The article addresses the issue of natural gas supply to consumers in the Republic of Moldova in the context of terminating the transit contract for Russian natural gas on the territory of Ukraine on 31.12.2019 and the dispute between SAD "Gazprom" and NAK "Naftogaz Ukraine". Over the past years, the Republic of Moldova risks to lose the traditional route of Russian natural gas delivery. Under these conditions, in a short term, measures have been identified and implemented to create an alternative gas supply route for Moldovan consumers from the underwater pipeline of the Turkish flow (wire 2) through the trans-Balkan corridor in reverse. In these circumstances, it was concluded that only SC Vulcănești (Moldova) can be used to inject natural gas in reverse, for which it is necessary to create the prescribed upstream pressure regime.
