Germany's National Data Centre Strategy, adopted by the federal cabinet on 18 March 2026, sets a goal of at least doubling data centre capacity (IT connected load, vs 2025) by 2030. The same document notes that under § 11(5) of the Energy Efficiency Act operators must cover their electricity use 50% from renewables from 1 January 2024 and 100% (on a balance-sheet basis) from 1 January 2027, and states that grid connection capacity is scarce, especially in existing hotspots, with long connection times.

The National Data Centre Strategy, published after the federal cabinet decision of 18 March 2026, sets the target of at least doubling data centre capacity in Germany by 2030, measured as IT connected load (MW) against 2025. Bundesregierung / BMDS – Nationale Rechenzentrumsstrategie
Under § 11(5) of the Energy Efficiency Act (EnEfG), as summarised in the federal data centre strategy, data centre operators must cover 50% of their electricity use from renewable sources from 1 January 2024 and 100% (on a balance-sheet basis) from 1 January 2027. Bundesregierung / BMDS – Nationale Rechenzentrumsstrategie
The federal government's bill to accelerate implementation of the Energy Efficiency Directive (Bundestag Drucksache 21/8027, 16 September 2026) would amend EnEfG § 11 so that existing data centres must reach a power usage effectiveness (PUE) of 1.6 or lower from 1 July 2027 and 1.4 or lower from 1 July 2030. This is a proposal, not enacted law. Deutscher Bundestag – Drucksache 21/8027 (Gesetzentwurf der Bundesregierung)
At its first reading in the Bundestag on 24 September 2026, the government bill (Drucksache 21/8027) was described as relaxing minimum efficiency requirements for data centres: new data centres would get four instead of two years to meet efficiency requirements, and the 100% renewable electricity requirement would apply from 1 January 2030 instead of 2027. The bill was referred to the Committee on Economic Affairs and Energy. Deutscher Bundestag – Textarchiv
Under § 13(1) EnEfG, operators of data centres with a non-redundant rated connection capacity of 300 kW or more must report data to the federal data centre register (Rechenzentrumsregister), with an annual deadline of 31 March for the previous calendar year. Bundesministerium für Wirtschaft und Energie – Rechenzentrumsregister
On 29 July 2026 the federal cabinet adopted the draft 'Netzanschlusspaket' presented by the Federal Minister for Economic Affairs and Energy; it would move grid connection allocation from purely 'first come, first served' towards 'first ready, first served' and open the way to prioritising grid connections. The ministry names battery storage, data centres and industry among those seeking connections. Bundesministerium für Wirtschaft und Energie – Entwurf Netzanschlusspaket
In a joint position paper dated 5 February 2026, Germany's four transmission system operators stated their intention to introduce a maturity-based allocation procedure (Reifegradverfahren) for transmission grid connections from 1 April 2026, and proposed capacity quotas so that industry, power plants and data centres are adequately considered.
The federal data centre strategy (March 2026) states that grid connection capacity is scarce, particularly in existing hotspots, with long connection times, and that the four transmission system operators alone hold connection requests in the triple-digit gigawatt range for battery storage projects, which compete with data centres for capacity. Bundesregierung / BMDS – Nationale Rechenzentrumsstrategie
In its March 2026 data centre strategy, the federal government states that, as agreed in the coalition agreement, it is pressing the European Commission for data centres to be included in electricity price compensation (Strompreiskompensation), subject to EU state aid rules. Bundesregierung / BMDS – Nationale Rechenzentrumsstrategie
On 9 June 2022 the Frankfurt am Main city council (Stadtverordnetenversammlung) approved proposal M 44, the 'Rechenzentrenkonzept – Aktualisierung des Gewerbeflächenentwicklungsprogramms' (data centre concept updating the city's commercial land development programme). Stadtplanungsamt Frankfurt am Main
According to the Hessian state government, Frankfurt's Rechenzentrenkonzept divides the city's commercial areas into suitable areas, areas of restricted suitability and exclusion areas for non-captive (multi-tenant) data centres. Hessischer Landtag, Drucksache 21/1061 (answer of the Hessian state government)
The Hessian state government states that projects count as spatially significant for regional planning when they exceed the regional plans' mapping threshold of 3 to 5 hectares, and that this is the exception for data centres. Hessischer Landtag, Drucksache 21/1061 (answer of the Hessian state government)
The BMDS National Data Centre Strategy states that 20.1% of data centres in Germany are located in rural areas and 1.4% in structurally weak, very rural areas. BMDS – Nationale Rechenzentrumsstrategie
The BMDS National Data Centre Strategy states that, from the investors' perspective, suitable sites are relatively scarce, particularly in current hotspots. BMDS – Nationale Rechenzentrumsstrategie
The BMDS National Data Centre Strategy names Germany's central location in Europe and its connectivity, including the DE-CIX internet exchange, as location factors. BMDS – Nationale Rechenzentrumsstrategie
According to the Bundesnetzagentur, gigabit-capable connections across all technologies were available to 76.5% of households in Germany in mid-2024. Fibre availability nationwide rose by around 3.5 percentage points in the first half of 2024 to 36.8%. Bundesnetzagentur – press release
According to the Bundesnetzagentur (SMARD), renewable energy sources accounted for 257.5 TWh, or 58.8%, of Germany's net electricity generation in 2025. Bundesnetzagentur – SMARD press release
The BMDS National Data Centre Strategy states that water availability and economical water use for cooling are aspects to be considered for sustainable data centres. BMDS – Nationale Rechenzentrumsstrategie
Germany's target is net greenhouse gas neutrality by 2045, with emissions to be cut by at least 65% by 2030 and at least 88% by 2040 compared with 1990, according to the Umweltbundesamt. Umweltbundesamt – Treibhausgasminderungsziele Deutschlands

Talk to an analystDC Market Insights tracks 170 data centers in Germany as of October 2026: 123 operational, 23 under construction and 24 planned, run by 50 operators. The count grows as we verify more sites.
Tracked operational capacity in Germany is 819 MW, with 1,907 MW under construction and 1,875 MW planned. These totals use the capacity each source states (IT load where given) and cover 82 of 170 tracked facilities.
By tracked operational capacity, the largest operators in Germany are NTT DATA (223 MW), Vantage Data Centers (144 MW) and CloudHQ (112 MW).
The largest clusters by tracked capacity are Frankfurt (82 facilities), Other Germany (26 facilities) and Berlin (15 facilities). The map above shows every site.
We track 1,907 MW under construction and 1,875 MW planned. The largest projects are Hohenhameln (Mehrum) by Telis Energie Deutschland (500 MW), Frankfurt 6 by NTT DATA (482 MW) and Wustermark Campus by Virtus Data Centres (300 MW).
Every facility comes from a page we opened: the operator’s own website or announcement, a stock-exchange filing, a planning or government record, or a named trade publication. A second analyst re-opens the source and checks the name, location, status and capacity before the row is published. We do not copy other data center directories.
We show IT (critical) capacity when the source states it, otherwise the total or utility capacity the source gives, and say which in the facility’s note. When a source gives no capacity, the field stays empty. We never estimate it.
When the source gives an address or coordinates we use them. Otherwise the dot sits at the centre of the facility’s city (marked as approximate), using the GeoNames gazetteer.
The tracker is updated every week as new facilities are announced and existing ones change status. Each row shows the date it was last checked.
Yes. Each country with 50 or more facilities has a Capacity Sheet in Excel with every facility, its source link, the status history and summaries. Our analysts can also prepare an operator extract or a custom cut.
Our analysts prepare country and operator extracts in Excel, capacity pipelines and site-selection briefings.
