The project in 30 seconds

One campus, uniting energy and computing power

A colocation data centre campus is being developed as a greenfield project in Schenefeld, Kreis Steinburg, in the Hamburg Metropolitan Region. The site sits in one of the strongest renewable generation regions in Germany. Wind, photovoltaics and battery storage supply the campus, without long grid routes. The offering is aimed at colocation and wholesale tenants, AI and HPC providers, and organisations with high security and compliance requirements.

Design concept · RZ A23 Green Data Campus

The energy advantage

Power is generated where it is consumed

The campus is connected to neighbouring large-scale PV plants and wind farms. Long-term supply agreements provide planning and price certainty over decades, and we pass this cost advantage on to our customers. A battery storage system is planned on site, and use of the campus waste heat is envisaged in the longer term.

Physical connection to neighbouring generation assets. Green electricity from the region, secured via long-term PPAs.

Predictable energy costs

Long-term supply agreements secure conditions over decades. We pass the cost advantages of the site on to our customers.

Short routes instead of grid fees

Generation and consumption sit right next to each other, reducing dependence on long transmission paths.

Genuinely green supply

The power physically comes from the neighbouring plants, not from purchased certificates of origin. This supports ESG and CSRD reporting.

Technology & security

Designed for maximum availability

Availability as a design target

The campus is designed to Tier 4 principles. Redundancy is part of the plan, not a retrofit.

Efficient cooling

Adiabatically assisted air-to-air systems with rainwater harvesting. Highly efficient and resource-conserving in operation.

Ready for AI and HPC

High-temperature liquid-to-chip cooling is planned for dense AI, HPC and GPU workloads.

Physical security

Actively monitored outer perimeter, biometric access control via iris scan instead of badges, mantrap entry and full separation of technical and customer areas.

Fire protection

Automatic early fire detection and suppression systems are part of the building concept.

German data residency

Your systems are located in Germany, and German law applies at the site. As a colocation provider, we have no access to your data.

We are happy to explain further technical and security-related details in a personal conversation.

For tenants

Shape your space before it is built

The campus is at an early project stage, and that is precisely your advantage: space, cages and build-out stages can still be actively tailored to your requirements, with a build-to-suit character and first-mover conditions.

A foundation for your compliance

German data residency, physical security and high availability form the foundation on which you implement your own requirements under GDPR, KRITIS, DORA or BSI C5. As a colocation provider, we operate the infrastructure, not your systems, and have no access to your data.

Scaling without relocation

Capacity grows cube by cube at the same site: from your first space in cube 1 to a full build-out of 17.6 MW IT load.

For tenants

Digital infrastructure with a structural cost advantage

The structural advantage

Energy supply from neighbouring plants on long-term secured terms. A cost advantage that is not easily replicated at other sites.

Scalability

Modular build-out in 4 cubes from 4.4 to 17.6 MW IT load, option for 2 additional cubes. Expansion follows demand, with capital deployment staged accordingly.

De-risking and ESG

A greenfield site without legacy issues, secured energy supply and a clear target standard based on Tier 4 principles. The fully renewable supply via long-term PPAs supports ESG and CSRD reporting.

Detailed documentation is available to qualified parties under a non-disclosure agreement.
