The market is projected to reach USD 2.06 billion by 2035, a CAGR of 14.49% from 2025. **How fast is the Belgium Data Center Infrastructure Market growing?** 14.49% a year from 2025 to 2035, after 22.22% a year from 2020 to 2025, as new IT capacity rises from 45 MW in 2025 to 110 MW a year by 2030 (DC Market Insights). **How much does data center infrastructure cost per MW in Belgium?** About USD 8.85 million (EUR 7.83 million) per MW of new IT capacity in 2025, between LCL's EUR 5.00 million and the Proximus sale's EUR 11.64 million per MW, plus USD 0.40 million per installed MW a year for upgrades (DC Market Insights). **How much data center capacity does Belgium have?** About 380 MW of IT capacity at the end of 2025 in DC Market Insights' model, consistent with the 3.2 TWh of data center consumption Elia reports. The base case reaches about 813 MW in 2030 and about 1,372 MW by 2035. **Why is Saint-Ghislain the largest data center site in Belgium?** USD 165.38 million of 2025 infrastructure spending: Google runs its Belgian campus there and plans EUR 5 billion more through 2027. DC Market Insights expects USD 867.21 million of spending at Saint-Ghislain by 2035. **Which segment of Belgium data center infrastructure grows fastest?** Racks above 40 kW, at 29.77% a year to USD 867.21 million by 2035, because AI halls need liquid cooling and heavier power trains. Electrical infrastructure stays the largest component at 28.68% of 2025 spending. **Which region of Belgium grows fastest in data center infrastructure?** Hainaut, at 17.75% a year to USD 929.16 million in 2035, almost all of it at Saint-Ghislain. The Brussels Metro area still holds 40.00% of 2025 spending. **Who are the key companies in Belgium data center infrastructure?** Schneider Electric, Vertiv, ABB, Siemens and Eaton supply about 44% of electrical and cooling equipment value (DC Market Insights estimate); Google, Microsoft, LCL Data Centers, Datacenter United and Digital Realty are the main buyers. **How do grid rules affect Belgian data center infrastructure spending?** CREG's 29 January 2026 code sets build deadlines on reserved grid capacity, so developers must order equipment on time or lose it. DC Market Insights expects 60 MW of new capacity in 2026, against 30 MW in 2024. **Why do Belgium Data Center Infrastructure Market estimates differ?** USD 698.27 million in 2026 is the DC Market Insights figure for facility infrastructure only. Estimates that add servers, GPUs and networking, or size the market from Elia's connection queue, land several times higher. ## Dataset | Series | Value | Unit | | --- | --- | --- | | Market size 2025 | 533.49 | USD million | | Revenue CAGR | 14.49 | % | | Market size 2035 | 2,060 | USD million | ## Frequently asked questions ### What is the size of the Belgium Data Center Infrastructure Market in 2026?
