en.Wedoany.com Reported - Sydney-based AI cloud operator IREN has completed its acquisition of Spain's Nostrum Group, securing its first foothold in Europe with approximately 490 megawatts of secured grid-connected power. The financial terms of the transaction were not disclosed. The acquisition brings IREN a local data center development team and project pipeline, targeting enterprises currently competing for scarce AI infrastructure capacity in Europe.
For infrastructure buyers, the core figure in the acquisition is not the price, but the 490 MW of power. In a market where GPU orders outpace substation approvals, secured power has become the hard currency of AI infrastructure. Founded in Australia, IREN plans to establish an operational base in Europe through this acquisition. Nostrum (formally known as Ingenostrum, S.L.) brings Spanish grid-connected AI data center development assets, along with over 50 employees spanning development, engineering, construction, and operations.
The significance of this deal extends beyond territorial expansion; it equips IREN with local execution capability in a market dependent on permits, grid access, fiber routing, renewable energy availability, and political tolerance. According to the company, Spain offers a European platform with renewable energy availability and fiber connectivity. In data center planning, power and connectivity have become strategic inputs rather than logistical afterthoughts, making Spain increasingly attractive.
The acquisition also brings IREN into Europe's regulatory and energy political environment. AI data centers consume enormous amounts of power, and the European market has low tolerance for issues such as grid strain, water usage, land planning, and emission claims. While a secured power pipeline helps, it cannot eliminate community scrutiny or interconnection delays. Nostrum will operate under the IREN brand, suggesting integration rather than a loose regional affiliate, but this also carries execution risks. Local development teams often have insights unknown to central management, such as which municipalities are slow-moving, which grid milestones are fragile, and which construction assumptions are overly optimistic.
For hosting and cloud providers, the signal is clear: AI infrastructure is consolidating around power access and chip access. Providers that can secure sites, energy, and fiber will likely determine the capacity availability for enterprise AI workloads in Europe. IREN gains a European beachhead, while Nostrum gains capital and scale. This deal underscores that AI infrastructure expansion is becoming a power development business with a cloud brand label.
