Summary

ARPA Lombardia's letter registered by the Ministry on 9 October 2026, in the compliance verification ID_VIP 15187 of condition 6B of VIA decree no. 411 of 30 June 2026, names the project 'Realizzazione di un nuovo Data Center denominato MIL05 ubicato nel comune di Vignate (MI)' of Infrastructure Italia Land 5 S.r.l. and finds the proponent's power-line excavation documents suitable. This dated government record supports announced only. The VIA decree is an environmental-compatibility decision, not a building permit; the conditions being verified are ante-operam measures due before works start, and a second compliance verification (ID_VIP 15251, conditions 3 and 6A) entered technical review on 16 October 2026. No building permit, site work, construction or operation is asserted. evidence

MIL05 — planned 60 MW IT two-building data-centre campus (MIL05A and MIL05B; VIA decree DM 411/2026, ID_VIP 13497)

Announced last observed as of 2026-10-09 · Project announcement

The project page names the proponent Infrastructure Italia Land 5 S.r.l., the territory (Lombardia, Milano, Vignate) and three procedures: the VIA ID_VIP 13497 filed 23 December 2024, concluded by decree DM_2026-0000411 of 30 June 2026 (positive with conditions, notified 9 July 2026); a compliance verification ID_VIP 15187 filed 7 August 2026 for condition 6B; and a compliance verification ID_VIP 15251 filed 30 September 2026 for conditions 3 and 6A, whose technical review by the CTVIA started on 16 October 2026. Both compliance verifications are in technical review. evidence

The decree, on the application of Infrastructure Italia Land 5 S.r.l. received 23 December 2024, records that the project provides in Vignate (MI) for a new data centre supplied by two 220 kV cables, with 50 emergency generators of 298 MWt in total, diesel storage of 2,083 m3, a dedicated 220 kV substation on the south-east side of the site and photovoltaic plants on the roofs and car-park canopies, and expresses a positive environmental-compatibility judgement with conditions. It is an environmental decision under the VIA procedure, not a building permit. evidence

The proponent's report, headed 'MIL05 Vignate (MI) - Data Center, Via Galileo Galilei SNC, 20052 Vignate (MI)', refers to the conditions of MASE decree 411/2026 for project ID_VIP 13497 and states that this first phase of compliance verification concerns measures to be put in place before the start of works; condition 3 (ante-operam, before the start of works) requires a construction-site traffic study, which is attached. The header and introduction also carry an 'ID_VIP 11245', a 'Decreto MASE 212.10-04-2026' and a 'VIA postuma' wording that match a different STACK procedure (Liscate) and appear to be template carry-overs; the body, the MASE page and the ARPA letter all cite decree 411/2026 for ID_VIP 13497. evidence

The air-quality study models 50 standby-generator stacks (E1-E50, 14 m high) and prints their coordinates in UTM 32N WGS84 in Tabella 4.3b: E1-E20 at about 528,817-529,013 E / 5,038,782-5,038,810 N, E21-E39 at about 528,838-529,031 E / 5,038,652-5,038,679 N, and E40-E50 at about 528,630-528,779 E / 5,038,550-5,038,577 N. evidence

Georeferenced imagery extract used only to check the WGS84 reading of the filed building outlines: A and B fall on a large cleared plot south of an existing factory complex, C and D on the south-west lot (wooded strip and a small existing building), with no systematic offset. Not a measured accuracy and not a status observation. evidence

Use scope: Campus locator
Scope class: official_filing_building_outline_union_centroid

Derivation: coordinate_transform
Precision scope: Area centroid of the union of the four planned building outlines (A, B, C and D, 18,086 m2 in total) printed in UTM 32N WGS84 in the proponent's building-downwash integration to the MIL05 VIA. A and B form the main MIL05A data-hall building; C and D lie on the south-west MIL05B lot, 50 m (D) and 116 m (C) from A+B. The point falls inside outline A, 10.7 m from its edge; the outer vertices are up to 297 m away. The outlines are modelling inputs, not surveyed footprints or parcel boundaries.
Horizontal uncertainty: Not reported
The filing states no positional accuracy; the point is the computed centroid of modelled outlines spread over about 430 by 230 m, and the final design may differ. Decimal places are computation precision, not accuracy.
Geometry evidence: a70b80b2

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.
