Headline statistic. Italy has 609 MW of data center IT capacity installed and 68,500 MW of high-voltage connection requests filed with Terna. Axis Intelligence Research expresses that gap as a Paper-to-Live Ratio (PLR) of 112.5: for every megawatt running, 112.5 more wait in the grid queue — the widest reading measured anywhere in Europe.
Quick Answer
Germany has the largest measured data center capacity in continental Europe: 2,980 MW of connected IT load in 2025, per Bitkom and the Borderstep Institut. The UK follows at roughly 2.0 GW operational at end-2025, then Italy (609 MW IT) and Spain (439 MW commercial). Axis Intelligence Research finds that grid queues in Italy, France, Norway and the UK now exceed live capacity by 5.5 to 112.5 times.
Key Findings
- Axis Intelligence Research calculates Italy’s Paper-to-Live Ratio at 112.5: 68,500 MW of Terna high-voltage requests (November 30, 2025) against 609 MW of installed IT capacity.
- Axis Intelligence Research calculates France’s Paper-to-Live Ratio at 15.8: RTE had reserved about 18,000 MW for data centers by May 2026, against an average draw of 1,141.6 MW implied by RTE’s 10 TWh consumption estimate.
- Axis Intelligence Research finds Norwegian data centers use 18.3% of the grid capacity allocated to them (794 of 4,350 MW, April 2026) — within two points of the 20% RTE observes at recently connected French sites.
- Axis Intelligence Research estimates German data centers run at 54.4% average IT utilisation, dividing the IT share of Bitkom’s 21.3 TWh 2025 electricity estimate by 2,980 MW of connected IT capacity.
- Hessen alone hosts a little over 1,100 MW of data center capacity (Bitkom, 2025) — more than Italy (609 MW) and Spain (439 MW) combined, which Axis Intelligence Research totals at 1,048 MW.
Why “Capacity by Country” Is Harder to Measure Than It Looks
No European statistical office publishes a single table of data center megawatts by country. The closest thing, the European Commission’s database under the Energy Efficiency Directive, aggregated 6,400 MW of installed IT power from 776 reporting data centers across 18 countries for 2023–2024, as reported by DatacenterDynamics. That figure covers only sites of 500 kW and above that actually filed — and Germany’s own market count lists 2,000 data centers above 100 kW.
So this page does what the official record does not: it assembles each country’s best primary measurement, labels the basis of every number (IT load, electrical capacity, metered energy, grid reservation), and never adds numbers built on different bases. The European Commission’s energy performance page for data centres states the policy aim this data has to be judged against: the EU wants to triple its data center capacity by 2035.
For the wider context — electricity, efficiency and market size across the region — see the Europe data center statistics hub. This page is about one thing: megawatts, where they are, and how many of them exist only on paper.
Which European Country Has the Most Data Center Capacity?
The table below lists every country where a primary source publishes a national capacity figure in megawatts. The basis column matters more than the number column.
| Country | Capacity | Basis | As of | Source |
|---|---|---|---|---|
| Germany | 2,980 MW | IT connected load, all sites >100 kW | 2025 | Bitkom / Borderstep |
| United Kingdom | ~2,000 MW | Operational electrical capacity, 348 live sites | End-2025 | CITP |
| United Kingdom | ~1,600 MW | Total capacity (government-cited) | 2024 | House of Commons Library |
| Italy | 609 MW | Installed IT load | 2025 | Osservatorio Data Center, Politecnico di Milano |
| Spain | 439 MW | Installed IT load, commercial (colocation + hyperscale) | End-2025 | SpainDC |
| Norway | 794 MW | Grid capacity in use | April 2026 | Statistics Norway (citing Statnett) |
| France | 800 MW | Only the 8 sites connected directly to RTE’s HV/EHV grid | June 2026 | RTE |
France is the obvious hole. RTE counts about 300 data centers in the country, but only eight are wired straight into its high-voltage network, and those eight total 800 MW. Everything else sits on distribution grids and does not appear in a national MW figure. CBRE Research supplies a useful cross-check: its 2026 outlook describes the 750 MW of capacity it expects Europe to add this year as equal to all French colocation capacity as of 2025.
