ParTec AG: ParTec AG and 3D Lézertechnika Zrt. sign a letter of intent for a modular hyperscale AI data center, a solar park, and energy storage as part of a European flagship project in Central Europe - Setting New Standards for Innovation and Sustainability

Munich/Budapest, July 8, 2025 – ParTec AG (ISIN: DE000A3E5A34 / WKN: A3E5A3) and the Hungarian company 3D Lézertechnika Zrt. have signed a letter of intent to implement one of the largest AI and energy infrastructure projects in Central Europe with multiple billions EUR investment volume. The “Paks Data Centre Campus, BESS & Agro-Photovoltaic Energy Park” project combines a state-of-the-art modular hyperscale AI data center with sustainable energy generation, innovative storage technology, and strong roots in the Hungarian HPC, AI, and quantum computing landscape. ParTec AG will deliver the hyperscale AI-Data Center with quantum computing integration possibility.

The location near the Hungarian nuclear power plant in Paks combines three important elements. At its heart is a next-generation modular AI data centre with a power consumption of up to 96 MW, designed for hyperscale and AI-focused data processing. In addition, a large agro-photovoltaic park will be built on an initial area of 530 hectares to generate solar power for the AI data centre. A powerful battery system also ensures power grid stability and a continuous and sustainable supply of power. The immediate proximity to the power plant also guarantees a particularly efficient and flexible energy supply. The waste heat from the data centre will be used in a sustainable way for the adjacent agricultural operations - energy production and agriculture go hand in hand.

The project is closely linked to Hungary's highly innovative and dynamically growing AI and quantum computing landscape. With its central location in Europe, favourable tax and energy conditions, and a large pool of highly trained specialists, Hungary offers an attractive location for the project.

ParTec AG is contributing its over 25 years of expertise and proven technology in high-performance computing, AI and quantum technology, thereby strengthening Europe's digital sovereignty. The modular AI data center will be based on ParTec’s dynamic Modular System Architecture (dMSA). Additionally, it will include ParTec’s ParaStation Modulo Software Suite. Both combined, allow for speed, scalability, flexibility, and efficiency. Furthermore, ParTec will be responsible for potential quantum computing integration. Due to its technologies, ParTec’s quantum technology integration is hardware agnostic. The regular operation of the data centre is scheduled to begin in 2027.

With an investment volume in the single-digit billion range, the project underscores its central strategic importance for future development in the field of high-performance computing, AI and quantum computing technologies. A significant part of the investment will go toward expanding and establishing the infrastructure, which will be carried out primarily by 3D Lézertechnika Zrt. ParTec AG is responsible for the delivery and integration of the supercomputer systems. This part of the project will be financed by ParTec AG in cooperation with a strategic financing partner with whom ParTec is already in advanced negotiations to create additional planning security and accelerate the implementation of the overall project.

Bernhard Frohwitter, CEO of ParTec AG, says: "We are combining green energy, modular infrastructure, and leading AI computing power to create a European flagship project. With the Paks Data Center Campus, we are creating a highly efficient and scalable infrastructure for data-intensive applications while setting new standards for sustainability and energy efficiency in data center operations. This project exemplifies our vision of a sovereign European digital and technology landscape that combines ecological responsibility with technological excellence.”

Prof. Dr. László Palkovics, Hungarian Government Commissioner for Artificial Intelligence, explains: “With the Paks Data Center Campus, Hungary is becoming a hub for Europe's digital future. Our joint project combines technological innovation with energy-efficient agriculture, while promoting regional development and representing progress, sustainability, and regional development, as well as the future viability of Hungary's infrastructure and innovation landscape—supported by the Hungarian government and driven by a shared vision for AI and energy efficiency.”

Background:

This announcement is the third AI-Data Center project ParTec has made public in the recent months, after ELBJUWEL in Germany and VESUVIO in Italy. ParTec is a key technological partner in some of Europe’s most powerful supercomputers. The latest one is JUPITER, Europe’s first Exascale Supercomputer. It is the 4^th fastest in the world, and the most energy-efficient one among the first 5 in the top500 list.

About ParTec

ParTec AG specializes in the development and manufacture of supercomputers for high-performance computing and AI based on its modular high-performance computing (HPC) systems and quantum computers (QC) as well as the associated system software. Its offering also includes consulting and support services in all areas of the development, construction, and operation of these modern systems. The concept of dynamic modular system architecture (dMSA) is the result of more than fifteen years of research and was developed by ParTec as a novel system design for massively parallel high-performance systems. The dMSA and the underlying ParaStation Modulo software suite, developed, supported in production and maintained by ParTec, have proven particularly well suited to the complex requirements of massive computing power in AI.
