The Czech demonstration project is located in several areas in Czech Republic where ČEZ Distribuce operates distribution networks. The demonstration is not concentrated to one region in order to prove replicability and interoperability of designed solutions.

The Czech demonstration project will be partially built on the experience gained in the GRID4EU/ Smart Region Vrchlabí (a European project in the field of smart grids, renewable energies and energy transition which was finished in January 2016).

The Czech demonstration is focused on the implementation of solutions which are not so far usual in distribution systems but which have a strong potential for future roll out. Tested solutions within the demonstration cover the most urgent challenges of DSOs (increasing DER hosting capacity, EV charging stations implementation and energy storage). Beyond the technical developments, the demonstration also aims to propose grid codes and standards updates in order to secure future smoother integration of selected smart grid solutions
