Digital Realty BER2 Berlin Data Center Campus
Status: Under Development / Active Phased Buildout | Location: Strategic Industrial Hub, Greater Metropolitan Berlin Area, Germany
Project Overview
A next-generation hyperscale and cloud-neutral data center campus purpose-built to support demanding artificial intelligence (AI), cloud computing, and enterprise workloads through high-density, scalable infrastructure. Designed to meet the evolving requirements of hyperscalers, cloud service providers, and large enterprises, the campus features advanced power and cooling systems capable of supporting high-performance GPU clusters and next-generation AI applications. The facility incorporates sustainable engineering practices, including heat-reuse technology that captures excess server heat and redistributes it to nearby buildings or district heating networks, improving overall energy efficiency and reducing carbon emissions. Carrier-neutral connectivity provides customers with direct access to multiple telecommunications providers, internet exchanges, and leading cloud platforms, enabling low-latency, resilient, and highly interconnected digital operations. Built with redundant power architecture, advanced physical security, and modular expansion capabilities, the campus ensures high availability and operational reliability for mission-critical applications. Its flexible design accommodates future growth while supporting hybrid cloud deployments, high-performance computing (HPC), big data analytics, and other compute-intensive workloads. By combining AI-ready infrastructure, sustainable heat-reuse integration, resilient engineering, and extensive interconnection capabilities, the campus serves as a strategic digital hub for organizations seeking scalable, energy-efficient, and future-proof infrastructure to accelerate digital transformation and support the rapidly growing demand for advanced computing services.
