A significant advancement in energy and technology is underway in Croatia, with plans for an extensive artificial intelligence campus in Topusko, spearheaded by Pantheon Atlas. This development will be entirely powered by renewable energy sources, marking a pivotal step towards sustainable technological infrastructure in the region.
The proposed facility will feature a 500 MW solar power plant and a robust battery storage system with a capacity of 2,000 MW and 8,000 MWh. This infrastructure is designed to directly support the energy needs of the campus. Greenvolt International Power, a company based in Portugal, has already committed to assisting with the development of energy solutions on-site through a signed letter of intent.
In addition to the campus itself, there are plans for substantial upgrades to the regional power network. The construction of four 400 kV transmission lines is anticipated to facilitate the integration of up to 5.2 GW of additional renewable capacity into Croatia’s electricity grid. This enhancement will significantly bolster the country’s capacity to manage and distribute clean energy.
The main data center within the complex is projected to achieve an installed capacity of 1 GW, with approximately 800 MW allocated for artificial intelligence computing workloads. The site will initially span over 125 hectares, with potential expansion up to 180 hectares based on future demand dynamics.
The first phase of construction is estimated at around €12 billion, with work expected to commence in early 2027, and operations slated for commissioning by early 2029. Over time, total investments could surpass €50 billion, accommodating additional hyperscale tenants as they establish operations within the facility.
This ambitious project is projected to have a substantial economic impact, generating approximately 3,000 jobs during its construction phase and around 1,500 permanent positions once operational. Local authorities in Sisak-Moslavina County have expressed their support through a formal cooperation agreement aimed at facilitating project development and ensuring its success.