Ireland and the Netherlands publish no official MW total at all. They publish something arguably better — metered electricity — which Axis Intelligence Research converts to average continuous load below.
James Porter: Read the basis column before you quote anything. “IT load” is what the servers can draw. “Electrical capacity” includes cooling and losses. “Grid capacity in use” is what the operator contracted and is actually pulling. They are three different numbers for the same building. Mix them in one chart and you have built a comparison that measures your own confusion.
How Big Is Germany’s Data Center Market by State?
Bitkom’s regional split shows how concentrated German capacity is. Hessen — effectively Frankfurt and its hinterland — holds a little over 1,100 MW, which Axis Intelligence Research calculates at 36.9% of the national 2,980 MW.
| German state | IT capacity (MW) | Source |
|---|---|---|
| Hessen | a little over 1,100 | Bitkom / Borderstep, 2025 |
| Bayern | 420 | Bitkom / Borderstep, 2025 |
| Nordrhein-Westfalen | 378 | Bitkom / Borderstep, 2025 |
| Baden-Württemberg | 233 | Bitkom / Borderstep, 2025 |
| Berlin | 146 | Bitkom / Borderstep, 2025 |
| Mecklenburg-Vorpommern | 20 | Bitkom / Borderstep, 2025 |
| Bremen | 19 | Bitkom / Borderstep, 2025 |
| Saarland | 17 | Bitkom / Borderstep, 2025 |
By workload, cloud infrastructure accounts for 1,450 MW, classic enterprise data centers 1,290 MW and edge sites 240 MW, per the same study. AI-dedicated capacity stands at 530 MW and is projected to reach 2,020 MW by 2030. Bitkom counts 100 sites above 5 MW within the 2,000-site total, and puts national capacity at 5,000 MW by 2030 — a 1.68x multiple on today’s base.
The international yardstick is sobering. Bitkom puts US data center capacity at 48,000 MW in 2024 and China’s at 38,000 MW; Axis Intelligence Research calculates the US figure at 16.1 times Germany’s 2025 total.
How Much Capacity Do Italy and Spain Have?
Milan holds 414 MW of IT load — 68% of Italy’s installed base, according to the Osservatorio Data Center of the Politecnico di Milano. That share implies a national base of about 609 MW, matching the 609 MW figure the Osservatorio reported for 2025. The same research counts 7,400 MW of active IT capacity across Europe’s 13 main data center hubs, and places Madrid at 390 MW.
Spain’s association SpainDC reports 439 MW of commercial IT capacity at end-2025, up 24% in a year, with a current-trend scenario of 2,537 MW by 2030 and Madrid alone projected at 612 MW. Axis Intelligence Research calculates that 2030 scenario at 5.78 times the 2025 base, the steepest growth multiple of any country on this page.
James Porter: Southern Europe’s numbers are small and growing fast, which is exactly when projections deserve the hardest look. A 5.78x multiple in five years assumes substations, transformers and transmission lines arrive on schedule. They rarely do. Plan around the connected megawatts, not the brochure megawatts.
How Much Capacity Do the FLAP-D Markets Have in 2026?
Frankfurt, London, Amsterdam, Paris and Dublin reached around 3,800 MW of combined live colocation capacity by H1 2026, up from 1,800 MW in 2019, per JLL’s EMEA data centre mid-year 2026 report. Axis Intelligence Research calculates that as a 2.11x expansion in seven years. A further 1,400 MW is under construction and 2,000 MW planned.
Which FLAP-D City Added the Most Capacity in H1 2026?
| Metro | H1 2026 deliveries (MW) | Colocation vacancy, Q2 2026 | Source |
|---|---|---|---|
| Paris | 72.5 | 8.0% | JLL, 2026 |
| London | 49 | 7.4% | JLL, 2026 |
| Frankfurt | 45 | 3.1% | JLL, 2026 |
| Amsterdam | 16.3 | 6.5% | JLL, 2026 |
| Dublin | 11.4 | 7.2% | JLL, 2026 |
| FLAP-D total | 194 | 6.4% | JLL, 2026 |
JLL forecasts about 453 MW of full-year FLAP-D deliveries. Frankfurt, the tightest market at 3.1% vacancy, carries 311 MW in development and 687 MW planned — 998 MW combined, by Axis Intelligence Research’s addition — but JLL notes connection lead times of 24 months or more. Prime powered land across FLAP-D now costs €2.26 million per MW, up from €1.24 million in 2021.
