Summary

On 12 August 2026 the Environment Ministry determined that environmental condition no. 6 of VIA decree 255/2025 for Microsoft 4825 Italy S.r.l.'s 'Data Center MIL03, Settimo Milanese (MI)' project is complied with (MASE_2026-0173385, published on 27 August 2026). This dated government record names the project and supports announced only. The VIA decree of 13 May 2025 is an environmental compatibility judgement, not a planning or building permit; no building permit, construction start, completion or operation of MIL03 is established by the captured sources. evidence

Data Center MIL03 — proposed single-building data centre (MASE ID_VIP 10873)

Announced last observed as of 2026-08-12 · Project announcement

The opinion reviews the proponent's documentation on the planned well (well column materials, wellhead cabin, abstraction and reinjection wells) and radon measurements for the MIL03 data-centre project and finds condition 6 complied with. It contains no construction-progress statement. evidence

The VIA decree for Microsoft 4825 Italy S.r.l.'s Data Center MIL03 at Settimo Milanese records about 64 MWt of standby generator thermal input and a high-voltage supply over two 25 MW lines through an on-site HV/MV substation, and expresses a positive environmental compatibility judgement with conditions. An environmental assessment decree is not a planning or building permit. evidence

The non-technical summary places the future MIL03 data centre in the industrial zone of Settimo Milanese on the Cornaredo boundary, within the former Italtel (formerly Siemens) area, on currently uncultivated agricultural land of about 48,281 m2 beside existing data-centre buildings of other operators, set against via Reiss Romoli and via Edison. It describes a single two-storey building (server halls and administration), nine diesel standby generators on the west and east sides, an on-site HV substation in the south-east corner linked by two underground lines to Terna's Baggio station, and a 332 kWp rooftop PV system. The conditions of construction are set by a convention between the municipality and Microsoft signed on 3 April 2023. evidence

The portal record lists proponent MICROSOFT 4825 ITALY S.R.L., municipality Settimo Milanese, the VIA procedure concluded by decree DM_2025-0000255, and five compliance-verification procedures: condition 1 partially and condition 4 fully complied with on 3 April 2026, procedure 14188 complied with on 23 February 2026, the procedure for conditions 5 and 6 concluded with condition 6 complied with on 12 August 2026 (MASE_2026-0173385), and conditions 2, 3 and 9 partially complied with on 11 February 2026 and back under technical review since 21 May 2026. No construction or operating milestone is recorded. evidence

Microsoft's Italy community page links construction updates for its Bornasco and San Bovio datacenters and general articles on building and operating datacenters in Italy; it names no Settimo Milanese or MIL03 facility and gives no MIL03 status. evidence

Microsoft Corporation · publication date not stated

Georeferenced imagery extract used only to check the WGS84 reading of the filed generator-stack coordinates. Qualitative registration check only: the nine stack points fall on an undeveloped field immediately north-east of an existing data-centre compound, as the SIA describes; no systematic offset is apparent. This is not a measured accuracy and not a status observation. evidence

Location details

Coordinates: 45.47361, 9.04341
Geometry licence: all-rights-reserved
Use scope: Campus locator
Scope class: official_filing_generator_stack_mean
Authority: Compiled location reference
Source entity: Campus
Method: regulatory_filing_utm32_wgs84_generator_stack_coordinates_genset1_8_arithmetic_mean_inverse_projected_to_wgs84
Derivation: coordinate_transform
Precision scope: Mean of the eight server-hall generator stack coordinates (GENSET1-8) printed in UTM 32 WGS84 in the August 2024 air-dispersion study; the study places these generators outside the west and east sides of the single MIL03 building, so the mean falls between them, inside the planned building area of the 4.8 ha lot. All nine stacks lie within 56 m of the point. It locates the planned facility on its lot; it is not a surveyed footprint, parcel centroid or entrance.
Horizontal uncertainty: Not reported
The filing states no positional accuracy; the point is the mean of modelled generator positions from a 2024 design, whose stacks lie up to 56 m away, and the building outline itself is not printed in text. Decimal places are computation precision, not accuracy.
Geometry evidence: e4b96a65

A locator places the site on the map. It is not a building footprint, a construction extent or a surveyed boundary unless the use scope is an official boundary, and even then it is a parcel or permit boundary.
