Cushman & Wakefield counts more than 12.1 GW of operational data center capacity across EMEA in H1 2026, up 36% in two years, with a further 18.3 GW in the development pipeline. The five FLAP-D hubs (Frankfurt, London, Amsterdam, Paris, Dublin) still hold about 43%, or 5.2 GW. CBRE reports that core-market take-up jumped 90% year on year to 572 MW in Q1 2026, with Frankfurt vacancy at 5% and rents of up to €225/kW/month. Grid limits are pushing growth outward. Frankfurt and West London face substation upgrades that may not arrive until the 2030s, Amsterdam caps new projects at 70 MW, and Ireland’s data centers already use 23% of the country’s metered electricity. The Nordics (about 2.1 GW live), Spain and Portugal are gaining. Policy money is arriving through the EU’s AI gigafactories call (up to €10bn public, at least €20bn private), France’s €109bn AI pledge and the UK’s AI Growth Zones.
Europe data center investment is entering a new phase: record demand in the traditional hubs, tightening grid rules, and a shift of capital towards the Nordics, Southern Europe and government-backed AI campuses. This guide maps where the money is going in 2026 and what is holding it back. It is part of the Data Center Economy hub; compare it with our guides to US data center investment and the Gulf data center race.
How big is Europe’s data center market?
Cushman & Wakefield puts EMEA operational capacity above 12.1 GW in H1 2026, with 3.8 GW under construction and 14.5 GW in planning.
Why is growth moving away from FLAP-D?
Grid capacity. Central Frankfurt and West London face substation upgrades that may not arrive until the 2030s, Amsterdam caps new projects at 70 MW, and Dublin’s new grid allocations are unlikely before 2027.
What are governments doing?
The EU launched a call in July 2026 for up to seven AI gigafactories, France is pursuing its €109bn AI pledge, and the UK has designated five AI Growth Zones. Some national grid operators are also tightening the rules for large loads.
How much data center capacity does Europe have in 2026?
Cushman & Wakefield reports that EMEA operational data center capacity passed 12.1 GW in H1 2026, up 36% from 8.9 GW in Q2 2024. A further 3.8 GW is under construction and 14.5 GW is in planning, a combined 18.3 GW development pipeline that grew more than 34% year on year.
That is fast growth, but Europe remains much smaller than the US. Synergy Research Group’s August 2026 ranking of hyperscale locations includes only one European market among the global top 20, against 15 in the US and four in Asia-Pacific. Dublin is the highest-placed European market. European operators say the gap reflects two things: more expensive and slower grid connections, and the absence of AI-lab anchor tenants on the scale of the US Stargate or Meta campuses.
Demand, though, is surging. CBRE’s Q1 2026 European figures show net absorption across London, Frankfurt, Paris and Amsterdam rising 90% year on year to 572 MW, and supply in those markets rising 18.9%. Vacancy across the core markets was stable at 7.3%, and rents rose in all four, with CBRE quoting $165–265 per kW per month for 250–500 kW requirements. Our vacancy and rent statistics by market compare these figures with Northern Virginia, Singapore and Tokyo.
What is happening in the FLAP-D markets?
The five FLAP-D hubs still dominate, holding about 43% of EMEA operational capacity (5.2 GW) and 1.17 GW under construction, according to Cushman & Wakefield. But each faces a power ceiling, so growth is spilling into satellite towns 25–40 km away and, increasingly, into other countries.
| Market | Operational capacity | Vacancy | Main constraint (2026) |
|---|---|---|---|
| London | 1.38 GW (largest in EMEA) | 8.6% | West London substation upgrade unlikely before early 2030s; growth shifting north |
| Frankfurt | 1.2 GW (+23% y/y) | 5% | Central grid constrained into the 2030s; projects moving up to ~40 km out |
| Amsterdam | 927 MW (+9% y/y) | n/a | Moratorium on new projects above 70 MW; growth shifting to Eemshaven and Middenmeer |
| Paris | Now 3rd-largest FLAP-D market | 6.7% | Long environmental reviews; development concentrated south of Paris |
| Dublin | Overtaken by Paris | n/a | Data centers use 23% of Irish metered power; new grid allocations unlikely before 2027 |

Capacity definitions differ between brokers.
London
London is EMEA’s largest market. Cushman & Wakefield puts it at 1.38 GW operational with a pipeline of about 1.77 GW. CBRE reports Q1 2026 take-up of 208 MW, maximum rents of around £170/kW/month, and vacancy edging up to 8.6% as new supply arrives. Large projects include Equinix’s Hertfordshire development of more than 250 MW, Colt’s Hayes expansion and Vantage’s planned Hertfordshire and Newham campuses, according to w.media. Microsoft has committed £22 billion to UK AI infrastructure over 2025–2028, and Google £5 billion.