Europe-wide, CBRE Research forecasts vacancy across primary and secondary markets falling to 6.5% by the end of 2026.
James Porter: Paris led H1 because RTE can deliver high-voltage connections. Frankfurt trailed its own pipeline because the grid cannot. Same demand, different substations. Capacity follows copper, not ambition.
What Is the Paper-to-Live Ratio (PLR)?
The Paper-to-Live Ratio (PLR) is an Axis Intelligence Research metric: the megawatts of grid capacity requested, reserved or allocated for data centers in a country, divided by the megawatts of data center load actually running there. A PLR of 1 means the queue matches what exists. A PLR of 100 means for every megawatt humming in a hall, a hundred more sit in a grid file.
It exists because announcement totals are the most-quoted and least-reliable numbers in this sector. Italy’s Osservatorio said it plainly in January 2026: requests to Terna in 2025 ran 100 times the installed base. PLR turns that observation into a comparable, recomputable number for every country where the inputs are public.
Formula: PLR = paper capacity (MW) ÷ live capacity (MW). Where a country publishes installed MW, that is the denominator. Where it publishes only electricity, live capacity is the average continuous load: TWh × 1,000,000 ÷ 8,760 hours.
Paper-to-Live Ratio by Country, 2026
| Country | Paper capacity | Live capacity | PLR | Basis | Source |
|---|---|---|---|---|---|
| Italy | 68,500 MW HV requests (Nov 30, 2025) | 609 MW installed IT | 112.5 | Requests ÷ installed IT | Osservatorio Data Center, PoliMi |
| Italy — Milan area | 31,100 MW | 414 MW | 75.1 | Requests ÷ installed IT | Osservatorio Data Center, PoliMi |
| France | ~18,000 MW reserved (May 2026) | 1,141.6 MW average load | 15.8 | Reserved ÷ average draw | RTE; Axis calculation |
| Norway (incl. queue) | 4,350 MW allocated + 6,833 MW queued | 794 MW in use | 14.1 | Grid ÷ grid in use | Statistics Norway / Statnett |
| United Kingdom | 870 MW under construction + 10,880 MW pipeline | ~2,000 MW operational | 5.9 | Pipeline ÷ operational | CITP |
| Norway | 4,350 MW allocated | 794 MW in use | 5.5 | Grid ÷ grid in use | Statistics Norway / Statnett |
| Germany | 3,168 MW named new projects | 2,980 MW IT | 1.1 | Named projects ÷ IT | Bitkom / Borderstep |
Germany’s reading is a floor, not a verdict: Bitkom lists Frankfurt projects as “more than” 1,800 MW, plus 888 MW in Brandenburg and 480 MW in Nierstein, and no national grid-queue figure is published. Ireland and the Netherlands have no public national reservation total, so they carry no PLR reading.
James Porter: A high PLR is not a boom. It is a queue. Italy’s 112.5 says developers are filing for power the way people reserve restaurant tables — everywhere at once, cancel later. The number that tells you what gets built is the denominator. Watch that one.
Why Do Data Centers Use Only a Fifth of Their Grid Capacity?
Two unrelated grid operators, two different methods, one answer. RTE reports that data centers connected to its network in the last two to three years draw on average only 20% of the power they requested. In Norway, Axis Intelligence Research calculates that existing data centers use 794 MW of the 4,350 MW allocated to them — 18.3%.
The reason is mechanical, not speculative. RTE explains that operators install expensive processors only as customer demand arrives, and expect ten to fifteen years to reach about 80% of requested power; the remaining 20% is safety margin for heat waves and failover. The building gets energised years before the racks fill.
