Investments in German data centers are experiencing a massive acceleration in 2026. The digital association Bitkom, in partnership with the Borderstep Institute, released its study on November 3, 2026, examining figures, trends, and perspectives in an international comparison. According to the report, capital expenditure on data center infrastructure across Germany is climbing by 57 percent this year, reaching 23.5 billion euros. In the previous year, total investment stood at 15 billion euros.
An examination of capital distribution reveals that hardware purchases command the bulk of these budgets. Approximately 18 billion euros of this year's total capital expenditure is allocated directly to IT hardware, including servers, dedicated AI accelerators, and high-capacity storage. Building construction and physical infrastructure absorb the remaining 5.5 billion euros. This spending pattern underlines the urgent priority operators place on procuring high-density compute systems required for modern model execution.
The shift in operational workload types represents the core engine behind this hardware expansion. Artificial intelligence and high-performance computing workloads already occupy 20 percent of total German data center capacity in 2026. Projections calculated by the authors indicate that this proportion will expand to 55 percent by 2035. As training and inference pipelines scale, traditional computing tasks are increasingly eclipsed by compute-intensive frameworks.
This architectural transformation brings substantial consequences for national grid capacity and power supplies. The required grid connection capacity for German facilities is climbing from 3,300 megawatts today to a projected 9,700 megawatts in 2035. Dedicated connection capacity strictly serving AI workloads will jump from 670 megawatts to 5,300 megawatts. Consequently, annual power consumption is on track to nearly triple from 23 billion kilowatt-hours in 2026 to between 56 and 70 billion kilowatt-hours by 2035.
Despite this strong domestic momentum, the study illustrates a growing competitive disparity on the global stage. While total data center capacity across all of Europe is projected to reach only 37 gigawatts by 2035, the United States is advancing toward 160 gigawatts. China is expanding its footprint rapidly as well, with projections pointing to 90 gigawatts by 2035. While Germany commits record capital, European digital infrastructure continues to lose market ground internationally.
