Summary
- Lombardy has adopted a regional framework for data centre development as Italy prepares for a major capacity buildout.
- The region wants to promote brownfield sites while discouraging farmland and sensitive land through higher construction charges.
- The law reflects a wider European shift from permissive growth to managed data centre planning, power, water, and environmental scrutiny.
Regione Lombardia has approved a regional framework for data centre development, putting Italy’s largest data centre market on a more formal planning footing as demand accelerates around Milan.
The framework is intended to manage demand for new facilities in a region expected to capture a large share of Italy’s next capacity wave. Regional officials have linked the approach to a national buildout that could reach several gigawatts, with Lombardy expected to host much of the new development because of Milan’s established connectivity and enterprise base.
The regional approach favours brownfield sites and places heavier financial pressure on schemes seeking agricultural land or sensitive areas. Lombardy’s existing data centre authorisation guidance directs municipalities to consider environmental procedures, emergency generation, soil sealing, landscape, biodiversity, water, and health impacts.
Milan is Italy’s dominant data centre hub, accounting for most of the country’s installed data centre power capacity. The regional law therefore lands in the most commercially important part of the Italian market, where international operators are seeking powered land, cloud demand is rising, and public authorities are trying to avoid unmanaged land take.
Italy’s data centre market is being formalised
Italy has moved quickly from an underdeveloped data centre market to one of Europe’s more closely watched expansion zones. Milan offers enterprise density, cloud demand, connectivity, and proximity to northern European markets. Puglia is also being positioned as a southern digital hub, helped by submarine cable routes around Bari and the wider Mediterranean corridor.
That growth is now colliding with familiar European constraints. Large data centres require grid capacity, backup generation, substations, water and wastewater strategies, resilient connectivity, road access, and long-term operational permissions. As AI workloads increase power density, the infrastructure footprint becomes harder to separate from regional energy and land-use planning.
Lombardy’s push towards disused industrial land follows a broader European policy direction. Brownfield development offers a way to reuse already-disturbed land, reduce the political cost of new build, and potentially make use of existing utility corridors. It can also bring complications through contamination, demolition, remediation, legacy industrial permits, and complex ownership structures.
Higher charges for farmland and sensitive sites send a clear signal, although they may not deter every large project. Data centre developments worth hundreds of millions or billions of euros may absorb additional land charges if power, fibre, and customer demand make a site attractive enough. The stronger test will be whether municipalities and regional authorities can create a fast, credible route for brownfield schemes while still applying environmental safeguards.
Policy certainty can become a competitive tool
Italy’s authorisation pathways have not always offered the consistency sought by international operators. A clearer regional regime can reduce early-stage uncertainty around acceptable locations, environmental procedures, heat rejection, backup generation, and grid interface requirements. Less uncertainty also makes it easier to price schemes, place equipment orders, and secure customer commitments.
The framework also puts sustainability claims under more practical pressure. If a region steers data centres towards brownfield land, scrutinises water and environmental impacts, and connects approvals to local planning rules, developers will need to present more than renewable-energy certificates and generic efficiency language. Heat reuse, water sourcing, grid flexibility, biodiversity, and emergency generation will sit closer to the centre of the consenting argument.
Lombardy’s challenge is to balance speed and control. Restricting development too heavily would risk pushing investment elsewhere, while unmanaged growth would invite local opposition, grid friction, and land-use conflict. The new law is an attempt to make data centre expansion governable before the largest wave of Italian AI and cloud capacity reaches local planning desks.
