Power grid capacity is holding back Germany’s AI data centre growth
Germany’s limited high-voltage grid capacity is slowing AI data centre growth despite strong demand and available investment.
A planned centre in Dummerstorf, Mecklenburg-Vorpommern, was chosen partly because a 380-kilovolt power line runs nearby.
A similar project in Demmin, about 60 kilometres away, fell through because it lacked a way to connect to the high-voltage network.
The grid connection can determine whether a major project goes ahead, as data centres need large amounts of electricity.
Germany’s IT connection capacity is projected to grow from just over 3.3 gigawatts now to about 9.7 gigawatts by 2035, while projections for China and the United States are much higher.
Data centre developers are competing for scarce connections with battery storage projects, electrolysers and other large electricity users.
In April, Germany’s four transmission network operators changed how they assess applications, using project-readiness and network-impact criteria instead of simply granting access in application order.
Germany’s limited high-voltage grid capacity is holding back the expansion of AI data centres, according to n-tv.
The article says developers face long waits for grid connections, which could constrain the sector for at least a decade.
A planned data centre in Dummerstorf was announced with a possible connection to a 380-kilovolt line.
A separate 300-megawatt data centre planned for Demmin fell through because it lacked a high-voltage grid connection.
Germany’s total IT connection capacity is projected to rise from just over 3.3 gigawatts to about 9.7 gigawatts by 2035.
- Who
- Data centre developers and other large electricity users in Germany are seeking connections to the high-voltage grid.
- What
- Limited grid capacity is delaying data centre growth, including AI projects.
- When
- The article was published on 14 November 2026; it says the grid bottleneck could constrain expansion for at least a decade.
- Where
- Germany, including planned data centre sites in Dummerstorf and Demmin.
- Why
- Available high-voltage connections are scarce, and data centres compete with batteries, electrolysers and other large users for access.
This story does not have two clearly opposing sides.
Germany’s four transmission system operators introduced a points-based process to assess applications for new grid connections.
A planned 300-megawatt AI data centre in Demmin fell through because it lacked a high-voltage grid connection.
Mecklenburg-Western Pomerania’s minister-president and the Schwarz Group chief announced a planned data centre in Dummerstorf.
n-tv published its report on grid capacity as a constraint on Germany’s AI data centre growth.
- Dummerstorf investment
- €5.6 billion
- Dummerstorf initial capacity
- 240 megawatts, with potential to grow to 1 gigawatt by 2045
- Demmin project
- Planned 300-megawatt data centre; €1 billion investment
- Germany IT connection capacity
- Just over 3.3 gigawatts currently; about 9.7 gigawatts projected by 2035
- Survey finding
- 91 percent named electricity and grid capacity among their three biggest challenges
What people are saying
The availability of sufficient power connection capacity is currently seen as by far the greatest challenge for the expansion of data centres in Germany.
91 percent of respondents name access to electricity and grid capacity as one of the three biggest challenges.
