Voltekko designs and develops a next-generation network of European data centers, operated according to eco-responsible principles. Our colocation offering meets the most demanding digital needs, including artificial intelligence, the Internet of Things, interconnection, and cloud computing.
Since 2021, Voltekko has been designing and operating a sovereign European network of next-generation data centers, dedicated to AI inference and high-performance cloud applications.
Our infrastructure is built on direct liquid cooling (DLC) technologies, delivering greater energy efficiency than traditional systems, while being located close to major urban centers.
Designed with proximity and digital sovereignty in mind, our “AI-ready” sites provide businesses with a reliable, sustainable, and high-performance environment to host their emerging digital needs at the heart of French and European regions.
Voltekko has established an industrial partnership with Equans, a subsidiary of the Bouygues Group and a European leader in data centers, to design, build, and operate its facilities.
With over 20 years of experience in data centers, Equans meets Voltekko’s requirements in terms of:
Reed – Groupe Société Générale is an investment firm specializing in high-impact technology infrastructure.
A committed player in the emergence of European champions, Reed combines industrial expertise, innovation strategy, and financial strength.
Its support for Voltekko reflects a desire to build a sovereign, sustainable, and high-performance alternative to dominant models, in service of Europe’s industrial and digital transformations.

Energy efficiency Voltekko operates in the rapidly growing sector of next-generation data centers, at a time when these facilities must evolve in terms of power consumption, cooling efficiency, and compliance with increasingly strict environmental regulations.
By making ecological and environmental impact its core focus, Voltekko positions itself as a committed player in the development of next-generation data centers. Every aspect of the design process is aimed at maximizing the efficiency of data center components, from power supply and cooling to water management, security, and high availability.
Each of our data centers targets a PUE of 1.3, thanks to our innovative cooling solutions that combine free cooling, direct liquid cooling (DLC), and immersion, depending on our clients’ specific needs.
The technologies used in Voltekko’s data centers enable a Water Usage Effectiveness (WUE) close to zero, in line with our sustainability goals.
As part of its CSR approach to more responsible digital practices, Voltekko is committed to achieving carbon neutrality by 2030.
Voltekko offers highly secure infrastructure in full compliance with French and European data sovereignty, protecting its clients and their data through its origin, its choice of suppliers, and its data center locations.
Voltekko is designed to support the rise of intensive artificial intelligence workloads.
Our high-density data centers are specifically optimized for hosting AI inference workloads, fully compatible with the latest generations of servers, on sites that are scalable from the ground up.
Thanks to Direct Liquid Cooling (DLC) technology, we ensure stable, high-performance, and energy-efficient operations, with a controlled PUE of 1.2.
Deploying AI models in production? Our infrastructure is ready.
Our data centers are located exclusively in Europe, close to major digital hubs and strategic power grids.
Voltekko offers neutral colocation in a secure, interconnected, and sustainable environment.
With service commitments ranging from 6 to 9 years, our clients rely on stable, controllable infrastructure that is fully aligned with the challenges of digital sovereignty.
Our data centers combine computing power with energy efficiency.
Certified Tier III to III+, they run on 100% renewable energy, achieve a PUE below 1.2, and maintain a WUE close to zero.
The residual heat generated by equipment is recovered and repurposed to reduce environmental impact.
Performance, sustainability, and efficiency are no longer at odds—they form the very foundation of our architecture.
