Croatian electric equipment manufacturer Koncar has signed a contract worth 15.3 million euros with Solarna Elektrana, the Croatian subsidiary of Spanish company Acciona Energia, for the construction of a fully operational 400 kV substation as part of the Promina solar project.
The contract is based on a turnkey model, encompassing all phases of the project—from engineering and design to procurement, construction and the final handover of a fully functional facility.
Once completed, the substation will connect to the existing Konjsko and Velebit substations via high-voltage transmission lines. It will serve as the main grid connection point for the Promina solar power plant, channeling electricity into the national network and supplying power to approximately 69,000 households.
This will be the first 400 kV substation built in Croatia since 2004. When operational, the adjacent Promina solar plant will have an installed capacity of 150 megawatts, making it the largest solar power facility in both Croatia and the surrounding region.
