Data centers designed around your needs.

From concept to commissioning, every OPCORE data center is engineered in-house, deployed at speed, and built around what you actually need.100% European, sovereign, and AI-ready from day one.

Data centers built for precision.

  • Tech by design

    Our Modular HDD technology redefines how data centers are built by separating the technical infrastructure from the white space. 

    External 1 MW power and cooling modules create a high-precision, industrial-grade system that is as flexible as it is powerful.

  • Customer-centric approach

    Infrastructure that isn’t built around your business is just costly real estate. 

    Our data centers are shaped around your actual technical, design, and MW power requirements.

Manufacturing & Design

Meet HDD, our Modular Data Center Design

Because meeting project deadlines and ensuring lasting performance should never be a trade-off.

What is a modular data center ? 

Our modular data center design (HDD) is built around two external 1 MW units: one for power, one for cooling. 

Together, they form a high-precision industrial system that separates technical infrastructure entirely from the white space.
 

What makes us stand out?

Agile, reusable, and scalable from 1 MW all the way to 250 MW on demand.

By manufacturing modules in parallel with civil engineering works and factory-testing each unit independently, we compress timelines and eliminate uncertainty from the start. 

  • TIME-TO-MARKET OPTIMIZATION

    Less time waiting. More time performing.

    1 MW modules are built in-factory simultaneously with on-site civil works. 

    This parallel production approach drastically cuts deployment timelines compared to traditional construction.

  • TAILOR-MADE AGILITY

    Ready for what’s next. 

    With a global supplier network, emergency sourcing capability, and no reliance on a single supplier, our supply chain is built for continuity.

    That same resilience extends into every configuration: adapting to your workload, not the other way around. 

    Mix cooling technologies, adjust electrical redundancy by 1 MW block, and scale up to 200 kW+ per rack as your requirements evolve.

  • DESIGNED FOR HIGH-DENSITY WORKLOADS

    By relocating heavy equipment (UPS units, cooling groups) into external dedicated modules, interior space is 100% freed up for performance. 

    This means rack densities required by GPU clusters and generative AI workloads are met, not approximated.

  • PERFORMANCE YOU CAN PREDICT

    Predictive behavior, consistent output, and no unexpected surprises.  

    Each 1 MW module is a factory-tested, autonomous unit. Our designs deliver optimal thermal and electrical stability under continuous, critical workloads. 

3 Reasons Why AI Runs Better Here

  • Power capacity & electrical security

    A portfolio of sites with 730 MW secured.

  • Network access & connection timelines

    Direct collaboration with grid operators, RTE, and EDF, combined with proven expertise in fast-tracking permitting.

  • Energy architecture & AI density

    Modular HDD design featuring native air and liquid cooling support. Optimized for GPU clusters and HPC.

Customer-Centric Approach

Easy to upgrade. Built to last. Designed for your workload.

What does this mean?

No two workloads are the same. No two infrastructures should be either. Everything we deliver starts with your actual strategic needs, not a standard template.

What makes us stand out?

A true customer-centric approach is driven by differentiated Service Level Agreements (SLAs). 

We adapt our designs to your actual workload requirements so you don't pay for standards you don't need.

Traditional data center contracts often force you to commit to 40 MW and pay for all of it from day one, even if you only need 1 MW. 

Our modular approach is different. You scale incrementally, commission MW by MW, and your CAPEX matches your actual needs.

  • RAPID DEPLOYMENT

    Speed isn’t a promise here. It’s built into the architecture: prefabricated, reusable containers, EDF fast-track grid connection, and proven permitting expertise to help cut construction time by 2x to 3x.

  • CAPEX & OPERATIONS

    We offer a high-density design combined with sub-market PUE through modular redundancy, minimal retrofit, and module-swap maintenance. 

    And our outdoor infrastructure reduces fire risk and insurance costs while keeping performance built for demanding workloads.

  • EXPERT BY DESIGN

    Our universal, reusable modules scale on demand in 1 MW increments up to 250 MW, meet the diverse hyperscale and GPU compute requirements across Europe.

  • SOVEREIGN & BUILT TO LAST

    Franco-European ownership, low-carbon energy, and bespoke commercial arrangements support infrastructure designed to evolve beyond the next decade of AI. 

    Native DLC support, NVIDIA GB200 readiness, flexible redundancy, and agile upgrades ensure you’re ready for whatever tomorrow brings.

3 Reasons to Love Differentiated SLAs
(Service Level Agreements)

  • Secure full availability

    Ensure maximum availability where data and connectivity are non-negotiable.

  • Optimize redundancy

    Design and adapt redundancy around your actual AI workload needs.

  • Lower CAPEX and significantly lower €/kW recurring costs.

    Cut costs precisely where your infrastructure doesn't need to carry them.

SAFETY & SECURITY

Ensuring the highest level of protection for customer environments and critical IT assets.

What does this mean?

Security and safety are built into every square metre of our infrastructure.

This means multi-layer physical security controls, designed from the ground up to protect customer environments and critical IT assets.

  • What makes us stand out?

    All access requests are pre-registered and formally declared prior to arrival.

    Entry to the facility is secured through a double-gate mantrap system (SAS) with controlled authentication at each stage. 

    Visitors and authorized personnel are welcomed through a dedicated security control desk, where government-issued identification is verified before any access is granted. 

    Biometric fingerprint authentication enforced through individual biometric access mantraps.

    Access rights are strictly role-based, with dedicated authorization required for IT rooms and secured cold corridor areas. This ensures full traceability, full compartmentalisation, and no crossover.

  • Additional Security Measures

    • Dedicated rooms and physically secured cages for customer infrastructure
    • 24/7 video surveillance with retention and audit policies
    • Strong access control policies combining badges and biometrics
    • Full access logging and audit trails for physical and logical access
    • Strict separation of duties between customers, operators, and infrastructure personnel
    • Regular penetration testing, vulnerability assessments, and independent audit
    • Clearly defined incident response and escalation procedures
    • Continuous infrastructure monitoring and centralized logging
    • Business continuity and disaster recovery plans with tested recovery procedures
