The relevance of the research is due to the meaningfulness of the gas trunkline "Power of Siberia" for the development of the Eastern regions of Russia: their gasification and the emergence of new gas chemical and related industries, as well as the requirements for the reliability of its operation associated with the complex climate and natural conditions. On the basis of mathematical model of optimization of technical parameters of the projected trunkline taking into account reliability and the developed computing programs researches on the choice of an optimal variant and assessment of reliability of the site of trunkline " Power of Siberia" from the Chayanda field to Blagoveshchensk were executed. The analysis of results showed - the received optimal variant of construction of the site of trunkline on specifications will be coordinated with the version of the gas pipeline realized by PJSC Gazprom. Level of its reliability is estimated as rather high. However, gas trunkline "Power of Siberia" has ambiguous value for socio-economic development of Siberia and Far East of Russian Federation and gas supplies to China.
