Our mission
The mission of Green Energy Fair Zagreb 2026 is to connect industry, the public sector and experts in order to build a safe, flexible and sustainable energy system in the region together.
Batteries and energy storage systems are becoming crucial for grid stability and efficient use of renewable sources, while power system flexibility and smart consumption management are becoming essential tools for public and energy institutions.
The public sector has a key role to play in implementing the transition through infrastructure investments. The development of electric vehicle charging stations, e-buses and the electrification of public transport are becoming the norm, not the exception.
