Moody's: Exploring the EU's Data Centre Capacity Challenge
The EU faces a substantial infrastructure challenge as it attempts to compete with US and China data centre capacity. The bloc estimates it needs between €250bn (US$286bn) and €500bn (US$573bn) in capital investment across the next five to seven years to triple its data centre capacity alongside power grid improvements.
According to Moody's Ratings, the Nordics and Southern Europe will increasingly challenge FLAP-D markets. FLAP-D represents Frankfurt, London, Amsterdam, Paris and Dublin.
These five hubs have traditionally dominated European technology infrastructure, but secondary markets are now emerging as viable alternatives.
Power constraints drive geographic shift
According to the International Energy Agency (IEA), European data centre IT installed capacity reached 12GW in 2025, up from 11GW in 2024. In contrast, IT installed capacity in the US reached 39GW in 2025, up 26% from 31GW in 2024, while China hit 19GW.
The IEA's 2025 Energy for AI report states that wait times for securing a grid connection in the UK, Germany and the Netherlands can range from five to 10 years. In London, Europe's largest data centre market, power availability is constrained while grid connection queue times extend into the 2040s for some new projects.
Continued underinvestment could prolong the region's dependence on service providers outside the EU. Increased latency for European users could weaken the economic competitiveness of the region in AI and cloud services, which could result in the loss of high-value jobs to other markets.
The EU is aiming to decentralise data centre development to resolve this concentration and accelerate growth. Its AI continent action plan supports the creation of AI factories and gigafactories across Europe to distribute compute capacity away from congested hubs.
The proposed Cloud and AI Development Act seeks to establish a unified regulatory framework to strengthen local digital infrastructure and support regional development.
Nordic and Southern markets offer alternatives
Nordic markets are emerging as attractive regions for data centre developers as computing capacity and power constraints intensify in FLAP-D hubs.
Finland, Norway, Sweden and Denmark benefit from ambient cooling conditions for much of the year, reducing energy consumption and water dependency. This translates into lower operating costs and a favourable position under the planned environmental rating system of the EU.
The Nordics benefit from low baseline water stress, giving them an advantage over Southern European markets where water scarcity is a growing concern, particularly in Spain and Italy's northern industrial regions around Milan.
Southern European hubs offer regional connectivity and growing infrastructure investment. Italy faces power availability constraints, prompting transmission operator Terna to commit €23bn in investment targeted at increasing transport capacity.
Spain connects Southern Europe with Latin America and North Africa through major subsea cable landing points, where grid operator Red Eléctrica de España plans to invest €6bn. Portugal enjoys a position as a connectivity hub, where Microsoft announced a US$10bn investment in a new campus in Sines.
Regulatory and financial fragmentation persists
Regulation remains fragmented across the 27 member states, with environmental regulation stricter than in the US. The EU is planning to launch an environmental rating system next year based on KPIs that measure power and water consumption, which could carry credit implications for operators and lenders.
A key factor affecting development is the fragmented nature of European financing. Funding is dispersed across multiple regions among real estate lenders, infrastructure funds and banks – each operating with distinct investment mandates and risk appetites.
The US market benefits from deep project finance and private credit markets that support rapid financing at scale for new asset classes. Europe also lacks a large number of highly-rated domestic cloud or social media providers with AI investment plans and long-term compute commitments of 15 years or more.
Lenders are exploring ways to tap the early-stage securitisation market to obtain funding as funding requirements expand. While the shifting map toward the Nordics and Southern Europe shows the region is responding, structural barriers could threaten the EU's seven-year expansion goal.
