Summary
- A partial start notice was issued on 29 October for foundation works.
- Phase one includes conversion of two former Northvolt buildings and construction of a new facility.
- Further construction approval and confirmation of contracted grid capacity remain outstanding.
EdgeConneX has received permission to begin foundation works at its proposed data centre development in Skellefteå, Sweden, following the issue of a partial construction start notice by the municipality.
The notice, issued on 29 October and reported by Swedish newspaper Norran on 9 November, allows a limited part of the development to proceed on the former Northvolt industrial site.
Permission covers foundation works for the project’s first construction phase. It does not constitute approval to begin all remaining construction activities or confirm that the complete development has satisfied its outstanding technical requirements.
The first phase involves adapting two existing buildings, previously designated DS4 and FA03, into a data hall known as DC01. A new building, DC02, is also planned alongside the converted facilities.
Skellefteå Municipality granted the building permit for this phase on 24 September. The subsequent start notice represents a separate procedural step required before the authorised construction work can begin.
According to the reporting, the partial notice was issued because the foundation design had reached the level of technical completion necessary for that work to proceed.
Other elements of the development have not yet reached the same stage of approval. A further technical consultation is expected after additional design work has been completed.
Municipal officials indicated that approximately 60% of the remaining technical design had been completed at the time of the latest consultation, although the available information does not establish when another start notice will be issued.
Former industrial facilities require adaptation
The first phase combines reuse of existing manufacturing infrastructure with construction of a purpose-built data centre building.
Converting industrial premises into computing facilities requires engineers to assess whether the existing structures can support the necessary electrical distribution, equipment loads, cooling systems, fire protection, and operational security arrangements.
Manufacturing buildings may offer suitable floor area and utility connections, but their original specifications do not necessarily correspond to the requirements of a modern data hall.
Electrical switchgear, backup power equipment, cooling plant, and network infrastructure may require substantial modification, depending on the condition and layout of the inherited facilities.
The new DC02 building provides an opportunity to incorporate those systems into a purpose-designed structure. Even so, its foundations must be engineered for the loads imposed by the building, supporting plant, and later installations.
Beginning foundation work is therefore a meaningful construction milestone, but it precedes much of the infrastructure installation and commissioning programme.
The development also forms part of the wider transition of industrial assets previously associated with Northvolt’s manufacturing operations in northern Sweden.
That context creates potential opportunities to reuse land, buildings, and existing utility infrastructure, while introducing questions about the allocation of electricity capacity previously associated with manufacturing.
Skellefteå Kraft has previously described arrangements involving EdgeConneX and battery manufacturer Lyten in relation to the former Northvolt site’s electrical connections.
However, the contracted network capacity allocated specifically to the EdgeConneX data centre has not been established in the reporting reviewed.
A previous industrial connection does not automatically confirm that the new operator has secured sufficient power for every planned phase or that the full electrical allocation is immediately available.
Nor can the number of proposed buildings reliably establish the facility’s ultimate IT load.
Earlier development information indicated an ambition to complete the initial phase around 2028, with further expansion potentially continuing into the following years.
Those longer-term plans remain distinct from the limited construction activity authorised by the latest notice.
Environmental consultation and subsequent technical approvals will continue alongside the development programme.
The next construction milestone will be the issue of further start notices allowing work beyond the approved foundations. Confirmation of electrical supply arrangements will also be necessary before the proposed campus can be assessed as deliverable computing capacity.
