Up to 7 countries at a time. A zero means no measure was found in this compilation, not that none exists.
None of the selected countries is covered by an EU-wide measure in this compilation.
Subsidies/support for new regional data centres and related power/network infrastructure.
Lowers the cost of building outside the Tokyo/Osaka corridor: government subsidies support new regional data centres (e.g. Hokkaido, Kyushu) and related power/network links.
Large DCs near Seoul face stricter/deferred grid-connection review; distributed-energy obligations for large users; incentives to locate in non-capital regions.
Typical effect of this kind of measure: Controls whether: and how fast: a data center can get grid power. Can delay, cap or block new capacity, and may force on-site generation or demand commitments.
New large DCs must meet PUE<=1.25 (national hubs) / <=1.3 elsewhere, plus increasing renewable-energy use (target ~80% green-power utilisation for hub DCs by the early 2030s).
Typical effect of this kind of measure: Sets efficiency rules a data center must meet, e.g. a PUE ceiling or mandatory KPI reporting. Can force cooling/design changes and rule out inefficient builds.
Directs DC siting to designated clusters; efficiency (PUE) and renewable conditions apply; siting/fiscal incentives available within hubs.
Typical effect of this kind of measure: Shapes demand and siting (data localization, cloud-first, digital plans). Indirect: it drives where capacity is needed rather than regulating the facility itself.
New capacity awarded to best-in-class efficient/green DCs; tropical-climate PUE target of <=1.3 and high energy efficiency standards.
New capacity is allocated competitively to the most efficient and greenest bids (tropical PUE target ≤1.3); a new site needs an allocation before it can be built.
Framework/metrics (incl. PUE) for green DC certification and energy-management systems.
Typical effect of this kind of measure: Sets efficiency rules a data center must meet, e.g. a PUE ceiling or mandatory KPI reporting. Can force cooling/design changes and rule out inefficient builds.
