Energy communities are formed to create integrated regional energy market in EU and non- EU neighboring countries. It attracts investors in generation and energy networks as it comes up with new stable regulations, so that it will ensure the supply is stable and continuous. Five EU countries (Germany, Italy, Sweden, Greece, Austria) with different policies are selected and simulations are done. Economic analysis for the 5 countries is done based on simulation results. The selected 5 EU countries shows a good economic result; therefore, it can be recommended to implement energy communities and cities by developing the directives. By transposition of policies of the energy community and implementing more subsidies or incentive will make a better contribution for the citizen partnership for creating CEC.
