Virtus Data Centres has installed two 185MVA super-grid transformers at its Wustermark Campus in Berlin/Brandenburg, Germany.

According to the company, the transformers are amongst the largest ever to be deployed at a European data center, and represent a key moment in the campus’s development, becoming the first campus to connect at 380kV.

The transformers will support power delivery at the campus, which is expected to have an initial capacity of 300MW and scale over time. Power will be delivered to the data center via a 500MW substation, with dual direct connections to the 50Hertz 380kV transmission network. Virtus claims that the high-voltage connections will support a highly stable and resilient power architecture.

Virtus has said that the site will operate on 100 percent renewable energy and will be closely integrated with regional renewable energy sources, including substantial onshore wind capacity.

Commenting on the news, Mike Golding, SVP of Construction at Virtus, said: “Delivering the Wustermark Campus has been one of the most ambitious engineering programs Virtus has undertaken to date. From the 380kV connections to the deployment of these super-grid transformers, every element has been designed to deliver levels of resilience and scalability that have not previously been available in this region.

“This campus represents a new generation of infrastructure – one that supports AI-scale growth, reduces reliance on generators, and aligns with the future of renewable energy. We are incredibly proud of what our teams and partners have achieved, and this is only the beginning of our long-term commitment to the Berlin-Brandenburg region.”

The company broke ground at the data center last month. The site is situated 2km (7.4m) west of the capital in the municipality of Wustermark, with Virtus expected to invest €3 billion ($3.5bn) in the project.

The campus will cover approximately 3.7 million sq ft (350,000 sqm) and comprise nine separate data centers, with waste heat from their server rooms diverted to a district heating scheme in the nearby Havelland and Potsdam regions. All units will include high-density rack support and closed-loop chilled water cooling systems to support high-performance computing and AI applications. Power to the complex will be supplied, in large part, by several nearby onshore wind farms.

Founded in 2008, Virtus is headquartered in the UK and currently operates four data center campuses in the country, clustered in the Greater London area. Other campuses are planned for Buckinghamshire in central England and Milan in northern Italy.

The operator also broke ground last year on another campus in Berlin’s Marienpark business park. Smaller than its counterpart in Wustermark, the complex will host four data centers supplying 57.6MW of IT load across 204,515 sq ft (19,000 sqm) and is expected to open for business in 2027.
