Microsoft says Denmark East is open; a Danish region is not a Swedish capacity update

On 26 March 2026 Microsoft announced the official opening of Denmark East, with campuses named in Høje Taastrup, Køge and Roskilde. The notice is a Nordic-neighbour region event. It does not restate Microsoft Gävle, Sandviken or Staffanstorp, and it does not publish a Swedish megawatt figure.

Microsoft’s 26 March 2026 Source EMEA notice says the company announced the official opening of its new Danish datacenter region, Denmark East. It names campuses in Høje Taastrup, Køge and Roskilde on Zealand. Those names are useful for a Nordic map of hyperscale regions. They are not Swedish municipalities and they do not move a pin in this register.

The notice lists customer-facing consequences: local data residency in Denmark under European legal protection, multiple independent datacenter zones inside the region, and access to Azure and Microsoft 365. It points to the EU Data Boundary and to Microsoft’s European Digital Commitments of 30 April 2025. Those are product and policy claims about the Danish region. They are not a Swedish operating update.

Sustainability wording in the same notice must keep its geography. Microsoft says it has entered into long-term power-purchase agreements in Denmark that together provide for a total capacity of 130 MW of renewable energy per year. That is a Danish PPA envelope, not a hall IT-load and not a Swedish connection. The notice also says the Danish datacenters were designed with zero water use for cooling, for LEED Gold certification, and to ultimately operate at a PUE of 1.16. Those are design or target sentences for Denmark.

Heat recovery is described as a Danish first, not a Swedish delivery. Microsoft says the Høje-Taastrup site will be its first operational at-scale waste-heat recovery in Denmark, with the ability to warm around 6,000 local homes, and that future expansion is planned in Køge. Køge’s mayor is quoted as expecting surplus heat to the local district-heating network over time. Treat those sentences as named Danish claims. Do not copy them onto Staffanstorp or Gävle.

The site-selection lesson for Sweden is comparative, not arithmetic. Denmark East shows a hyperscaler completing a multi-municipality Nordic region with an explicit residency and heat story. Sweden already has a historic Microsoft region opening from 16 November 2021 in this register. The 2026 Danish opening does not tell the reader whether a Swedish campus is expanding, pausing or unchanged. Each country file keeps its own source.

A later Swedish Microsoft source would need to name the Swedish event it claims: a campus milestone, a capacity definition, a grid paper or an operating result. Until such a source exists, Denmark East is context for how Microsoft talks about Nordic regions. It is not a spare-megawatt argument for SE4 or a reason to merge the Swedish Microsoft rows.

DataCenterSweden therefore stores the 26 March 2026 notice as an international region opening that matters for Nordic comparison. Swedish Microsoft project stages and metric rows stay where their own sources left them. The 130 MW PPA figure is not written into any Swedish capacity cell.

Why it matters

A neighbour region opening changes the Nordic comparison set. It does not refresh a Swedish campus row and it does not turn a Danish PPA envelope into Swedish IT load.

What remains unknown

The Denmark East notice does not state which Danish campuses were energised on 26 March 2026, does not publish Swedish megawatts, and does not update Gävle, Sandviken or Staffanstorp.
