Currently, gas markets are going through a phase of transformation into global ones. They are largely following the American model of the spot trade market development with the building of LNG terminals for the internationalization and globalization of supply chains. All this greatly changes the structure of the relationship between the producers and consumers of long-term gas contracts, primarily in Europe. The availability of a ramified network of gas transmission pipelines in the territory of the European Union and the diversification of supplies through greater application of liquefied natural gas allows Europe to more effectively build its energy strategy. In particular, the stress is made on the creation of large hubs (junctions of inter-country flows) to turn the spot trade into a dominant mechanism of natural gas supplies.
