Deploy AI infrastructure.

Fast. Green.

  • Electricity availability is now the #1 limiter to deploying AI compute, with grid queues reaching 5–10 years across Europe (ENTSO-E, 2024).

    Many regions cannot deliver the 10–200 MW blocks required for modern GPU clusters.

    With its innovative power-first approach, Calcore deliver in record-time.

  • AI workloads are driving data center electricity demand up 30% per year (IEA, 2024).

    Regulators and customers now expect low-carbon power and heat-reuse, which can recover 90–95% of wasted energy (ASHRAE TC9.9).

    Calcore designs for climate-positive operation from day one.

  • Europe is enforcing stricter rules on data center energy efficiency, reporting, and heat integration (EU Energy Efficiency Directive, 2023).

    Operators are required to provide transparency on PUE, water use, and waste-heat potential.

    Calcore helps you anticipate this shift.

Energy-first locations

Forget about 1+GW campuses. Skip the multi-year grid interconnection delays. Calcore adopts a multi-site deployment strategy: we select energy-rich sites with on-site or near-site generation, ensuring instantly deployable capacity from 10 MW up to 100+ MW.

Our infrastructure is

Purpose-built for AI

AI workloads demand extreme rack densities. Calcore sites are engineered for 150+ kW/rack, full liquid-cooling, and Blackwell-ready electrical architectures.

We also design for higher-density GPUs (Rubin, Feynman) or specific ASICs generations, with 500kW+/rack and VDC electrical distribution in mind.

Designed for high-densities

Our infrastructure is built around repeatable, containerized modules — standardized units that deploy fast.

From a single SU (1.2 MW) to multi-megawatt clusters, every Calcore site expands seamlessly.

Modular and scalable

Green and integrated

Our infrastructures are designed to run on low-carbon energy from day one: biomass turbines, hydro, or nuclear-based grid mixes. We also recycle >50% of the heat produced by our data centers, by colocating our infrastructures with Heat District Networks (HDN) or industrial sites (e.g., greenhouses).

We make every watt count, enabling some of the lowest CO₂footprints in the industry.
