German data center firm Maincubes is expanding its presence in Frankfurt with a new facility.

Located in the Rhine-Main metropolitan area, south of Frankfurt in Dietzenbach. FRA04 will provide approximately 12,500 square meters (134,550 sq ft) of whitespace and 40MW of IT capacity.

Maincubes said it has acquired the site with a committed power of 60MW. The facility is due to go live in 2027.

"Maincubes stands out from other providers for several reasons," Oliver Menzel, CEO of Maincubes, said. "First, as a European company, we are independent and capable of offering the best solutions for data protection and data sovereignty. Second, we understand that efficiency and sustainability are crucial factors for organizations in the hyperscaler and artificial intelligence sectors when selecting a data center. With our successful Eco-Management and Audit Scheme (EMAS) registration and the implementation of the ESG framework according to GRESB, we not only meet current customer requirements but are also prepared for future EU regulatory requirements for data center operators."

Maincubes currently operates the FRA01 data center in Frankfurt and another in Amsterdam in the Netherlands. The company is majority-owned by Digital Transformation Capital Partners (DTCP).

In 2015, Keppel DC REIT acquired a then yet-to-be-constructed Maincubes data center in Offenbach, outside Frankfurt.

The company broke ground on a second Frankfurt facility in July 2022, and the same year announced plans for a third facility in Frankfurt and its first in Berlin.

Earlier this year Maincubes secured more than €1 billion ($1.07bn) in debt financing to fund its expansion plans. The company says it has a portfolio with more than 100MW of capacity in operation or development as well as more in the pipeline.
