VIRTUS INSTALLS TWO OF EUROPE’S LARGEST SUPER-GRID TRANSFORMERS AT WUSTERMARK CAMPUS IN BRANDENBURG

Campus to be the first in Berlin/Brandenburg to operate as a closed distribution network

BERLIN/BRANDENBURG, Germany – 1st June 2026 – VIRTUS Data Centres (VIRTUS), an award-winning pure-play data centre developer and operator and part of ST Telemedia Global Data Centres Group, has announced the successful delivery and installation of two 185MVA super-grid transformers at its Wustermark Campus in Berlin/Brandenburg.

Among the largest ever deployed in a European data centre, the transformers mark a significant milestone in the campus’ development. Wustermark will be the first data centre campus in Berlin/Brandenburg to connect at 380kV, providing customers with the option of operating a groundbreaking zero-generator model.

The transformers form a key part of the campus’ initial 300MW capacity, designed to scale over time. Power is delivered via a dedicated 500MW substation, with dual direct connections to the 50Hertz 380kV transmission network. Integration with the 50Hertz Wustermark substation (Umspannwerk), combined with these high-voltage connections, provides a highly stable and resilient power architecture. 

The stability, reliability, and mesh distribution topology of the 380kV network, supported by multiple renewable infeed points, delivers industry-leading resilience and uptime. The site is designed with diesel generator capacity as standard, providing customers with the capability to operate with generators. For those seeking greater sustainability, a zero-generator configuration is also possible. This flexibility enables customers to significantly reduce carbon emissions and long-term operational costs when they choose, setting a new benchmark for sustainable data centre design.

As with all VIRTUS data centres, the site will operate on 100% certified renewable energy. The Berlin/Brandenburg campus is closely integrated with regional renewable energy sources, including substantial onshore wind capacity. This enables customers to reduce their reliance on fossil fuel-based backup systems while contributing to Europe’s decarbonisation goals.

Operating at higher voltages than traditional distribution transformers, these oil-filled, transformers deliver:

  • Enhanced resilience
  • Improved electrical efficiency
  • Superior system stability for AI workloads
  • Reduced transmission losses

This design also provides customers with lower system usage charges and meaningful operational cost efficiencies, particularly critical as energy costs become an increasingly dominant factor in long-term data centre operations.

Mike Golding, SVP of Construction at VIRTUS Data Centres, said: “Delivering the Wustermark Campus has been one of the most ambitious engineering programmes 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 note 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.