That ramp matters for how the grid plans. In Île-de-France, RTE says requested data center power (6,500 MW) is now close to the region’s entire average power demand (7,000 MW) — 92.9%, by Axis Intelligence Research’s calculation.
How Much Power Do Data Centers Actually Draw in Each Country?
For countries without an official MW census, metered or estimated electricity gives the most defensible view of live capacity. Axis Intelligence Research converts each figure to average continuous load. For national electricity shares and demand trends, see our Europe data center power demand analysis; this table exists only to size live capacity.
| Country | Data center electricity | Year | Average continuous load (Axis calc.) | Source |
|---|---|---|---|---|
| Germany | 21.3 TWh | 2025 | 2,431.5 MW | Bitkom / Borderstep |
| France | ~10 TWh | 2026 estimate | 1,141.6 MW | RTE |
| Ireland | 7,663 GWh | 2025 | 874.8 MW | CSO Ireland |
| Netherlands | 5,100 GWh | 2024 | 582.2 MW | CBS |
| Norway | 3.3 TWh | 2025 | 376.7 MW | NVE |
Ireland’s 874.8 MW is the same registry value published on our global data center statistics page. Data centers took 23% of Ireland’s metered electricity in 2025. In the Netherlands, CBS counts about 200 data centers, with roughly 45 large sites taking about 90% of supply.
What Is Germany’s Real Data Center Utilisation?
Bitkom states that about two-thirds of German data center electricity goes to IT equipment. Applied to 21.3 TWh, that is 14.2 TWh of IT energy — an average IT draw of 1,621.0 MW. Axis Intelligence Research estimates German data centers therefore run at 54.4% average utilisation of their 2,980 MW connected IT capacity.
This is an estimate, built from one source’s energy total and one source’s capacity total, both from the same Bitkom/Borderstep study so the scopes match. It is the only country on this page where that pairing is possible.
James Porter: 54% is not waste. Redundant power paths, N+1 cooling and headroom for peak are the job. A site running at 95% average is one failed chiller from an incident report. The useful question is not “why so low” but “how much of the gap is design margin and how much is empty halls” — and nobody publishes that split.
How Fast Will European Data Center Capacity Grow by 2030?
National outlooks use different units, so they are listed side by side rather than summed.
| Country | Current | 2030 outlook | Multiple (Axis calc.) | Source |
|---|---|---|---|---|
| Germany | 2,980 MW (2025) | 5,000 MW | 1.68x | Bitkom / Borderstep |
| Spain | 439 MW (2025) | 2,537 MW (current-trend scenario) | 5.78x | SpainDC |
| United Kingdom | 1,600 MW (2024) | 3,300–6,300 MW | up to 3.94x | House of Commons Library |
| France | ~10 TWh | 15–20 TWh | — | RTE |
| Ireland | 9.4 TWh (2025, EirGrid) | 14.6 TWh (2034) | — | CRU, citing EirGrid |
| Denmark | — | 6.0 TWh (2030); 26.8 TWh (2040) | — | Danish Energy Agency, AF25 |
| EU | 70 TWh (2024) | 115 TWh | — | European Commission, citing IEA |
The EirGrid forecast cited by CRU puts Irish data centers at 31% of national electricity demand by 2034. Note the gap between EirGrid’s 9.4 TWh estimate for 2025 and CSO’s metered 7,663 GWh — forecasts and meters rarely agree, and the meter is the one to trust for what already happened.
JLL expects over half of Europe’s AI capacity growth in the Nordics and Tier 2 markets, because AI training loads of 100 MW and above follow available power rather than latency.
James Porter: Every row above assumes the grid shows up. Ireland already reset its connection policy; France built a fast-track for five sites; Norway runs a queue. The 2030 map will be drawn by transmission operators, not by the press releases in the pipeline column.