Frankfurt
Frankfurt is the tightest core market, with 5% vacancy and Q1 2026 take-up of 218 MW, according to CBRE. Rents reach up to €225/kW/month for mid-size requirements. Grid upgrades in the central area are unlikely before the 2030s. Operator firstcolo told Real Asset Insight it was asked to wait ten years for power and is building a €250 million facility about 25 km outside the city instead. Germany’s Energy Efficiency Act adds PUE, waste-heat and renewable-power obligations, and developers are looking at Berlin, the Cologne area and northern Germany as alternatives.
Amsterdam, Paris and Dublin
Amsterdam grew just 9% year on year to 927 MW, held back by a moratorium on new projects above 70 MW. Colocation makes up 74% of its operational capacity, and new hyperscale growth is moving to Eemshaven and Middenmeer in the north of the Netherlands. Paris has overtaken Dublin as the third-largest FLAP-D market, helped by low-carbon nuclear power and France’s AI push, although long environmental reviews slow projects. Dublin, once the fastest-growing hub, is now capped by its grid. Ireland’s situation is covered in more detail below.
Why did Ireland restrict new data centers, and what changed?
Ireland effectively paused new Dublin connections because data centers were overwhelming the grid. The Central Statistics Office reports they used 23% of Ireland’s metered electricity in 2025, up from 5% in 2015. In December 2025, the regulator replaced the informal moratorium with strict conditions.
The Commission for Regulation of Utilities’ Large Energy Users Connection Policy, published on 12 December 2025, applies specifically to data centers. Sites of 10 MVA or more must bring dispatchable on-site or nearby generation or storage covering 100% of their grid import capacity, and cannot operate until it is delivered. All sites above 1 MVA must also contract new Irish renewable electricity equal to at least 80% of their annual demand. Connection offers depend on whether a site is in a constrained part of the grid.
Industry analysts at dcbyte describe the policy as reopening the grid, but on terms that favour large, well-capitalised operators able to build their own generation. New capacity in the constrained Greater Dublin Area is unlikely to come online before 2027. Ireland is a preview of where other European grids may head. Our guide to data center electricity consumption statistics puts Ireland’s 23% share in a global context.
Why are the Nordics attracting AI data centers?
The Nordics offer cheap, mostly renewable power, a cool climate and available land. Cushman & Wakefield counts about 2.1 GW of operational capacity in Scandinavia, up 20% year on year, and more than 3 GW in planning. Helsinki has passed 1 GW of total capacity.
Finland is the standout. According to Data Center Frontier’s October 2026 survey, Google plans €13 billion of investment over 2027–2028 across Hamina, Muhos, Vaala and Kajaani, backed by a 22-year nuclear PPA with Fortum. Fingrid says data centers with signed connection agreements total nearly 5 GW of eventual capacity. Proposed projects include Sesterce’s $10 billion, 600 MW campus at a former paper mill in Jämsä. In Norway, Nscale’s 230 MW Narvik campus, with Microsoft as anchor customer, plans to deploy more than 30,000 Nvidia Rubin GPUs during 2027 and has raised $790 million of additional bank financing. OpenAI exited the planned Stargate Norway lease at Narvik in April 2026, and Microsoft took over the capacity. In Sweden, Mistral AI and EcoDataCenter are investing €1.2 billion in Borlänge, with the first facility due in 2027.
The Nordic advantage is narrowing, however. Finland removed data centers from its preferential electricity-tax category from 1 July 2026, raising the rate from 0.05 to 2.24 euro cents per kWh. Denmark’s emergency grid agreement in October 2026 placed most large data centers in the lowest priority tier for constrained capacity. Fingrid warns that many areas are nearing connection limits, and CBRE has cautioned that speculative development could cause local oversupply.
Which Southern European markets are growing fastest?
Spain and Portugal are Europe’s emerging growth markets, offering solar power, land and new subsea cable landings. Cushman & Wakefield names Madrid, Barcelona and Zaragoza among the markets attracting growing interest, and CBRE expects Lisbon to grow from about 50 MW today to as much as 500 MW by 2030.
Aragon in north-east Spain has become the region’s hyperscale hotspot. Reuters reported in August 2025 that Blackstone plans €7.5 billion for an eight-building campus there, with construction starting in Q2 2026, plus a possible €4.3 billion second phase. Microsoft and Amazon have also chosen Aragon, and the regional government had about 20 data center projects under evaluation. Madrid is Spain’s main colocation and interconnection market, and Milan is the principal Italian hub.
Grid access and water are the main local debates in the south. Spanish projects are increasingly pairing data centers with on-site solar and air-based or closed-loop cooling. Our explainer on air, liquid and immersion cooling covers the water-versus-energy trade-off.
What are the EU AI gigafactories?
AI gigafactories are very large EU-backed compute clusters for training frontier AI models. The EuroHPC Joint Undertaking launched the formal call on 30 July 2026 for up to seven facilities, aiming to unlock more than €30 billion of combined public and private investment.
