Summary

Microsoft Dublin Data Center Campus — existing operations of DB3, DB4 and DB5 (EPA IE licence P1190-01)

Microsoft Ireland Operations Limited's 2026 annual noise survey under IE licence P1190-01 (AWN Consulting report 267501.0593NR02, issued 31 August 2026 and posted to LEAP on 1 October 2026) states that Microsoft operates a facility at Unit 74, Grange Castle Business Park under licence P1190-01 and that 'The facility operates 24 hours a day, 7 days a week'. The licensee's 2025 AER identifies the P1190-01 installation as DB3-DB5. This supports current operation of that licensed installation on 31 August 2026. The AER also mentions construction and decommissioning activity across the campus and recommissioning work in legacy rooms in 2025; it does not say that any of DB3, DB4 or DB5 has stopped operating, and no building-level status beyond the installation's operation is asserted. No IT capacity is stated; the 41 diesel generators are back-up plant. evidence

Microsoft Dublin Data Center Campus — existing operations of DUB6, DUB7, DUB8, DUB9, DUB10, DUB12 and DUB13 (EPA IE licence P1191-01)

Microsoft Ireland Operations Limited's 2026 annual noise survey under IE licence P1191-01 (AWN Consulting report 267501.0593NR03, issued 31 August 2026 and filed with the EPA, posted to LEAP on 1 October 2026) states that Microsoft 'operates a facility at Unit 74, Grange Castle Business Park' under licence P1191-01 and that 'The facility operates 24 hours a day, 7 days a week'. Microsoft's letter to the EPA of 22 September 2026 identifies the P1191-01 installation as Dub 6, 7, 8, 9, 10, 12 and 13, with eight generator yards. This supports current operation of that licensed data storage installation on 31 August 2026. The other Microsoft installations on the campus (P1187-01 and P1190-01) and DUB14/DUB15 are not part of this project, and no IT capacity is stated. evidence

Microsoft Dublin Data Center Campus — operating DUB14 and DUB15 installation with the Central Administration Building (EPA IE licence P1187-01; DUB15 build-out not asserted complete)

Microsoft Ireland Operations Limited's 2026 annual noise survey under IE licence P1187-01 (AWN Consulting report 267501.0593NR01, issued 31 August 2026 and posted to the EPA's LEAP site on 1 October 2026) states that Microsoft operates a facility at Unit 74, Grange Castle Business Park under licence P1187-01 and that 'The facility operates 24 hours a day, 7 days a week'. The licensee's 2025 AER identifies the P1187-01 installation as DUB14, DUB15 and the CAB administration building. This supports current operation of the licensed installation on 31 August 2026. The same AER reports DUB14 fully loaded in 2025 and DUB15 in phased deployment and commissioning with the remainder of its site under construction, so completion of DUB15 or of all its halls is not asserted, and the survey's July measurement days are not used as the observation. No IT capacity is stated; the 22 gas engines and 21 diesel generators are standby plant. evidence

Microsoft Dublin Data Center Campus — existing operations of DB3, DB4 and DB5 (EPA IE licence P1190-01)

Operational last observed as of 2026-08-31 · Authoritative status update

The licensee's AER for 2025 describes the facility as a data storage installation in Grange Castle South Business Park licensed under P1190-01 for back-up generators, and states that the licence covers DB3-DB5. It reports that the back-up generators run on HVO, attended noise monitoring in Q4 2025, stormwater from DB3, DB4 and DB5, and higher 2025 water use attributed to construction and decommissioning activity across the campus and to maintenance and recommissioning of older equipment and legacy rooms; it does not say that DB3, DB4 or DB5 has ceased operation. evidence

Precision scope: Site-centre point of the EPA-licensed P1191-01 installation (Dub 6, 7, 8, 9, 10, 12 and 13), the larger eastern part of Microsoft's Grange Castle campus, from the register's National Grid Reference N231310 E303630, transformed from Irish Grid (TM75) to WGS84. It is used as the campus locator; it does not locate any one building, a footprint, an entrance or the installation boundary, and the campus's P1187-01 and P1190-01 installation points lie 430 m and 692 m away.
Horizontal uncertainty: Not reported
The register gives a single site-centre grid reference at 1 m resolution with no stated survey accuracy for a multi-building installation; the offset to any building is unknown and the wider campus extends about 700 m to the west and north-west. The TM75-to-WGS84 operation is rated at 1 m; the alternative operation moves the point 2.1 m. Decimal places are arithmetic precision.
Geometry evidence: 2f2280bb

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.
