Croatia has announced plans for a massive artificial intelligence data centre called Project Pantheon, valued at €50 billion and set to be built in Topusko (a town in Sisak-Moslavina County, central Croatia). Unveiled at the Three Seas Initiative Business Forum in Dubrovnik, the 1-gigawatt facility is expected to begin construction in 2027 and begin operations in early 2029, supported by a dedicated 500 MW solar power plant and 280 kilometres of new transmission lines. The project, backed by American institutional investors and Croatian industrial partners including the Koncar Group, is projected to create over 10,000 jobs directly and indirectly, while also enabling the integration of up to 5.2 GW of currently unused renewable energy into Croatia's national grid.
