Maincubes Breaks Ground on Major 200MW Data Center Campus Near Berlin
March 25, 2026
The strategic expansion of data center capacity in the Berlin metropolitan region has taken a significant step forward as German operator Maincubes has commenced construction on its second major campus in the area. This development underscores the continued growth of the German capital as a critical digital infrastructure hub in Europe, driven by increasing demand for cloud, AI, and enterprise computing services.
Maincubes this week held a groundbreaking ceremony in the town of Nauen, located west of Berlin, marking the official start of work on its BER02 campus. The company stated, “With the official start of construction for the substation and the cable route, we have reached an important milestone for our new data center campus in Nauen.” The initial phase of the campus is scheduled to launch in December 2027.
The new facility is designed with a total power capacity of 200 megawatts (MW), with future infrastructure plans allowing for potential expansion to 400MW. Maincubes secured the land for this project in October 2024 and publicly announced its development plans the following year. This new campus complements the company's existing footprint in the region, which includes the BER01 facility in Berlin's Schmargendorf district. That single-tenant site offers 8.3MW of IT power across 5,100 square meters (54,895 square feet).
Founded in 2012 and headquartered in Frankfurt, Maincubes is majority-owned by investment group DTCP. Its current operational portfolio includes one data center in Amsterdam and three in Frankfurt, with a fourth Frankfurt facility planned. The launch of the BER02 campus represents a substantial scaling of its presence in Northern Germany.
The development is poised to significantly bolster digital infrastructure resilience and capacity in the Berlin-Brandenburg region. By providing a large-scale, scalable campus with dedicated power infrastructure, Maincubes aims to cater to the needs of hyperscale cloud providers and large enterprises seeking colocation space in a key European market. The project also highlights the trend of data center development extending into areas surrounding major cities to access available land and power resources.
