Germany and Europe lag behind the United States and China in data center construction due to an acute shortage of high-voltage grid connections, n-tv.de reported.
While capital and market demand are readily available, the transmission grid operates as a massive bottleneck that threatens to stall artificial intelligence infrastructure development for an entire decade. According to a Bitkom survey cited by n-tv.de, 91 percent of operators and industry experts view the availability of sufficient power connection capacity as the single greatest challenge for building data centers in Germany.
“The availability of sufficient power connection capacities is currently seen by far as the greatest challenge for the expansion of data centers in Germany,” the industry association said, based on survey data published by n-tv.de.
German IT connection capacity is projected to triple from 3.3 gigawatts today to roughly 9.7 gigawatts by 2035, with artificial intelligence and high-performance computing claiming more than half of that power. By comparison, projected capacity will reach 90 gigawatts in China and 160 gigawatts in the United States, according to the report.
Dummerstorf Secures Massive Server Farm Power
The decisive factor for locating major server investments is proximity to high-voltage lines rather than high-speed data networks or customer bases, n-tv.de reported. In late August, Mecklenburg-Vorpommern Minister President Manuela Schwesig and Schwarz-Gruppe chief Gerd Chrzanowski announced plans for one of Germany’s largest data centers in Dummerstorf, near Rostock.
The parent company behind Lidl and Kaufland committed 5.6 billion euros to a server facility starting at 240 megawatts, with expansion potential up to one gigawatt by 2045. The location was chosen because a 380-kilovolt transmission line operated by 50Hertz runs directly through the municipality and is currently being reinforced to carry wind power from the Baltic Sea.
A parallel project planned sixty kilometers east in Demmin collapsed for the exact opposite reason. Despite a one-billion-euro investment plan and 1,250 projected jobs, the site lacked access to the high-voltage grid, leaving the artificial intelligence facility unable to move forward.
Transmission Operators Combat Unprecedented Application Backlog
Grid operators 50Hertz, Tennet, Amprion, and TransnetBW face a massive influx of connection requests from battery storage developers, electrolyzers, and data center operators. Transmission operators held over 700 applications totaling 270 gigawatts at the end of 2025, three-quarters of which came from battery storage developers.
Because existing regulations were designed for a handful of annual applications, operators implemented a controversial maturity-stage process in April. Instead of processing requests on a first-come, first-served basis, a point system evaluates whether applicants have secured land, transmission corridors, equipment contracts, and grid-relief benefits.
Grid operators acknowledged that this meritocratic prioritization “could potentially disadvantage smaller actors or more complex projects,” as reported by n-tv.de. Nearly all available transmission connection points are already reserved for the next five years, with existing applications fully exhausting available capacity well into the 2030s.
The intense competition has spawned secondary markets where connection reservations are traded or strategically hoarded by applicants. In the first application cycle under the new rules, operators received 347 applications totaling 156 gigawatts, vastly exceeding available connection capacity.
Decade-Long Delays Threaten European Tech Expansion
Law firm Gleiss Lutz noted in an analysis that a major share of connection capacity available over the next decade will be allocated during the initial application cycle, leaving little room for subsequent rounds. Connection wait times across Europe average between seven years in Paris, Frankfurt, and London, and ten years in Amsterdam, according to property consultancy Jones Lang LaSalle.
Dublin’s power grid is so heavily congested that authorities barred new connection applications through 2028. In Germany, the federal government’s data center strategy acknowledges the application backlog while aiming to quadruple artificial intelligence computing power by 2030.
The federal network package designed to support the grid operators’ maturity-stage process faces legislative delays in the Bundestag amid political disputes over wind and solar park curtailment rules. Even projects that successfully secure grid connections face lengthy construction timelines, with the Schwarz-Gruppe facility in Dummerstorf targeting construction in late 2027 or early 2028 and operations beginning in 2032.
Frequently Asked Questions About Germany’s Power Grid Bottleneck
Why are battery storage developers applying for so many grid connections?
Battery storage developers submitted three-quarters of the grid connection applications logged by transmission system operators by the end of 2025, exceeding original network development plans as investors seek storage capacity for renewable energy generation.
When will new grid connection points become available in transmission zones?
According to provisional estimates cited by n-tv.de, the next available grid connections at Tennet substations will open around 2030, while TransnetBW and Amprion connections are not expected until 2032 at the earliest.
How is the German government responding to the data center bottleneck?
The federal government intends to quadruple artificial intelligence computing capacity by 2030 while establishing a legal framework through a proposed network package, though parliamentary votes on the legislation have faced repeated delays.
