Krolmap has announced plans for a technology campus of up to 150 MW in Aragón, positioning the project among the largest data center facilities proposed in the autonomous community so far. The infrastructure will be designed for high-density workloads, especially those related to artificial intelligence, cloud computing, and high-performance services.
However, the proposal is still surrounded by significant uncertainties. The company has not publicly specified the chosen site, budget, land area, construction schedule, or grid access agreements. It has not clarified whether the 150 MW refers to the total power of the complex or to computing load—a crucial distinction when comparing data center projects. For now, this should be considered a development in planning rather than an operational facility with confirmed construction plans.
A Large-Scale Project Still in the Planning Stage
A capacity of 150 MW places the future campus in a category far from conventional data centers. Facilities of this size are usually built in phases, with multiple independent buildings and a gradual deployment of technical rooms, electrical systems, cooling infrastructure, and IT equipment.
This approach allows growth to be aligned with actual demand. Developers can prepare the site and install general infrastructure, then activate capacity gradually as they contract operators, cloud platforms, or companies needing large compute clusters.
The figure announced by Krolmap does not mean that the full 150 MW will be available from day one. The published information indicates a planned capacity for development, but details on how it will be phased and what portion will be dedicated to servers are still missing.
Krolmap presents itself as a Spanish civil and industrial engineering firm specializing, among other areas, in data centers, energy, telecommunications, climate control, and project management. These activities are aligned with the needs of a campus that must integrate civil works, electrical lines, substations, fiber optics, backup systems, and cooling solutions.
The announcement also highlights one of the main challenges facing the sector: obtaining sufficient electrical power and ensuring its availability within a construction-compatible timeframe. The land parcel, building design, and fiber availability are important, but a project of this scale cannot proceed without a clear energy solution.
Additional considerations include obtaining permits, environmental assessments, water and cooling studies, access construction, and telecommunications connections. These processes can take years, so the announced capacity represents an aspirational goal rather than an immediate guarantee of implementation.
Aragón at the Center of New Digital Infrastructure Projects
The choice of Aragón is no coincidence. The region offers available land for large-scale developments, renewable energy production, high-capacity electrical connections, and a strategic location that facilitates connectivity with Madrid, Barcelona, and other major digital corridors on the peninsula.
The presence of large tech platforms has further enhanced its appeal. AWS operates a cloud region in Aragón and is planning expansion projects in Villanueva de Gállego, Huesca, El Burgo de Ebro, and Zaragoza, along with infrastructure in La Sotonera. The plans include fiber optic networks and high-voltage electrical supplies, aimed at services involving storage, data analysis, AI, and machine learning.
Microsoft is also developing its own region within the community. According to Aragón’s government documentation, there are three campuses in La Muela, Villamayor de Gállego, and Zaragoza, interconnected via a shared fiber network. The project involves data center buildings, substations, high-voltage lines, water infrastructure, and other external facilities necessary for operation.
Alongside these technology giants, real estate, energy, and digital infrastructure developers are emerging. This is creating an ecosystem that goes beyond server deployment to include construction, engineering, electrical systems, maintenance, security, telecommunications, and professional services.
The gathering of multiple projects also introduces competition. Developers need to reserve land, electrical capacity, and qualified vendors, while authorities must assess the cumulative impact on the energy transmission network, local territory, and resources.
The Aragón government considers this industry to have a growing impact on the regional economy. Mar Paños, Director General of Industrial Promotion and Innovation, stated in February 2026 that investments related to data centers could account for nearly 17% of Aragón’s Gross Domestic Product (GDP) during 2028, the peak year of construction activity, according to a report by Fundación Basilio Paraíso. This is an estimate of investment volume, not a projection of the industry’s permanent contribution to GDP.
Artificial Intelligence Raises Technical Demands
Krolmap’s campus is designed for high-density workloads, a characteristic increasingly associated with AI applications. Training and running large models require servers with numerous GPUs or accelerators, high-speed internal networks, and systems capable of delivering much higher power per rack than traditional enterprise setups.
This concentration of hardware also generates more heat. Therefore, new campuses must explore advanced cooling technologies suited for high densities, from more efficient air systems to direct liquid chip cooling solutions. The choice will depend on client requirements, installed hardware, and environmental conditions.
The challenge isn’t just about building electrical capacity buildings. The campus must ensure service continuity, redundancy, physical security, connectivity with multiple operators, and options for expansion without disrupting existing loads.
If Krolmap manages to secure the site, energy access, and administrative approvals, its project will add another 150 MW potential to a region already attracting significant investments in digital infrastructure. Until those details are finalized, the announcement reflects ambition but does not yet specify when construction will start or what capacity will actually be operational.
