Krolmap announced in March 2026 plans to build a 225-megawatt off-grid data center in Zaragoza, Spain, designed specifically to support large-scale artificial intelligence (AI) workloads. The facility aims to provide a reliable and scalable power supply independent of the traditional electrical grid, addressing critical challenges faced by AI-focused data centers.
The Zaragoza data center will operate without relying on the local power grid, instead using dedicated energy sources to maintain uninterrupted operations. According to Data Center Dynamics, this off-grid configuration is intended to reduce dependency on external grid fluctuations and enhance energy reliability, a vital factor for AI workloads requiring consistent, high-performance computing resources Data Center Dynamics.
With a capacity of 225MW, the project ranks among the largest data centers planned in Europe. It targets the increasing electrical demands of AI training and inference tasks, which have pushed existing data center infrastructure to their limits. Krolmap’s approach reflects a strategic response to the rapid growth in AI-related power consumption.
While Krolmap has not disclosed full details about the energy sources and infrastructure that will support the off-grid status, the company has indicated intentions to incorporate renewable energy and possibly on-site generation technologies. This approach aligns with industry trends emphasizing sustainability and efforts to reduce the carbon footprint of data center operations.
Industry analysts note that the shift toward off-grid data centers addresses the challenges of expanding capacity in urban areas, where upgrading the electrical grid is often costly and time-consuming. By operating independently, data centers can scale power availability more flexibly and avoid constraints linked to grid capacity and stability.
The Zaragoza project also underscores Spain’s expanding role as a technology infrastructure hub in Europe. Its geographic location offers logistical advantages and access to renewable energy resources, supporting Krolmap’s goal of balancing high-capacity computing needs with environmental considerations.
The increasing power consumption associated with AI workloads has prompted data center operators worldwide to explore innovative infrastructure solutions. Krolmap’s off-grid model could serve as a blueprint for future AI-focused data centers, especially in regions where grid limitations impede expansion.
Moreover, operating off-grid may reduce risks related to grid outages or instabilities that can disrupt critical AI services. Ensuring continuous power is essential for AI training and inference tasks that require high availability.
Construction on the Zaragoza facility is expected to begin within the next year, with completion targeted for the late 2020s. Krolmap plans to release further technical and operational details as the project advances Data Center Dynamics.
The data center sector has seen growing investments in infrastructure tailored to AI workloads. Companies are expanding their portfolios to accommodate specialized computing demands while emphasizing energy independence and scalability. Krolmap’s Zaragoza project contributes to this trend by proposing an innovative off-grid infrastructure model.
In summary, Krolmap’s 225MW off-grid data center in Zaragoza represents a significant development in Europe’s AI infrastructure landscape. By reducing reliance on the traditional electrical grid, the facility aims to provide reliable, scalable, and potentially greener power to meet the escalating computing demands of AI applications.
