Compared to what ewi ER&S found in the study on “Impacts of Nord Stream 2 on the EU natural gas market”, the results of Regional Centre for Energy Policy Research (REKK) of Hungary yield different results on the price effects. This study shows that different assumptions about LNG import prices, Ukrainian transit capacities and the contracts of using them, and intra-EU infrastructure expansions are crucial to explain the differences between the ewi ER&S results and those of REKK.
