Summary
- The proposed ten-module campus would provide 120MW of computing capacity across two phases by the end of 2030.
- Plans include a dedicated substation and 350 solar panels, but the announcement does not identify financing, customers, an operator, or a site-specific grid agreement.
- Strategic-project recognition, planning, grid access, funding, and enabling works remain the main tests of deliverability.
The Government of Asturias has presented plans for a €1.226 billion data centre campus in Salas, with the promoter targeting 120MW of computing capacity by the end of 2030.
Digital Valley Asturias is being promoted by Sales For You Consulting, or S4U. The proposal comprises ten data centre modules on a 154,584 sq m site, of which 46,865 sq m would be occupied by equipment and supporting infrastructure.
The masterplan also includes a dedicated electrical substation, 350 photovoltaic panels, 375 parking spaces, and a commitment to reserve 28 per cent of the site for green areas. The project is intended to support data processing, storage, cloud services, and artificial intelligence workloads.
It remains at the proposal and administrative-processing stage. S4U is seeking recognition under Asturias’s Projects of Strategic Regional Interest framework, known as PIER, while the regional government expects administrative work to continue through 2026 and 2027.
Two phases separate the plan from full build-out
The investment programme is divided into two main phases. The first would allocate €240 million to 24MW of computing capacity, while the second would add 96MW for a stated €960 million. Land, urbanisation, and photovoltaic work take the announced total to €1.2263 billion.
Urbanisation is scheduled between the second half of 2027 and the first half of 2028. Construction of the data centre infrastructure is expected to run from the third quarter of 2027 until the fourth quarter of 2030, with the campus entering service progressively rather than through a single commissioning event.
The published figures establish an intended scale and timetable, but not a complete delivery structure. The announcement does not identify a lender, infrastructure investor, construction contractor, data centre operator, or anchor customer. It also does not confirm that a site-specific grid connection or energisation date has been agreed.
Those omissions are material because the stated 120MW relates to computing capacity rather than the campus’s total electrical requirement. Cooling, power conversion, lighting, security, and other supporting systems would increase the site’s demand above the IT load.
The inclusion of a substation shows that electrical infrastructure forms part of the masterplan. However, no connection voltage, contracted import capacity, network reinforcement programme, redundancy arrangement, or commissioning date has been disclosed.
The proposed photovoltaic installation also needs to be viewed in proportion to the campus. The government announcement gives the number of panels, but not their rated output or expected annual generation. For a development targeting 120MW of computing capacity, grid access and long-term electricity procurement would carry much more weight than a relatively small on-site array.
Economic forecasts remain promoter-side estimates
The Asturias government is presenting Digital Valley Asturias as an economic-diversification project for a region with an established industrial and energy base. Forecasts supplied at the launch put average employment at 120 direct jobs, 962 indirect jobs, and 236 induced jobs, with construction employment expected to peak at 3,000.
Those figures are economic projections rather than contracted positions. A PwC assessment cited by the regional government estimates that the project could contribute €4.177 billion to regional gross domestic product over 20 years and generate €753 million in cumulative fiscal benefit.
The published announcement does not include the assumptions used to calculate those effects, making it difficult to assess how much depends on construction expenditure, local sourcing, occupancy, energy costs, or the eventual operating model.
PIER recognition could help coordinate the administrative process, but it would not replace environmental assessment, planning permission, land agreements, utility approvals, financing, procurement, or customer commitments. Each of those elements will influence whether the promoter’s construction timetable remains achievable.
Phased delivery could allow the initial 24MW block to enter service before the complete campus is finished. That would still require the promoter to align power, planning, financing, equipment orders, construction, and customer demand around a defined first commissioning date, which has not yet been published.
The next useful evidence will therefore be procedural and commercial. Confirmation of PIER status, a planning application, grid terms, financing partners, an operator, customer commitments, and the start of enabling works would each move Digital Valley Asturias closer to deliverable capacity.
Asturias has put a location, proposed investment, phased capacity, and target completion date into the public domain. Until the missing power, funding, and operating arrangements are disclosed, the scheme remains a large development proposal rather than committed 120MW supply.