The call has two lots: up to four facilities in Lot 1 and up to three larger ones in Lot 2. EU and national funding of up to €10 billion is available, matched by at least €20 billion of private investment. Lot 1 projects can receive up to €100 million in a first phase and €400 million more in a second; Lot 2 projects up to €200 million and €800 million. Each gigafactory must deploy a multiple of the processors in Europe’s most powerful existing AI factory, rising to at least three or four times that level in phase two. Proposals close on 12 November 2026, awards are expected in early 2027, and selected sites must begin operations within 18 months of contract signature.
The gigafactories sit within the EU’s broader InvestAI initiative, and the European Investment Bank signed a memorandum with the Commission in December 2025 to help finance them. Consortia can span several member states. That opens the door for bids combining Nordic or Iberian power with partners in other EU countries, though final site choices will depend on grid availability as much as on subsidies.
How are France and the UK competing for AI data center investment?
France is selling low-carbon nuclear power and a €109 billion pipeline of AI investment pledges announced in February 2025. The UK is selling AI Growth Zones with faster planning and power access. Both have landed large projects, and both have seen high-profile withdrawals.
France
The flagship French project is Campus IA, a joint venture of MGX, Bpifrance, Mistral AI and Nvidia. It plans up to eleven data centers totalling about 1.4 GW on roughly 90 hectares at Fouju in Seine-et-Marne, south-east of Paris. The prefecture authorised the project on 29 July 2026 after a one-month public consultation, according to Mac4Ever. Opposition remains active: a petition against the campus gathered 50,000 signatures, and critics cite farmland loss, heat output and backup-generator pollution. The wider €109 billion package included pledges from MGX for a 1 GW campus, Brookfield for a northern France data center and Microsoft, though how much of the total has been committed is not publicly tracked.
United Kingdom
The UK government has designated five AI Growth Zones: Oxfordshire (April 2025), the North East (September 2025), North Wales and South Wales (November 2025) and Scotland (January 2026). The North East zone, at Blyth and Cobalt Park, targets up to £30 billion of private investment and 5,000 jobs. It includes a £10 billion Blackstone commitment at Blyth and an energy capacity target of 1.1 GW within six years. The UK’s challenge is the cost of power: OpenAI’s decision to pause Stargate UK showed that industrial electricity prices and grid connection times are still significant hurdles.
What are the biggest risks to European data center investment?
The main risks are grid capacity, high electricity prices, stricter efficiency and heat-reuse regulation, and local opposition. Weak AI demand is not the problem: core-market take-up nearly doubled in Q1 2026. Execution risk is high, and many announced projects will slip or be cancelled.
Regulation is tightening on several fronts. Ireland requires matching generation and renewable contracts, and Amsterdam caps project size. Denmark and Finland are reprioritising grid access and tax treatment, and Germany’s efficiency rules impose PUE and waste-heat obligations. The EU’s Energy Efficiency Directive reporting requirements, covered in our article on data center sustainability, add disclosure costs.
On the positive side, Europe’s sovereign-cloud push, the gigafactories programme and private capital are all pushing in the same direction. Large infrastructure investors such as Blackstone, Brookfield and the Gulf funds have committed billions. Our profile of private equity data center platforms shows how these investors build and recycle capital, and our site selection guide explains why power availability now outranks latency for AI campuses.
Frequently Asked Questions
What does FLAP-D stand for?
FLAP-D refers to Europe’s five traditional data center hubs: Frankfurt, London, Amsterdam, Paris and Dublin. Cushman & Wakefield estimates they hold about 43% of EMEA operational capacity, or 5.2 GW, in H1 2026. London is the largest at 1.38 GW. Paris has recently overtaken Dublin as the third-largest by total capacity.
Which European country is growing fastest for data centers?
Growth is fastest outside the traditional hubs. Scandinavia’s operational capacity rose about 20% in a year to 2.1 GW, and Helsinki has passed 1 GW of total capacity. Finland has nearly 5 GW of signed grid connection agreements, according to Fingrid. In Southern Europe, Spain’s Aragon region and Portugal’s Lisbon market are expanding quickly, with CBRE forecasting Lisbon could reach 500 MW by 2030.
Is there still a data center moratorium in Dublin?
Not formally. In December 2025, Ireland’s energy regulator replaced the informal pause with a connection policy for data centers. Large sites must provide on-site or nearby dispatchable generation equal to their grid connection and match at least 80% of their demand with new Irish renewables. New capacity in the constrained Dublin area is unlikely before 2027.
How much money is the EU putting into AI gigafactories?
The EuroHPC call launched in July 2026 offers up to €10 billion of combined EU and national funding for up to seven AI gigafactories. Bidders must bring at least €20 billion of private investment, for more than €30 billion in total. Proposals close on 12 November 2026, with awards expected in early 2027.
