Project and phase identity

Kolabacken is a distinct physical campus, not another name for Espoo or Vihti. The municipal notice separates HEL04 from HEL05–06.

What changed in the record

The March 2025 municipal notice records the phase-two application. Microsoft’s April 2026 regional release later reports all three campuses’ second-phase permits. This review attributes the later permit assertion to Microsoft; it does not certify the underlying conditions.

Investor read-through

Our analysis: completed earthworks and progressing interiors support a construction classification; neither establishes commissioning or recurring cloud-service output.

Delivery commitments and dated checkpoints

Target: Microsoft’s regional first-phase building-work target is around year-end 2026–2027; service launch to be announced separately.

• 2025-03-14: The municipality distinguishes permitted HEL04 from the then-pending HEL05–06 application LP-257-2024-02386, filed February 14, 2025. Original municipal permit notice
• Undated current source: The April 2026 update reports first-building facade/interior work and second-building foundations at Kirkkonummi; completion of Destia earthworks is not data-centre completion. Original company construction update
• 2026-04-28: Microsoft identifies three separate campuses and phased delivery; first-phase building work targets the turn of 2026–2027, followed by commissioning preparation. Second-phase permits are issuer-reported. Original company disclosure
• 2026-06-09: DCD separately identifies Espoo, Kirkkonummi and Vihti as developments, while attributing site-progress details to Microsoft. Its Vaasa land acquisition is another project. Independent specialist reporting; construction details attributed to Microsoft
• Undated current source: Fortum identifies planned heat recovery from Espoo and Kirkkonummi. The roughly 40% district-heat contribution is a combined future network estimate, not IT capacity or present delivery. Original heat-offtake partner disclosure

Unavailable: no matched, comparable accepted operating-IT target and actual.

Company connections

Microsoft develops the distinct Kolabacken campus. Fortum’s associated heat-recovery infrastructure is separate from Microsoft’s computing operations.

What remains unverified

Energization, commissioning, accepted customer capacity, current operating IT MW, utilisation, project spending and campus earnings remain unverified. Direct final phase-two permit conditions and current compliance disposition require retrieval.

Sources and claim boundaries

Documents are counted as documents, not independent confirmations. Same-issuer releases and their rewrites share an underlying claim. Five documents; municipal notice establishes the historical application, not the present final legal disposition. Microsoft site/region updates share an issuer; DCD quotes those updates. Fortum corroborates the heat relationship, not compute commissioning.
