Summary

Green's media release of 26 October 2026 states that Green has acquired from ABB the Areal Grossacher und Grändel in Birr, about 250,000 m2 of largely unused industrial land, and plans to develop it in stages into a campus with data-centre infrastructure, centred on an energy-efficient data-centre campus whose waste heat is to be offered as process heat and to a heat network, on the basis of the existing Ergänzungsplan, with further areas for industry, commerce and public green space to be defined with the municipality and the canton. The dated operator disclosure names the project and its site, so the project is announced. No building permit, construction start, capacity or timetable is stated, and no physical status is asserted. evidence

The cantonal government's decision of 22 January 2025 (dispatched 28 January 2025) approves, with direct amendments, the general revision of Birr's land-use planning adopted by the municipal assembly on 27 June 2024. Its main settlement themes include the central development areas 'Dorfkern/Dorfsmatt', 'Wyde', 'Bachtalen' and 'Grossacher und Grändel', for which the building and use regulations contain detailed provisions. It is listed in the OEREB extract as the legal provision of the Ergänzungsplan Grossacher & Grändel. It concerns zoning only and does not authorise a data centre. evidence

Derivation: coordinate_transform
Precision scope: Computed centroid of the five Birr cadastral parcels (1069, 381, 1311, 376, 383) that the Aargau OEREB cadastre places entirely within the Ergänzungsplan and Spezialzone Grossacher & Grändel; together 250,676 m2 by land-register area, matching Green's 'about 250,000 m2' Areal Grossacher und Grändel. It marks the purchased planning area as a whole, not a data-centre building, phase or construction extent; no building position is published.
Horizontal uncertainty: Not reported
The point is a parcel-union centroid of a 25 ha planning area whose parcels extend up to about 560 m from it; the position of any data-centre building within the area is not published, so the data centre may lie anywhere within that distance.
Geometry evidence: 4224d3b1

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.