Methodology
Collection. Axis Intelligence Research fetched every figure on this page from its publishing organisation between September 9 and 10, 2026: national statistical offices (CSO Ireland, CBS, Statistics Norway), grid and energy authorities (RTE, NVE, CRU, Danish Energy Agency), the European Commission, the House of Commons Library, and market research published by Bitkom/Borderstep, the Politecnico di Milano’s Osservatorio Data Center, SpainDC, JLL and CBRE. Three figures reach us through press coverage of a primary release — the EED aggregate (DatacenterDynamics), Italy’s 609 MW total (ElettricoMagazine) and the UK’s end-2025 site count (CITP’s dataset) — and are marked is_primary = no in the CSV.
Average continuous load. MW = annual energy (MWh) ÷ 8,760 hours. It measures average draw, not peak or installed capacity, and is used only where a country publishes energy but not capacity.
Paper-to-Live Ratio (PLR). PLR = paper capacity ÷ live capacity, with the basis of both inputs stated per row. PLR readings are compared within a basis first; the cross-country table ranks orders of magnitude, not decimal points.
German utilisation. (21.3 TWh × 2/3) × 1,000,000 ÷ 8,760 ÷ 2,980 MW = 54.4%. The two-thirds IT share is Bitkom’s own statement.
What we did not do. We did not sum national figures into a “Europe total,” because the inputs mix IT load, electrical capacity and energy. The closest defensible regional totals are JLL’s 3,800 MW for FLAP-D and the Osservatorio’s 7,400 MW across 13 hubs, each quoted on its own terms.

Grid Queues, Megawatts and Siting: Questions Answered
Can a data center get a grid connection in Dublin in 2026?
Not on the old terms. Ireland’s regulator CRU now requires large new data centers to bring dispatchable onsite or nearby generation or storage matching their maximum import capacity, and to show a credible plan for associated renewables. JLL reports the framework, live since March 31, 2026, is steering developers away from the Greater Dublin Area toward regional sites.
Why is Frankfurt’s vacancy so low when it has nearly 1 GW in the pipeline?
Because pipeline is not power. JLL puts Frankfurt vacancy at 3.1% in Q2 2026 with 311 MW in development and 687 MW planned, but connection lead times of 24 months or more pace every delivery. Frankfurt added 45 MW in H1 2026 against Paris’s 72.5 MW.
What does “MW IT” mean compared with total facility power?
MW IT is the power available to servers, storage and network gear. Total facility power adds cooling, UPS losses and building systems. In Germany, Bitkom attributes about two-thirds of data center electricity to IT equipment and one-third to building infrastructure, which is why facility figures always run higher than IT figures for the same site.
How much grid capacity has France reserved for data centers?
About 18,000 MW for roughly 80 projects as of May 2026, up from about 5,000 MW for around 40 projects at end-2024, per RTE. Île-de-France holds about 7,000 MW of those reservations and Hauts-de-France about 6,000 MW. RTE projects French data center consumption of 15–20 TWh in 2030.
Is Italy’s 68.5 GW of connection requests real demand?
The Politecnico di Milano’s Osservatorio says no: it calls the requests far removed from real values even in the most optimistic forecasts. Axis Intelligence Research’s Paper-to-Live Ratio for Italy is 112.5, and 75.1 for the Milan area alone, where 31,100 MW of requests sit against 414 MW installed.
Which country is best placed for a 100 MW+ AI training cluster?
Where power can be connected fastest, not where fiber is densest. JLL notes AI training requirements of 100 MW and above follow available power, and expects over half of Europe’s AI growth in the Nordics and Tier 2 markets. Norway’s queue — 6,833 MW awaiting Statnett processing in April 2026 — shows how crowded that route has become.
How many data centers does Germany have?
Bitkom and the Borderstep Institut count 2,000 data centers with more than 100 kW of connected load, including 100 larger sites above 5 MW. Together they reached 2,980 MW in 2025, up 9%, and the hundred largest contribute about half of that capacity.
Why don’t the European Commission’s EED figures match national totals?
The EED database collects only data centers with installed IT power of 500 kW or more, and only those that have reported. Its 2023–2024 aggregate — 6,400 MW across 776 sites in 18 countries, with a weighted average PUE of 1.36 — is a floor, not a census. National studies with lower thresholds, such as Germany’s 100 kW cut-off, capture far more sites.
