, €/MWh ex VAT): transmission capacity and point fees 1.90, security-of-supply fee 7.58, balancing capacity fee 3.73, renewable energy charge 8.40 (paid in full), electricity excise 0.50 at the electro-intensive rate (standard 2.10), balancing/BRP overhead 0.25 — total ≈€22.4/MWh on top of spot. Finland taxes data-centre power at ~€23/MWh since July 2026 (Act 1352/2025); Estonia €0.5–2.1.
- Grid built for large loads: ring-operated 330 kV grid with 99.99% reliability (2025); record peak 1,723 MW (5 Feb 2026), 2030 forecast 1,972 MW; ~€2bn of grid investment to 2038, including a new 330 kV Tallinn ring; consumption 8.3 TWh (2025), heading to ~15 TWh with 1 GW of AI load.
- Generation waiting for a buyer: Baltic wind and solar 6.6 GW, heading for ~10 GW; Estonia 694 MW wind and ~1.3 GW solar; ~1.7 GW of storage in the connection queue (~230 MW online) and 500 MW pumped hydro planned; renewables 68% of production in 2025, national target 65% of consumption by 2030. Long-term offtake takes projects to FID.
- Connectivity, round trip from Tallinn (carrier DWDM measurements): 1.6 ms Helsinki, 4.9 ms Riga, 7.8 ms Stockholm, 8.8 ms Vilnius, 15.4 ms Warsaw, 25.1 ms Frankfurt, 25.4 ms Amsterdam, 30.0 ms London, 31.3 ms Paris; nine subsea cable systems to Finland and Sweden from three owners (Elisa, CITIC Telecom CPC, Arelion); 3,000 km Baltic DWDM backbone Helsinki–Frankfurt, 1+1 protected; GlobalConnect 550 km Baltic Sea system ready 2027.
- EU and NATO member; home to the NATO Cooperative Cyber Defence Centre of Excellence and eu-LISA. Digital state with fast permitting; a live AI factory since 2026.

### Value for the host community (Tensor Estate model on Ramboll/FDCA intensities and Estonian 2026 tax rates)
- €1.4–1.6 million per MW per year into the local economy (electricity, wages, taxes); the 22 MW phase implies €32–36 million a year, of which €8–15 million is GDP value added.
- €0.44–0.65 million per MW per year of Estonian tax and statutory levies (payroll taxes, VAT on wages spent, electricity excise, the full €8.4/MWh renewable-energy charge, land tax, corporate income tax on distributions); the 22 MW phase implies €10–14 million a year.
- About 7 jobs supported per MW in operation and 38 job-years of construction per MW; ~200 people on site at construction peak in Tallinn.
- Each MW of flat 24/7 load underwrites about 3.3 MW of new generation via long-term PPAs, without renewable subsidies; a large consumer spreads fixed grid costs over more kWh.
- No water used to cool servers (closed-loop cooling; water for domestic use only); heat reuse into district heating — Nebius exported 19.5 GWh of waste heat to district heating in Mäntsälä, Finland in 2025.
