BER02: Connected, Powered, Ready to Grow
Perfectly Located
Berlin – led by BER02 – is rapidly emerging as Europe’s Tier II hub. Strategically located to provide geo-redundant support for Frankfurt, it is close to federal institutions, new availability zones, and emerging data center clusters. Powered by local wind and solar energy, our campus offers a prime location with access to verified renewable energy sources – ensuring performance and compliance from Day 1.
Quickly Deployed
Developed by a German provider with deep local expertise, BER02 brings together our operational experience and regional insight to accelerate delivery. Our proven track record in managing complex processes enables us to realize large-scale, high-density deployments faster and more predictably. With technical agility and modular design flexibility, the site provides an ideal foundation for next-generation workloads — from AI to high-performance computing.
Sustainably Designed
Sustainability is at the core of BER02 – in every phase, from planning to execution. The whole campus is engineered to meet the highest ESG standards, with design features that include renewable energy integration, LEED certification, zero process water usage, and extensive greening. This comprehensive approach helps you meet your environmental targets while maintaining a sharp focus on cost efficiency and long-term value. BER02 is not just future-ready – it’s future-responsible.
“With BER02, we’ve created a modular, future-ready infrastructure that allows us to tailor solutions precisely to our customers’ evolving needs – from power density to cooling and deployment speed.”
