Stoneweg Icona data centre fund rebranded to AiOnX; adds fifth asset in UK

[SINGAPORE] The trustee-manager of Stoneweg European Business Trust announced on Wednesday (Jul 2) that SWI Group, the sponsor of Stoneweg Europe Stapled Trust (Sert), has added a fifth data centre site in the UK, to its fund named AiOnX. 

The Cambridgeshire site will be located at Sutton-in-the-Isle, between Cambridge and Peterborough, and be scaled up to a final capacity of 330 megawatts. 

It will also target the UK’s cluster of global technology operators located in the “Golden Triangle” – between Cambridge, Oxford and London – to serve artificial intelligence and cloud demand in the area, and become one of the biggest data centres in the UK. 

The Stoneweg Icona data centre fund – rebranded as AiOnX – will now encompass five high-specification hyperscale data centre sites across strategic European locations including Spain, Italy, and now the UK.

The development plan of the five assets aims at creating 2 gigawatt total capacity for an investment of more than 20 billion euros (S$30 billion), for AiOnX to become one of Europe’s largest data centre owners.

This is one of the first moves by SWI Group – comprising Stoneweg, Icona Capital, its subsidiaries and associates – since it became Sert’s sponsor in end-2024.
