A €50 billion investment has been announced to build an ultra-large-scale AI data center park in Croatia, marking the largest single investment in the country’s history and a landmark project integrating energy storage and high-performance computing in Europe .
The project includes a 500MW photovoltaic system + 2GW/8GWh battery energy storage system (BESS) , paired with 4 independent 400kV transmission lines to boost grid capacity. Fully compliant with NVIDIA GW-scale AI factory standards, it addresses the critical bottleneck for large-scale AI computing expansion across Europe .
Backed by Croatia’s low-cost green energy advantages , the project will break ground in 2027 and begin full operations in Q1 2029, enhancing regional grid resilience and advancing the deep integration of energy transition and digital infrastructure .
