Colt Data Centre Services (Colt DCS) has started work on a new data center in Berlin, Germany. “We’re proud to celebrate the groundbreaking of Colt Data Centre Services' new development in Berlin, marking an exciting milestone in the delivery of critical infrastructure for one of Europe’s leading data center companies,” H&MV Engineering said in a LinkedIn post this week. As part of the project, H&MV is delivering a 110 kV G.I.S substation. Colt announced plans for Berlin 1 and 2 in April 2025 . The two data centers will be constructed on a 9.5-acre site 10km east of the capital and will provide a total of 54MW of IT capacity, with Berlin 1 due to go live by the end of 2028. Founded in 1992 and originally known as City Of London Telecom, Colt was acquired by Fidelity Investments in August 2015. Colt DCS’ portfolio includes 15 operational data centers, with around a dozen sites under development across the UK, Europe, and the APAC region. The company says it has nearly 800MW of capacity under development. The company currently has three German data centers, all located in Frankfurt, with two more in development around the city. Colt previously operated legacy facilities in Berlin and Hamburg, but these were sold as part of a larger European portfolio to AtlasEdge in 2021 .
