Polish energy policy 2050 - An instrument to develop a diversified and sustainable electricity generation mix in coal-based energy system

The article aims to present the 2050 Energy Policy for Poland, which should facilitate the transformation of coal-based electricity generation system towards more sustainable and diversified energy mix. Comprehensive description and review of the current conditions of energy sector in Poland are accompanied with strengths and problems that need to be solved, taking into account European requirements. Additionally, in the paper the authors describe the development process of the Polish Energy Policy as they actively participated in the calculations of optimal energy mix for Poland. The manuscript presents the eMix model (energy mix optimization tool) developed by the authors, that constituted a background for Ministry of Economy to create Energy Policy. Hundreds of simulations scenarios were performed for the Ministry of Economy to provide the clear view of the electricity generation sector and to understand the impacts of all external stimuli to the mix. Assumptions for the model and results of calculations according to the policy scenarios are presented in the paper. Finally, the authors evaluate the final decisions of the policy makers, integrated in the Polish Energy Policy 2050, taking into account the challenges for the Polish power sector.
