After a relatively modest start with 4 employees, by 2021, REGEA had grown to 35 employees with three regional offices and had increased its annual revenues twentyfold. 

REGEA’s main objective and role is promoting and encouraging regional sustainable development in the fields of energy and environmental protection through renewable energy sources and energy efficiency measures.

  • Over 40 completed EU projects through various programs (IEE, H2020, INTERREG, IPA, and more), in addition to over 20 ongoing EU projects; 
  • Coordination of the implementation of the first ELENA/EIB project in Croatia and key technical expert in the second: 
  • Project NEWLIGHT (2017-2019), achieved over €20 million investment in public lighting reconstruction; 
  • Project RePublEEc (2018-2021) aims to achieve over €50 million of investment in public lighting reconstruction in the City of Zagreb (City of Zagreb coordinator); 
  • Preparation of over 60 strategic and planning documents on the local and regional level (SEAPs, SECAPs, energy efficiency programs and action plans for Croatian counties); 
  • Preparation of strategic documents at the national level for various Croatian ministries (Long-term Renovation Strategy for Buildings (according to EPBD requirements), National Programme for Energy Retrofit of Culture and Heritage Buildings, National Programme for Energy Retrofit of Commercial Buildings, and more); 
  • Participation in national working groups on the topic of preparation of operational programs for 2021-2027; 
  • Significant number of awards and recognitions at the local, national and EU level (ManagEnergy, EUSEW, Energy Globe, and more);
