It is reported the parties have decided to agree on the use of the Ukrainian GTS on mutually beneficial terms. The issue of integration of Ukraine&#39;s integrated power grids into the European Network of Transmission System Operators for Electricity (ENTSO-E) was raised as well. Groysman stressed the move could be a good example for other areas and sectors of cooperation. As UNIAN reported earlier, the Nord Stream 2 project involves the construction of two strings of a gas pipeline with a total capacity of 55 billion cubic meters of gas a year from the Russian coast via the Baltic Sea to Germany. A new pipeline is expected to be built next to Nord Stream 1. The construction of Nord Stream 2 is to start in 2018 and end by late 2019. Poland, the Baltic states and Ukraine oppose the project.
