The owner of Lidl is preparing to spend up to €5.6 billion on
something that has little to do with supermarket shelves: a giant data
centre for cloud computing and artificial intelligence.
Schwarz Group, the German company behind Lidl and Kaufland, announced
on 27 August 2026 that it wants to build the facility at Dummerstorf,
near Rostock in northern Germany. Subject to permits, the site is
planned to reach 240 megawatts of grid-connection capacity by 2033, with
a possible expansion to one gigawatt by 2045.
This is not simply a retailer buying more servers. It is a sign that
the infrastructure beneath AI is becoming important enough for large
non-technology companies—and governments—to treat computing capacity
almost like power generation, logistics or telecommunications.
Why is a
supermarket owner building a data centre?
Modern retail is already a digital business. Large chains depend on
software for inventory, pricing, payments, online orders, warehouse
automation, cybersecurity and the movement of goods between thousands of
stores.
Schwarz Group has built a separate digital division, Schwarz Digits,
whose services include cybersecurity, artificial intelligence and the
STACKIT cloud platform. STACKIT
says it began as the internal cloud for Schwarz Group and now offers
European businesses and public bodies an alternative to large overseas
cloud providers. It stores and processes customer data in Europe and
uses open-source technologies to reduce dependence on a single
proprietary system.
The new Dummerstorf data centre would support Schwarz Group’s own
digital operations while giving Schwarz Digits more room to expand its
cloud and AI services. In other words, the company is trying to turn
infrastructure it needs for Lidl and Kaufland into a broader commercial
platform.
That makes the surprise easier to understand. Amazon also grew from
retail into cloud infrastructure, although Schwarz Group is starting
from a much smaller technology base and has not claimed it can match
Amazon Web Services, Microsoft Azure or Google Cloud globally.
A 240-megawatt
project—with a much bigger option
According to the company’s
announcement, Schwarz Group expects the planned 240-megawatt
facility to cost about €5.6 billion. Construction is intended to begin
in 2027, and Reuters
reported that the complex is expected to create around 120 permanent
jobs.
The megawatt figure describes the scale of the site’s potential
electrical connection, not a promise that it will continuously consume
240 megawatts from its first day. Actual demand will depend on the
number and type of servers installed, how heavily they are used, cooling
conditions and the pace at which the campus is built out.
The one-gigawatt figure is more distant still. Schwarz Group
describes it as an expansion opportunity by 2045, not committed
operating capacity. A one-gigawatt connection would place the campus
among the largest proposed computing sites in Europe, but demand,
financing, permits and grid development would all have to support that
growth.
Technical details remain unresolved. The company explicitly says the
project is at an early stage and that the final mixture of cloud and AI
chips has not been decided. That distinction matters: this is a major
infrastructure commitment, but it is not yet a completed AI
supercomputer.
Why Dummerstorf offers power, cooling and heat-reuse options
Dummerstorf offers three resources that are increasingly difficult to
secure for AI infrastructure: electricity, grid access and cooling.
Northern Germany has extensive onshore and offshore wind generation.
The proposed industrial site can also connect to a 380-kilovolt
extra-high-voltage network, which is designed to move large quantities
of electricity efficiently. Schwarz Group says electricity used in
normal operations is intended to come exclusively from renewable
sources.
The cooler regional climate can support “free cooling,” in which
outside air helps remove server heat and reduces the amount of
mechanical refrigeration required. The company says it plans modern air
cooling rather than relying on large volumes of water for routine heat
removal.
Schwarz Group has also signed a letter of intent with Rostock’s
municipal utility to explore feeding waste heat from the servers into a
district-heating network. That could turn heat normally released into
the environment into useful energy for buildings. However, it remains a
proposal: the heat network and customer connections would still need to
be engineered and financed.
Europe’s push for “digital
sovereignty”
The wider goal is what European policymakers call digital
sovereignty—the ability to run important cloud services and AI systems
under European law, with greater control over where data is stored and
who can access it.
The European Commission’s Cloud
and AI Development Act programme aims to at least triple EU
data-centre capacity within five to seven years. It also proposes faster
permitting, better access to land, power and finance, and a common
framework for assessing sovereign cloud services.
Separately, the EU is building a network of AI
Factories and proposed AI Gigafactories. The planned gigafactories
are intended to combine more than 100,000 advanced AI processors with
high-capacity networking and power infrastructure.
Schwarz Group’s plan fits that political direction, but “sovereign”
should not be confused with completely self-sufficient. Europe still
depends heavily on processors, manufacturing equipment and software
developed elsewhere. The chips for Dummerstorf have not even been
selected. A German data centre can improve control over operations and
data jurisdiction without eliminating every overseas dependency.
What this project really
shows
The most important part of the announcement may not be its headline
price. It is the identity of the builder.
Cloud and AI infrastructure is moving beyond a small club of American
technology giants. Retailers, telecommunications companies, industrial
groups and governments increasingly see computing capacity as strategic
infrastructure. Companies with large balance sheets, electricity access
and existing digital workloads can now make a credible attempt to become
cloud operators themselves.
For Schwarz Group, the project could provide greater control over its
own systems and create a new business serving organisations that want a
European cloud. For Germany, it could add a large domestic computing
hub. But neither outcome is guaranteed: permits, construction, customer
demand, chip supply and grid capacity will decide whether the
240-megawatt plan—and the far more ambitious one-gigawatt option—become
reality.
The announcement is therefore significant without needing
exaggeration. Lidl’s parent has not suddenly become an AI leader. It has
made a costly bet that the physical infrastructure beneath AI will be as
strategically important to Europe as the software running on top of
it.
The proposed heat link has a wider context: explore how data centre waste heat can warm buildings through district heating.
