Denmark in detail

What the national rules say, with the legal texts.

Denmark requires operators of data centres with installed IT power of 500 kW or more to report to the EU database by 15 May each year (order 926 of 2024). Order 1167 of 2025, in force since 11 October 2025, requires data centres above 1 MW of nominal energy input to use surplus heat unless a cost-benefit analysis approved by the Danish Energy Agency shows this is not feasible. Order 892, published 15 October 2026 and in force since 19 October 2026, puts data centres in category 4, the last of four grid priority categories. Grid companies must refuse category 3 and 4 connection requests where capacity is limited and higher priorities would be displaced.
