A state-of-the-art, sustainable data center will soon be built in Schwalbach am Taunus, in direct line of sight to DCG’s Frankfurt office. The contract, worth several million euros, complements the record order intake of the current financial year and strengthens DCG’s position as one of the leading providers of holistic data center solutions in the DACH region.

This project sees DCG bring a forward-looking green data center from the stage of data center design and engineering to execution. The necessary approvals, including the building permit and the permit under the Federal Immission Control Act (BImSchG), have already been granted. Construction will begin in April 2026.

“This major contract is a strong signal of the capabilities of the DCG team and the trust placed in our expertise by national and international players. At the same time, it confirms our commitment to consistently developing, data center design an engineering, implementing and advancing sustainable and future-proof data centers,” explains Ralf Siefen, CEO of Data Center Group. 'We are particularly pleased to realise such an important project in the immediate neighborhood of our Frankfurt office.'

Focus on sustainability and efficiency

The new data center embodies a consistent commitment to sustainability in its construction and operation. Plans include using waste heat and 100% green electricity, as well as integrating photovoltaic systems into parts of the facade and the site to reduce electricity purchases. Charging stations for electric vehicles in the vicinity of the data center are planned in cooperation with the city to promote sustainable mobility in the region. A wooden and green facade ensures natural cooling and harmonious integration of the building into the landscape.

With a planned IT load of 20 megawatts and a connection capacity of 25 to 30 MVA, powerful infrastructure is being created to meet the highest demands. A targeted energy efficiency value (PUE) of 1.2 underscores the commitment to achieving maximum energy efficiency.

High-performance infrastructure for the digital future

The data center will be designed according to the DIN EN 50600 standard in availability class 3 to offer the highest level of reliability and flexible usage options. Around 7,000 m² of IT white space will house state-of-the-art server areas in redundant fire compartments.

A carrier-neutral connection with redundant fiber-optic infrastructure and proximity to the DE-CIX internet exchange ensure optimal connectivity. Additionally, a comprehensive security concept, state-of-the-art flexible cooling systems, and the ability to integrate innovative technologies (including AI applications) ensure long-term viability.

Strong contribution to digital and sustainable development

With the new project in Schwalbach am Taunus, DCG is establishing another sustainable data center in one of Europe’s most important digital regions. The project's combination of high-performance infrastructure, sustainable operations, and strategic location makes it a key building block for the digital future.

"Together with our clients and end customers, we are shaping the digital infrastructure of tomorrow — efficient, sustainable, and high-performing. This project is an outstanding example of that,” says Siefen.
