European operator Portus Data Centers is developing an additional facility in Munich, Germany.

The company this week announced an expansion of its Munich colocation campus with the construction of an additional 5.5MW facility – Portus Data Centers Munich 2 (MUC2).

The new data center will add 2,200 sqm (23,680 sq ft) of white space and increase the site’s total IT load capacity available to 7MW.

Construction of the new Tier III-quality carrier-neutral data center has already started, with initial capacity set to be delivered in late 2026.

Portus noted the new facility will be fully EnEfG (German Energy Efficiency law) compliant and will cater to workloads ranging from normal power densities to liquid-cooled AI hardware.

“With the investment and expansion at the Munich site, we are not only setting technological but also ecological standards,” said Marco Kain, managing director, Portus Data Centers Munich. “Our new data center is more than just a building – it is a clear commitment to digital sovereignty, sustainability, and innovative strength in Germany. We are creating a platform on which our customers can shape their digital future, securely and reliably.”

Arcus Infrastructure Partners acquired Internet Port Hamburg (IPHH) in December – via its European Infrastructure Fund 3 SCSp (AEIF3) – rolling it into the newly formed Portus alongside previous investments EDH in Luxembourg, and Portus Data Centers Munich (formerly SDC SpaceNet DataCenter).

Adriaan Oosthoek, chairman of Portus Data Centers, added: “Our new development at Portus Data Centers Munich marks an important milestone and aligns with our buy and build growth strategy for the DACH region. It is therefore only a first step, we will continue to add capacity as necessary across the region to meet the strong demand for sustainable high-performance, low-latency IT infrastructure.”

Launched in 2019 and located in Kirchheim, Munich, the former SDC data center offers 5,400 sqm (58,125 sq ft) of data center space with capacity for 2,800 server racks. Portus’ website says the facility currently offers 1.5MW.

Eoghan Cremin, operations director at Mercury Construction commented: “We are proud to continue our partnership with Portus on this significant project following the successful completion of the preconstruction phase. The main contract marks an exciting next step, and we look forward to bringing our extensive experience, innovative approach, and cutting-edge technology to deliver this advanced data center extension in Munich.”

Founded in 1993, SpaceNet AG is an Internet provider and at the time said it will continue to be a long-term customer of the Portus facility, which will house the IT servers and equipment of SpaceNet’s business customers. SpaceNet also operates three other data centers in the Munich area.

Portus recently announced plans to expand its existing sites in Luxembourg and Hamburg.
