The CETAC (Clean Energy Transition Assistance Center) project facilitates strategic partnerships between municipalities, citizens, and businesses throughout the energy transformation process. Five pilot cities in the Czech Republic, Lithuania, Latvia, Poland, and Romania will test the first public services in this area. Training programs for municipal employees will be created to support measure implementation. The project aims to create a scalable model that cities throughout the EU can use as a tool for implementing Sustainable Energy and Climate Action Plans (SECAPs).
