Summary
- SP01 is planned for 70MW of IT capacity at full build-out, with the first 10MW phase due in summer 2027.
- The campus is being designed for AI, HPC, and cloud workloads, with direct-to-chip liquid cooling and rack densities of up to 250kW.
- Granada adds another Spanish capacity play to a market where power, phasing, and customer commitments will decide which announced projects become live load.
Alto Infrastructure has started construction on SP01, a planned 70MW IT-load AI and high-performance computing campus in Escúzar, Granada.
The project is being developed at CITAI, the industrial, technology, and innovation park in the municipality. Its first phase is scheduled to enter service in summer 2027 with 10MW of IT capacity, before rising to 25MW by the end of that year.
At full build-out, now scheduled for late 2029, SP01 is expected to reach 100MW of gross electrical power and 70MW of IT load. The total investment envelope has been put at more than €3bn, including physical infrastructure and the technology equipment expected to be deployed by customers.
Designed around dense compute
The specification points towards a campus built for GPU-era workloads rather than conventional enterprise IT. Alto says the site will use direct-to-chip liquid cooling and support rack densities of up to 250kW, putting mechanical and electrical design at the centre of the project from the start.
The first 10MW phase will test more than the building shell. It will prove the power path, cooling approach, commissioning sequence, contractor base, and local operational model. The planned climb to 25MW before the end of 2027 leaves little room for slippage if grid works, equipment procurement, and customer fit-out do not align.
Alto has also referred to renewable power and low water consumption. Those claims will be measured against energy contracts, metered performance, cooling plant, heat rejection, and operating profile once the site is closer to energisation. Spain’s growing data centre pipeline is being shaped by the same hard constraints as the rest of Europe: firm power, deliverable land, planning consent, and credible customers.
Spain’s map widens beyond Madrid
Granada gives Spain another regional data centre proposition beyond the established Madrid and Barcelona corridors. Developers are increasingly looking at locations where land, energy infrastructure, and public-sector support can be assembled without the congestion seen in mature hubs.
That shift does not make secondary markets simple. A campus built for high-density AI needs fibre diversity, specialist contractors, liquid-cooling capability, secure logistics, maintenance skills, and customers prepared to place dense compute away from the deepest interconnection ecosystems. Land availability alone will not carry the project.
The cooling design will also shape operating risk. Direct-to-chip liquid systems bring pipework, coolant distribution, leak detection, service access, water treatment, heat exchangers, and different maintenance procedures into the facility layer. As rack power rises, the separation between IT procurement and building services becomes thinner.
Spain has become a more active data centre market because it can offer renewable resources, large sites, and growing cloud demand. The difficult part is turning announced megawatts into energised capacity. SP01 now moves from promotion into construction, where power delivery, phasing, and customer commitments will carry more weight than the headline investment figure.
