As part of a study (subchapter 4.3) by Frontier Economics, EWI quantifies the economic effects of the Nord Stream 2 pipeline using the European gas infrastructure model TIGER. The results of the simulation show that Nord Stream 2 will increase the supply of gas to Europe and thus reduce prices for European consumers. At the same time, it is shown that gas transits through Ukraine will continue to play an important role in the future and contribute to supplying Europe with gas at the lowest possible cost. Subchapter 4.3 was prepared by EWI on behalf of Frontier Economics. The entire short study was prepared by Frontier Economics on behalf of Nord Stream 2 AG.
