Severe space constraints in major European tech hubs are pushing investors and developers to pursue rural data center sites across the continent.

Europe is experiencing its largest wave of digital infrastructure investment in history, driven almost entirely by surging demand for artificial intelligence and cloud computing. Cumulative investment in European data centers is projected to exceed €170 billion, with annual spending on construction and equipment now running above €25 billion.

Traditional hubs known as FLAP-D (Frankfurt, London, Amsterdam, Paris, Dublin) are confronting severe power grid saturation and stringent zoning restrictions. This bottleneck is redirecting capital toward new geographic frontiers. Southern Europe—specifically Madrid, Milan, Marseille, and Athens—is attracting developers seeking faster permitting processes, available grid capacity, and strategic undersea cable connectivity. Scandinavia (Norway, Sweden, and Finland) presents another viable alternative, offering abundant hydroelectric and wind power alongside natural climate-based cooling. Meanwhile, eastern and southeastern Europe (Poland, Romania, Bulgaria) is gaining traction due to lower land and construction costs, positioning these nations as emerging AI hubs.

According to a Reuters report, European AI data center developers are increasingly targeting less conventional locations away from metropolitan cores, leveraging cheaper energy and land alongside faster interconnection times. Commercial real estate firm JLL recently published data on planned hyperscale facilities expected to come online rapidly over the next two years. Because these facilities do not require close proximity to end users, they will be situated more than three times farther from major cities than those constructed over the previous three years. Between 2026 and 2028, the average distance of new sites from a major hub will reach 175 kilometers, compared to just 46 kilometers for projects delivered between 2022 and 2025, as urban power and land in cities like London and Frankfurt grow increasingly scarce.

JLL data indicates that projects in undeveloped areas now represent 39% of the pipeline, up from just 8% of completed projects. Conversely, the share of developments in city-center locations is projected to fall to 5%, down from 13%, with the remainder relocating to industrial parks or suburban zones. This geographic redistribution is largely propelled by AI training facilities, which consume massive quantities of electricity and require substantial water supplies for cooling systems.

“The deciding factor is increasingly where sufficient power can be secured, not simply where demand exists,” Asad Nuri, JLL’s head of data centers for Europe, the Middle East and Africa, told Reuters. “Data centers are moving to where the power is, not the other way around.” Reflecting this capital intensity, JLL estimates that the world’s four largest cloud service providers will spend $725 billion in 2026—a 77% increase from the $410 billion deployed in 2025—with the majority directed toward AI infrastructure and data centers. By 2030, AI workloads could account for approximately half of global data center capacity.

Tracking early-stage developments, DC Byte reports that of nine proposed European data centers exceeding one gigawatt in capacity, only one is slated near a major city (Paris). The remaining facilities are distributed across rural Spain, northern Sweden, and other non-metropolitan zones. While the FLAP-D core markets remain the largest and continue to attract demand, they are simultaneously grappling with acute land shortages, zoning constraints, and prolonged grid connection wait times. “Europe’s core markets will remain critical because business demand isn’t going to decline,” Martin Jensen, president of JLL’s EMEA data centers division, told Reuters. “AI infrastructure requires an entirely different scale of power and land,” he added.

JLL’s cost analysis underscores the financial disparity driving this migration. The average price for grid-connected land stands at €2.36 million per megawatt of IT load in core markets. In secondary cities such as Copenhagen, Warsaw, and Milan, the figure drops to €978,000, while tertiary locations like Bordeaux see averages of €512,000, with costs occasionally falling to €200,000. Amsterdam remains the most expensive market at approximately €2.7 million per megawatt, followed closely by London at €2.6 million and Frankfurt at €2.5 million.

Beyond geography and economics, developers must navigate stringent European regulations and evolving EU policies on digital sovereignty. The bloc enforces rigorous sustainability mandates, requiring new facilities to operate on nearly 100% renewable energy. Mandatory heat recovery systems for warming nearby municipalities or agricultural greenhouses are also becoming standard. While this regulatory framework may channel investment into economically disadvantaged regions—supporting local employment and growth—it also carries the risk of community pushback over resource depletion and competition for energy and water supplies. Concurrently, European governments and the EU are accelerating the deployment of domestic “AI Factories” to ensure citizen and corporate data remains stored and processed within European borders.

Greece is positioned at the epicenter of this regional expansion, rapidly developing into a digital hub for southeastern Europe, the Middle East, and North Africa. Its strategic geography, compounded by the recent arrival of new undersea fiber-optic cables, establishes it as a natural data gateway into Europe. Major international players are already committing significant capital. Microsoft is executing its nearly €1 billion “GR for Growth” initiative to construct a cluster of three large data centers in eastern Attica (Spata and Koropi). Digital Realty maintains a dominant position in the domestic market, continuing to expand its portfolio—including Athens 3 and 4 in Koropi—and investing hundreds of millions of euros, including a new facility in Heraklion, Crete. France’s Data4 is advancing a data center project in Attica, while Italy’s Sparkle has maintained operational presence in the country for years.

Additional momentum includes Google’s announcement to develop a cloud region in Greece. The Public Power Corporation (DEI) has entered the sector aggressively through a joint venture with UAE-based DAMAC, constructing a data center in Spata and planning a massive facility in western Macedonia. Lancom is expanding its Balkan Gate campus in Thessaloniki and developing a new center in Heraklion, Crete, a critical interconnection node, while international operators such as Apto Data Center are progressing with investments worth hundreds of millions in Attica. On the public infrastructure front, as part of the European EuroHPC network, Greece is commissioning its new national supercomputer, “Daedalus,” at the Lavrio Technological Cultural Park. This facility forms the core of Greece’s Pharos AI Factory and is specifically engineered for training large-scale AI models.

Separately, Greece has rejected Ankara’s recent claims as unfounded, reiterating that its sole bilateral dispute with Turkey pertains exclusively to the delimitation of maritime zones.
