Sesterce Rovaltain Campus, Alixan (115 rue René Truhaut)
Announced
France · 1 project · Last reported
Summary
Sesterce's release of 6 October 2026 names its Rovaltain project in Alixan, says it is becoming a Sesterce Campus to be revised around six commitments, reaffirms a strict 40 MW limit for the supercomputer and states that implementation of the building permit already obtained is suspended while the commitments are integrated. The project is therefore announced as of 6 October 2026. The December 2025 permit is not in effect for implementation, so no permitted status, site work or construction is asserted. evidence

Rovaltain Sesterce Campus — proposed 40 MW AI supercomputer campus (permit PC 026 004 25 00020, implementation suspended)
Announced last observed as of · Project announcement
The national planning-authorisation register lists building permit PC 026 004 25 00020 (NUM_DAU 0260042500020), authorised on 18 December 2025, to SESTERCE GROUP (SIREN 902 372 481, NAF 64.20Z) for works on existing buildings at 115 rue René Truhaut, 26300 Alixan, on cadastral parcels YC 1039, YC 1040 and YC 1041 with a declared land area of 52,773 m2. The works transform 3,130 m2 and demolish 2,668 m2 of the 13,140 m2 of existing non-residential floor and create 5,320 m2 of warehouse-class floor; the state is 'autorisé' with no declared opening of works. evidence

- Precision scope
- Centroid of the three cadastral parcels named in Sesterce's permit PC 026 004 25 00020 (YC 1039, YC 1040 and YC 1041 in Alixan, 0.61 ha, about 112 by 111 m) at 115 rue René Truhaut. The permit declares 5.28 ha of land, so the point locates the listed part of the project land, not the whole site or any building.
- Horizontal uncertainty
Not reported
The cadastral service publishes no positional accuracy; the point is the centroid of the 0.61 ha listed part of a declared 5.28 ha permit land whose remaining parcels are not published, so the project buildings may lie a few hundred metres away within the Rovaltain park; the project is also to be revised.

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.
