Kick-off for the construction of the next firstcolo location: The management received the official building permit for the planned data center at Rosbach Town Hall.
Frankfurt/Main / Rosbach vor der Höhe, February 2026. For the city, it is a significant step towards a digital future: the creation of a new data center in Rosbach vor der Höhe. January 29 marked the start of the construction project. Birgit Weckler, First District Deputy of the Wetterau district, ceremoniously presented the official building permit to the operator, firstcolo Datacenters GmbH from Frankfurt am Main, at Rosbach Town Hall.
In the presence of Rosbach’s Mayor Steffen Maar and Mathias Radu, an employee of the district building authority, the entire firstcolo management – Jerome Evans, Nicolaj Kamensek, and Dennis Bergfeld – received the document with great pleasure. Denis Grosch, Head of Urban Planning and Real Estate, Nils Schellhammer, Economic Development, Urban Development, Climate Protection Strategy, and Sebastian Briel, Head of the Mayor’s Staff Office, also supported the official handover with their participation.
With the new data center, firstcolo is realizing the region’s largest construction project: a state-of-the-art data center designed for AI applications, with a total area of approximately 18,000 m² across multiple levels and a capacity of up to 24 megawatts, is to be built on a plot of 11,555 m². The total investment amounts to approximately 250 million Euros.
“With the construction of our data center in Rosbach, we are taking the next step towards a new generation of high-performance data centers,” explains Jerome Evans, founder and managing director of firstcolo. “Like all our locations, this one will also be operated 100 percent with renewable energies. We aim to build one of the most energy-efficient data centers in Germany.” The planned data center combines state-of-the-art technology with sustainable concepts: in addition to 100 percent green electricity supply, the use of innovative cooling technologies, and effective utilization of waste heat, particularly low PUE values are targeted. (Note: PUE stands for Power Usage Effectiveness and indicates how efficiently a data center uses energy: the lower the value, the better). The offering will include flexible usage options from single racks to customer-specific IT spaces, and connectivity will feature a carrier-neutral connection and triple-redundant fiber optic connectivity.
First District Deputy Birgit Weckler emphasizes the project’s importance for the Wetterau region: “Today, data centers are a central building block and the physical foundation of our digital infrastructure. They enable innovation and thus strengthen our economic competitiveness. It is a strong signal for the city and also for the entire region that such a project is now being realized in Rosbach. It shows that the Wetterau district is an attractive and future-proof location for key digital technologies.”

The project is not only intended to provide digital infrastructure for companies in 33 countries; it also offers real added value for the city of Rosbach: the generated waste heat will be available for free for 20 years, for example, for a planned local heating or district heating network. “The more powerful the server systems operate, the more waste heat a single server cabinet generates. As a company from Hesse, we are locally rooted and want to be an asset to the city: firstcolo will provide the heat from the data center to the city free of charge for 20 years, thereby strengthening Rosbach as a growth-oriented location,” says Evans. Ultimately, digital infrastructure today is on par with traffic planning and energy supply, securing future viability.
The completion of construction is planned for the end of 2027, so that Rosbach can soon host a high-performance, sustainable data center in the heart of Europe. Mayor Steffen Maar and the city of Rosbach are satisfied: “The granting of the building permit is a decisive milestone for the economic development of our city. We are not only creating the basis for future tax revenues but, above all, highly qualified jobs for specialists in a future-oriented industry. My thanks go to the management of firstcolo for this clear commitment to our location and also to our administrative team, which recognized this opportunity early on and professionally supported the project until it was ready for approval.”
