How Data Centers Are Transforming Greece’s Real Estate Market

Greece is currently experiencing unprecedented momentum as major global players from the US, Europe, and the Middle East turn their investment focus toward the country. The nation’s strategic geographic position, its underwater optical cables connecting three continents, combined with the growing demand for digital infrastructure and artificial intelligence development, have positioned Greece as one of the most attractive emerging markets for data center growth. The trend began in fall 2020 when Microsoft announced plans to build three data centers in Attica—a project that proceeded more slowly than expected. Around the same time, American company Digital Realty acquired Lamda Hellix, Greece’s largest data center service provider, marking a significant entry into the domestic sector. Since then, the market has surged with continuous announcements of new investment projects by both international and Greek companies. One of the most impressive recent developments comes from DEH (Public Power Corporation), which unveiled plans for a mega data center campus in Western Macedonia. This strategically important project aligns with Greece’s transition to renewable energy sources and leverages regional infrastructure seeking new developmental identity post-decarbonization. In Attica, Digital Realty continues to lead with three operational data centers while constructing two more. Meanwhile, French firm Data4 is developing its first Greek data center in Megara, aiming to launch operations early 2026. Additionally, DEH collaborates with DAMAC (United Arab Emirates) on building a 12.5 MW power unit at Spata with expansion potential. Notable presence also includes Apto partnering with Dromeus Capital targeting hyperscalers needing massive computing power. Furthermore, ADMIE plans to construct another data center in Kryoneri, Attica. Crete presents interest due to its geography and evolving underwater connectivity links with Attica, Egypt, and Israel, enhancing its role as a potential data hub supported by energy adequacy advancements. According to Cushman & Wakefield’s 2025 report, the global data center market experiences explosive growth where mature markets like Virginia, London, and Beijing remain dominant but rising land costs and regulatory constraints push investors towards flexible options such as Greece. Demand for accessible land near energy sources, scalability needs, availability of green energy make Greece highly competitive. Artificial intelligence and machine learning are driving forces behind increased demand requiring low latency and high computational power pushing hyperscalers to seek new locations globally. Positioned strategically worldwide, Greece from Attica through Western Macedonia to Crete strengthens its digital infrastructure footprint. If planned investments materialize within schedule ensuring necessary energy and urban conditions, Greece could become a critical regional node managing data storage across Southeastern Europe and beyond.
